Cisco 12000 SIP-401, Cisco 12000 SIP-501, Cisco 12000 SIP-600, and Cisco 12000 SIP-601 Features
The Cisco 12000 SIP-401, Cisco 12000 SIP-501, Cisco 12000 SIP-600, and Cisco 12000 SIP-601 provide a common 10 Gbps forwarding and queuing engine responsible for packet classification, forwarding, queuing, and accounting without compromising performance. The Cisco 12000 SIP-401, Cisco 12000 SIP-501, Cisco 12000 SIP-600, and Cisco 12000 SIP-601 have two forwarding engines, one for ingress and one for egress. This allows the user to implement different features and QoS policies for the ingress and egress interfaces. The multicast replication is done by the egress forwarding engine, hence a very scalable multicast with built-in QoS.
The Modular Physical Layer Interface Module (PLIM) front end hosts up to 2 SPAs. Each SPA has a dedicated 10 Gbps interface to the SPA controller. The SPA controller uses a fair bandwidth allocation algorithm to share available and excess bandwidth between the 2 SPAs. The oversubscribed SPA does not cause any packet-drop on the nonoversubscribed SPA, and any unused bandwidth from one SPA is used by the other SPA.
The Cisco 12000 SIP-401, Cisco 12000 SIP-501, Cisco 12000 SIP-600, and Cisco 12000 SIP-601 support any combination of the following pluggable SPAs and Layer 2 encapsulations:
•
•
•
•
•
•
•
•
•
The SPA controller adapts the user traffic flowing between the SPA interfaces for the Layer 3 forwarding engine. The SPA controller has two levels of priority queuing with Deficit Round Robin (DRR) and Strict Priority Servicing. Strict Priority Servicing protects higher-priority packets by dropping lower priority packets first, in an oversubscribed configuration (persistent incoming traffic rate of 20 Gbps.)
The Cisco 12000 SIP-401, Cisco 12000 SIP-501, Cisco 12000 SIP-600, and Cisco 12000 SIP-601 provide the following key features:

The Cisco 12000 SIP-401, Cisco 12000 SIP-501, and Cisco 12000 SIP-601 provide the following key features not available on the Cisco 12000 SIP-400 and Cisco 12000 SIP-600:
•
The 12.0(32)S release allows you to specify the percentage of voltage increase. If you don't specify a percentage, the value used is the default percentage, which is 5%.
The output is enhanced to show nominal supply voltage, percentage margin, and actual read-back voltage, to validate that the expected values were written and actually applied successfully.
Note
Cisco 12000 SIP-400 Features
The Cisco 12000 SIP-400 is a 2.5 Gbps IP Services Engine (ISE) SIP that hosts SPAs used for applications that require a high level of performance, scalable physical and logical connections, and high-touch QoS and security features. The Cisco 12000 SIP-400 enhances and scales functionality with benefits previously available on the 2.5 G ISE line card, allowing carriers to offer services such as VoIP, MPLS VPN, Internet Access, and Low-speed Leased Line Aggregation (DS3, E3, CT3, n x T1, and n x DS0).
The Cisco 12000 SIP-400 provides a common 10 Gbps forwarding and queuing engine that handles packet classification, forwarding, queuing, and accounting without compromising performance. The forwarding engine, based on the 12000 Series ISE technology, features a unique edge-optimized, programmable adaptive network processor that combines the hardware performance of Application-Specific Integrated Circuits (ASICs) with the flexibility of software.
The Modular Physical Layer Interface Module (PLIM) front end hosts up to 4 SPAs. Each SPA has a dedicated 2.5 Gbps interface to the SPA controller. The Cisco 12000 SIP-400 supports any combination of the following pluggable SPAs and Layer 2 encapsulation:
•
•
•
•
•
•
The SPA controller adapts the traffic flowing between the SPA interfaces for the Layer 3 forwarding engine. The SPA controller has two levels of priority queuing with Deficit Round Robin (DRR) and Strict Priority Servicing. Strict Priority Servicing protects high priority traffic.
Key Features
The Cisco 12000 SIP-400 provides the following key features and benefits:

QoS
Traffic Shaping
Traffic Shaping offers additional value to service providers that want to build tiered service models. With traffic shaping, the Cisco 12000 SIP-400 can absorb bursts of traffic in both the ingress and egress directions. The Cisco 12000 SIP-400 supports up to 2048 input shaped queues and up to 1024 output shaped queues dynamically allocated to any interface or subinterface. Traffic can be shaped down to 64 kbps.
Traffic Rate Limiting and Marking
Traffic Rate Limiting and Marking, using Committed Access Rate (CAR) or Modular QoS CLI (MQC), allows service providers to control access to internal network resources. These features can be used to protect against Denial of Service (DoS) attacks or to deliver tiered services.
Traffic Prioritization through MDRR with Low Latency Queuing (LLQ)
Traffic Prioritization through MDRR with Low Latency Queuing (LLQ) offers class-based packet queuing that controls the packet dequeuing process to assure transit latency for differentiated flows. The Cisco 12000 SIP-400 supports the following queues:
•
•
•
•
Congestion Control through WRED and Query Management
Congestion Control through WRED and Query Management allows selective discard of low-priority flows before dropping packets from higher-priority flows.
Provider Edge
The Cisco 12000 SIP-400 provides the following comprehensive MPLS capabilities that support the development of service-optimized networks and can accelerate migration from circuit-based networks to packet-based networks:
•
•
•
•
•
•
•
Security
Access Control Lists (ACLs) and Unicast Reverse Packet Check (uRPF) provide security and access control by checking and filtering unwanted packets on specific interfaces. With ACLs, filtering can be done on source and destination IP addresses, transport protocols, and input and output interfaces.
Accounting
ISE accounting tools provide data for end-customer billing and network utilization monitoring. The Cisco 12000 SIP-400 provides the following accounting tools:
•
•
•
High Availability
The Cisco 12000 SIP-400 supports Online Insertion Removal (OIR) of SPAs; OIR of one SPA does not effect the traffic on other SPA interfaces.
The Cisco 12000 SIP-400 also supports Layer 3 NSF/SSO.
Supported MIBs
The following MIBs are supported in Cisco IOS Release 12.0(32)S for the Cisco 12000 SIP-600 on a Cisco 12000 series router:

Displaying the SPA Hardware Type
To verify the SPA hardware type that is installed in your Cisco 12000 Series Router, you can use the show gsr command.
Table 3-1 shows the hardware description that appears in the show command output for each type of SPA that is supported on the Cisco 12000 Series Router.
Example of the show gsr Command
The following example shows output from the show gsr command on a Cisco 12000 Series Router with a Cisco 12000 SIP-400 installed in slot 1 and a Cisco 12000 SIP-600 installed in slot 3:
