Enterasys Networks 2000 사용자 설명서

Although the XP-2000 supplies non-blocking high-speed throughput, you can configure the XP-
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 XP-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 source-destination flows

•

Layer-4 source-destination flows

•

Layer-4 application flows

The XP-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 

You can manage the XP-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.

•

SNMP MIBs and traps – The XP-2000 supports SNMP v1 and many standard networking 
MIBs. You can access the XP-2000’s SNMP agent using Enterasys integration software for HP 
OpenView 5.x on Windows NT or Solaris 2.x, or Enterasys Spectrum on Solaris 2.x. 

, in this guide explains how to set up SNMP on the XP-2000.
