Glossary
Shared port adapter interface processor. A SIP is a platform-specific carrier card that inserts into a
SIP
router slot like a line card. A SIP can hold one or more SPAs in its subslots, depending on the SIP type.
The SPA provides the network interface. The SIP provides the connection between the route processor
(RP1) and the SPA.
The sub-package responsible for providing the SPA drivers, the SPA FPGA, and any other software
SIPBase
related to the SPAs.
sub-package
The sub-package responsible for controlling the SIP operating system and control processes.
SIPSPA
sub-package
Small form-factor pluggable optical transceiver. A type of fiber optic receptacle device that mounts
SFP
flush with the front panel to provide network connectivity.
Describes the dimension of a SPA that occupies a single SIP subslot or half of the SIP.
Single height
A single software file on the Cisco ASR 1000 Series Router. Cisco IOS XE software is released using
Sub-package
consolidated packages, and these consolidated packages contain multiple sub-packages. Each
sub-package has a defined responsibility for running a Cisco ASR 1000 Series Router.
Shared Port Adapter. A SPA is a modular, platform-independent shared port adapter that inserts into a
SPA
subslot of a compatible SIP carrier card to provide network connectivity and increased interface port
density. The SPA provides the interface between the network and the SIP.
Solid state disk drive.
SSD
Stateful switchover. Action of transitioning from one operational unit to another without loss of
SSO
checkpointed state.
Shielded twisted-pair
STP
Secondary slot on a SIP where a SPA is installed.
Subslot
A single transmit and receive serial pair running initially at 1.25Gbits giving a payload of 1.0Gbits,
Serial Link
with future scalability to 3.125 Gbits giving a payload of 2.5 Gbits.

T
A configuration option that can be used to provide more granularity related to users accessing a router.
Transport map
Transport maps can be applied to console ports or to any users accessing a router using telnet or SSH.
