N
Node
A card installed and running in an Cisco CRS-1 Series routing system. In the Cisco 12000 series
Internet Router, nodes are identified by slot number (for example, node 1).
R

Network layer device that uses one or more routing metrics to determine the optimal path along which
network traffic should be forwarded. Routers forward packets from one network to another based on
network layer information.
Running
Configuration
The router configuration currently in effect. Although, the user can save multiple versions of the router
configuration for future reference, there is only one copy of the running configuration in the router at
any given time. An explicit commit operation must be performed to make changes to or update the
running configuration on the Cisco CRS-1 Series router.
S
Software
Configuration
A list of packages activated for a particular node. A software configuration consists of a boot package
and additional feature packages.
SSH
Secure Shell
SSL
Secure Socket Layer
Startup
Configuration
The router configuration designated to be applied on next router startup.
Switchover
A switch between the active and standby cards; the old active card may be dead prior to switchover
(death of the active card is one of the causes for the switchover). Also known as failover.
System Reload
Reload of an Cisco CRS-1 Series router node.
System Restart
Soft reset of an Cisco CRS-1 Series router node. This involves restarting all the processes running on
that node.
