Chapter 37 Link Layer Discovery Protocol (LLDP) The following table describes the labels in this screen. Table 169 Advanced Application > LLDP > LLDP Local Status > LLDP Local Port Status Detail LABEL DESCRIPTION Basic TLV Port ID TLV These are the Basic TLV flags The port ID TLV identifies the specific port that transmitted the LLDP frame. Port Description TLV Dot1 TLV Port VLAN ID TLV Port-Protocol VLAN ID TLV Dot3 TLV MAC PHY Configuration & Status TLV • Port ID Subtype: This shows how the port is identified. • Port ID: This is the ID of the port. In stacking mode, the first number represents the slot and the second the port number. This displays the local port description. This displays the VLAN ID sent by the IEEE 802.1 Port VLAN ID TLV. This displays the IEEE 802.1 Port Protocol VLAN ID TLVs, which indicates whether the VLAN is enabled and supported. 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. Link Aggregation TLV • 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. 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. Max Frame Size TLV MED TLV Capabilities TLV • Aggregation Port ID - The aggregation ID of the current port. This displays the maximum supported frame size in octets. 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. This field displays which LLDP-MED TLV are capable to transmit on the Switch. Device Type TLV • Network Policy • Location • Extend Power via MDI PSE • Extend Power via MDI PD • Inventory Management This is the LLDP-MED device class. The Zyxel Switch device type is: • Network Connectivity XS3800-28 User's Guide 378
