Glossary
The reassembly and resequencing application-specific integrated circuit (ASIC) that takes cells from
sponge
the switch fabric and converts them into packets. The packets are then queued up at the egress
(outgoing) path.
The segmentation application-specific integrated circuit (ASIC) located in the ingress (incoming) path
sprayer
of line cards that takes packets, segments them into cells and sends them to the fabric.
Spatial Reuse Protocol (another name for DPT which is a ring-based IP protocol). A Cisco-developed
SRP
MAC layer protocol to allow multiple access to a SONET ring. It uses destination stripping of unicast
packets to enable spatial reuse.
standby RP.
sRP
Secure Shell. A protocol that provides a secure remote connection to a router through a Transmission
SSH
Control Protocol (TCP) application.
secure socket layer. A secure socket between two entities with authentication.
SSL
Denotes an inactive card or process that waits to become active; standby cards or processes are also
standby
sometimes denoted as backup.
The router configuration designated to be applied on next router startup.
startup
configuration
subinterface
Virtual interfaces created on a hardware interface. These software-defined interfaces allow for
segregation of traffic into separate logical channels on a single hardware interface and allow for better
utilization of the available bandwidth on the physical interface.
Provides switch fabric functionality. The S2 SM is installed in the fabric chassis. The line card chassis
switch module
contains either the S1/S2/S3, the S1/S3, or the S1/S2/S3T, depending on the configuration of the
system.
A switch between the active and standby cards; the old active card may be dead prior to switchover
switchover
(death of the active card is one of the causes for the switchover). Also known as failover.
The hardware component that manages configuration and health of a chassis within the Cisco CRS-1
system controller
Series routing system. In the line card chassis, the SC is part of the RP module. In the fabric chassis,
the SC is a separate shelf controller module. In this document, SC could refer to either RP (line card
chassis) or SC (fabric chassis), unless explicitly mentioned as one or the other.
Reload of a Cisco CRS-1 Series router node.
system reload
Soft reset of a Cisco CRS-1 Series router node. This involves restarting all the processes running on
system restart
that node.
