LLDP-MED operational support

The switches offer two configurable TLVs supporting MED-specific capabilities:

  • medTlvEnable (for per-port enabling or disabling of LLDP-MED operation)

  • medPortLocation (for configuring per-port location or emergency call data)


LLDP-MED operation also requires the port speed and duplex TLV (dot3TlvEnable), which is enabled in the default configuration.

Topology change notifications provide one method for monitoring system activity. However, because SNMP normally employs UDP, which does not guarantee datagram delivery, topology change notification should not be relied upon as the sole method for monitoring critical endpoint device connectivity.
