Avaya X330WAN manual USP Port with PPP Encapsulation

You can not delete a PMI Layer 3 interface unless it is the last interface configured, or unless the PMI function is first assigned to another IP interface.

• Supporting an End point in Frame Relay Point to Multi-point Topology - X330WAN supports Point-to-Point Frame Relay connections. To enable you to use X330WAN as an end-point in a Point to Multi-Point (PTMP) topology, it supports Inverse ARP replies, and responds to Inverse ARP queries received on the Frame Relay Sub-interfaces with proper Inverse ARP replies.

When you connect X330WAN as an end-point in a Point to Multi-Point (PTMP) configuration, manually increase the OSPF timers to suit this topology using the ip ospf network point-to-multipointcommand from the Interface Serial context. This command increases the OSPF Hello and Dead Intervals to 30 and 120 seconds respectively.

•PMI (Primary Management Interface) - This is a unique Layer 3 interface that can be configured over any Layer 2 interface.

The PMI is the X330WAN management interface, through which the X330WAN’s management applications access the device. The PMI is used when downloading software or opening an Embedded Web session to X330WAN. In both cases, a route should exist between the TFTP server or the management station and the PMI IP address.

Note: The first IP interface created in X330WAN automatically becomes the PMI. It is recommended to configure the Loopback interface as the first Layer 2 interface and to configure an IP interface on it. After the PMI is configured, the following message appears:

The primary management interface has changed.

For this change to take effect, you need to copy running-config startup-config and then reset the device.

Enter the copy running-configstartup-configand reset commands at this stage.
