Minimum number of links per port-channel indicates the least number of links that need to be operationally UP in order to declare the port-channel as operationally UP. Users can provide an optional "min-link-count" per EFA port-channel during the PO create and PO update operations, which further gets configured on the SLX port-channel, .
Default value of min-link-count for a port-channel is 1, which is same as the SLX default value.
Update the min-link-count attribute value using min-link-count
operation.
Provide the PO “min-link-count” during PO create and PO update operations. EFA validates the po-member-port-count >= po-min-link-count per device
Note
During the upgrade from EFA 2.3.0 to EFA 2.4.0, the min-link-count for the port-channels is set to the default value 1.
Note
Single Homed to Dual Homed PO conversion is not allowed in EFA 2.4.0.
