Source (SPAN) VLAN A VLAN whose traffic is monitored with use of the SPAN feature. Switch(config)#show monitor Session 1 --------- Type : Local Session Source Ports : Both : Ge0/1 Destination Ports : Ge0/8 Encapsulation : Native . The main restriction is that all the ports that relate to a particular session (whether source or destination) must belong to the same VLAN. I could do it with a passive network tap, of course; but it seems really strange to me that the 100D doesn't seem to expose an easy way to do this. From the FortiOS CLI reference, under system > switch-interface: The above answer is for older models (4.0). Each source port can be configured with a direction (ingress, egress, or both) to monitor. Port snooping lets you transparently mirror traffic from one or more source ports to a destination port.". It is in point of fact a nice and useful piece of info. Select Add Port Mirror. In the example in the Monitor VLANs with SPAN section, traffic that enters and leaves the specified ports is monitored. This list provides some restrictions. If you think that a device sends corrupted packets, you can choose to put the sending host and the sniffer device on a hub. All that traffic should be seen by the sniffer. For example, you can create PSPAN sessions on the configuration port that you have chosen to be a destination SPAN port. Complete the configuration as described in Table 169. It can be a physical port that is assigned to an EtherChannel group, even if the EtherChannel group is specified as a SPAN source. This lab will show you how to mirror traffic from a physical switch to your security onion IDS vm in vMware. The creation of a bridging loop typically occurs when the administrator tries to fake the RSPAN feature. A destination port cannot be a source port. It duplicated network traffic to one or more monitor interfaces as it transverse the switch. When a packet goes through a switch, these events occur: The packet is stored in at least one buffer. In order to prevent loops, the STP has been maintained on the RSPAN VLAN. A monitor port cannot be a dynamic-access port or a trunk port. RSPAN does not work when the RSPAN source session and the RSPAN destination session are on the same switch. The CatOS now has the ability to run several sessions concurrently, so it can have different destination ports at the same time. When you monitor a trunk port as a source port, all VLANs active on the trunk are monitored by default. In this way, you can view the packets. To configure SPAN through the CLI . A destination port has these characteristics: A destination port must reside on the same switch as the source port (for a local SPAN session). These are guidelines for the configuration of the SPAN feature on the Catalyst 2940, 2950, 2955, 2960, 2970, 3550, 3560, 3560-E, 3750, and 3750-E Series Switches: The Catalyst 2950 Switches can have only one SPAN session active at a time and can monitor only source ports. 5. mirror an internal port to a different internal port. In this session, port 6/1 to 6/2 is monitored, and at the same time, VLAN 3 to port 6/3 is monitored: Now, issue the show span command in order to determine if you have two sessions at the same time: Additional sessions are created. fortigate interface configuration cli fortigate interface configuration cli. This issue is also documented in Cisco bug IDCSCdy57506(registered customers only). NOTE: You must execute these commands from the VDOM that the default VLAN belongs to. Let us know. This issue is documented in Cisco bug ID CSCeg08870 (registered customers only) . In RSPAN mode, traffic is encapsulated in VLAN 4092. The configuration of a non-existent VLAN as an ingress VLAN is not allowed. From the article: The Switch Port Analyzer (SPAN) feature is now available for hardware switch interfaces on FortiGate models with built-in hardware switches (for example, the FortiGate-100D, 140D, and 200D etc.) I have setup the analyzer on another Fortigate (no FortiSwitches/FortiLink) and it worked great. Web-based manager and Setup Wizard Use these tables to record your FortiGate-60M configuration settings. After a switch boots, it starts to build up a Layer 2 forwarding table on the basis of the source MAC address of the different packets that the switch receives. I prefer to use CentOS for sniffers, but any OS will do. For Windows, download from http://www.wireshark.org The steps to configure this setup are outlined below: Configure WAN Links - FortiGate 1 config system interface edit "wan1" set vdom "root" set ip 10.10.11.2 255.255.255.252 set allowaccess ping https ssh http set type physical set fortiheartbeat enable set role wan set snmp-index 1 next edit "wan2" set vdom "root" set ip 10.10.12.2 255.255.255 . When you configure a SPAN destination port, you can specify whether or not the ingress feature is enabled and what VLAN to use to switch untagged ingress packets. Reflector Port A port that copies packets onto an RSPAN VLAN. SPAN traffic coming from other port types is not affected by VLAN filtering, which means that all VLANs are allowed on other ports. Required fields are marked *. The interface shows the port in this state in order to make it evident that the port is currently not usable as a production port. A monitor port cannot be enabled for port security. With some FortiSwitch models, you can configure multiple mirror destination ports with the following guidelines and restrictions: These restrictions apply to active mirrors. Each local SPAN session or RSPAN destination session must have a destination port (also called a monitoring port) that receives a copy of traffic from the source ports and VLANs. With this limitation in mind, I came up with a solution. The solution I came up with is as follows: 1. When you use Supervisor Engine 720 with an FWSM in the chassis that runs Cisco Native IOS, by default a SPAN session is used. How can I recognize one? Select to mirror traffic received, traffic sent, or both. A destination port can participate in only one SPAN session at a time. Can You Have Several SPAN Sessions Run at the Same Time? Click any interface where you plan to connect the PC in order to capture the sniffer traces. If doing more than one per switch (aggregate) you build the 'config switch mirror' commands so that the egress of both go to one mirror port and the ingress of both go to another port. How are others doing it? end. Therefore, you cannot have two SPAN sessions that use the same destination port. All SPAN ports are designed to capture both Rx and Tx traffic. A monitor port cannot be a multi-VLAN port. The best answers are voted up and rise to the top, Not the answer you're looking for? You use several command lines in order to configure the source and the destination with RSPAN. VLAN filtering affects only traffic forwarded to the destination SPAN port and does not affect the switching of normal traffic. Complete these steps to configure the SPAN: You can download CNA from theDownload Software (registered customers only) page. Port Fast Ethernet 0/1 (Fa0/1) monitors traffic that ports Fa0/2 and Fa0/5 send and receive. The packet is then stored in the shared memory. In this example, the session captures all incoming traffic for VLANs 1 and 3 and mirrors the traffic to port 6/2: Trunks are a special case in a switch because they are ports that carry several VLANs. This issue occurs due to a limitation in the packet forwarding architecture of the switch. If you have a multicast source that generates a multicast stream from behind the FWSM, you need the SPAN reflector. 4. You cannot convert an existing VLAN into an RSPAN VLAN. Why did you choose not to use DirectPath I/O? Looks like it is. The functionality works exactly as a regular SPAN session. The SPAN feature was introduced on switches because of a fundamental difference that switches have with hubs. For example, a port that is in shutdown mode can appear in the administrative source, but is not effectively monitored. Enter a name for the mirror. Ideally, I want to mirror one (or more) ports to another port, so that I can track the traffic that is flowing through it. Here, the mirrored ports are assigned to VLANs 1, 2, and 3. Copyright 2023 Fortinet, Inc. All Rights Reserved. The administrator creates a SPAN session that monitors the whole VLAN 1 on each core switch, and, to merge these two sessions, connects the destination port to the same hub (or the same switch, with the use of another SPAN session). Packets only enter the RSPAN VLAN in switches that are configured as RSPAN source. Incoming traffic is accepted and switched, with untagged packets classified into VLAN 7. Why does Jesus turn to the Father to forgive in Luke 23:34? Although this document is updated to reflect changes to SPAN, refer to your switch platform documentation release notes for the latest developments on the SPAN feature. Refer to the current Catalyst 8540 documentation for additional information. Please deactivate or delete another active session to make room. Thanks for sharing. If you try to activate an invalid mirror configuration, the system will display the Hardware active mirror session limit reached. The knowledge of RSPAN VLAN 100 is propagated automatically in the whole VTP domain. inpkts enable/disable This option is extremely important. A switch is not completely transparent with regard to the capture of traffic. Destination EtherChannels do not support the Port Aggregation Control Protocol (PAgP) or Link Aggregation Control Protocol (LACP) EtherChannel protocols; only the on mode is supported, with all EtherChannel protocol support disabled. On the Catalyst 2900XL/3500XL Series Switches, Cisco IOS Software Release 12.0(5)XU is used. To create a VLAN for the lab go to Network -> Interfaces, then select the interface that the VLAN for the tunnel is going to be and click on Create New. By default the system may have a hardware switch interface called LAN. The port can monitor the traffic that is forwarded to the Multilayer Switch Feature Card (MSFC). Solution 2. Use a list of one or more VLANs as a source, instead of a list of ports: With this configuration, every packet that enters or leaves VLAN 2 or 3 is duplicated to port 6/2. When both ingress and a trunk encapsulation are specified on a SPAN destination port, the port goes forwarding in all active VLANs. Select to mirror traffic received, traffic sent, or both. This feature is available on the Catalyst 5500/5000 and 6500/6000 Switches, code version CatOS 5.1 or later. S1 is called a source switch. In FortiGate 6.2 and FortiSwitch 6.2 ERSPAN is supported and will likely meet your requirement. Therefore, the sniffer does not see this traffic: In this configuration, the sniffer only captures traffic that is flooded to all ports, such as: Multicast traffic with CGMP or Internet Group Management Protocol (IGMP) snooping disabled. Any port configured as a src-ingress or src-egress port in one mirror cannot be configured as a destination port in another mirror. Create an untagged Port Group called SPAN Target Select the SPAN check box, then select a source port from which traffic will be mirrored. Imagine that you want to use SPAN on the traffic in VLAN 2 for ports 6/4 and 6/5. Click on Port Forwarding. A reflector port receives copies of sent and received traffic for all monitored source ports. ERSPAN is by far the easiest way to do this type of thing if its available to you. The command is: Because there can only be one destination port per session, the destination port identifies a session. This article explains how to setup SPAN (Port Mirroring) using ports associated to underlying switch chip/driver. So, lets test it. If you do not specify any interface in the port monitor command, all other ports that belong to the same VLAN as the interface are monitored. When a VLAN filter list is specified, only those VLANs in the list are monitored on trunk ports or on voice VLAN access ports. A 10/100 port reflects at 100 Mbps. The reflector port loops back untagged traffic to the switch. You cannot mix source VLANs and filter VLANs within a session. The Switch Port Analyzer (SPAN) feature is now available for hardware switch interfaces on FortiGate models with built-in hardware switches (for example, the FortiGate-100D, 140D, and 200D etc.). communities including Stack Overflow, the largest, most trusted online community for developers learn, share their knowledge, and build their careers. How to troubleshoot crashes detected by Google Play Store for Flutter app, Cupertino DateTime picker interfering with scroll behaviour. Similarly, when you see a corrupted packet on your sniffer in the scenario in this section, you know that the errors were generated at step 3, on the egress segment. The Catalyst 4500/4000, 5500/5000, and 6500/6000 Series Switches allow you to collect only egress (outbound) or only ingress (inbound) traffic on a particular port. This will SPAN ports 5/1 through 5/5. Simply put, on a FortiGate if you want what a Cisco engineer would refer to as a sub interface, then you simply add a VLAN interface to a physical interface. Each time a satellite retrieves the packet from the shared memory, this index is decremented. In this case, issue the port monitor interface command in order to list the source ports that you want to monitor. A destination port receives copies of sent and received traffic for all monitored source ports. In order to achieve the flooding, learning is disabled on the RSPAN VLAN. Every line card in the switch starts to store this packet in internal buffers. Save the configuration. Be careful that a port in the monitor state does not run the Spanning Tree Protocol (STP) while the port still belongs to the VLAN of the ports that it mirrors. Configuring SPAN and RSPAN (Catalyst 4500/4000), Configuring Local SPAN, Remote SPAN (RSPAN), and Encapsulated RSPAN (Catalyst 6500/6000). The traffic that is monitored by SPAN is not directly copied to the destination port, but flooded into a special RSPAN VLAN. There can even be several destination ports. The administrator achieves the goal. A monitor port is a destination SPAN port in Catalyst 2900XL/3500XL terminology. Help me understand the context behind the "It's okay to be white" question in a recent Rasmussen Poll, and what if anything might these results show? By default the system may have a hardware switch interface called LAN. Configure a SPAN session using the spare vmnic's switchport as the SPAN target 9. I added a member to the FortiLink interface and setup port spanning to the analyzer, but it is not receiving any traffic. In order to monitor traffic across a WAN or different networks, use Encapsulated Remote SwitchPort Analyser (ERSPAN). spanning port 15/1On the Catalyst 6500/6000, you can use port 15/1 (or 16/1) as a SPAN source. In this example, we monitor traffic from VLAN 5 that is spread across two switches: On the remote switch, use this configuration: In the previous example a port was configured as a destination port for both local SPAN and the RSPAN to monitor traffic for the same VLAN that resides in two switches. 6. I had to span each fortilink interface on the fortiswitch side though to another available fortiswitch port. Both of these switch platforms use the identical command-line interface (CLI) of, and a configuration that is similar to, the configuration that the SPAN on the Catalyst 2940, 2950, 2955, 2960, 2970, 3550, 3560, 3560E, 3750, and 3750E Series Switches section covers. The traffic is then placed on the RSPAN VLAN and flooded to any trunk ports that carry the RSPAN VLAN. Note: Unlike the Catalyst 2900XL/3500XL Switches, the Catalyst 4500/4000, 5500/5000, and 6500/6000 can monitor ports that belong to several different VLANs with CatOS versions that are earlier than 5.1. The FortiGate doesn't care which protocol is running over the port 443, so you just need to create a policy and select the corresponding interfaces/addresses and as service you can select HTTPS. Create a New Inbound Network Security Group Rule for TCP Port 8443. The information in this document was created from the devices in a specific lab environment. To enable SPAN on a hardware switch via the GUI, go to System > Network > Interfaces and edit a hardware switch interface. Note: The commands in the configuration are not supported on the Catalyst 2950 with Cisco IOS Software Release 12.0(5.2)WC(1) or any software that is earlier than Cisco IOS Software Release 12.1(6)EA2. Yes. Because the source satellite knows the destination, this satellite also transmits an index that specifies the number of times that this packet is downloaded by the other satellites. This feature is in contrast to Remote SPAN (RSPAN), which this list also defines. Even switches that are not on the path to a destination port, such as S2, receive the traffic for the RSPAN VLAN. Refer to these documents for the related configuration: Configuring SPAN & RSPAN(Catalyst 6500/6000), Configuring SPAN & RSPAN (Catalyst 4500/4000). The fields include the destination ports. The packet structure in the PDT is now updated with a reference to the virtual path and counter. To configure one-to-one NAT: Go to Networking > NAT. When it reaches 0, the shared memory buffer releases. To continue creating a port mirroring session, select sources and traffic direction for the new port mirroring session. A new hardware switch interface can also be created. Select from the excluded ports which ports to include for ingress mirroring and egress mirroring. Remi: I get alerted for the tags fortinet and fortigate, so I came here. Give the new interface a name (and alias if required) > Interface Type should be VLAN > Select the parent physical interface > Add the VLAN ID (Tag) and specify an IP address of the interface. 1 Supervisor Engine 720 supports two RSPAN source sessions. Other ports and the management interface are configured in the default VLAN 1.

For newer models (5.0-5.4), look here. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product. Next step is to get the sniffer VM setup. In order to monitor traffic for a particular vlan that resides in two switches directly connected, configure these commands on the switch that has the destination port. Aha, nevermind. The ERSPAN traffic is sent to a specified IP address, which must be reachable by IPv4 ICMP ping. From the System menu, select Virtual Domain. Select Load balancers in the search . The default is enable. The performance of the SPAN feature depends on the packet size and the type of ASIC available in the replication engine. 3. You could also create a 2-port hardware switch on the 60E. By default, the system may have a hardware switch interface called a LAN. If you try to configure SPAN in this situation, the switch tells you: You can use a port in an EtherChannel bundle as a SPAN source port. In this case, the port I am using as the source is a link between two switches (the one in my study and the switch in the garage where the servers are). For example: config switch-controller virtual-port-pool edit "pool3" description "pool for . Asking for help, clarification, or responding to other answers. You can have source VLANs or filter VLANs, but not both at the same time. The port captures traffic that is software-routed or directed to the MSFC. Spanning tree is automatically disabled on a reflector port. A SPAN port (sometimes called a mirror port) is a software feature built into a switch that creates a copy of selected packets passing through the device and sends them to a designated SPAN port. The obvious answer is to use RSPAN, but in this particular case the switch did not support RSPAN so that wasnt an option. What happened to Aham and its derivatives in Marathi? With the issue of theset span enable command, a user reactivates the stored SPAN session. The following example configuration includes three ingress ports, three egress ports and four destination ports. To enable SPAN on a hardware switch via the GUI, go to System > Network > Interfaces and edit a hardware switch interface. The specification of an ingress VLAN is not required when ISL encapsulation is configured, as all ISL encapsulated packets that have VLAN tags. Refer to the Enabling Switch Port Analyzer section of Managing Switches in order to configure SPAN on a Catalyst 2950 with software that is earlier than Cisco IOS Software Release 12.1(6)EA2. S2 and S3 are intermediate switches. Network Analyzer/Security Device Connected to SPAN Destination Port is Not Reachable, Local SPAN, RSPAN, and ERSPAN Destinations, Getting Started Guide for the Catalyst Express 500 Switches 12.2(25)FY, Getting Started Guide for the Catalyst Express 520 Switches, Release Notes for Catalyst 2948G-L3 and Catalyst 4908G-L3 for Cisco IOS Release 12.0(10)W5(18g), SPAN on the Catalyst 2940, 2950, 2955, 2960, 2970, 3550, 3560, 3560E, 3750, and 3750E Series Switches, Local SPAN, RSPAN, and ERSPAN Session Limits, Configuring Local SPAN, Remote SPAN (RSPAN), and Encapsulated RSPAN, Configuring Local SPAN, RSPAN, and ERSPAN, Configuring Local SPAN, Remote SPAN (RSPAN), and Encapsulated RSPAN - Catalyst 6500 Series Cisco IOS Software Configuration Guide, 12.2SX, How to configure SPAN and RSPAN on Cisco Catalyst 4500 switches that run Cisco IOS Software, A SPAN destination port is shown as "not connected" and does not communicate with the rest of the network, Technical Support & Documentation - Cisco Systems, Yes Supervisor 2T with PFC4, Supervisor 720 with PFC3B or PFC3BXL running Cisco IOS Software Release 12.2(18)SXE or later. Each ingress and egress port is mirrored to only one destination port. Currently, a Catalyst 6500/6000 can have up to 24 RSPAN destination ports, for one or several different sessions. Source (SPAN) port A port that is monitored with use of the SPAN feature. Always set the destination port before setting the src-ingress or src-egress ports. Flutter change focus color and icon color but not works. You can use normal SPAN in 6.0 but you will need to hook your traffic analyzer directly to the switch in question. How to print and connect to printer using flutter desktop via usb? Put the TCP and UDP ports of the Fortinet Fortigate server in the boxes in your router. The SPAN feature on a Layer 3 switch is called port snooping. When you configure a SPAN session to monitor the port, the destination interface shows the state down (monitoring), by design. Refer to Configuring Local SPAN, Remote SPAN (RSPAN), and Encapsulated RSPAN - Catalyst 6500 Series Cisco IOS Software Configuration Guide, 12.2SX for more information on ERSPAN. If you do not specify the encapsulation keyword, the packets are sent untagged, which is the default in Cisco IOS Software Release 12.1(11)EA1 and later. Critical issues have been reported with the following SDK versions: com.google.android.gms:play-services-safetynet:17.0.0, Flutter Dart - get localized country name from country code, navigatorState is null when using pushNamed Navigation onGenerateRoutes of GetMaterialPage, Android Sdk manager not found- Flutter doctor error, Flutter Laravel Push Notification without using any third party like(firebase,onesignal..etc), How to change the color of ElevatedButton when entering text in TextField, Fortigate Firewall - DMZ vs Interface ports, Fortinet multiple WAN IP to several ports, DHCP relay through Fortigate 60B firewall isn't working. When a satellite receives a packet from a port, the packet is split into cells and sent to the switching fabric via one or more channels. This information in this document uses CatOS 5.5 as a reference for the Catalyst 4500/4000, 5500/5000, and 6500/6000 Series Switches.
