Limitations And Restrictions; Performance Route Processor - Cisco CRS-1 System Description

Limitations and Restrictions

6 STATUS LED
The DRP PLIM front panel contains the following components:
• CONSOLE and AUX ports (one set of ports for each SMP)—Provide RJ-45 serial interfaces for local
• Management Ethernet ports (one port for each SMP)—Provide a 10/100/1000 Ethernet interface for
• Two 40-gigabyte removable hard disk drives (one for each SMP)—Store troubleshooting and debugging
• Two PCMCIA flash disk slots (one for each SMP)—Accept a 1-gigabyte PCMCIA flash card for storing
• Alphanumeric LED (eight-digit display)—Indicates the status of the DRP and DRP PLIM cards.
• DRP PLIM power consumption—20 W
Limitations and Restrictions
The current Cisco CRS 8-slot Line Card Chassis Enhanced router multishelf system supports DRP functionality,
with the following limitations:
• Each line card chassis supports one DRP and one DRP PLIM. In the future, each line card chassis will
• Redundant DRP operation (or DRP pairing ) is currently not supported. In the future, you will be able
• For processes to run on the DRP, you must override the default process placement policy and configure

Performance Route Processor

Note For the Cisco CRS-X, the PRP is required instead of the RP.
The Performance Route Processor (PRP) is also available for the Cisco CRS 8-slot Line Card Chassis Enhanced
router. The PRP provides enhanced performance for both route processing and system controller functionality.
Two PRP cards are required per chassis for a redundant system. The PRP can be inserted in either of the two
dedicated RP slots in the Cisco CRS 8-slot Line Card Chassis Enhanced router. When two PRPs are installed,
one PRP is the "Active" RP and the other is the "Standby" RP.
The following figure shows the PRP card.

to install a pair of DRPs in the chassis and configure them for high availability. When paired, the DRPs

placement policy assigns processes to paired DRPs only.
