CDP was created by Cisco in 1994. [2] Its original intent was to make it easier to find other devices on a network. [1] CDP may be used between Cisco routers, switches and other network equipment to advertise their software version, capabilities and IP address. [3] The two versions of CDP are CDPv1 and CDPv2:
A VTP domain for a network is a set of all contiguously trunked switches with the matching VTP settings (domain name, password and VTP version). All switches in the same VTP domain share their VLAN information with each other, and a switch can participate in only one VTP management domain. Switches in different domains do not share VTP information.
Cisco Discovery Protocol (CDP) is a proprietary data link layer protocol developed by Cisco Systems in 1994 [1] by Keith McCloghrie and Dino Farinacci. It is used to share information about other directly connected Cisco equipment, such as the operating system version and IP address .
Most Cisco products that run IOS also have one or more "feature sets" or "packages", typically eight packages for Cisco routers and five packages for Cisco network switches. For example, Cisco IOS releases meant for use on Catalyst switches are available as "standard" versions (providing only basic IP routing), "enhanced" versions, which ...
PPP can assign IP addresses to these virtual interfaces, and these IP addresses can be used, for example, to route between the networks on both sides of the tunnel. IPsec in tunneling mode does not create virtual physical interfaces at the end of the tunnel, since the tunnel is handled directly by the TCP/IP stack.
Other devices, such as Cisco Catalyst switches, support MAC filtering on a port-by-port basis. This is referred to as port security . Port security may be configured statically with a list, dynamically based on the first given number of addresses detected, or a combination of these two methods.

An example of router on a stick usage is found in Call Manager Express installation, when the Voice over IP network and Cisco IP phone devices have a need to split. [3] Enterprise networks implement this method of separating servers to prevent all users from ‘having equal access privilege to resources’.
