Disable and re-enable LLDP on management ports
By default, LLDP is enabled on management ports. You can disable or enable the following LLDP configurations on management
ports.
1. Disable the LLDPDU transmit or receive.
no lldp transmit
no lldp receive
2. Disable LLDP TLVs.
no lldp tlv-select basic-tlv {port-description | system-name | system-description |
system-capabilities | management-address}
no lldp tlv-select dot1tlv port-vlan-id
Disable LLDP transmit or receive
OS10(config)# interface mgmt 1/1/1
OS10(conf-if-ma-1/1/1)# no lldp transmit
OS10(conf-if-ma-1/1/1)# no lldp receive
Enable LLDP transmit or receive
OS10(config)# interface mgmt 1/1/1
OS10(conf-if-ma-1/1/1)# lldp transmit
OS10(conf-if-ma-1/1/1)# lldp receive
Disable LLDP TLVs
OS10(config)# interface mgmt 1/1/1
OS10(conf-if-ma-1/1/1)# no lldp tlv-select basic-tlv system-name system-description
OS10(conf-if-ma-1/1/1)# no lldp tlv-select dot1tlv port-vlan-id
Enable LLDP TLVs
OS10(config)# interface mgmt 1/1/1
OS10(conf-if-ma-1/1/1)# lldp tlv-select basic-tlv system-name system-description
OS10(conf-if-ma-1/1/1)# lldp tlv-select dot1tlv port-vlan-id
Advertise TLVs
Configure the system to advertise TLVs from all interfaces or specific interfaces. If you configure an interface, only the
interface sends LLDPDUs with the specified TLVs.
1. Enable basic TLVs attributes to transmit and receive LLDP packets in INTERFACE mode.
lldp tlv-select basic-tlv {port-description | system-name | system-description |
system-capabilities | management-address}
2. Enable dot3 TLVs to transmit and receive LLDP packets in INTERFACE mode.
lldp tlv-select dot3tlv {macphy-config | max-framesize}
3. Enable dot1 TLVs to transmit and receive LLDP packets in INTERFACE mode.
lldp tlv-select dot1tlv { port-vlan-id | link-aggregation}
