Disable and enable LLDP TLVs on management ports
By default, management ports advertise all LLDP TLVs except VLAN name TLV. You can disable the LLDP TLV advertisement
on management ports using the following commands:
● Disable LLDP TLVs in INTERFACE mode.
no lldp tlv-select basic-tlv {port-description | system-name | system-description |
system-capabilities | management-address}
no lldp tlv-select dot1tlv {port-vlan-id | vlan-name}
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
To advertise LLDP TLVs from the management ports, use the following commands:
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 management address TLVs in a VLT domain
The management address TLV advertises the IP address of the management interface to adjacent LAN devices. The system
advertises this information in the management address TLV of all the physical ports. In a VLT domain, peer VLT devices transmit
the IP address of their local management interface in the management address TLV.
To integrate with solutions such as the Cisco Application Centric Infrastructure (ACI), OS10 switches that are VLT peers, must
advertise one common IP address in the management address TLV of the LLDPDU. This common IP address is also known as a
virtual IP address, so that the VLT peers appear as a single switch to the Cisco ACI.
Configure OS10 switches that are part of a VLT pair to select a single IPv4 or IPv6 address as the virtual IP address. When
you enable this feature, OS10 selects the lowest IP address per subnet that is configured on the management interface or
management VLAN as the virtual IP address. LLDP advertises this virtual IP address in the management address TLV.
NOTE: This feature works only on devices that are part of a VLT domain.
Advertise virtual management IP address in management address TLV
You can enable the system to select a single IP address in a VLT pair, using the lldp management-addr-tlv {ipv4
| ipv6} virtual-ip command globally or on a specific interface. LLDP advertises the elected virtual IP address in the
management address TLV.
To enable the service to send the virtual management IP address in the management address TLV:
● Enable the service to send the virtual IP address in the management address TLV using lldp management-addr-tlv
{ipv4 | ipv6} virtual-ip in CONFIGURATION mode.
When enabled in CONFIGURATION mode, the configuration applies globally and the system advertises the elected IP address
in the management address TLV.
● Enable the service to send the virtual IP address in the management address TLV using lldp management-addr-tlv
{ipv4 | ipv6} virtual-ip in INTERFACE mode.
When enabled in INTERFACE mode, the configuration applies to the specific interface and the system advertises the elected
IP address in the management address TLV.
OS10(config)#lldp management-addr-tlv ipv4 virtual-ip
OS10(config-if-eth1/1/6)#lldp management-addr-tlv ipv4 virtual-ip
OS10(config-if-eth1/1/6)#lldp management-addr-tlv ipv6 virtual-ip
