I'm trying to do a simple port mirroring on an FCX-48GS switch. I want traffic from ethernet 1/1/22 to be copied to ethernet 1/1/43, using the following configuration:
switch1-1(config)#mirror-port ethernet 1/1/43
switch1-1(config)#interface ethernet 1/1/22
switch1-1(config-if-e1000-1/1/22)#monitor ethernet 1/1/43 both
Show mirror gives me the following output:
Mirror port 1/1/43
Input monitoring : (U1/M1) 22
Output monitoring : (U1/M1) 22
As I understand it this looks correct, but I don't see any traffic on port 1/1/43 (using a windows pc with wireshark) when a client is sending traffic on port 1/1/22. Am I missing something?
port 1/1/22 belongs to two vlans with Dual-mode configured (to allow PCs and phones on the same port), does this need any extra configuration to mirror?
