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.

Abstract: When needing to forward a packet from a switch line card to a programmable line card, the switch line card may encapsulate a pseudo-Layer 2 header for the packet based on uplink forwarding process of the switch line card. The pseudo-Layer 2 header may carry an adjacency table index and an egress interface table index which is used by the programmable line card. Correspondingly, the programmable line card may obtain the adjacency table index and the egress interface table index from the pseudo-Layer 2 header of the packet, and then may re-encapsulate a real Layer 2 header for the packet based on downlink forwarding process of the programmable line card, and transmit the packet through a corresponding egress interface.
