cfmFlowIpHopLimit
Module: CISCO-FLOW-MONITOR-MIB
OID (symbolic): CISCO-FLOW-MONITOR-MIB::cfmFlowIpHopLimit
OID (numeric): 1.3.6.1.4.1.9.9.692.1.2.5.1.7
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-only
Description:
This object indicates the hop limit of the corresponding traffic flow.
If version 4 of the IP carries the traffic flow, then the value of this column corresponds to the 'Time to Live' field of the IP header contained by packets in the traffic flow (as observed by the flow monitor).
If version 6 of the IP carries the traffic flow, then the value of this column corresponds to the 'Hop Limit' field of the IP header contained by packets in the traffic flow (as observed by the flow monitor).
The value of this column is valid only if the 'hopLimit' bit of the corresponding instance of cfmFlowIpValid is '1'.
What is cfmFlowIpHopLimit?
This OID records the hop limit (a counter that decreases as a packet passes through routers) from packets in a monitored data flow. Hop limit tells you how many routers a packet can still pass through before being discarded. A network analyst would review this to detect routing loops or understand how far packets traveled before reaching their destination.
