LABEL DESCRIPTION
Basic TLV These are the Basic TLV flags
Port ID TLV The port ID TLV identifies the specific port that transmitted the LLDP frame.
• Port ID Subtype: This shows how the port is identified.
• Port ID: This is the ID of the port.
Port T his displays the local port description.
Description TLV
Dot1 TLV
Port VLAN ID This displays the VLAN ID sent by the IEEE 802.1 Port VLAN ID TLV.
TLV
Port-Protocol This displays the IEEE 802.1 Port Protocol VLAN ID TLVs, which indicates whether the
VLAN ID TLV
VLAN is enabled and supported.
Dot3 TLV
MAC PHY The MAC/PHY Configuration/Status TLV advertises the bit-rate and duplex capability of
Configuration &
the sending 802.3 node. It also advertises the current duplex and bit-rating of the
Status TLV
sending node. Lastly, it advertises whether these setting were the result of auto-
negotiation during link initiation or manual override.
• AN Supported - Displays if the port supports or does not support auto-negotiation.
• AN Enabled - The current auto-negotiation status of the port.
• AN Advertised Capability - The auto-negotiation capabilities of the port.
• Oper MAU Type - The current Medium Attachment Unit (MAU) type of the port.
Link The Link Aggregation TLV indicates whether the link is capable of being aggregated,
Aggregation
whether the link is currently in an aggregation, and if in an aggregation, the port
TLV
identification of the aggregation.
• Aggregation Capability — The current aggregation capability of the port.
• Aggregation Status — The current aggregation status of the port.
• Aggregation Port ID — The aggregation ID of the current port.
Max Frame This displays the maximum supported frame size in octets.
Size TLV
MED TLV LLDP Media Endpoint Discovery (MED) is an extension of LLDP that provides additional
capabilities to support media endpoint devices. MED enables advertisement and
discovery of network policies, device location discovery to allow creation of location
databases, and information for troubleshooting.
Capabilities This field displays which LLDP-MED TLV are capable to transmit on the Switch.
