Chapter 1: Features Overview
• Layer-3 flow filters (block IP or IPX traffic based on specific source-destination pairs)
• Layer-4 application filters (block traffic based on UDP or TCP source and destination
ports for IP or source and destination sockets for IPX)
Quality of Service
Although the SSR 2000 supplies non-blocking high-speed throughput, you can configure
the SSR 2000 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.
The SSR 2000 QoS is based on four queues: control, high, medium, and low. Control traffic
has the highest priority, high the second highest, and so on. The default priority for all
traffic is low.
You can configure QoS policies for the following types of traffic:
• Layer-2 prioritization (802.1p)
• Layer-3 and Layer-4 application flows
Statistics
The SSR 2000 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
Management Platforms
You can manage the SSR 2000 using the following management platforms:
• Command Line Interface (CLI) – An EMACs editor-like interface that accepts typed
commands and responds when applicable with messages or tables. You will use the
CLI to perform the basic setup procedures described in Chapter 3 of this guide.
• CoreWatch – Cabletron Systems’ Java-based device management software. CoreWatch
provides a graphical interface to the SSR 2000, providing most of the same monitoring
and control features as the CLI.
