Data displays only for the ports that support plug-in optical modules and only when 
the SFP transceiver in use supports the digital diagnostic standard SFF-4872.

The Optical Module Status Table contains the following fields:

•

Port—The port number on which the cable is tested.

•

Temperature—The temperature (C) at which the cable is operating.

•

Voltage—The voltage at which the cable is operating.

•

Current—The current at which the cable is operating.

•

Output Power—The rate at which the output power is transmitted.

•

Input Power—The rate at which the input power is transmitted.

•

Transmitter Fault—Indicates if a fault occurred during transmission.

•

Loss of Signal—Indicates if a signal loss occurred in the cable.

Use the port and VLAN mirroring feature to send network traffic on a port or VLAN 
copied to another port for analysis by a network analyzer.

A mirroring session consists of a destination probe port and at least one source 
port or VLAN. A mirror copy of the traffic on the source port(s) being probed are 
transmitted from the source port or VLAN to the destination probe port. A network 
analyzer can be connected to a destination probe port to analyze network traffic.

A port configured as a destination probe port acts as a mirroring port as long as 
the session is operationally active. When the session is not active, the port 
transmits and receives traffic based on the other configuration parameters.

When a port is configured as a probe port, the switch does not forward or receive 
any traffic or respond to a ping.
