Configuring CDP
Use the Cisco IOS CLI and Cisco Discovery Protocol (CDP) to enable CDP for the switch, set global
CDP parameters, and display information about neighboring Cisco devices.
CDP enables the Cluster Management Suite (CMS) to display a graphical view of the network. For
example, the switch uses CDP to find cluster candidates and to maintain information about cluster
members and other devices up to three cluster-enabled devices away from the command switch.
You can configure CDP to discover switches running the CMS up to seven devices away from the
command switch. Devices that do not run clustering software display as edge devices, and CDP cannot
discover any device connected to them.
Note
Creating and maintaining switch clusters is based on the regular exchange of CDP messages. Disabling
CDP can interrupt cluster discovery. For more information about the role that CDP plays in clustering,

Catalyst 2950 Switch Traps
Generate traps whenever the switch configuration changes.
Generate the supported SNMP traps.
Generate traps when the switch starts a management console CLI session.
Generate a trap for each VLAN Membership Policy Server (VMPS) change.
Generate a trap for each VLAN Trunking Protocol (VTP) change.
Generate the cluster traps.
Generate the ENTITY_MIB traps.
Generate the SNMP HSRP traps.
Enable the SNMP Response Time Reporter Traps.
Generate a trap when a MAC address is added or removed from any interface.
