Description: Number of packets dropped because the authenticator length was not supported
What is accIpsecStatsUnsuppAHLens?
ACC-IPSEC::accIpsecStatsUnsuppAHLens counts incoming packets that were dropped because the Authentication Header (AH) length was not supported by the device—often due to hardware limitations or older firmware that doesn't handle certain hash algorithm output sizes. This is rare with modern devices, but you might see it if you're connecting to legacy equipment that uses an uncommon AH algorithm. For example, a value of 3 might indicate the peer device is using a 96-bit authenticator length that your older gateway doesn't support.
