LLDP Discarded Packets
Hi, I am wondering if LLDP is not working on 2,5 Gbit Interfaces running on 2,5 Gbit on SG3210X-M2.
The LLDP packets seem to be discarded in controller mode:
two-gigabitEthernet 1/0/7:
Tx-Pkt: 76
Rx-Pkt: 69
Discard-Pkt: 0
Error-Pkt: 0
Aged-Neighbor: 0
Discard-TLV: 0
Unknown-TLV: 0
two-gigabitEthernet 1/0/8:
Tx-Pkt: 76
Rx-Pkt: 71
Discard-Pkt: 71
Error-Pkt: 0
Aged-Neighbor: 0
Discard-TLV: 0
Unknown-TLV: 0
ten-gigabitEthernet 1/0/9:
Tx-Pkt: 74
Rx-Pkt: 72
Discard-Pkt: 0
Error-Pkt: 0
Aged-Neighbor: 0
Discard-TLV: 0
Unknown-TLV: 0
ten-gigabitEthernet 1/0/10:
Tx-Pkt: 76
Rx-Pkt: 70
Discard-Pkt: 0
Error-Pkt: 0
Aged-Neighbor: 0
Discard-TLV: 0
Unknown-TLV: 0
two-gigabitEthernet 1/0/7 is in 1 Gbit Mode and fine processing the packages.
All ports are using the same profile with lldp enabled.
@MatthiasL22 for me it is working between on 2.5Gbps ports on a SG2210XMP-M2 connected to EAP772 and a PC - all running at 2.5Gbps. However, it is failing between SG2210XMP-M2 switch and ER7412-M2 gateway (port 1/0/1 below), even though both have LLDP enabled. I'd love to know why too. (This is all controller mode.)
For you port(s) where LLDP is not working, what is it connected to?
@MatthiasL22 if you run it in the foreground with debug, you might be able to see what it is sending to the switch. Could be something Omada can't parse.
lldpd -dddd
My issue even stranger, as LLDP is not even working between two Omada devices that support LLDP and have it enabled.
I checked:
- ER7412-M2 <-> SG2210XMP-M2
- ER7412-M2 <-> SG2008P
LLDP is working fine in the switches, but not working with gateway, all discarded.
ER7412-M2 <-> SG2210XMP-M2
ER7412-M2 <-> SG2008P
The ER7412-M2 has an option in controller to enable LLDP
But the CLI doesn't seem to have the 'lldp' command? It would be bizarre for TP-Link gateway not to be compatible with TP-Link's own switches! 😬
