LABEL DESC RIPTIO N
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.
• Po rt ID Sub type : This shows how the port is identified.
• Po rt ID: This is the ID of the port.
Port Description
TLV
This displays the local port description.
Dot1 TLV
Port VLAN ID
TLV
This displays the VLAN ID sent by the IEEE 802.1 Port VLAN ID TLV.
Port Protocol
VLAN ID TLV
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 Suppo rte d – Displays if the port supports or does not support auto-negotiation.
• AN Ena ble d – The current auto-negotiation status of the port.
• AN Adve rtise d C a pa b ility – The auto-negotiation capabilities of the port.
• O pe r 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.
• Ag g re g a tio n C a pa b ility – The current aggregation capability of the port.
• Ag g re g a tio n Sta tus – The current aggregation status of the port.
• Ag g re g a tio n Po rt 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.
