Description
Current load usage for the cable interface, expressed as a percentage of the total bandwidth.
For upstreams, this field shows a single percentage value, which shows the average percentage
of bandwidth being used on that upstream.
For downstreams, this field shows a set of three percentage values:
The first percentage shows the load usage for the entire interface.
•
The second percentage (within the parentheses) shows the load for the downstream.
•
•
The third percentage (within the parentheses) shows the average load for all upstreams on
this downstream.
For example, if this field shows "
upstreams on the interface are running at an average load of 18 percent, the downstream itself
is running at an average load of 18 percent, and all upstreams for this downstream are running
at an average load of 12 percent.
This field is a long-term average of the upstream utilization. To display a short-term

average of the utilization, use the
Current state of the cable interface, as it affects load balancing operations. The following
indicate normal operational states, depending on the configuration:
down—Interface is administratively shut down. The CMTS does not use the interface for
•
load balancing.
initial—Interface is currently in the initialization phase. The CMTS will use the interface
•
for load balancing after the initialization completes.
up—Interface is administratively up and should be passing traffic. The CMTS is actively
•
using the interface for load balancing.
testing—Interface is currently under a load-balancing test. The CMTS will not use the
•
interface for normal load balancing operations until the test completes.
The following states indicate abnormal states. The CMTS is not using interfaces in these states
for load balancing operations, but continues to monitor them and update their status every time
the CMTS polls the interfaces for their current load usage:
suspicious—Interface is in an unknown state. The interface might be up and passing
•
traffic, but is not consistent enough to include in load balancing operations. The CMTS
attempts to reinitialize the interface after a timeout period. If that fails, the CMTS moves
the interface to the unstable state if the maximum number of retries (10) has not been
exhausted. If the interface has failed initialization more than 10 times, the CMTS marks it
as disabled.
disabled—Interface has been disabled because a load-balancing test is occurring or
•
because the interface could not be initialized after 10 attempts. If a test is not occurring
and the interface can still not be initialized, the CMTS marks the interface as unstable.
unstable—Interface has failed repeated initialization attempts. The CMTS will attempt to
•
reinitialize the interface after a timeout period.
