Port mirroring on nortel 5520 switch stack

Recently had cause to set this up, and although i’m familiar and comfortable doing this on cisco stuff, never had cause to do it on our nortels.

The config below is what is required on the cli – if you have access to the web interface its pretty straight forward there too.

port-mirroring mode xrxorxtx monitor-port 1/23 mirror-port-X 2/3 mirror-port-Y 2/4

According to the nortel documentation this mirrors ports 2/3 and 2/4 to port 1/23 – however in practice and looking through the bugs list the firmware we ran does not actually support monitoring 2 ports, so we ended up falling back to just the single mirror.

Very short first post…

The following Cisco IOS – Cisco IOS Software, C3750 Software (C3750-IPBASE-M), Version 12.2(35)SE5, RELEASE SOFTWARE (fc1)

Doesnt support IP policys

After allowing me to configure the ACL’s and then the route-map for my policy I discovered that this version of the IOS on a 3750G switch stack doesnt support this feature.

Doh!

UPDATE: This version doesnt support it either – Cisco IOS Software, C3750 Software (C3750-ADVIPSERVICESK9-M), Version 12.2(44)SE, RELEASE SOFTWARE (fc1)
