Managing Port Mirroring

Port mirroring is a troubleshooting tool that copies, or mirrors, all traffic received or transmitted on a designated
port to another mirror port. If a protocol analyzer were attached to the target port, the traffic stream of valid frames
on any source port is made available for analysis.
Select a target port that has a higher speed than the source port. Mirroring a 100 Mbps port onto a 10 Mbps port
may result in an improperly mirrored stream.
Frames will be dropped if the full-duplex rate of frames on the source port exceeds the transmission speed of the
target port. Since both transmitted and received frames on the source port are mirrored to the target port, frames
will be discarded if the sum traffic exceeds the target port's transmission rate. This problem reaches its extreme in
the case where traffic on a 100 Mbps full-duplex port is mirrored onto a 10 Mbps half-duplex port.
Invalid frames received on the source port will not be mirrored. These include CRC errors, oversized and
undersized packets, fragments, jabbers, collisions, late collisions and dropped events).
NOTE
Port mirroring has the following limitations:
• The target port may sometimes incorrectly show the VLAN tagged/untagged format of the mirrored
frames.
• Network management frames (such as RSTP, GVRP, etc. ) may not be mirrored.
