enable mirror

42-1 config mirror
Description
This command is used to configure a mirror port − source port pair on the Switch. Traffic from any
source port to a target port can be mirrored for real-time analysis. A logic analyzer or an RMON
probe then can be attached to study the traffic crossing the source port in a completely unobtrusive
manner. When mirroring port traffic, please note that the target port must be configured in the
same VLAN and operates at the same speed as the source port. If the target port is operating at a
lower speed, the source port will be forced to drop its operating speed to match that of the target
port.
Format
config mirror port <port> {[add | delete] source ports <portlist> [rx | tx | both]}
