Hello, I'm testing a fault scenario where the recovery operation of a device attached to the network changes the link layer address corresponding to its IP address. The device is not sending gratuitous ARPs when this operation occurs.
By default, the Solaris operating system refreshes its arp cache every 1200000ms (20 minutes). Due to this large arp cache refresh interval, the Solaris gets the new link layer address of the device after 20 minutes. That means the Solaris will look for the old link layer address of the failover IP until its arp cache gets updated. I plan to lower the ip_ire_arp_interval to 1 minute. Is that sufficient or does the arp_cleanup_interval also need to be lowered? Also, can either of these parameters be set in /etc/system or does a startup script need to be added that uses ndd(1m)? -David _______________________________________________ networking-discuss mailing list [email protected]
