3Com 4500 switch SPAN (port mirroring)

February 12, 2013

In the example below I am creating monitoring on port 50 for port 49. My port 49 is my uplink port for that 3Com 4500 48+2 port switch:

interface GigabitEthernet1/0/49
port link-type trunk
port trunk permit vlan all
port trunk pvid vlan 10
mirroring-group 1 mirroring-port both
#
return
[SD-LIB-3C4500-50P]dis cur int g1/0/50
#
interface GigabitEthernet1/0/50
port link-type trunk
port trunk permit vlan all
port trunk pvid vlan 10
mirroring-group 1 monitor-port
#
return
[SD-LIB-3C4500-50P]display mirror 1
mirroring-group 1:
type: local
status: active
mirroring port:
GigabitEthernet1/0/49  both
monitor port: GigabitEthernet1/0/50
