Displaying And Maintaining Port Mirroring - 3Com E4500-24 Cli Configuration Manual

To do...
Enter system view
Create a VLAN and enter VLAN
view
Configure the current VLAN as
a remote-probe VLAN
Return to system view
Enter the view of the Ethernet
port connecting to the source
switch or an intermediate
switch
Configure the current port as
trunk port
Configure trunk port to permit
packets from the remote-probe
VLAN
Return to system view
Create a remote destination
mirroring group
Configure the destination port
for the remote destination
mirroring group
Configure the remote-probe
VLAN for the remote
destination mirroring group
When configuring a destination switch, note that:
A Switch 4500 acting as the destination switch in remote port mirroring networking does not
support bidirectional packet mirroring (the both keyword).
The destination port of remote port mirroring cannot be a member port of an existing mirroring
group, a fabric port, a member port of an aggregation group, or a port enabled with LACP or STP.
Only an existing static VLAN can be configured as the remote-probe VLAN. To remove a
remote-probe VLAN, you need to restore it to a normal VLAN first. A remote port mirroring group
gets invalid if the corresponding remote port mirroring VLAN is removed.
