Setting CDP Mode

The Cisco SCE 8000 is usually installed as a bump-in-the-wire device, and therefore forwards packets
(including CDP packets) from one interface to the corresponding interface, whereas a typical Cisco
device never forwards CDP packets from one interface to another interface. Therefore, the Cisco SCE
8000 extends the enabled state with the following three CDP modes:
•
•
•
(See
different CDP modes.)
Caution In cascade topologies, both Cisco SCE 8000 platforms must be configured to the same CDP mode.
By default, the CDP mode is set to bypass.
To reset the CDP mode to the default mode (bypass) use the default cdp mode command.
To change the CDP mode, use the following command in global configuration mode.
From the SCE(config)# prompt, type:
Command
cdp mode (standard | monitor | bypass)
Enabling CDP on a Specific Traffic Interface
By default, CDP is enabled on all traffic interfaces (see
section on page
To disable CDP on a specific interface, use the no cdp enable command in the appropriate interface
configuration mode.
To reenable CDP on a specific interface after disabling it, use the following command in the appropriate
interface configuration mode. CDP must be enabled globally on the Cisco SCE 8000 platform (cdp run
command) in order to enable a specific interface.
From the SCE(config if)# prompt, type:
