Configuring VLANs

virtual interface group that has the same ID as the VLAN group. You can enter this command when you configure the VLAN group for the first time or later, after you have added tagged ports to the VLAN and so on.

The <num> parameter in the interface group-ve<num> command specifies the ID of the VLAN group with which you want to associate this virtual interface group. The VLAN group must already be configured and enabled to use a virtual interface group. The software automatically associates the virtual interface group with the VLAN group that has the same ID. You can associate a virtual interface group only with the VLAN group that has the same ID.

The syntax and usage for the ip address command is the same as when you use the command at the interface level to add an IP interface.

USING THE WEB MANAGEMENT INTERFACE

You cannot configure this feature using the Web management interface.

Displaying the VLAN Group and Virtual Interface Group Information

To verify configuration of VLAN groups and virtual interface groups, display the running-config file. If you have saved the configuration to the startup-config file, you also can verify the configuration by displaying the startup­ config file. The following example shows the running-config information for the VLAN group and virtual interface group configured in the previous examples. The information appears in the same way in the startup-config file.

HP9300(config)# show running-config

lines not related to the VLAN group omitted...

vlan-group 1 vlan 2 to 900 add-vlan 1001 to 1002 tagged ethe 1/1 to 1/2 router-interface-group

lines not related to the virtual interface group omitted...

interface group-ve 1

ip address 10.10.10.1 255.255.255.0

NOTE: If you have enabled display of sub-net masks in CIDR notation, the IP address information is shown as

follows: 10.10.10.1/24.

Allocating Memory for More VLANs or Virtual Interfaces

HP 9304M or HP 9308M routing switches 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 16.1 lists the default and configurable maximum number of VLANs.
