Enabling IEEE 802.3 Organizationally Specific TLVs

This section describes how to enable IEEE 802.3 organizationally-specific TLVs, whose transmission status is set to Disabled by default. They are as follows:

MAC-PHY Configuration/Status
Link Aggregation
Max Frame Size

At Switch A and Switch B:

Note:

Configure the LLDP module status as enabled. Refer to section “Enabling LLDP” for details.

Enable IEEE 802.3 Organizationally-specific TLVs by executing the following commands.

Type the following:

Enter the Global Configuration Mode.

iS5comm# configure terminal

Enable IEEE 802.3 organizationally-specific TLVs on port P1.

iS5comm(config)# interface gigabitethernet 0/1

iS5comm(config-if)# lldp tlv-select dot3tlv link-aggregation

iS5comm(config-if)# lldp tlv-select dot3tlv macphy-config

iS5comm(config-if)# lldp tlv-select dot3tlv max-framesize

iS5comm(config-vlan)# end

At Switch A: view the local system information by executing the following command.

Perform the following:

iS5comm# show lldp local gigabitethernet 0/1
