ter 1 SmartSwitch Router Product

Overview

The 8-slot SmartSwitch Router (SSR-8) provides non-blocking, wire-speed Layer-2

(switching), Layer-3 (routing) and Layer-4 (application) switching. The hardware

provides wire-speed performance regardless of the performance monitoring, filtering,

and Quality of Service (QoS) features enabled by the software. You do not need to

accept performance compromises to run QoS or access control lists (ACLs).

The following table lists the basic hardware and software specifications for the SSR-8.

Feature Specification

Throughput • 16-Gbps non-blocking switching fabric

• 15 million packets-per-second routing throughput

Capacity • Up to 250,000 routes

• Up to 2,000,000 Layer-4 application flows

• 400,000 Layer-2 MAC addresses

• 4,096 Virtual LANs (VLANs)

• 20,000 Layer-2 security and access-control filters

• 3MB input/output buffering per Gigabit port

• 1MB input/output buffering per 10/100 port

Routing protocols • IP: RIPv1/v2, OSPF

• IPX: RIP, SAP

• Multicast: IGMP, DVMRP

Bridging and

VLAN protocols

• 802.1d Spanning Tree

• 802.1Q (VLAN trunking)

Media Interface

protocols

• 802.3 (10Base-T)

• 802.3u (100Base-TX, 100BASE-FX)

• 802.3x (1000Base-SX, 1000Base-LX)

• 802.3z (1000Base-SX, 1000Base-LX)

Supported Media (Encapsulation Type)

The SSR supports the following industry-standard networking media:

• IP: IEEE 802.3 SNAP and Ethernet Type II

• IPX: IEEE 802.3 SNAP, Ethernet Type II, IPX 802.3, 802.2

• 802.1Q VLAN Encapsulation

Supported Routing Protocols

The SSR supports many routing protocols based on open standards. The SSR can

receive and forward packets concurrently from any combination of the following:

• Interior Gateway Protocols

• Open Shortest Path First (OSPF) Version 2

• Routing Information Protocol (RIP) Version 1, 2

Quality of Service

(QoS)

• Layer-2 prioritization (802.1p)

• Layer-3 source-destination flows

• Layer-4 source-destination flows

• Layer-4 application flows

RMON • RMONv1/v2 for each port

Management • SNMP

• CoreWatch Element Manager (GUI)

• Emacs-like Command Line Interface (CLI)

Port mirroring • Traffic to Control Module

• Traffic from specific ports

• Traffic to specific chassis slots (line cards)

Hot swapping • Power supply (when redundant supply is installed

and online)

Redundancy • Redundant and hot-swappable power supplies
