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.
- SNMP 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.
This feature is supported on all ExtremeXOS platforms.
