Cisco nexus packet capture for VRF vlan interface

[MonkeyBear007]

Need to packet capture a vrf vlan interface for traffic what is the best way

[pieterh]

I do not understand the question

vlan interface is Layer-2, vfr is Layer-3.
-> just specify vlan as monitor source?

[MonkeyBear007]

nexus doesn't let use the VRF vlan at layer 3

[pieterh]

cna you publish the command you used and the response you got?

you need to specify the type of interface
     source interface type slot/port [rx | tx | both]
or specify the vrf in the monitor session command
monitor session <id> source vrf <name>

Hi,

   It doesn't matter if the interface is in VRF or GRT. If you want a packet capture, use this guide for Ethanalyzer: https://www.cisco.com/c/en/us/support/docs/switches/nexus-7000-series-switches/116136-trouble-ethanalyzer-nexus7000-00.html

If you want a SPAN/RSPAN, use these guides:

You can also take a look on this self-explanatory Cisco Live Presentation:

I opened a ticket with support, and they didn't see it, so I need to open another one to figure out why.
