A SPAN session is an association of a destination interface with a set of source interfaces. You can configure SPAN sessions using parameters that specify the type of network traffic to monitor. SPAN sessions allow you to monitor traffic on one or more interfaces and can send ingress traffic, egress traffic, or both to one or more destination interfaces. SPAN sessions do not interfere with the normal operation of the Cisco EtherSwitch module. The Cisco EtherSwitch network modules and HWICs support one SPAN session; however, frames on the SPAN port contain an 802.1q tag. The Cisco EtherSwitch service modules do not have this limitation.
The EtherSwitch modules supports these SPAN features:
â¢ Allowance of one active SPAN session at any given time
â¢ The mirror of all 16/36 ports in one SPAN session
â¢ Allowance of only one destination
â¢ The need for all SPAN ports to be on the same EtherSwitch
â¢ Ability of the module to analyze EtherChannel via SPAN
