FRM Conf iguring Frame Relay 7-19
received (sequentially) without BECN set, the effective outgoing B
E
will be increased
by 1/8 of the configured value.
As long as no BECNs are received, the effective burst size will continue to increase
until it reaches the full configured value. Any time a BECN is received, however, the
effective value will return to the value of the outgoing B
C
.
Outgoing DLCI Priority
sets a priority for this DLCI among others over the physical port. Note that 4 is the
highest priority.
Backup Group Number
specifies (if configured as any number other than 0 ) that this is a primary DLCI, and
identifies the backup DLCI(s) (see " Configuring Frame Relay Backup Groups " on
page 7-22) that will take over if this DLCI fails. 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 notifies the remote node of the change.
A DLCI cannot be both a backup and a primary.
Do not configure a Backup Group Number on this DLCI at the
remote (non-initiating) end.
Enable Backup Protocol?
specifies that (if Y ) this DLCI will be used as a 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.
Remote RLP/Port/DLCI
identifies the primary DLCI in the non-initiating (called "remote" for the purpose of
differentiating) node to which that this DLCI connects for normal operation. (A
remote RLP does not need to be configured if the remote device is another Smart-
Switch 1800 or an FRX4000.)
The primary and all of its backup DLCIs in a non-initiating
FRX6000/FRM must be on the same RLP.
Switchover Timer
is the time the initiating node will wait after detecting a primary DLCI failure before
it checks for available backups.
Switchback Timer
is the time the initiating node will wait before switching from the backup to the
primary DLCI after the primary becomes active again. If set to the maximum of
65565 ,
the backup will not switch to the primary unless it (the backup) fails.
