Configuring Aggregated Ethernet Minimum Links

On aggregated Ethernet interfaces, you can configure 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 configure the minimum number of links:

  1. Specify that you want to configure the aggregated Ethernet options.
    user@host# edit interfaces interface-name aggregated-ether-options
  2. Configure the minimum number of links.
    [edit interfaces interface-name aggregated-ether-options]user@host# set minimum-links number

On M120, M320, MX Series, T Series, and TX Matrix routers with Ethernet interfaces, the valid range for minimum-links number is 1 through 16. When the maximum value (16) is specified, all configured links of a bundle must be up for the bundle to be labeled up.

On all other routers, the range of valid values for minimum-links number is 1 through 8. When the maximum value (8) is specified, all configured links of a bundle must be up for the bundle to be labeled up.

If the number of links configured in an aggregated Ethernet interface is less than the minimum link value configured under the aggregated-ether-options statement, the configuration commit fails and an error message is displayed.
