There are a number of reasons that this happening but lets start with the protocols in place
there is cdp, ciscodp and lldp
The standard is LLDP
To start LLDP on the C5 is set to Auto by default but it needs someone to talk to it via lldp( like a phone ir another switch
The easiest was to get the information is to start the conversation
What is usually do provide the basic's and then let the customer to decide if they want more than tge basic ip and say mac
so i suggest the following
set lldp port tx-tlv ?
this gives you a list of options ( in the lab i select all but you may want
I provided a list below ( please note my image may not be up to date)
but you are looking for mgmt-addr, so your command would be something like this
set lldp port tx-tlv mgmt-addr ( port # or for all ports *.*.* )
please note that if the other side of the link does not support the feature then you will get nothing
-There is another bonus for you from me
afte setting this up on your switch, try this command (for local and remote -information) you will like the feedback
show lldp port remote-info ge.x.x
going back to our question, the list below should help you
(su)->set lldp port tx-tlv ?
