HP 2920 series - Port Mirroring (SPAN)

Question

Looking to enable multiple mirrored ports on a 2920, where port traffic is monitored and mirrored (SPAN) to other ports on the same switch.

 

Been able to enable 1 mirrored port but, that's it. Does anyone know if the J9726A supports 2+ mirrored ports and if so, how to configure those?

Answer

You are limited to 1 mirrored port on the 2920 switches. I don't have one to check against, but if you are able to assign multiple mirrored ports you would be able to see it listed when you perform "mirror ?" or "mirror-port ?" on the console, this is the output from a 5400zl Chassis (K class firmware)  & 3800 series (also K class) which allows 4 seperate mirrored sessions...

 

SWITCH(config)# mirror
 endpoint              Remote mirroring destination configuration.
 <1-4>                 Mirror destination number.

and here's the output from a 2620 (RA class firmware) switch that only allows the one...

 

SWITCH(config)# mirror-port
 [ethernet] PORT-NUM   Define the mirror port for diagnostic purposes.
