Set 3com SuperStack 3 Switch 4500 Port Mirroring (SPAN)

Saturday, May 24th, 2008

I do not have the intention to promote any products in this blog. This post is for me to record down the setup and it is pretty simple to do it in console or remote session.

<4500> system-view
[4500] interface Ethernet 1/0/1
[4500-Ethernet1/0/1] mirroring-port ?
  both      Mirror the inbound and outbound packets of the interface
  inbound   Mirror the inbound packets of the interface
  outbound  Mirror the outbound packets of the interface
[4500-Ethernet1/0/1] mirroring-port both
[4500-Ethernet1/0/1] quit
[4500] interface GigabitEthernet 1/0/27
[4500-GigabitEthernet1/0/27] monitor-port
[4500-GigabitEthernet1/0/27] quit
[4500] display mirror
   Ethernet1/0/1              both

Both inbound and outbound traffic will be mirrored to Gigabit Ethernet 1/0/27, and you are able to get your monitoring server to receive the traffic from this monitoring port.

That’s all for today.
