Product Overview

This chapter describes the ATM switch processor (ASP) and multiservice switch route processor (MSRP), which are referred to generically as the processor card. The processor card is shown in Figure 1-1. This card contains the main system processor that includes the ATM switching engine and network management processor for the system software and most of the system memory components. The processor card maintains and executes the management functions that control the system. You can install the processor card in the following systems:

• Slot 2 of the Catalyst 8510 MSR chassis

• Slot 13 of the Catalyst 5500 switch chassis

• Slot 2 of the LightStream  1010 ATM switch chassis

This chapter describes the processor card features in the following sections:

• Flash Memory SIMM

• PCMCIA Card Slots

• DRAM SIMMs

• LEDs

• Reset Switch

• Ethernet Port

• Auxiliary and Console Ports

• Feature Card

Flash Memory SIMM

With the Flash memory SIMM, you can load and store system software images remotely. You can download a new software image over the network, or from a local server, and add the new image to Flash memory or replace an existing image.

PCMCIA Card Slots

The processor card has two Personal Computer Memory Card International Association (PCMCIA) card slots into which you can install up to two Type II Flash memory cards. (See Figure 1-2.) You can store the system software and configuration information on these cards. You can also configure the system to boot from a software image stored on the Flash memory card.

DRAM SIMMs

Dynamic random-access memory (DRAM) single in-line memory modules (SIMMs) to store incoming and outgoing packets, queues, and caches (32-MB default for the feature card per-class queuing [FC-PCQ] or 64-MB default for the feature card per-flow queuing [FC-PFQ]).

LEDs

The LEDs on the processor card indicate the status of the processor card, fan assembly, and power supplies. (See Figure 1-3.)

Reset Switch

The reset switch is at the left side of the processor card faceplate, through a small hole between two columns of LEDs. You can use the reset switch when a software-initiated reset is not possible. (See Figure 1-3.)

Ethernet Port

The processor card includes one RJ-45 Ethernet port (labeled Enet) that you can use to connect a management workstation for SNMP management. (See Figure 1-3.)

Auxiliary and Console Ports

The processor card includes one auxiliary port (labeled AUX) and one console port (labeled CONSOLE), shown in Figure 1-4.

Feature Card

The feature card (see Figure 1-5) is a daughter card on the processor card that provides a number of value-added features in addition to the basic switch functionality.

FC-PCQ and FC-PFQ

There are two types of feature cards: feature card per-class queuing (FC-PCQ) and feature card per-flow queuing (FC-PFQ). FC-PCQ provides a subset of the ATM Forum traffic management features provided by FC-PFQ, as described in Table 1-1.

Table 1-1: FC-PCQ and FC-PFQ Feature Comparison

Feature	FC-PCQ	FC-PFQ
Traffic classes	CBR1, RT-VBR2, NRT-VBR3, ABR4 (EFCI5 and RR6), UBR7	CBR, RT-VBR, NRT-VBR, ABR (EFCI and RR), UBR
Output queuing	Four classes per port	Per-VC or per-VP
Output scheduling	Strict priority	Strict priority, rate scheduling, and WRR8
Intelligent early packet discard	Multiple fixed thresholds	Multiple, weighted, dynamic thresholds
Intelligent tail (partial) packet discard	Supported	Supported
Selective cell marking and discard	Multiple fixed thresholds	Multiple, weighted, dynamic thresholds
Shaping	Per-port (pacing)	Per-VC or per-VP (128 shaped VP  tunnels)
Policing (UPC9)	Dual mode, single leaky bucket	Dual leaky bucket
Frame mode VC-merge	-	Supported
Point-to-multipoint VC (multicast)	One leaf per output port, per point-to-multipoint	Multiple leaves per output port, per point-to-multipoint
Network clock switchover	Automatic upon failure	Programmable clock selection criteria
Nondisruptive snooping	Per-port transmit or receive	Per-VC, per-VP, or per-port

1CBR = constant bit rate. 2RT-VBR = real-time variable bit rate. 3NRT-VBR = nonreal-time variable bit rate. 4ABR = available bit rate. 5EFCI = Explicit Forward Congestion Indication. 6RR = relative rate. 7UBR = unspecified bit rate. 8WRR = weighted round-robin. 9UPC = usage parameter control.

Table 1-2 lists the processor card and feature card options supported by system type.
