Field
Description
Request time out No response is received within the specified timeout period.
Sent = 3 Number of transmitted cells.
Received = 0 Number of received responses.
Lost = 3(100.00% loss)
Cell loss rate (percentage of the number of unresponded cells
to the total number of cells transmitted).
precedence
Use precedence to configure the priority of IP packets carried by the PVC of a PVC-group.
Use undo precedence to restore the default.
Syntax
precedence { min-number [ to max-number ] | default }
undo precedence
Default
No priority is configured for IP packets.
Views
PVC view in a PVC-group
Predefined user roles
network-admin
Parameters
min-number: Specifies the lowest priority of IP packets carried by the PVC, in the range of 0 to 7.
max-number: Specifies the highest priority of IP packets carried by the PVC, in the range of 0 to 7.
The max value must be equal to or larger than the min value.
default: Specifies the PVC as the default PVC. IP packets with priorities not specified for any PVC
are sent through the default PVC.
Usage guidelines
This command is applicable only to the PVCs in a PVC-group.
If no default PVC exists in a PVC group, IP packets with priorities not specified for any PVC are
distributed across all PVCs that are not configured with priorities on a per-packet basis.
If no PVC is specified as the default PVC and all PVCs are configured with transmission priorities, IP
packets with priorities not specified for any PVC are dropped.
This command cannot change the priority of an IP packet.
Examples
# Configure PVC aa with a VPI/VCI value of 1/32 to carry IP packets with priorities from 0 to 3.
