Supported SIP Features

The Cisco ASR1000-SIP10, is a high-performance, feature-rich SPA interface processor that functions as a carrier card for shared port adapters (SPAs) on the Cisco ASR 1000 Series Aggregation Services Routers. The SIP is supported on the Cisco ASR 1000 Series Routers, and is compatible with one or more platform-independent SPAs. For more information on SPA compatibility, see the "SIP and SPA Compatibility" section.

This section provides a list of some of the primary features supported by the SIP hardware and software. For feature compatibility information by SIP and SPA combination, and information about configuring these features, see Chapter 4 "Configuring the SIP."

The Cisco ASR1000-SIP10 supports the standard FPD upgrade methods for the Cisco ASR 1000 Series Routers. For more information about FPD support, see Chapter 26 "Upgrading Field-Programmable Devices."

Cisco ASR1000-SIP40 Features

The Cisco ASR1000-SIP40 supports upto 40 Gbps total bandwidth for the four SPA bays and 46 Gbps sustained through carrier card when utilizing two four-link 6.25 GHz ESIs. Following are the features of the Cisco ASR1000-SIP40:

•It supports 40 Gbps of non oversubscribed throughput.

•Compatible with existing and future SPAs, ESPs, and RPs.

•It supports online-insertion-and-removal (OIR) of all SIP-10 SPAs and Cisco ASR1000-SIP40.

•Provides higher port density support of 48 point dual priority, and 96 point single priority.

•Enables enhanced QoS and timestamp support.

•Performs ingress packet prioritization based on Layer 2 or Layer 3 headers.

•Enables the flow-control the SPAs.

•Distributes line clocking reference from a single SPA to the RPs.

•It supports Onboard Failure Logging (OBFL).

•All the SPAs on Cisco ASR1000-SIP40 provide FPD support.

•From Release 3.7.0S onward, the Cisco ASR1000-SIP40 is supported on all the routers that support the Cisco ASR1000-SIP10.
