jnxJsScreenMonIcmpFlood
Module: JUNIPER-JS-SCREENING-MIB
OID (symbolic): JUNIPER-JS-SCREENING-MIB::jnxJsScreenMonIcmpFlood
OID (numeric): 1.3.6.1.4.1.2636.3.39.1.8.1.1.1.1.9
Node type: OBJECT-TYPE
Type: Counter64
Access: read-only
Description: An ICMP flood typically occurs when ICMP echo requests overload its victim with so many requests that it expends all its resources responding until it can no longer process valid network traffic. With the ICMP flood protection feature enabled, and a threshold set. If the threshold exceeded, the system invokes the flood attack protection feature.
The default threshold value is 1000 packets per second. If the threshold is exceeded, the security device ignores further ICMP echo requests for the remainder of that second plus the next second as well.
This attribute records the ICMP flood attack packets.
What is jnxJsScreenMonIcmpFlood?
This read-only counter tallies ICMP flood attack packets caught in this zone, incrementing once the rate of ICMP echo requests exceeds the configured threshold (1000/sec by default), after which the device ignores further ICMP for the rest of that second plus the next. An admin uses a rising count here to confirm the ICMP-flood defense is actively engaging rather than letting the flood exhaust device resources.
