B. RSPAN traffic is sent to VLANs 222 and 223. A source port cannot be a destination port. A SPAN session can support multiple destination ports only if they are on the same VLAN.D.EACH SPAN session supports only one source VLAN or interface. On the NetVanta 1550 we port mirrored switch port 24 (uplink port servicing / connected to the NetVanta 1534 switch) as the source. So we used the CLI command 'monitor session', to port mirror ports 1-23 (Source ports) and made port 24 the destination port. Which command flags an error if it is added to this configuration? set associated-interface <interface name> set type ipmask set subnet <IPv4 address> <mask> or <IPv4 address/mask> next end When using the "set subnet." syntax, the mask definition can be denoted in bits. E. A switch can support only one local SPAN session at a time. destination. edledge-switch# conf t edledge-switch (config)# monitor session 1 source interface port-channel 1 both Destination Interface Here we can select either rx or tx or both flow as source traffic. It worked when I did: #monitor session 1 destination interface GigabitEthernet 2/48 And I can see packets on G2/48 like I should. To start the capture use below command. Also, interface ranges such as fa 0/25 - 26 are possible, and interface list, such as fa 0/24,fa 0/26, if you would like to monitor several clients at the same time. cisco monitor session vlan. This is good for when you ONLY want to monitor specific vlan traffic between switches because you will not be able to use the filter AND add the vlan as a source at the same time. C. An error is flagged for configuring two destinations. interface-name. Switch (config)#monitor session 1 source interface fa0/1 Switch (config)#monitor session 1 destination interface fa0/2 You can verify the configuration like this: Switch#show monitor session 1 Session 1 --------- Type : Local Session Source Ports : Both : Fa0/1 Destination Ports : Fa0/2 Encapsulation : Native Ingress : Disabled For interface-id, specify the source port to monitor. Tunnel interface supported as source ports for an ERSPAN source session are GRE, IPinIP, SVTI, IPv6, IPv6 over IP tunnel, Multipoint GRE (mGRE) and Secure Virtual Tunnel Interfaces (SVTI).

The monitoring of traffic received on port 1 is disabled, but traffic sent from this port continues to be monitored. When you are removing a port from a SPAN session, you would use the following example command no monitor session 1 interface fastethernet 0/2, but I'm unsure if that command works on the Nexus series. For session number, specify 1 or 2. For example, building off of your example, I need an additional port mirror so that in addition of mirroring port 8 on port 1, I'd need to monitor port 12 on port 14. The interface specified must already be configured as a trunk port. Open User Access Verification S1# telnet 192.168.1.1 Trying 192.168.1.1 . monitor session 1 source interface fa 0/24 Here, the session number can be from 1 to 66, you could also specify a VLAN or an ethernet channel. Specifies the SPAN source. The following example shows how to configure SPAN session 1 to monitor bidirectional traffic from source interface Gigabit Ethernet 2/1 and destination interface Gigabit Ethernet 2/4: Switch# configure terminal Switch (config)# monitor session 1 type local Switch (config-mon-local)# source interface gigabitethernet 2/1 console (config)#monitor capture mode file. C2960(config)# monitor session 1 source interface range fe 0/1 - 23. By default, ERSPAN monitors all traffic, including multicast and Bridge Protocol Data Unit (BPDU) frames. I have looked through the config guides, and all they show is how to add ports, but they don't show how to remove ports from a SPAN session. Switch(config)# monitor session 1 source interface gigabitethernet0/1 Switch(config)# monitor session 1 destination interface gigabitethernet0/2 encapsulation replicate Note: Switches 2940, 2950, 2955, 3550 use "dot1q" in place of "replicate" Switch(config)# end This example shows how to remove port 1 as a SPAN source for SPAN session 1: And port mirror switch port #3 as the destination port. To create a SPAN source session to monitor the traffic that is bridged into a source VLAN, use the monitor session session_number source vlan vlan-id command. session-number. Specify the characteristics of the source port (monitored port) and RSPAN session. Other possible options to capture the traffic are listed below: To save the CPU captured outputs in PCAP file in flash. It can be a list or a range. This technique allows a security tester to connect to each switch and collect a representation of the network traffic that exists locally within or transfers via uplinks through the switch. For interface-id, specify the source port to monitor. tpw-sw1#show monitor Session 1 --------- Type : Local Session The password is cisco. Otherwise, I would recommend 'monitor session 1 vlan 12 tx' for simplicity. The RSPAN VLAN is replaced by VLAN 223. I think the additional port mirror should look something like the lines below, but I cannot figure out how to add a session: console (config)#monitor session 2 source interface 1/g12 Twitter's origins lie in a "daylong brainstorming session" held by board members of the podcasting company Odeo. console (config)# monitor capture Start all. A session can have up to eight source ports and one destination port with the same session number. Flow-base monitor will allow you to select what traffic you want to monitor on the VLAN interface via an ACL that you create and then apply to the source.
