I have the following config on a Brocade XMR, running IronWare 5.6.0c.
Will the traffic mirrored to e 1/13 keep it's VLAN tags, so I can distinguish where it came from? Or will the tags be stripped and all be untagged?
And for bonus points, if it will be untagged, is there any way to keep the tags?
mirror ethernet 1/13
interface ethernet 2/16
enable
mon ethernet 1/13 both

The documentation says: "NOTE: If a port is configured as a mirror port, all traffic sent from that port will retain the encapsulation of the port being monitored and not add the encapsulation of the Egress port.". So it's a 1:1 packet copy, any tagging is preserved.
