The remote-tag keyword followed by the tag is added in the command to enable mirroring. For example, you can establish ports 24 and 25 as monitor ports, from which any mirrored packets are transmitted with an additional VLAN tag containing a VLAN ID of 1000:
Remote mirroring can also be enabled to a single port, without the port-list and loopback-port keywords.
enable mirror to port-list 24,25 loopback-port 1 remote-tag 1000
The show mirror output displays the remote tag when remote mirroring is configured.
enable mirror to port 25 remote-tag 1000
