Monitoring and Analyzing Switch Operation
Interface Monitoring Features
Selecting or Removing Monitoring Source Interfaces. After you con­
figure a monitor port you can use either the global configuration level or the
interface context level to select ports, static trunks, or VLANs as monitoring
sources. You can also use either level to remove monitoring sources.
Syntax: [no] interface < monitor-list > monitor
[no] vlan < vid > monitor
where:
< monitor-list > Includes port numbers and static trunk names
such as a4,c7, b5-b8, trk1
.
< vid > Allows monitoring of one VLAN.
Identifies the switch elements to monitor through the currently
configured monitor port. You can monitor the port(s) and
static trunk(s) available on the switch or one VLAN.
N o t e Individual ports and static trunks can be monitored at the same time. However,
if you configure the switch to monitor a VLAN, all other interfaces are removed
from monitoring. Also, you can configure only one VLAN at a time for moni­
toring.
Elements in the monitor list can include port numbers and static trunk names
at the same time.
For example, with a port such as port A6 configured as the monitoring (mirror)
port, you would use either of the following commands to select these inter­
faces for monitoring:
• A1 through A3, and A5
• Trunks 1 and 2
