ExtremeXOS Cisco Discovery Protocol

Network elements exchange various information with neighboring elements that ranges from the switch IP/Mac addresses, switch names, versions of software, etc. This information is maintained in an Information Base, and management applications use it to create a topology map and manage the entire network. Vendor-specific discovery protocols are used to learn about network neighbor elements and their capabilities, and to exchange this information. Cisco Discovery Protocol (CDP) is a Cisco^® proprietary protocol that runs between direct connected network entities (routers, switches, remote access devices, IP telephones) to provide information sharing capabilities. ExtremeXOS supports CDP, and is called EXOS-CDP.

Limitations

The ExtremeXOS support for CDP has the following limitations:

SNMP (Simple Network Management Protocol) for this feature is not supported.
You should use this feature mainly for the network-endpoint devices, but you can also use it in network-network devices that have CDP support.
When port access is controlled by net login, the port must be authorized before it receives CDP packets.

Platform Support

This feature is supported on all ExtremeXOS platforms.
