OK after laboriously stepping through the MIB, I see Dell switches publish the identifier in LLDPPortID instead of LLDPPortDesc.  So I've modified my script accordingly.  Thanks for triggering me to go through the MIB properly.
Hello I have some 5548 switches and am trying to configure LLDP on them.  I already figured out that by default these switches announce nothing as LLDP information to their partners.  So I changed the configuration to include the LLDP parameters as follows (example on switch sa4-16): interface ethernet g24lldp optional-tlv port-desc sys-name sys-descexit I have a script that tells me what the LLDP neighbours are: $ mrrogers sa4-16 | grep g24g24 -> sa4-39 ge-0/0/5.0 sa4-39 is a Juniper EX2200.  When I run the same script against it, I see what the dell is publishing: $ mrrogers sa4-39 | grep 'sa4-16'ge-0/0/5.0 -> sa4-16.gridwayit.local Ethernet Interface I have tried the other optional-tlv parameters, and tried changing the port description as well -- how do I get the dell switch to announce what ethernet port it is seeing its LLDP neighbour through? (If you are interested at all, mrrogers is here).
