Does anybody know the specifications about port mirroring funcionality for Cisco SRW2048 48-Port Gigabit Switch?
I need to know about:
1.- Is there any limit in port mirroring sessions?
2.- Can one target port receive traffic from multiple ports?
This switch only supports 1 session - i.e. 1 target mirror port. SRW and SFE/SGE switches can have up to 8 source ports while the SLM switches can have up to 4 source ports.In every case there is only one target mirror port.
I'm not sure what you mean by 'sessions' , but i'll explain a common sense limit on mirroring a little later.
But for a test, I pulled up my SRW2008P, even though not a SRW2048 and produced the following screen shot at the following community location.
You can usually mirror both TX and RX traffic from about four ports to a fifth port, even on the SRW2048. But you can, as you wish, limit to only RX traffic from the switches perspective.
In terms of limits to mirrored sessions, there is a common sense limit .
If the four switch ports to be mirrored are running at very high port utilisation and you are capturing 3 or 4 switch ports and directing that traffic to a 5th switch port for mirroring purposes, expect packets to be dropped as it egresses out to the mirrored port. I hope that make sense. You can't have 4Gbits/sec egressing out a mirrored ports to your PC or capturing utility. :-)
