Route Switch Processors and Supervisor Engines

This chapter describes the route switch processors and supervisor engines supported on Cisco 7600 series routers and provides instructions for performing basic tasks on the modules. It contains the following sections:

• Overview

• Route Switch Processor 720

• Supervisor Engine 720 and Supervisor Engine 32

• Supervisor Engine 2

Note The route switch processor is the newest version of supervisor engine and it is supported in Cisco IOS Release 12.2SRB and later releases.

See Table 2-1 for a list of the route switch processor and supervisor engine configurations supported on Cisco 7600 series routers. Be sure to review the release notes for the software version running on your router for information about any restrictions and limitations that might apply.

Overview

The supervisor engine or route switch processor (RSP) is a module that is installed in one of the card slots in the router. The supervisor engine or RSP provides switching and local and remote management for the router and also contains the uplink ports for the router. Both types of modules (supervisor engine and RSP) perform the same functions in the router.

Note Cisco IOS Release 12.2SRB introduces support for RSP modules on Cisco 7600 series routers. In addition, the release introduces an enhanced version of the 9-slot chassis (CISCO7609-S) and several additional enhanced chassis are planned for future releases. These enhanced chassis provide increased power and cooling capabilities and an enhanced switch fabric to support high-power processors and future line cards.

Cisco 7600 series routers support the following types of RSPs and supervisor engines:

•Route Switch Processor 720—Supported on all chassis (including enhanced chassis) except the Cisco 7603 router and the Cisco OSR-7609.

•Supervisor Engine 720—Supported on all Cisco 7600 series routers.

•Supervisor Engine 32—Supported on all but the Cisco 7603 router.

•Supervisor Engine 2—Supported on all but the Cisco 7613 router. The Supervisor Engine 2 is no longer supported in Cisco IOS Release 12.2SRA and later releases.

Although the router can operate with a single supervisor engine or RSP, you can also install a second redundant module (of the same type) in the chassis. Only one module is active at a time. The second module acts as a "standby," serving as a backup if the active module fails.

Note If the system does not include a redundant supervisor engine or RSP, you can install another type of module in the slot reserved for the redundant supervisor engine or RSP.

The supervisor engine or RSP contains the following integrated daughter cards that perform forwarding and routing and provide the protocols supported on the router. Several configurations of daughter cards are supported (as shown in Table 2-1).

•Policy Feature Card (PFC) is the forwarding plane and does the following:

–Performs Layer 2 and Layer 3 forwarding.

–Enforces access control list (ACL) functions.

–Performs policing and marking for QoS traffic.

–Collects Netflow statistics.

Note A high-capacity (XL) PFC is also available. The XL version (PFC3BXL, PFC3CXL) provides more memory for more routing table and netflow cache capacity than a PFC. It allows routing and forwarding processes to be offloaded from the supervisor engine or RSP to the PFC, thus increasing the performance of the supervisor engine or RSP.

•Multilayer Switch Feature Card (MSFC) is the control plane and does the following:

–Performs routing for the chassis. The MSFC contains the route processor (RP) and switch processor (SP) for the router.

–Runs Layer 2 and Layer 3 protocols, such as the Spanning Tree Protocol (STP) and others. For information about supported protocols, see the Cisco 7600 Series Router Cisco IOS Software Configuration Guide and the release notes for the software version running on the router.

Table 2-1 lists the RSP and supervisor engine configurations supported on Cisco 7600 series routers. Specific combinations of processors and modules may not be supported in your chassis. See the release notes for your software version for information about supported combinations.

Route Switch Processor 720

This section describes the Route Switch Processor 720 (RSP720), which is the newest type of supervisor engine available for Cisco 7600 series routers. The Cisco 7600 RSP720 consists of a full-size board and two integrated daughter cards: the MSFC4 and a PFC3C or PFC3CXL. The RSP720 has an integrated switch fabric that interconnects all of the line cards in the Cisco 7600 router with point-to-point 20-Gbps full-duplex serial channels.

Note Cisco IOS Release 12.2SRB and later releases support the RSP720; earlier releases do not.

The RSP720 is supported on all Cisco 7600 routers (including enhanced chassis) except the Cisco 7603 and the Cisco OSR-7609.

Figure 2-1 shows the RSP720-3C-GE front panel, which is the same as the RSP720-3CXL-GE front panel. See Table 2-2 and Table 2-3 for information about the front-panel controls and LEDs.

Table 2-2 RSP720, Sup720, and Sup32 Front-Panel Controls
Component	Description
Status LEDs	Indicate the status of various functions on the module (see Table 2-3).
Reset Button	Restarts the router. Use a ballpoint pen tip or other small, pointed object to access the Reset button. Not all modules have a Reset button.
CompactFlash Disk Slots	One or two slots for flash memory cards. Do not remove the card from the slot while the disk LED is on. See the "Using Flash Memory Cards" section on page 3-12 for information about working with flash memory.
Console Port	Provides access to the router. The port is an EIA/TIA-232 asynchronous, serial connection with hardware flow control and an RJ-45 connector. See the "Connecting to the Console Port" section on page 3-9 for instructions on connecting to the console port. On the RSP720, the console port allows you to access either the switch processor (SP) or the route processor (RP).
Uplink Ports	Used to connect the router to other network devices. The uplink ports are configurable with small form-factor pluggable (SFP) or XENPAK optics modules. See the "Connecting to the Uplink Ports" section on page 3-10 for more information.
USB Ports (Sup32 only)	Each USB port can function as a console port or security key.

Front-Panel LEDs (RSP720, Sup720, Sup32)

LEDs on the front panel of the supervisor engine or route switch processor (RSP) show the status of the processor and other components installed in the router. Table 2-3 lists the LED functions on the Route Switch Processor 720, Supervisor Engine 720, and Supervisor Engine 32. See Table 2-5 for a list of LED functions on the Supervisor Engine 2.

Reset Button	Restarts the router. Use a ballpoint pen tip or other small, pointed object to access the Reset button.
Console Port	Provides access to the router either locally (with a console terminal) or remotely (with a modem). The port is an EIA/TIA-232 asynchronous, serial connection with hardware flow control and an RJ-45 connector. See the "Connecting to the Console Port" section on page 3-9 for instructions on connecting to the console port.
Console Port Mode Switch	Enables you to connect a terminal to the console port using either the cable and adapters provided with the router (switch in the in position, factory default) or a Catalyst 5000 Supervisor Engine III console cable and adapter, not provided (switch in the out position).
PCMCIA Slot and LED	PCMCIA flash memory card slot. Do not remove the card from the slot while the disk LED is on. See the "Using Flash Memory Cards" section on page 3-12 for information about working with flash memory.
Switch Load Meter	A visual approximation of the current traffic load across the backplane.
Uplink Ports	Used to connect the router to another network device. Two dual-port Gigabit Ethernet uplink ports operate in full-duplex mode only. You can configure the ports with any combination of copper, short-wave (SX), long-wave/long-haul (LX/LH), extended-reach (ZX), and CWDM 1000BASE-X Gigabit Interface Converters (GBICs). See the "Connecting to the Uplink Ports" section on page 3-10 for more information.
