I am working on mapping layer 2 devices by parsing the output from "show LLDP neighbors detail". The network contains only Cisco devices. To properly create the maps, I require the following fields:
- Local Intf (source interface)
- Chassis ID (target mac address)
- Port ID (abbreviated name and identifying number of port)
- Port Description (information regarding the connection)
However, on some devices, the local interface is not advertised, and, because the architecture contains LAGs, there isn't a reliable way to guess based on the target chassis ID and port ID. Speaking of port ID, although usually reported in a manner similar to "gi1/0/1" or "fa01", sometimes the port ID is reported in an odd format, such as port-002-00000. This can occur even if the same port ID was properly reported on the local interface of the source device.
Is there a way to force "show lldp neighbors detail" to display the local interface and format port IDs as "[a-z]{2}\d+.*"?
Thanks for reading
