VLANs and VLAN Trunk Protocol

For information on the concept of VLANs and VLAN Trunk Protocol (VTP), see VLANs.

Layer 2 Ethernet Switching

For information on the concept of Layer 2 Ethernet Switching, see Layer 2 Ethernet Switching.

802.1x Authentication

For information on the concept of 802.1x Authentication, see 802.1x Authentication.

Spanning Tree Protocol

For information on the concept of Spanning Tree Protocol, see Using the Spanning Tree Protocol with the Cisco EtherSwitch Network Module.

Cisco Discovery Protocol

Cisco Discovery Protocol (CDP) runs over Layer 2 (the data link layer) on all Cisco routers, bridges, access servers, and switches. CDP allows network management applications to discover Cisco devices that are neighbors of already known devices, in particular, neighbors running lower-layer, transparent protocols. With CDP, network management applications can learn the device type and the SNMP agent address of neighboring devices. This feature enables applications to send SNMP queries to neighboring devices.
