2-6 Riverstone Networks RS 32000 Switch Router Getting Started Guide

Software Overview Introduction

• Layer-4 application ACLs (block traffic based on UDP or TCP source and destination ports for IP

or source and destination sockets for IPX)

In addition to filtering and ACL, the RS also provides login security in the form of TACACS, TACACS+, RADIUS,

and Secure Session Shells (SSH) version 1.5.

2.3.6 Quality of Service

Although the RS 32000 supplies non-blocking, wire-speed throughput, you can configure the RS to apply Quality of

Service (QoS) policies during peak periods to guarantee service to specific hosts, applications, and flows

(source-destination pairs). This is especially useful in networks where the traffic level can exceed the network

medium’s capacity.

QoS policies can be configured for the following types of traffic:

• Layer-2 prioritization (802.1p)

• Layer-3 source-destination flows

• Layer-4 source-destination flows

• Layer-4 application flows

QoS mechanisms supported on the RS 32000 include the following:

• Traffic control queuing

• Weighted random early detection

• Weighted fair queuing

• Strict priority queuing

• QoS traffic control queues

• ToS octet rewrites

• Multi-Protocol Label Switching (MPLS) and the creation of LSPs for traffic engineering

Note Traffic control queuing is based on assigning traffic to one of four queues: control,

high, medium, and low. Control traffic (routing protocols, and so on) has the

highest priority, high the second highest, and so on. The default priority for all

traffic is low.

2.3.7 Statistics

The RS 32000 can provide extensive statistical data on demand. You can access the following types of statistics:

Layer-2 RMON and MIB II Statistics – Port statistics for normal packets and for errors (packets in, packets out, CRC

errors, and so on)

Layer-3 RMON v2 Statistics – Statistics for ICMP, IP, IP-interface, IP routing, IP multicast, VLAN

Layer-4 RMON v2 Statistics – Statistics for TCP and UDP

LFAP – Light-weight File Accounting Protocol

Open APIs – Slate and FAS Lite.
