On-Demand Routing ("ODR") is an enhancement to Cisco Discovery Protocol (CDP), a protocol used to discover other Cisco devices on either broadcast or non-broadcast media. With the help of CDP, it is possible to find the device type, the IP address, the Cisco IOS version running on the neighbor Cisco device, the capabilities of the neighbor device, and so on.
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 .
(config)# no cdp run. To enable it on certain interface(s): (config-if)# cdp enable. To disable it on certain interface(s): (config-if)# no cdp enable. In a table, to display whether or not a device has established a connection between another device or devices: (device name)# show cdp neighbors
The Link Layer Discovery Protocol (LLDP) is a vendor-neutral link layer protocol used by network devices for advertising their identity, capabilities, and neighbors on a local area network based on IEEE 802 technology, principally wired Ethernet. [1]

Security event manager : Real-time monitoring, correlation of events, notifications and console views. Security information and event management (SIEM): Combines SIM and SEM and provides real-time analysis of security alerts generated by network hardware and applications. [5] [citation needed]
Packet Tracer is commonly used by NetAcad students, since it is available to download after creating a free account. [10] However, due to functional limitations, it is intended by Cisco to be used only as a learning aid, not a replacement for Cisco routers and switches . [ 9 ]
TACACS is defined in RFC 1492, and uses (either TCP or UDP) port 49 by default.TACACS allows a client to accept a username and password and send a query to a TACACS authentication server, sometimes called a TACACS daemon.
