1 ExtremeWare Over view
This chapter describes the following topics:
• Summary of Feat ures on page 17
• Security Licensing on page 20
• Software Factory Defaults on page 20
ExtremeWare is the full-featured software operating system that is designed to run on the
Summit 300-48 switch. This section describes the supported ExtremeWare features for the Summit

Summit 300-48 Switch Software User Guide 17
ExtremeWare Overview
• SSH2 connec tion
• Simple Network M anagement Protocol (SNM P) support
• Remote Monitoring (RMON)
• Traffic mirroring for ports
Unified Access
The Summit 300-48 supports the Unified Access architecture, enabling wired and wireless applications
across a completely integrated enterprise infrastructure. With the Altitude product line, the Summit
300-48 supports 802.11 WLAN connectivity. Provisioning of Unified Access is completely controlled by
the Summit 300-48.
Virtual LANs (VLANs)
ExtremeWa re has a VLAN feature that enables you to construct your broadcast domains without being
restricted by physical connections. A VLAN is a group of location- and topolog y-independent devices
that communicate as if they were on the same physical local area network (LAN).
Implementing VLANs on your network has the following three advantages:
• They help to control broadcast traffic. If a device in VLAN Marketing transmits a broadcast frame,
only VLAN Marketing devices receive the frame.
• They provide extra security. Devices in VLAN Marketing can only communicate with devices on
VLAN Sales using routing services.
• They ease the change and movement of devices on networks.
NOTE
For more information on VLANs, see Chapte r 5, “Virtual LANs (VLA Ns)”.
Spanning Tree Protocol
The Summit 300-48 supports the IEEE 802.1D Spanning Tree Protocol (STP), which is a bridge-based
mechanism for providing fault tolerance on netw orks. STP enables you to implem ent parallel paths for
network traffic, and ensure that:
• Redundant paths are disabled when the main paths are operational.
• Redundant paths are enabled if the main traffic paths fail.
A single spanning tree can span multi ple VLANs.
NOTE
For more information on STP, see Chapte r 13, “Spanning Tree Protocol (STP)”.
18 Summit 300-48 Switch Software User Guide
Software Licensing
Quality of Service
ExtremeWare has Quality of Service (QoS) features that support IEEE 802.1p, MAC QoS, and four
queues. These features enable you to specify service levels for different traffic groups. By default, all
traffic is assigned the “normal” QoS policy profile. If needed, you can create other QoS policies and
rate-limiting access control lists and apply them to di fferent traffic types so that they have different
maximum bandwidth, and priority.
NOTE
For more information on Quality of Service, see Chap ter 11, “Quality of Ser vice (QoS)”.
Load Sharing
Load sharing allows you to increase bandwidth and resiliency by usi ng a group of ports to carry traffic
in parallel between systems. The sharing algorithm allows th e switch to use multiple ports as a single
logical port. For example, VLANs see the lo ad-sharing group as a single vi rtual port. The algorithm also
guarantees packet sequencing between clients.
NOTE
For information on load shar ing, see Chapter 4, “Config uring Ports on a Sw itch”.
ESRP-Aware Switches
Extreme switches that are not running ESRP, but are connected on a network that has other Extreme
switches running ESRP are ESRP-aware. When ESRP-aware switches are attached to ESRP-enabled
switches, the ESRP-aware switches reliably perform f ail-over and fail-back scenarios in the prescribed
recovery times. No configuration of th is feature is necessary.
If Extreme switches running ESRP are connected to layer 2 switches that are not manufactured by
Extreme Networks (or Extreme switches that are not running ExtremeWare 4.0 or above), the fail-over
times seen for traffic local to the segment m ay appear longer, depending on the application involved
and the FDB timer used by the other vendor ’s layer 2 switch. As such, ESRP can be used with layer 2
switches from other vendors, but the recovery times vary.
The VLANs associated with the ports connecting an ESRP-aware switch to an ESRP-enabled switch
must be configured using an 802.1Q tag on the connecti ng port, or, if only a single VLAN is involved, as

any. E SRP will not function correctly if the ESR P-aware switch
Software Licensing
Summit 300-48 switches support Advanced Edge licensing.

ExtremeWare Overview
Security Licensing
Certain additional ExtremeWare security features, such as the use of Secure Shell (SSH2) encryption,
may be under United States export restriction control. Extreme Networks ships these security features in
a disabled state. You can obtain information on enabling these features at no charge from Extreme
Networks.
Obtaining a Security License
To obtain information on enabling features that require export restriction, access the Extreme Networks
Support website at:
http://www.extremenetworks.com/go/security.htm
Fill out a contact form to indica te compliance or noncomplia nce with the export restrictions. If you are
in compliance, you will be given in formation that will allo w you to enable security fea tures.
Security Features Under License Control
ExtremeWare version 6.0 and above supports the SSH2 protocol. SSH2 allows the encryption of session
data. The encryption methods used are under U.S. export restriction control.

This chapter describes the following topics:
• Understanding the Comman d Syntax on page 23
• Line-Editing Keys on page 25
• Command History on page 26
• Common Commands on page 26
• Configuring Management Access o n page 28
• Domain Name Service Client Services on page 31
• Checking Basic Connectivity on page 32
Understanding the Command Syntax
This section describes the steps to take when entering a command. Refer to the sections that follow for
detailed information on us ing the command-line interf ace (CLI).
When entering a command at the prompt, ensure that you have the appropriate privilege level. Most
configuration commands require you to have the ad ministrator privilege level. To use the CLI, follow
these steps:
1 Enter the command name.
If the command does not include a parameter or values, skip to step 3. If the command requires
more information, continue to step 2.
2 If the command includes a parameter, enter the parameter name and values.
3 The value part of the command specifies how you want the parameter to be set. Values include
numerics, strings, or addresses, depending on the parameter.
4 After entering the complete command, press [Return].
NOTE
If an asterisk (*) appe ars in front of the comm and-line prompt, it in dicates that you have outstanding
configuration changes that have not been saved. For more informa tion on saving con figuration chang es,
see Appendix C, “Software Upgrade and B oot Options”.
Summit 300-48 Switch Software User Guide 23
Accessing the Switch
Syntax Helper
The CLI has a built-in syntax helper. If you are unsure of the complete syntax for a particular command,
enter as much of the command as possible and press [Return]. The syntax helper provides a list of
options for the remainde r of the command.
The syntax helper also provides assistance if you have entered an incorrect command.
Command Completion with Syntax Helper
ExtremeWare provides command completion by way of the [Tab] key. If you enter a partial command,
pressing the [Tab] key posts a list of available options, and places the cursor at the end of the command.
Abbreviated Syntax
Abbreviated syntax is the most unambiguous, sh ortest allowable abbreviation of a com mand or
parameter. Typically, th is is the first three letters of the command.
In command tables throughout this guide, abbreviated syntax is noted using bold characters.
NOTE
When using abbreviated syntax, you must enter enough characters to ma ke the command
unambiguous and disti nguishable to the switch.
Command Shortcuts
All named components of the switch configuration must have a unique name. Components are named
using the
create command. When you enter a command to configure a named component, you do not
need to use the keyword of the component. For example, to create a VLAN, you must enter a unique
VLAN name:
create vlan engineering
After you have created the VLAN with a unique name, you can then elimin ate the keyword vlan from
all other commands that require the name to be entered. For example, on the stand-alone switch,
instead of entering the command
config vlan engineering delete port 1:1-1:3,1:6
you could enter the following shortcut:
config engineering delete port 1:1-1:3,1:6
Summit 300-48 Switch Numerical Ranges
Commands that require you to enter one or more slot:port numbers on a Summit 300-48 switch use the
parameter
port 1:1-1:3
<portlist> in the syntax. A portlist can be a range of numbers, for example:
You can add additional slot and port numbers to the list, separated by a comma:
port 1:1-1:3, 1:6,1:8

Line-Editing Keys
Names
All named components of the switch configuration must have a unique name. Names must begin with
an alphabetical character and are delimited by w hitespace, unless enclosed in qu otation marks.
Symbols
You may see a variety of symbols shown as part of the command syntax. These symbols explain how to
enter the command, and you do not type them as part of the com mand itself. Table 4 summarizes
command syntax symbols.
Table 4: Command Syntax Symbol s
angle brackets < > Enclose a variable or value. You must specify the variable or value. For
example, in the syntax
config vlan <name> ipaddress <ip_address>
you must supply a VLAN name for <name> and an address for
<ip_address> when entering the command. Do not type the angle
brackets.
square brackets [ ] Enclose a required value or list of required arguments. One or more
values or arguments can be specified. For example, in the syntax
use image [primary | secondary]
you must specify either the primary or secondary image when entering
the command. Do not type the square brackets.

Configuring Mana gement Access
ExtremeWare supports the following two levels of man agement:
• User
• Administrator
In addition to the management levels, you can optional ly use an external RADIUS server to provide CLI
command authorization checking for each command. For more information on RADIUS, see “RADIUS
Client” in Chapter 3, “Managing the Switch”.

User Account
A user-level account has viewing access to all manageable parameters, with the exception of:
• User account database.
• SNMP community strings.
A user-level account can use the ping command to test device reachability, and change the password
assigned to the account name. If you h ave logged on with user capabilit ies, the command-line prompt
ends with a (>) sign. For example:
Summit 300-48:2>
Administrator Account
An administrator-level account can view and ch ange all switch parameters. It can also add and delete
users, and change the password associated with any account name. The administrator can disconnect a
management session that has been established by way of a Telnet connection. If this happens, the user
logged on by way of the Telnet connection is notified that the session has been terminated.
If you have logged on with administrator capabilities, the command-line prompt ends with a (#) sign.
For example:
Summit 300-48:18#
Prompt Text
The prompt text is taken from the SNMP sysname setting. The number that follows the colon indicates
the sequential line /command number.
If an asterisk (*) appears in front of the command-line prompt, it indicates tha t you have outstanding
configuration changes that have not been saved. For example:
*Summit 300-48:19#
Default Accounts
By default, the switch is configured with t wo accounts, as shown in Table 7.
