Configuring support for port speed and duplex advertisements

Syntax

[no] lldp config <port-list> dot3TlvEnable macphy_config

For outbound advertisements, this TLV includes the (local) switch port's current speed and duplex

settings, the range of speed and duplex settings the port supports, and the method required for

reconfiguring the speed and duplex settings on the device (autonegotiation during link initialization,

or manual configuration.)

Using SNMP to compare local and remote information can help in locating configuration

mismatches.

(Default: Enabled)

NOTE: For LLDP operation, this TLV is optional. For LLDP-MED operation, this TLV is mandatory.
