Figure	162. LMS IP Port Address Table Panel

This table allows you to view and/or modify the IP addresses assigned to each port.

The Multiprotocol Interconnect module allows you to configure up to five IP addresses for each LAN port. This is a useful feature that can be used in the following situations:

∙There are too many hosts on a LAN to be accommodated in a single IP subnetwork.

∙Two separate IP subnetworks have been bridged together and you want to use a single port on this module to route the traffic from these bridged networks.

You must take the following into consideration when assigning IP addresses to the ports:

∙

∙

∙

∙

∙

Only one port per subnetwork is allowed

The same IP address may not be assigned to more than one port

IP broadcast address may not be assigned to a port

If port does not have an IP address, IP routing cannot be enabled on that port

If no IP address is assigned to any of the ports, the IP routing function cannot be enabled at the module level

∙The Multiprotocol Interconnect module can send and receive BOOTP messages on a port with no configured IP address

5.Enable IP routing globally for the module. To do so, you must select IP system Parameters from the IP Menu.

Note: If you try to enable IP for the module, before assigning an IP address to at least one port, your request will be rejected.
