CDP
Cisco Discovery Protocol (CDP) is a device discovery protocol that runs on all
Cisco manufactured equipment. Each CDP enabled device sends periodic
messages to a multicast address and also listens to the periodic messages sent
by others in order to learn about neighboring devices and determine the status of
these devices. This page provides the configuration options to control CDP.
NOTE Enabling CDP is not recommended on the Dedicated WAN port and the Optional
ports because they are connected to insecure networks.
STEP 1 Click Network Management > CDP.
The CDP window opens.
STEP 2 Enter the following information:
• CDP: Choose one of the following options:
- Enable All: Enable CDP on all port supported by the Device.
- Disable All: Disable CDP
- Per Port: Configure CDP on selective ports, displayed in the port
information table.
• CDP Timer: This is the time interval between any successive CDP packets
sent by the router.
• CDP Hold Timer: The hold timer is the amount of time the information sent
in the CDP packet should be cached by the device which receives the CDP
packet, after which the information is expires.
STEP 3 Click Apply to save your settings.
SNMP
Simple Network Management Protocol (SNMP) lets you monitor and manage your
router from an SNMP manager. SNMP provides a remote means to monitor and
control network devices, and to manage configurations, statistics collection,
performance, and security. The router supports the SNMPv2c protocol version
and can send traps to a specified community.
