• upstream — assigns a port or port-channel to the uplink-state group as an upstream interface.
• uplink-state-group — creates an uplink-state group and enables the tracking of upstream links.
downstream disable links
Configure the number of downstream links in the uplink-state group that are disabled if one upstream link in an uplink-state group goes
down.
Syntax
downstream disable links {number |all}
To revert to the default setting, use the no downstream disable links command.
Parameters
number Enter the number of downstream links to be brought down by UFD. The range is from 1

Version Description
8.3.16.1 Introduced on the MXL 10/40GbE Switch IO Module.
Usage Information
A user-configurable number of downstream interfaces in an uplink-state group are put into a link-down state with
an UFD-Disabled error message when one upstream interface in an uplink-state group goes down.
If all upstream interfaces in an uplink-state group go down, all downstream interfaces in the same uplink-state
group are put into a link-down state.

• upstream — assigns a port or port-channel to the uplink-state group as an upstream interface.
