Cisco switch is not able to identify a neighbor, even though lldp is enabled. -- Run the command "show lldp neighbor" so you can see the neighbor information on the switch. -- The Arista switch is able to decode the malformed PDU's but tcpdump pcap shows a malformed packet.
Cisco switch does not display the lldp neighbor information. This information is useful to see connected devices and the port information for the connection. If captured using tcpdump, the malformed packet can be seen on the Arista switch.
-- Cisco switch is connected to hardware. -- LLDPDU's are tracked on tcpdump on an Arista switch instead of just checking "show neighbor information."
Configure only mandatory threshold value limits(chassis-id, port-id and ttl) for lldp. Config#lldp interfaces interface 1.0 config name 1.0 tlvmap chassis-id,port-id,ttl.
