Default is 0. Specify the offset value for wfIpexSessionEntry
when instances for SVC are created. For example, when it is
set to 1023, instance ID for wfIpexSessionEntry for SVC
connections will be wfIpexSessionEntry.*.3.1024 and the next
one will be wfIpexSessionEntry.*.3.1025 and so on.
This MIB object is introduced not to assign same instance ID
to PVC and SVC when SVCs and PVCs are configured with single
circuit. Because wfIpexSessionEntry for PVCs are based on the
LCNs and the ones for SVCs are based on the order of each SVC
being created, there would be the cases that same instance IDs
are assigned to both SVC and PVC and it will cause the router
to fault. It needs to be set to the value which is greater
than the maximum LCN of the PVC connections when PVCs and SVCs
co-exist on a single circuit.
