R2511-HP MSR Router Series Voice Command Reference(V5)

326
cid select-mode
Use cid select-mode to configure the CID selection mode which the originating side of a VoFR call
adopts.
Use undo cid select-mode to restore the default.
Syntax
cid select-mode { max-poll | min-poll }
undo cid select-mode
Default
CIDs are cyclically selected in descending order.
Views
Interface DLCI view
Default command level
2: System level
Parameters
max-poll: Selects circuit IDs cyclically in descending order.
min-poll: Selects circuit IDs cyclically in ascending order.
Usage guidelines
In the dynamic mode, it is possible that multiple voice channels share one DLCI. The same CID at both
ends will lead to a call collision. To prevent call collisions, configure different CID selection modes at both
ends.
Examples
# Set the CID selection mode to min-poll on DLCI 100.
<Sysname> system-view
[Sysname] interface serial 1/0
[Sysname-Serial1/0] fr dlci 100
[Sysname-fr-dlci-100] cid select-mode min-poll
