fdryIpSrcGuardIfEnable
Module: FDRY-IP-SOURCE-GUARD-MIB
OID (symbolic): FDRY-IP-SOURCE-GUARD-MIB::fdryIpSrcGuardIfEnable
OID (numeric): 1.3.6.1.4.1.1991.1.1.3.37.1.1.1.1
Node type: OBJECT-TYPE
Type: TruthValue
Access: read-write
Description: This object indicates whether IP Source Guard is enabled at this interface. If this object is set to 'true', IP Source Guard is enabled. Traffic coming to this interface will be forwarded. If it is from the list of IP addresses obtained from DHCP snooping. Otherwise it is denied. If this object is set to 'false', IP Source Guard is disabled.
What is fdryIpSrcGuardIfEnable?
This true/false value enables or disables IP Source Guard on this interface: when true, only traffic from IP addresses learned via DHCP snooping is forwarded, while unlisted traffic is denied. An admin enables it on untrusted access ports to block IP spoofing from unauthorized devices. For example, enabling this on a customer-facing port would drop traffic from any host using an IP address it wasn't assigned through DHCP.
