Brocade FastIron Ethernet Switch Platform and Layer 2 Switching Configuration Guide - Manual (Page 398)

The number of VLANs and virtual routing interfaces supported on your product depends on the device
and, for Chassis devices, the amount of DRAM on the management module. The following table lists
the default and configurable maximum numbers of VLANs and virtual routing interfaces for Layer 2
and Layer 3 Switches. Unless otherwise noted, the values apply to both types of switches.
VLAN and virtual routing interface support TABLE 55
VLANs Virtual routing interfaces
Default maximum Configurable maximum Default maximum Configurable maximum
64 4094 255 512
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. Refer to
VLAN groups and virtual routing interface group on page 394.
Increasing the number of VLANs you can configure
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.
To increase the maximum number of VLANs you can configure, enter commands such as the
following at the global CONFIG level of the CLI.
device(config)# system-max vlan 2048
device(config)# write memory
device(config)# end
device# 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. Refer to
Table 55 on page 398.
Increasing the number of virtual routing interfaces you can configure
To increase the maximum number of virtual routing interfaces you can configure, enter commands
such as the following at the global CONFIG level of the CLI.
device(config)# system-max virtual-interface 512
device(config)# write memory
device(config)# end
device# reload
Syntax: system-max virtual-interface num
The num parameter indicates the maximum number of virtual routing interfaces. The range of valid
values depends on the device you are configuring. Refer to
Table 55 on page 398.
