Configure the LLDP Module Status

The LLDP module status is set to Disabled by default.

Enable LLDP in both switches.

SEFOS# configure terminal
SEFOS(config)# set lldp enable
SEFOS(config)# end

In switch 1, view the LLDP module status.
```
SEFOS# show lldp

Enabling LLDP (that is, configuring the LLDP module status as Enabled) initiates the transmission of LLDPDUs with the mandatory TLVs (chassis-ID TLV, port-ID TLV, time-to-live TLV, and end of LLDPDU TLV) on all ports that are operational (up).
