The Outgoing DLCI Priority value allows you to assign relative priority levels to
the DLCIs conÞgured on the selected physical port. The allowable range is 0-4,

Backup Group Number
Use this Þeld to specify whether this DLCI is a primary or a backup DLCI. If it is a
primary DLCI, enter the number (1-255) that identiÞes the Frame Relay Backup
Group that will take over if this DLCI fails. If it is a backup DLCI, enter 0. A DLCI
cannot be both a backup and a primary DLCI.

cannot be both a backup and a primary DLCI.
This parameter is applicable only on an initiating node, which is the node that
will initiate the switchover to a backup DLCI. At switchover, the initiating node
notiÞes the remote (non-initiating) node of the change. Do not conÞgure a Backup
Group Number on this DLCI at the remote (non-initiating) end.

Backup Protocol
This Þeld is only conÞgurable if the Backup Group Number is set to 0, indicating
that the DLCI being conÞgured is a backup DLCI. Set this Þeld to Enabled if this
DLCI will be used as a remote (non-initiating) backup. The DLCI will wait for a
backup protocol message from the initiating end, telling the backup where to
send the rest of the messages. Set this Þeld to Disabled if this DLCI is an initiating
backup.

State
Although it appears to be a settable parameter, the value displayed in the State
Þeld simply indicates the internal status of the entry you are conÞguring: active,
inactive, or invalid. The value displayed here indicates only the deviceÕs efforts to
add the entry to its MIB table.

NOTE
If you are conÞguring a primary DLCI, you must set this value to 0 until you have
conÞgured a Frame Relay Backup Group (see ConÞguring a Frame Relay Backup Group,

group.
