Cisco Discovery Protocol (CDP)

CDP is media and protocol independent, and runs on all Cisco equipment over the Subnetwork Access Protocol (SNAP).

Creating a Network Map

• The show cdp neighbors [type number] [detail] command can be used to obtain the following:

Device ID — Address

Port ID — Capabilities

Version — Platform

IP network prefix

VTP management domain name (CDPv2 only)

Native VLAN (CDPv2 only)

Full/Half duplex (CDPv2)

Establishing Telnet Connections

• To initiate a Telnet session any of the following alternatives can be used:

Denver>connect parisDenver>paris Denver>131.108.100.152Denver>telnet paris

• A hostname table or access to DNS for Telnet must be present for a name to work. Otherwise, the IP address of the remote router must be entered.

• Telnet can be used to determine if a remote router can be accessed.

Configuration Register Values

The order in which the router looks for system bootstrap information depends on the boot field setting in the configuration register. The default configuration register setting can be changed with the global configuration mode command config-register. Use a hexadecimal number as the argument for this command.
