The following table describes the labels in this screen.
Table 78   PORT > LLDP > LLDP > LLDP Local Status > LLDP Local Port Status Detail
LABEL DESCRIPTION
Local Port This displays the number of the Switch’s port.
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 Description 
TLV
Port Description – This displays the local port description.
Dot1 TLV
Port VLAN ID 
TLV
Port VLAN ID – This displays the VLAN ID sent by the IEEE 802.1 Port VLAN ID TLV.
Port-Protocol 
VLAN ID TLV
Port-Protocol VLAN ID – This displays the IEEE 802.1 Port Protocol VLAN ID TLVs, which indicates 
whether the VLAN is enabled and supported.
Dot3 TLV
MAC PHY 
Configuration & 
Status TLV
The MAC/PHY Configuration/Status TLV advertises the bit-rate and duplex capability of the 
sending 802.3 node. It also advertises the current duplex and bit-rating of the 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 
Aggregation 
TLV
The Link Aggregation TLV indicates whether the link is capable of being aggregated, 
whether the link is currently in an aggregation, and if in an aggregation, the port 
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 Size 
TLV
This displays the maximum supported frame size in octets.
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 TLV This field displays which LLDP-MED TLV are capable to transmit on the Switch.
• Network Policy
• Location
• Extend Power via MDI PSE
• Extend Power via MDI PD
• Inventory Management
