Hi List, We are using Brocade XMR routers and on one of these devices we need to make a mirror of a specific VLAN. Normally we would use a port mirror, but with the VLAN residing on a 10Gb port, this is not an option.
I've found a doc on the Brocade site explaining on how-to do this (http://community.brocade.com/docs/DOC-2413), but I think that this is for ingress only, this after some testing. I've created a testsetup; On another XMR I've created a VLAN (VLAN 60)+ VE and in the vlan I've added two tagged ports, ethe 2/19 and 2/20. Port 2/10 will be the mirror-port, the source-port will be 2/19. On the VE, a /29 subnet is configured. On each of the tagged ports I've connected a switch and each switch has one IP address out of the /29. I then ping switch B from switch A (this is working). I then created the mirror: /XMR# access-list 400 permit any any 60 mirror XMR# access-list 400 permit any any XMR# interface ethernet 2/19 XMR# mac access-group 400 in XMR# acl-mirror-port ethernet 2/10/ When I hookup a laptop on port 2/10 and look via tcpdump, I'm not receiving ingress and egress traffic, I'm only seeing the ping requests or the ping replies (depending which switch sends the ping requests), but not both. Is there a way to configure a VLAN mirror so that we can see both ingress and egress traffic?
