Introduction
Introduction
This Advanced Traffic Management Guide describes how to manage and
configure advanced traffic management features on your switch. It supports
the following switches:
■ ProCurve Switch 2810
For an overview of other product documentation for the above switches, refer
to “Product Documentation” on page xi.
You can download a copy from the ProCurve Networking website, http://
www.procurve.com.
Conventions
This guide uses the following conventions for command syntax and displayed
information.
Feature Descriptions by Model
In cases where a software feature is not available in all of the switch models
covered by this guide, the section heading specifically indicates which product
or product series offer the feature.
For example (the switch model is highlighted here in bold italics):
“Jumbo Packet Support on the 2810 Switch”.

Getting Started
Conventions
■ Braces within square brackets ( [ < > ] ) indicate a required element
within an optional choice.
■ Boldface indicates use of a CLI command, part of a CLI command
syntax, or other displayed element in general text. For example:
“Use the copy tftp command to download the key from a TFTP server.”
■ Italics indicate variables for which you must supply a value when
executing the command. For example, in this command syntax, < port-
list > indicates that you must provide one or more port numbers:
Syntax: aaa port-access authenticator < port-list >
Command Prompts
In the default configuration, your switch displays one of the following CLI
prompts:
ProCurve Switch 2810#
To simplify recognition, this guide uses ProCurve to represent command
prompts for all models. For example:
ProCurve#
(You can use the hostname command to change the text in the CLI prompt.)

In some cases, brief command-output sequences appear outside of a
numbered figure. For example:
ProCurve(config)# ip default-gateway 18.28.152.1/24
ProCurve(config)# vlan 1 ip address 18.28.36.152/24
ProCurve(config)# vlan 1 ip igmp
Port Identity Examples
This guide describes software applicable to both chassis-based and stackable
ProCurve switches. Where port identities are needed in an example, this guide
uses the chassis-based port identity system, such as “A1”, “B3 - B5”, “C7”, etc.
However, unless otherwise noted, such examples apply equally to the
stackable switches, which for port identities typically use only numbers, such
as “1”, “3-5”, “15”, etc.

Static Virtual LANs (VLANs)
Overview
Overview
This chapter describes how to configure and use static, port-based VLANs on
the switches covered by this manual.
For general information on how to use the switch’s built-in interfaces, refer
to these chapters in the Management and Configuration Guide for your
switch:
■ Chapter 3, “Using the Menu Interface”
■ Chapter 4, “Using the Command Line Interface (CLI)”
■ Chapter 5, “Using the Web Browser Interface”
■ Chapter 6, “Switch Memory and Configuration”

A VLAN is a group of ports designated by the switch as belonging to the same
broadcast domain. (That is, all ports carrying traffic for a particular subnet
address would normally belong to the same VLAN.)
Note This chapter describes static VLANs, which are VLANs you manually config-
ure with a name, VLAN ID (VID), and port assignments. (For information on
dynamic VLANs, see chapter 3, “GVRP”.)
page 2-20 page 2-25
page 2-19 page 2-25
Using a VLAN, you can group users by logical function instead of physical
location. This helps to control bandwidth usage by allowing you to group highbandwidth users on low-traffic segments and to organize users from different
LAN segments according to their need for common resources.
By default, 802.1Q VLAN support is enabled for eight VLANS. You can configure up to 256 VLANs on the switch.
(802.1Q compatibility enables you to assign each switch port to multiple
VLANs, if needed, and the port-based nature of the configuration allows
interoperation with older switches that require a separate port for each
VLAN.)
General Use and Operation. Port-based VLANs are typically used to
reduce broadcast traffic and to increase security. A group of network users
assigned to a VLAN forms a broadcast domain that is separate from other
VLANs that may be configured on a switch. On a given switch, packets are
forwarded only between ports that belong to the same VLAN. Thus, all ports
carrying traffic for a particular subnet address should be configured to the
same VLAN. Cross-domain broadcast traffic in the switch is eliminated and

Static Virtual LANs (VLANs)
Port-Based Virtual LANs (Static VLANs)
bandwidth is saved by not allowing packets to flood out all ports. Separate
VLANs on the switch can communicate with each other through an external
router.
For example, referring to figure 2-1, if ports A1 through A4 belong to VLAN_1
and ports A5 through A8 belong to VLAN_2, traffic from end-node stations on
ports A2 through A4 is restricted to only VLAN_1, while traffic from ports A5
through A7 is restricted to only VLAN_2. For nodes on VLAN_1 to communicate with VLAN_2, their traffic must go through an external router via ports
A1 and A8.

Overlapping (Tagged) VLANs. A port on the switch can be a member of
more than one VLAN if the device to which it is connected complies with the
802.1Q VLAN standard. For example, a port connected to a central server using
a network interface card (NIC) that complies with the 802.1Q standard can be
a member of multiple VLANs, allowing members of multiple VLANs to use the
server. Although these VLANs cannot communicate with each other through
the server, they can all access the server over the same connection from the
switch. Where VLANs overlap in this way, VLAN “tags” are used to distinguish
between traffic from different VLANs.

through a single switch-to-switch link.

Introducing Tagged VLAN Technology into Networks Running Legacy
(Untagged) VLANs. You can introduce 802.1Q-compliant devices into net-
works that have built untagged VLANs based on earlier VLAN technology. The
fundamental rule is that legacy/untagged VLANs require a separate link for
each VLAN, while 802.1Q, or tagged VLANs can combine several VLANs in one
link. This means that on the 802.1Q-compliant device, separate ports (configured as untagged) must be used to connect separate VLANs to non-802.1Q
devices.

Overview of Using VLANs
VLAN Support and the Default VLAN
In the factory default configuration, all ports on the switch belong to the
default VLAN (named DEFAULT_VLAN). This places all ports in the switch
into one physical broadcast domain. In the factory-default state, the default
VLAN is the primary VLAN.
You can partition the switch into multiple virtual broadcast domains by adding
one or more additional VLANs and moving ports from the default VLAN to the
new VLANs. You can change the name of the default VLAN, but you cannot
change the default VLAN’s VID (which is always “1”). Although you can remove
all ports from the default VLAN, this VLAN is always present; that is, you
cannot delete it from the switch.
The Primary VLAN
Because certain features and management functions, such as single IPaddress stacking, run on only one VLAN in the switch, and because DHCP and
Bootp can run per-VLAN, there is a need for a dedicated VLAN to manage these
Port-Based Virtual LANs (Static VLANs)
Static Virtual LANs (VLANs)
features and ensure that multiple instances of DHCP or Bootp on different
VLANs do not result in conflicting configuration values for the switch. The
primary VLAN is the VLAN the switch uses to run and manage these features
and data. In the factory-default configuration, the switch designates the
default VLAN (DEFAULT_VLAN) as the primary VLAN. However, to provide
more control in your network, you can designate another VLAN as primary.
To summarize, designating a non-default VLAN as primary means that:
■ The stacking feature runs on the switch’s designated primary VLAN
instead of the default VLAN
■ The switch reads DHCP responses on the primary VLAN instead of on the
default VLAN. (This includes such DHCP-resolved parameters as the
TimeP server address, Default TTL, and IP addressing—including the
Gateway IP address—when the switch configuration specifies DHCP as
the source for these values.)
■ The default VLAN continues to operate as a standard VLAN (except, as
noted above, you cannot delete it or change its VID).
■ Any ports not specifically assigned to another VLAN will remain assigned
to the Default VLAN, regardless of whether it is the primary VLAN.
Candidates for primary VLAN include any static VLAN currently configured
on the switch. (A dynamic—GVRP-learned—VLAN that has not been converted to a static VLAN cannot be the primary VLAN.) To display the current
primary VLAN, use the CLI show vlan command.
Note If you configure a non-default VLAN as the primary VLAN, you cannot delete
that VLAN unless you first select a different VLAN to act as primary.
If you manually configure a gateway on the switch, it will ignore any gateway
address received via DHCP or Bootp.

Per-Port Static VLAN Configuration Options
The following figure and table show the options you have for assigning
individual ports to a static VLAN. Note that GVRP, if configured, affects these
options and VLAN behavior on the switch. The display below shows the perport VLAN configuration options. Table 2-1 briefly describes these options.
