On aggregated SONET/SDH interfaces, you can set the minimum number of links that must be up for the bundle as a whole to be labeled up. By default, only one link must be up for the bundle to be labeled up.
To set the minimum number, include the minimum-links statement at the [edit interfaces interface-name aggregated-sonet-options] hierarchy level:
- [edit interfaces interface-name aggregated-sonet-options]
-
minimum-links number;
The number can be from 1 through 8. The maximum number of links supported in an aggregate is eight or for Ethernet or SONET interfaces on a T-series platform or TX matrix routing platform, from 1 through 16. When 8 is specified, all configured links of a bundle must be up.
