open-threshold
Sets the bandwidth threshold for bringing up a composite link.
Syntax: open-threshold value
no open threshold
value
Sets the bandwidth threshold for bringing up a composite link. Values are in Mb/second. If the value is set to zero (0), the composite link comes up when the first member-link comes up. If the value is set to n, the composite link comes up when the aggregate bandwidth of the member-links exceeds n.
Description: Composite links consist of sets of member-links. You can configure the composite link to open when the first member link opens, (open threshold value = 0), or when a the aggregate bandwidth provided by all the active links in the composite link rises above the open threshold.
NOTE The value configured by the open threshold command must be greater than the value configured by the close threshold command.
Use the open-threshold value command to set the open bandwidth threshold for the composite link. Values must be multiples of OC-3c available bandwidth. The following table lists the transmission rates and available bandwidths for the most widely used OC speeds:
For example, if the composite link consists of 4 OC-3c interfaces and 1 OC-12c interface, the maximum bandwidth for the composite link is (4 x 155.52) + (622.08) = 1244.16 Mb/sec.
Use the no open threshold command to set the open bandwidth threshold at the default value of 0. The composite link opens when the first member link becomes active.
Factory Default: 0.
Command Mode: Composite-link configuration.
Example: In the following example, the open-threshold command sets the threshold to open the composite link when the first member-link becomes active. The show interface composite-link command displays the new setting:
router(config)#interface composite-link Boston2LA
router(config-if)#open-threshold 0
router(config-if)#end
router#show interface composite-link Boston2LA
