3.3.3
Configuring the Multi-Carrier ABC Minimum Bandwidth Override Option
A multi-carrier ABC group can be configured to be placed in Down state if the
group’s
capacity falls beneath a user-defined threshold.
By default, the Multi-Carrier ABC minimum bandwidth override option is disabled.
When enabled, the Multi-Carrier ABC group is automatically placed in a Down
state in the event that the group’s
aggregated capacity falls beneath the user-
configured threshold. The group is returned to an Up state when its aggregated
capacity goes above the threshold. An alarm is also raised:
•
Alarm ID
–
2201
•
Alarm Description
–
Multi Carrier ABC bandwidth is below the threshold
This option is used in conjunction with the LAG group shutdown in case of
degradation event option (see
Enabling and Disabling LAG Group Shutdown in
) in cases where the operator wants to re-route traffic
from an upstream switch connected to an another IP-20 unit whenever the link is
providing less than a certain capacity. To set up a configuration in which a drop in
the capacity of the Multi-Carrier ABC group closes the Ethernet port in the
upstream FibeAir IP-20 unit, you must perform all of the following steps:
•
Enable the Multi-Carrier ABC minimum bandwidth option and set a threshold
on the IP-20C or IP-20C-HP unit, as described below.
•
Enable an ASP group on the IP-20C or IP-20C-HP unit, where the Monitored
Interface is the Multi-Carrier ABC group and the Controlled Interface is the
Ethernet interface that faces the upstream IP-20 unit. See
•
Enable the LAG group shutdown in case of degradation event option on the
upstream IP-20 unit.
Notes:
When using in-band management, management is lost in the event of
radio failure and returns when the radio link is restored.
