Configure Switched Port Analyzer (SPAN)

The Switched Port Analyzer (SPAN) feature, which is sometimes called port mirroring or port monitoring,

selects network traffic for analysis by a network analyzer. The network analyzer can be a Cisco SwitchProbe

device or other Remote Monitoring (RMON) probe. The switch supports only the Local SPAN and does not

support Remote SPAN.

The destination port should be configured with the Diagnostics Smartport role. This can only be done using

the Cisco Network Assistant software. Refer to SPAN on Catalyst Express 500 for configuring the Catalyst

Express 500 switch to monitor traffic.
