Port Configuration

You can mirror traffic from any source port to a
target port for real-time analysis. You can then
attach a logic analyzer or RMON probe to the
target port and study the traffic crossing the
source port in a completely unobtrusive manner.
Command Usage
• Monitor port speed should match or exceed source port speed, otherwise traffic
may be dropped from the monitor port.
• All mirror sessions must share the same destination port.
• When mirroring port traffic, the target port must be included in the same VLAN as
the source port when using MSTP (see Spanning Tree Algorithm Configuration on
page 3-192).
