IBM SC30-3681-08 Restrictions for Spare Interfaces, Interface or add ATM LAN Emulation clients

	Using the CONFIG (Talk 6) Process
2.	Add a dial circuit using the add device command.
3.	Con®gure the spare interface by using thenet command to con®gure the
	interface or add ATM LAN Emulation clients.
4.	Con®gure the various protocols and features using theprotocol and feature
	commands.
5.	Exit the CONFIG process by pressing Ctrl-P.
6.	Access the GWCON process by entering talk 5.
7.	Bring the new interface online to the network using the activate command.

The following example shows how to con®gure and activate a new dial circuit on which the IP protocol is enabled. The dial circuit and IP protocol con®guration are not shown.

Example:

*talk 6

Restrictions for Spare Interfaces

The activate command cannot be used to activate a new interface on the network under the following conditions:

vYou have already entered a delete interface command. The device must be restarted if any interface has been deleted. You cannot delete a spare interface (indicated by null in list displays).

vThe spare interface is the only interface that enables a protocol or feature. The protocol or feature must already be enabled on an existing interface before it can be used by a spare interface.

vThe new spare interface has a header size or trailer size greater than the sizes for other interfaces.

vThere is not enough memory to allocate receive buffers for the new interface.

In these cases, you must restart the device to bring the new interface online.

You can con®gure the following interfaces as spare interfaces, but you cannot activate them on the network using the activate command:

vSDLC Relay

vPPP Multilink master and dedicated link nets

You must restart the device to bring these interfaces online.
