Cisco CMTS Configuration Commands
cable load-balance group threshold
To configure the threshold values that a load-balance group should use for load-balancing operations,
use the cable load-balance group threshold command in global configuration mode. To reset the load-
balance group to its default threshold values, use the no form of this command.
Syntax Description
n
load load-value
enforce threshold
load minimum number (Optional) Specifies that cable modems should be moved only if the load
stability percent
ugs band-value
OL-1581-08
cable load-balance group n threshold {load load-value [enforce threshold] |
load minimum number | stability percent | ugs band-value}
Specifies the number of the load-balance group. The valid range is 1 to 20.
Specifies the maximum load difference, as expressed in a percentage of
total load, that can exist between interfaces in a load-balance group before
the Cisco CMTS performs load balancing. If the load between interfaces is
greater than the value specified by load-value, cable modems that are
registering are assigned to the lesser-utilized interface until the load
difference is once again below this value. The valid range for load-value is
1 to 100 percent, with a default of 10 percent.
Note
(Optional) Enables dynamic load balancing, which moves online cable
modems after their initial registration to achieve load balancing of the cable
interfaces in a load-balance group. Cable modems that are currently online
are moved when the load difference between two interfaces in the load-
balance group exceeds this percentage. Modems continue to be moved until
the load difference falls below this value.
The possible valid range for threshold is 1 to 100 percent, but the threshold
must be equal to or greater than the percentage specified with the load-value
option. For this reason, the actual minimum for threshold is the current
setting of the load-value option. The default is also the same value as the
load-value parameter.
between the two interfaces is greater than the specified number of cable
modems or service flows (valid only when the method is the number of
modems or service flows). The valid range is 1 to 100, with a default of 5.
Specifies the threshold to be used to determine whether a channel or
interface is unstable, in terms of the percentage of successful ranging
requests. The percent value specifies the minimum percentage of successful
ranging requests that is acceptable; otherwise, the CMTS begins moving
CMs. The valid range is 1 to 100 percent, with a default of 50 percent.
Specifies that the Cisco CMTS should move cable modems with active UGS
service flows when the current UGS usage reaches the percentage of total
bandwidth available that is specified by the band-value parameter. The valid
range for band-value is 0 to 100 percent, with a default of 70 percent.
Note
The default of 10 percent is the minimum recommended threshold.
Do not set this threshold below 10 percent unless you have been
instructed to do so by Cisco TAC.
This option is effective only when the enforce option has also been
used to enable dynamic load balancing, and the Cisco CMTS has
been authorized to move cable modems with active UGS service
flows (using the
