Configuring Port Monitoring
186 | Port Monitoring
To configure port monitoring, use the following example:
Step Task Command Syntax Command Mode
1 Verify that the intended monitoring port has no
configuration other than no shutdown (Figure 15-3).
2 Create a monitoring session using the command monitor
session from CONFIGURATION mode (Figure 15-3).
3 Specify the source and destination port and direction of
traffic (Figure 15-3).
To display information on currently configured port-monitoring sessions, use the show monitor session
command from EXEC Privilege mode (Figure 15-3).
Figure 15-3. Displaying Port-based Monitoring
show interface EXEC Privilege
monitor session CONFIGURATION
source MONITOR SESSION
Note: By default, all uplink ports are assigned to port-channel (LAG) 128 and the destination port in a port
monitoring session must be an uplink port. When you configure the destination port using the source
command, the destination port is removed from LAG 128. To display the uplink ports currently assigned to
LAG 128, enter the show lag 128 command.
