jnxJsScreenSynFloodDstThresh

Module: JUNIPER-JS-SCREENING-MIB

OID (symbolic): JUNIPER-JS-SCREENING-MIB::jnxJsScreenSynFloodDstThresh

OID (numeric): 1.3.6.1.4.1.2636.3.39.1.8.1.1.2.1.2

Node type: OBJECT-TYPE

Type: Integer32

Access: read-only

Description: The number of SYN segments received per second from a single destination IP address before the security device begins dropping connection requests to that destination. If a protected host runs multiple services, you might want to set a threshold based on destination IP address only - regardless of the destination port number.

What is jnxJsScreenSynFloodDstThresh?

This read-only value reports the configured per-destination SYN-flood threshold: the number of SYN segments per second to one destination IP, regardless of port, before the device starts dropping requests to that destination - useful when a protected host runs multiple services. An admin reads this to confirm the destination-based SYN-flood defense is tuned appropriately for a given protected server.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.2636.3.39.1.8.1.1.2.1.2
snmpwalk -v2c -c public <target> JUNIPER-JS-SCREENING-MIB::jnxJsScreenSynFloodDstThresh

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.2636.3.39.1.8.1.1.2.1.2.1
snmpget -v2c -c public <target> JUNIPER-JS-SCREENING-MIB::jnxJsScreenSynFloodDstThresh.1
