rcArpExtEntDoFlood
Module: RC-ARP-MIB
OID (symbolic): RC-ARP-MIB::rcArpExtEntDoFlood
OID (numeric): 1.3.6.1.4.1.2272.1.9.2.1.4
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: Enable or disable flooding of ARP responses for NLBS Virtual Mac on the specified interface.
What is rcArpExtEntDoFlood?
This read-write object enables or disables flooding of ARP responses for the NLBS Virtual MAC on the specified interface, defaulting to disabled. Admins enable it in load-balanced server environments where the virtual MAC's ARP response needs to be flooded across the segment rather than sent as a normal unicast reply, ensuring all switches learn the virtual MAC correctly. Setting rcArpExtEntDoFlood to enable(2) on an interface serving an NLBS cluster would flood that ARP response so every switch on the VLAN correctly learns the virtual MAC's location.
Examples
Walk all instances (SNMPv2c):
