Logical Link Discovery Protocol
LOGICAL LINK DISCOVERY PROTOCOL
It is possible to activate the IEEE 802.1AB CHD Link Layer Discovery Protocol (LLDP) on each port,
and use it to recognize (and be recognized) by the adjacent nodes.
To do so, type:
set ethX lldp
Once the protocol has been activated, you can view the list of the adjacent nodes by using:
show lldp neighbors
that shows a screen like:

You can configure the Policy LLDP-MED extensions by specifying a possible VLAN reserved for voice
applications. The commands are:
set vlan add vid 35 interface eth2
set vlan eth2.35 ipaddr 10.10.35.1 netmask 255.255.0.0
set lldp intercace eth2 lldp-med-vid 35
set eth2 lldp on
