What is cisgIpsSgGlobalInDropPkts?
This Counter64 totals the packets dropped during receive processing across all currently and previously active Phase-1 control tunnels, per its description. A rising value here specifically (versus InPkts overall) points to control-plane processing problems - such as the device being overwhelmed, malformed packets, or a DoS-style flood of bogus IKE traffic - rather than normal negotiation activity. An admin seeing this counter spike alongside CPU or memory pressure on the router would suspect the device is struggling to keep up with incoming IKE traffic volume.
