  Extracted from Book #2, page 359:

  "... the following list details some of the more common actions that a networking device does that fit into the data plane:

  -

  De-encapsulating and re-encapsulating a packet in a data-link frame (routers, layer 3 switches).

  -

  Adding or removing an 802.1Q trunking header (routers and switches).

  -

  Matching an ethernet frame's destination MAC address to the MAC address table (layer 2 switches).

  -

  Matching an IP packet's destination IP address to the IP routing table (routers, layer 3 switches).

  -

  Encrypting the data and adding a new IP header (for VPN processing).

  -

  Changing the source or destination IP address (for NAT) processing).

  -Discarding a message due to a filter (ACLs, port security).

  All the items in the list make up the data plane, because the data plane includes all actions done per message."
