lcArpSpoofingProtection
Module: LANCITY-MCNS-MIB
OID (symbolic): LANCITY-MCNS-MIB::lcArpSpoofingProtection
OID (numeric): 1.3.6.1.4.1.482.60.5.5.4
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: Controls ARP Spoofing Protection on the CMTS when it is in layer-3 switching mode (Mode B). CMTS must be in MODE B for ARP Spoofing Protection to work. If set to enable(1), the CMTS will not forward or glean information from ARP packets received from the Cable interface whose sender's IP address does not match the IP address for the sender's hardware address as learned from DHCP gleaning. If set to disable(2), the CMTS will forward the ARP packet and will update its ARP cache with the IP address in the ARP.
What is lcArpSpoofingProtection?
Read-write switch, enable(1) or disable(2), for ARP spoofing protection while the CMTS is in Layer-3 switching (Mode B/DHCP-ARP) forwarding; when enabled, the CMTS drops or refuses to learn from cable-side ARP packets whose claimed IP doesn't match what DHCP gleaning learned for that MAC. Requires Mode B to have any effect.
