rsIpAdEntForwardIpBroadcast
Module: CISCOSB-IP
OID (symbolic): CISCOSB-IP::rsIpAdEntForwardIpBroadcast
OID (numeric): 1.3.6.1.4.1.9.6.1.101.26.1.1.4
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This variable controls forwarding of IP (sub)net-directed broadcasts destined for an attached sub(net).
What is rsIpAdEntForwardIpBroadcast?
This read-write value controls whether the device forwards IP subnet-directed broadcasts destined for the attached subnet. Admins disable this as a security hardening measure to prevent the device from being used to amplify or relay broadcast-based attacks onto the local subnet. For example, setting this to disable would stop the device from forwarding a directed broadcast packet aimed at that subnet's broadcast address, blocking a common vector for broadcast amplification.
