jnxJsScreenMonUdpFlood
Module: JUNIPER-JS-SCREENING-MIB
OID (symbolic): JUNIPER-JS-SCREENING-MIB::jnxJsScreenMonUdpFlood
OID (numeric): 1.3.6.1.4.1.2636.3.39.1.8.1.1.1.1.10
Node type: OBJECT-TYPE
Type: Counter64
Access: read-only
Description: UDP flooding occurs when an attacker sends IP packets containing UDP datagrams with the purpose of slowing down the victim to the point that it can no longer handle valid connections. With the UDP flood protection feature enabled, a threshold can be set which once exceeded, the system invokes the UDP flood attack protection feature.
The default threshold value is 1000 packets per second. If the number of UDP datagrams from one or more sources to a single destination exceeds this threshold, security device ignores further UDP datagrams to that destination for the remainder of that second plus the next second as well.
This attribute records the UDP flood attack packets.
What is jnxJsScreenMonUdpFlood?
This read-only counter tallies UDP flood attack packets caught in this zone, incrementing once UDP datagrams to a single destination exceed the configured threshold (1000/sec by default), after which the device ignores further UDP to that destination for the rest of that second plus the next. An admin uses a rising count here to confirm the UDP-flood defense is actively engaging against a volumetric attack.
