This read-write INTEGER (1..8) specifies the minimum number of transmit links required to be active for the IMA group to be in the Up state, and this value must be less than or equal to the maximum number of configured links in the group. An administrator tunes this as the transmit-side counterpart to axisImaGroupMinNumRxLinks, together defining how much link degradation the IMA port can tolerate before being declared down. For example, setting this to 6 on an 8-line group means the port stays Up transmitting as long as at least 6 of the 8 links remain active for sending.
