Catalyst 4224 Access Gateway Switch Software Configuration Guide
3-16
A detection mechanism on the Catalyst 4224 determines whether it is connected
to a Cisco 7960 IP Phone. If the switch senses that there is no power on the circuit,
the switch supplies the power. If there is power on the circuit, the switch does not
supply it.
You can configure the switch to never supply power to the Cisco 7960 IP Phone
and to disable the detection mechanism.
Beginning in privileged EXEC mode, follow these steps to configure a port to
never supply power to Cisco 7960 IP Phones:
Task
Enter global configuration mode.
Enter interface configuration mode,
and enter the port to be configured.
Permanently disable inline power on
the port.
Return to privileged EXEC mode.
Verify the change by displaying the
setting as configured.
Entering the show power inline [interface-type number] command in privileged
EXEC mode displays the power allocated to the IP phone by the Catalyst 4224.
To display the maximum power requested by the IP phone, enter the show cdp
neighbors [interface-type number] detail command in privileged EXEC mode.
You can monitor traffic on a given port by forwarding incoming and outgoing
traffic on the port to another port in the same VLAN. A Switch Port Analyzer
(SPAN) port cannot monitor ports in a different VLAN, and a SPAN port must be
a static-access port. Any number of ports can be defined as SPAN ports, and any
combination of ports can be monitored. SPAN is supported for up to two sessions.
