1. A method comprising:
- detecting, via a network device, a signal condition for a link aggregation group (LAG) link, where an associated LAG arranges multiple links, including the LAG link, into a logical port;
comparing, via the network device, the detected signal condition to a signal threshold range;
enabling, via the network device, one of a disabled state or a disabled timer state for the LAG link if the detected signal condition is outside the signal threshold range, where enabling, the one of the disabled state or the disabled timer state includes performing maintenance on the LAG link; and
ending the one of the disabled state or the disabled timer state in response to an earliest occurring one of;
completion of the maintenance, ora determination that none of the multiple links, in the LAG, is active.

Abstract
A device detects a signal condition for a link aggregation group (LAG) link, compares the detected signal condition to a signal threshold range, and enables one of a disabled state or a disabled timer state for the LAG link if the detected signal condition is outside the signal threshold range.

detecting, via a network device, a signal condition for a link aggregation group (LAG) link, where an associated LAG arranges multiple links, including the LAG link, into a logical port; comparing, via the network device, the detected signal condition to a signal threshold range; enabling, via the network device, one of a disabled state or a disabled timer state for the LAG link if the detected signal condition is outside the signal threshold range, where enabling, the one of the disabled state or the disabled timer state includes performing maintenance on the LAG link; and ending the one of the disabled state or the disabled timer state in response to an earliest occurring one of; completion of the maintenance, or a determination that none of the multiple links, in the LAG, is active. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16)

17. A device comprising:
-
a plurality of links; and a processor to; define a link aggregation group (LAG) from two or more of the plurality of links, where the LAG arranges two or more of the plurality of links into a logical port, detect a signal condition for a LAG link, of the two or more of the plurality of links in the LAG, compare the detected signal condition to a signal threshold range, enable one of a disabled state or a disabled timer state for the LAG link if the detected signal condition is outside the signal threshold range, where enabling, the one of the disabled state or the disabled timer state includes performing maintenance on the LAG link, and ending the one of the disabled state or the disabled timer state in response to an earliest occurring one of; completion of the maintenance, or a determination that none of the two or more of the plurality of links, in the LAG, is active. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)

25. A system comprising:
-
means for detecting a condition for a link aggregation group (LAG) link, where a LAG arranges multiple links, including the LAG link, into a logical port; means for comparing the detected condition to a threshold range; means for generating an alert for the LAG link if the detected condition is outside the threshold range; means for enabling one of a disabled state or a disabled timer state for the LAG link in response to the alert; means for performing maintenance on the LAG link while the LAG link is in one of the disabled state or the disabled timer state, where performing maintenance on the LAG link includes transmitting test traffic on the LAG link; and means for ending the one of the disabled state or the disabled timer state in response to an earliest occurring one of; an indication from the comparing means that the test condition for the test traffic is within the threshold range, completion of the maintenance, or a determination that none of the multiple links, in the LAG, is active.
