Allocating Memory For More Vlans Or Virtual Routing Interfaces - HP ProCurve 9304M Installation And Configuration Manual

Allocating Memory for More VLANs or Virtual Routing Interfaces

HP 9300 series Routing Switches with Management II or higher modules support up to 4095 VLANs and 4095
virtual interfaces.
The number of VLANs and virtual interfaces supported depends on the amount of DRAM memory on the
management module. Table 11.1 lists the default and configurable maximum number of VLANs for Management
II and higher modules.

NOTE: If many of your VLANs will have an identical configuration, you might want to configure VLAN groups and
virtual routing interface groups after you increase the system capacity for VLANs and virtual routing interfaces.
See "Configuring VLAN Groups and Virtual Routing Interface Groups" on page 11-38.
Increasing the Number of VLANs You Can Configure
To increase the size of the VLAN table, which determines how many VLANs you can configure, use either of the
following methods.
NOTE: Although you can specify up to 4095 VLANs, you can configure only 4094 VLANs. VLAN ID 4094 is
reserved for use by the Single Spanning Tree feature.
USING THE CLI
To increase the maximum number of VLANs you can configure, enter commands such as the following at the
global CONFIG level of the CLI:
HP9300(config)# system-max vlan 2048
HP9300(config)# write memory
HP9300(config)# end
HP9300# reload
Syntax: system-max vlan <num>
The <num> parameter indicates the maximum number of VLANs. The range of valid values depends on the
device you are configuring.
USING THE WEB MANAGEMENT INTERFACE
To modify a table size using the Web management interface:
1. Log on to the device using a valid user name and password for read-write access. The System configuration
panel is displayed.
