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
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 the 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
Shielded twisted-pair
STP
Secondary slot on a SIP where a SPA is installed.
Subslot
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.
A function on the ASR 1000 Series Routers that logs internal events. Tracing cannot be disabled on the
Tracing
Cisco ASR 1000 Series Router, and all tracing logs are stored in trace files.
Files that are automatically generated on the Cisco ASR 1000 Series Router that store trace data. Trace
Trace files
files are usually stored automatically in a storage directory and are often useful for customer support
purposes.
