Link Layer Discovery Protocol (802.1ab)

IEEE 802.1 organizationally-specific TLVs

The optional IEEE 802.1 organizationally-specifc TLVs are:
• Port VLAN ID TLV contains the local port PVID.
• Port And Protocol VLAN ID TLV contains the VLAN IDs of the port and protocol VLANs
that contain the local port.
• VLAN Name TLV contains the VLAN names of the VLANs that contain the local port.
• Protocol Identity TLV advertises the protocol supported. The following values are used
for supported protocols on the 4500 Series:
- Stp protocol {0x00,0x26,0x42,0x42,0x03, 0x00, 0x00, 0x00}
- Rstp protocol string {0x00,0x27,0x42,0x42,0x03, 0x00, 0x00, 0x02}
- Mstp protocol string {0x00,0x69,0x42,0x42,0x03, 0x00, 0x00, 0x03}
- Eap protocol string {0x88, 0x8E, 0x01}
- Lldp protocol string {0x88, 0xCC}

IEEE 802.3 organizationally-specific TLVs

The optional IEEE 802.3 organizationally-specifc TLVs are:
• MAC/PHY Configuration/Status TLV indicates the autonegotiation capability and the
speed and duplex status of IEEE 802.3 MAC/PHYs.
• Power-Via-MDI TLV indicates the capabilities and current status of IEEE 802.3 PMDs
that either require or can provide power over twisted-pair copper links.
• Link Aggregation TLV indicates the current link aggregation status of IEEE 802.3
MACs.
• Maximum Frame Size TLV indicates the maximum supported 802.3 frame size.

Organizationally-specific TLVs for MED devices

The optional organizationally-specific TLVs for use by Media Endpoint Devices (MED) and
MED network connectivity devices are:
• Capabilities TLV enables a network element to advertise the LLDP-MED TLVs it is
capable of supporting.
• Network Policy Discovery TLV is a fixed length TLV that enables both network
connectivity devices and endpoints to advertise VLAN type, VLAN identifier (VID), and
Layer 2 and Layer 3 priorities associated with a specific set of applications on a port. In
