LLDP Between HP A5500-24G and PowerConnect 6248

Hi!

Im having trouble with lldp discovery on my HP A5500-24G switch. The switch is not accepting frames from a Dell PowerConnect 6248 switch. Its classifying the messages as error frames.

Heres the output of the dis lldp statistics int gi 1/0/24 command:

LLDP statistics information of port 24 [GigabitEthernet1/0/24]:
The number of LLDP frames transmitted : 290410
The number of LLDP frames received : 0
The number of LLDP frames discarded : 3014
The number of LLDP error frames : 3014
The number of LLDP TLVs discarded : 0
The number of LLDP TLVs unrecognized : 0
The number of LLDP neighbor information aged out : 0
The number of CDP frames transmitted : 0
The number of CDP frames received : 0
The number of CDP frames discarded : 0
The number of CDP error frames : 0

LLDP configuration on the Dell switch:

lldp transmit-tlv port-desc sys-name sys-desc sys-cap
lldp transmit-mgmt
no lldp med transmit-tlv capabilities
no lldp med transmit-tlv network-policy

Thank in advance!

Personally what I would try is I would get on the Dell and remove all LLDP options except TTL then test again.

If the error goes away, add the other options back in one by one. and see what happens.

Vince, thanks for your comment! But it was a matter of firmware update. Once the Dell switch got it's firmware updated, the HP switch began to see it through LLDP.
