lldpad and port ID to show interface name

Postby mdb9676 » 2017/09/06 04:02:22

We have a BGP setup where the servers have both 10g interfaces connected to different switches. On the switch end we run the following and see this...

swtor403#sh lldp ne eth35
Last table change time : 0:03:43 ago
Number of table inserts : 636
Number of table deletes : 596
Number of table drops : 0
Number of table age-outs : 6

Port Neighbor Device ID Neighbor Port ID TTL
Et35 tbvertui01sh1 48df.3706.bda9 120
swtor403#

I am trying to find the setting on the lldpad on the server end that will tell the switches the interface name " ie eno49/50" for the Neighbor Port ID, instead of the MAC address.

I have run this command on the server and still not getting it to change.

lldptool set-lldp -i eno49 adminStatus=rxtx  ;
      lldptool -T -i eno49 -V  sysName enableTx=yes;
      lldptool -T -i eno49 -V  portDesc enableTx=yes ;
      lldptool -T -i eno49 -V  sysDesc enableTx=yes;
      lldptool -T -i eno49 -V sysCap enableTx=yes;
      lldptool -T -i eno49 -V mngAddr enableTx=yes;

Some label applied to a networking device is meaningless, in Ethernet (or IPv4), MAC address has meaning, arbitrary labels not.
You can supply the label as data thought. What are you *really* trying to achieve?

Our Network team was hoping to have the interface "Name" instead of the MAC address listed, so it would allow them to know if it is "ens49" or "ens50" , when troubleshooting network issues.

ie ...
