What is usdSmdsMajorIfStatsInKeepaliveReplies?

This read-only Counter32 tallies the number of keepalive replies the SMDS major interface has received in response to its own keepalive requests. A healthy, steadily incrementing value confirms the remote peer is responsive. An admin would compare this counter against usdSmdsMajorIfStatsOutKeepaliveRequests to spot a peer that stopped replying.
