Users Guide

For example, LLDP timer transmit interval is set to 30 seconds and the holdtime-multiplier is set to 4, the TTL is 120 seconds
(30 x 4). The default TTL of 120 seconds. You can adjust the TTL value by changing the multiplier value of the holdtime.
1. Adjust the TTL value in CONFIGURATION mode.
lldp holdtime-multiplier
2. Return to the default multiplier value in CONFIGURATION mode.
no lldp holdtime-multiplier
OS10(config)# lldp holdtime-multiplier 2
View LLDP timers
OS10# show lldp timers
LLDP Timers:
Holdtime in seconds: 60
Reinit-time in seconds: 2
Transmit interval in seconds: 30
Configure LLDP to advertise TLVs
Configure the system to advertise TLVs from specific interfaces. If you configure the LLDP to advertise TLVs on an interface,
only the interface sends LLDPDUs with the specified TLVs.
By default, all LLDP TLVs except VLAN name TLV are advertised. To advertise VLAN name TLV, you can configure the system
to advertise the names of VLANs in LLDPDUs. For more information, see Advertise VLAN name TLVs.
1. Enable basic TLV 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 | vlan-name}
Advertise VLAN Name TLVs
You can configure the system to advertise the names of VLANs in LLDPDUs. Configure the VLAN names before you configure
the system to advertise VLAN names.
By default, this feature is disabled. After you enable this feature, the system starts sending LLDPDUs with the configured name
of the default VLAN. If the default VLAN does not have a configured name, the system does not send an LLDPDU with a VLAN
name TLV.
Transmit VLAN name of the default VLAN
1. Enter INTERFACE mode from CONFIGURATION mode.
interface ethernet 1/1/1
2. Enable the vlan-name option in INTERFACE mode.
lldp tlv-select dot1-tlv vlan-name
3. Enter INTERFACE VLAN mode from CONFIGURATION mode.
interface vlan 1
