Configures the LLDP (Link Layer Discovery Protocol) port to advertise or not advertise MED capabilities. This TLV must be enabled before any of the other MED TLVs can be enabled. Also, this TLV must be set to no-advertise after all other MED TLVs are set to no-advertise.
| all | Specifies all ports on the switch. |
| port_list | Specifies one or more ports or slots and ports. |
| advertise | Specifies to send the information to neighbors. |
| no-advertise | Specifies not to send the information to neighbors. |
No advertise.
This command enables the LLDP media endpoint discovery (MED) capabilities TLV, which allows LLDP-MED network connectivity devices to definitively determine that particular endpoints support LLDP MED, and if so, to discover which LLDP MED TLVs the particular endpoint devices are capable of supporting and to which specific device class the device belongs to.
This TLV must be enabled before any of the other MED TLVs can be enabled; and this TLV must be set to no-advertise after all other MED TLVs are set to no-advertise.
As with all the LLDP MED TLVs, the switch sends this TLV only after it detects a MED-capable device on the port. The switch does not automatically send this TLV after it is enabled; the switch must first detect a MED-capable device on the port.
Note
Network connectivity devices wait to detect LLDP MED TLVs from endpoints before they send out LLDP MED TLVs; so L2 network connectivity devices do not exchange LLDP MED messages.
The supported LLDP MED TLVs—For Extreme Networks devices, these are capabilities, network policy, location, and extended power (extended power only advertised only on PoE (Power over Ethernet)-capable ports).
The MED device type—For Extreme Networks devices, this is advertised as a network connectivity device (set to 4).
The following command configures all ports to advertise MED capabilities to neighbors:
configure lldp ports all advertise vendor-specific med capabilities
This command was first available in ExtremeXOS 11.5.
This command is available on the Summit X450-G2, X460-G2, X670-G2, X770, and ExtremeSwitching X440-G2, X620, X690, X870 series switches.
