accIpsecStatsTtlZeros
Module: ACC-IPSEC
OID (symbolic): ACC-IPSEC::accIpsecStatsTtlZeros
OID (numeric): 1.3.6.1.4.1.5.1.1.81.2.18
Node type: OBJECT-TYPE
Type: Counter
Access: read-only
Description: Number of packets dropped because the packet being tunneled had its TTL decremented to zero
What is accIpsecStatsTtlZeros?
ACC-IPSEC::accIpsecStatsTtlZeros counts packets that were dropped during tunnel processing because the Time-To-Live (TTL) field of the tunneled packet payload was decremented to zero before it could be re-transmitted at the far end. This counter helps identify routing loops or excessive hops in your network topology that are causing legitimate traffic to be discarded. For example, a value of 5 on a single-hop tunnel between two data centers suggests there is a routing loop somewhere, and you should review the BGP or static routing configuration.
