Abstract: In an example of a method for implementing three-layer communication of a management packet, a controlling bridge creates a first virtual management ethernet (VME) port with a first MAMA address, and allocates a first IP address to the first VME port. A port extender creates a second VME port with a second MAC address, and requests an IP address of the second VME port from the controlling bridge. The controlling bridge allocates a second IP address to the second VME port, and notifies the port extender of the second IP address and the first IP address; acquires the second MAC address of the second VME port to send receive a management packet to from the second VME port through three-layer communication.

If the unique identifier of the PE device does not exist in the array table, an idle first aggregation group identifier is selected, a first aggregation group corresponding to the first aggregation group identifier is created, the first port is added to the first aggregation group, and a correspondence between the first aggregation group identifier and the unique identifier of the PE device is recorded in the array table.

Abstract: A method for accessing a forwarding entry and a network device are provided. In an example, a cache receives, from a forwarding component, an entry reading command which carries a storage address in a storage of a first forwarding entry to be read. The cache locally searches for a first Hash bucket in a valid state according to the storage address of the first forwarding entry, the first Hash bucket containing a storage address identical to that of the first forwarding entry. If the first Hash bucket is found, the cache transmits, to the forwarding component, the first forwarding entry cached in cache space corresponding to the first Hash bucket. If not found, the cache reads the first forwarding entry from the storage and transmits the first forwarding entry to the forwarding component when the first Hash bucket is not found.
