| Description | Specifies whether or not the Source Address Control feature is
enabled for the port. This feature provides the ability to
control which device's specific MAC address is allowed access
to the network. If the management entity specified an address
via ciscoRptrPortAllowedSrcAddr, only the device with the
configured MAC address is allowed access to the network. If
the management entity does not specified an address, the
allowed source address is learned from the last source address
if valid; otherwise, the allowed source address is learned from
the MAC address of the first valid packet detected on the port.
When another MAC address other than the allowed source address
is detected on the port, the port is partitioned.
WARNING: Configuring Source Address Control feature on the
port which is used for management can cause the management
entity to lose access to the agent if the management's source
address does not match the allowed source address. |
