is it possible to assign all available vlans on certain port ?

hello, we are running FCX things here.

on 3Com switches we used to do the following setup

in gi 1/0/1

port link-type trunk

port trunk permit vlan all

and voila, all avalable vlans are assigned as tagged to certain port (and even new ones)

is it possible to do that in Brocade FCX?

Hi chipitsine

     The answer is not in the same way, however you can use VLAN groups - see below from the manual.

Configuring VLAN groups and virtual routing interface groups

To simplify configuration when you have many VLANs with the same configuration, you can configure VLAN groups and virtual routing interface groups.

NOTE

VLAN groups are supported on Layer 3 Switches and Layer 2 Switches. Virtual routing interface groups are supported only on Layer 3 Switches.

When you create a VLAN group, the VLAN parameters you configure for the group apply to all the VLANs within the group. Additionally, you can easily associate the same IP subnet interface with all the VLANs in a group by configuring a virtual routing interface group with the same ID as the VLAN group.

The VLAN group feature allows you to create multiple port-based VLANs with identical port members. Because the member ports are shared by all the VLANs within the group, you must add the ports as tagged ports. This feature not only simplifies VLAN configuration but also allows you to have a large number of identically configured VLANs in a startup-config file on the device flash memory module. Normally, a startup-config file with a large number of VLANs might not fit on the flash memory module. By grouping the identically configured VLANs, you can conserve space in the startup-config file so that it fits on the flash memory module.

Configuring a VLAN group

To configure a VLAN group, enter commands such as the following.

Brocade(config)# vlan-group 1 vlan 2 to 257

Brocade(config-vlan-group-1)# tagged 1/1 to 1/2

The first command in this example begins configuration for VLAN group 1, and assigns VLANs 2 through 257 to the group. The second command adds ports 1/1 and 1/2 as tagged ports. Because all the VLANs in the group share the ports, you must add the ports as tagged ports.

Syntax: vlan-group <num> vlan <vlan-id> to <vlan-id>

Syntax: tagged ethernet <portnum> <portnum> | Ethernet <portnum>]

The vlan-group <num> parameter specifies the VLAN group ID and can be from 1 – 32. The vlan <vlan-id> to <vlan-id> parameters specify a contiguous range (a range with no gaps) of individual VLAN IDs. Specify the low VLAN ID first and the high VLAN ID second. The command adds all of the specified VLANs to the VLAN group.

You can add up to 256 VLANs with the command at one time. To add more than 256 VLANs, enter separate commands. For example, to configure VLAN group 1 and add 512 VLANs to the group, enter the following commands.

Brocade(config)# vlan group 1 vlan 2 to 257

Brocade(config-vlan-group-1)# add vlan 258 to 513

Thanks

Michael.

Hi chipitsine,

     Did you get a chance to test this out to see if it meets your reuirements?

Thanks

Michael.
