Usage Guideline The following applies to monitoring:
• A destination port and source port cannot be the same port.
• A port-channel can be specified as a monitor source or as a monitor des-
tination.
• A channel-group member port cannot be specified as a monitor source
port or destination port.
• For a monitor session, multiple source interfaces can be specified. How-
ever, only one destination interface can be specified. An interface cannot
be a source interface of one session and destination port of another ses-
sion simultaneously.
• For a destination port, all the layer 2 settings configured for this port are
all ineffective.
