CDP is enabled by default on all Cisco routers, switches and servers. The protocol can be disabled across a network; however, if it is disabled on an interface and the encapsulation is changed, it will be re-enabled on that interface. [5] [6] The protocol is most often used to aid network administrators by finding and discovering devices easier ...
Exceptions include some Cisco Catalyst switches, which run IOS XE, and Cisco ASR routers, which run either IOS XE or IOS XR; both are Linux-based operating systems. For data center environments, Cisco Nexus switches and Cisco MDS switches (Fibre Channel) both run Cisco NX-OS, also a Linux-based operating system.
IOS XE is a release train of Cisco Systems' widely deployed Internetworking Operating System (IOS), introduced with the ASR 1000 series. [2]It is built on Linux [3] [4] and provides a distributed software architecture that moves many operating system responsibilities out of the IOS process [5] [6] and has a copy of IOS running as a separate process.

TACACS and XTACACS both allow a remote access server to communicate with an authentication server in order to determine if the user has access to the network. TACACS Plus (TACACS+) is a protocol developed by Cisco and released as an open standard beginning in 1993.
If the resulting hashes match, then the user is deemed to be authenticated. If the hashes do not match, then the user's authentication attempt is rejected.
