Type: INTEGER
Access: read-write
Description: This attribute specifies the method to be used by the IMA group when selecting links to be activated. This comes into effect only when the configured links do not respect the maximum differential delay (otherwise all links are accepted).
If leastDelay is chosen, first the link having the smallest delay is selected as the reference link. The IMA group includes all links which respect the maximum differential delay relative to the reference link.
If maxBandwidth is chosen, the IMA group selects the maximum possible number of links, with each selected link respecting the maximum differential delay relative to every other selected link. When more than one possibility exists, the combination which offers the least delay isselected.
The default value for Multi-Service Access cards is leastDelay, and for all other cards is maxBandwidth. On Multi-Service Access cards leastDelay is the only acceptable provisionable value.
What is mscLpImaLinkSelectionCriterion?
This chooses how the IMA group picks which configured links to actually activate when not all of them meet the maximum differential delay: leastDelay picks the lowest-delay link as reference and adds any link within tolerance of it, while maxBandwidth instead maximizes the number of active links (breaking ties by least delay). An admin on a Multi-Service Access card is restricted to leastDelay, while other card types default to maxBandwidth, so this is one of the first things to check when an IMA group isn't activating all its provisioned links.
