Avaya P332G-ML manual Multinetting Multiple Subnets per Vlan, Router Configuration File

Chapter 1 Overview

destination IP address remains the limited broadcast address.

Multinetting (Multiple Subnets per VLAN)

In Router Mode, most applications such as RIP and OSPF, operate per IP interface. Other applications such as VRRP and DHCP/BOOTP Relay operate per VLAN. Configuration of these applications is done in the Interface mode. When there is only a single interface (subnet) per VLAN then system behavior is intuitive since a subnet and a VLAN are the same.

If the configuration includes multiple interfaces (subnets) per VLAN things start to get complicated.

For example, if there are two interfaces over the same VLAN and you configure DHCP server on one interface it will be used also for the second interface over the same VLAN. This behavior might be less expected and in some cases wrong.

In order to prevent misconfiguration and unexpected results, the P332G-ML prevents configuration of VLAN-oriented commands on an interface unless the user explicitly requested to using the new "enable vlan commands" CLI command.

Configuration of "enable vlan commands" on an interface overrides this configuration on other interfaces that belong on the same VLAN.

This ensures that VLAN-oriented commands can be configured from one interface only.

In case there is only one interface over a VLAN, then VLAN oriented commands for this VLAN can be configured through the single interface without the need to issue the "enable vlan command" command.

Note:

1.VLAN-oriented commands that were configured affect the VLAN of the interface that was used at the time the command was issued.

2.If the interface is moved to another VLAN (using the "ip vlan command") VLAN oriented configuration still relates to the original VLAN.

Router Configuration File

The Configuration File feature allows the user to read the P332G-ML routing configuration parameters and save them to a file on the station. The routing configuration commands in the file are in CLI format. The user can edit the file (if required) and re-configure the P332G-ML by downloading the configuration file. Although the file can be edited, it is recommended to keep changes to the file to a minimum. The recommended configuration method is using Avaya Multi-Service Network Manager P330 Device Manager and/or the CLI. Changes to the configuration file should be limited to those required to customize a configuration
