Configuring Super Aggregated Vlans - HP ProCurve 9304M Installation And Configuration Manual

Installation and Basic Configuration Guide
2. Select the Max-Parameter link to display the Configure System Parameter Maximum Value table. This table
lists the settings and valid ranges for all the configurable table sizes on the device.
3. Click the Modify button next to the row for the parameter (in this case, "vlan").
4. Enter the new value for the table size. The value you enter specifies the maximum number of entries the
table can hold.
5. Click Apply to save the changes to the device's running-config.
6. Select the Save link at the bottom of the dialog. Select Yes when prompted to save the configuration change
to the startup-config file on the device's flash memory.
7. Click on the plus sign next to Command in the tree view to list the command options.
8. Select the Reload link and select Yes when the Web management interface asks you whether you really want
to reload the software. Changes to cache and table sizes do not take effect until you reload the software.
Increasing the Number of Virtual Routing Interfaces You Can Configure
To increase the size of the virtual routing interface table, which determines how many virtual routing interfaces you
can configure, use either of the following methods.
USING THE CLI
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:
HP9300(config)# system-max virtual-interface 4095
HP9300(config)# write memory
HP9300(config)# end
HP9300# 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. See .
USING THE WEB MANAGEMENT INTERFACE
See the Web management procedure for increasing the VLAN table size, in "Increasing the Number of VLANs You
Can Configure" on page 11-41.

Configuring Super Aggregated VLANs

You can aggregate multiple VLANs within another VLAN. This feature allows you to construct Layer 2 paths and
channels. This feature is particularly useful for Virtual Private Network (VPN) applications in which you need to
provide a private, dedicated Ethernet connection for an individual client to transparently reach its sub-net across
multiple networks.
A path contains multiple channels, each of which is a dedicated circuit between two end points. The two devices
at the end points of the channel appear to each other to be directly attached. The network that connects them is
transparent to the two devices.
You can aggregate up to 4094 VLANs within another VLAN. This provides a total VLAN capacity on one HP
device of 16,760,836 channels (4094 * 4094).
The devices connected through the channel are not visible to devices in other channels. Therefore, each client
has a private link to the other side of the channel.
The feature allows point-to-point and point-to-multipoint connections.
Figure 11.16 shows a conceptual picture of the service that aggregated VLANs provide. Aggregated VLANs
provide a path for multiple client channels. The channels do not receive traffic from other channels. Thus, each
channel is a private link.
