Configuring Aggregated Ethernet Minimum Links
Related
Documentation
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 and on EX Series switches, other than EX8200 switches, 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.
On EX8200 switches, the range of valid values for minimum-links number is 1 through 12.
When the maximum value (12) 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.

Configuring Multicast Statistics Collection on Aggregated Ethernet Interfaces
122
T Series and TX Matrix routers support multicast statistics collection on aggregated
Ethernet interfaces in both ingress and egress directions. The multicast statistics
functionality can be configured on a physical interface thus enabling multicast accounting
for all the logical interfaces below the physical interface.
The multicast statistics information is displayed only when the interface is configured
with the multicast-statistics statement, which is not enabled by default.
Multicast statistics collection requires at least one logical interface is configured with
family inet or inet6; otherwise, the commit for multicast-statistics will fail.
