Chapter 30 Monitoring Network Traffic Using SPAN
SPAN Sessions
•
VSAN 1 as a source does not include the TE port fc1/1 as the port VSAN does not match VSAN 1.
SPAN Sessions
Each SPAN session represents an association of one destination with a set of source(s) along with
various other parameters that you specify to monitor the network traffic. One destination can be used by
one or more SPAN sessions. You can configure up to 16 SPAN sessions in a switch. Each session can
have several source ports and one destination port.
To activate a SPAN session, at least one source and the SD port must be up and functioning. Otherwise,
traffic will not be directed to the SD port.
To temporarily deactivate (suspend) a SPAN session use the suspend command in the SPAN submode.
The traffic monitoring is stopped during this time. You can reactivate the SPAN session using the no
suspend command.
A source can be shared by two sessions, however, each session must be in a different direction—one
ingress and one egress.
