In regard to: Re: [OpenIndiana-discuss] arp response tuning for IP Source...:
Have you run any tcpdump / anything to check what exactly happens?
I tried 'sudo tcpdump arp', but whenever I run tcpdump, all I get is: tcpdump: unknown data link type 524288 Our network engineers indicated they could also analyze snoop output, so I instead ran sudo snoop -v -o /tmp/snoop-arp arp and captured a couple minutes worth of traffic. Our principal network engineer is looking at it now.
As far as I remember this feature does the following: It has a dhcp snooping database, which basicaly tracks all dhcp requests.
You're right that IP Source Guard originally relied on DHCP. That was one of the first things that our networking staff mentioned when they started explaining what they had done that was causing problems for my workstation & hipster VM. However, the latest iteration of IP Source Guard apparently now also has the ability to build its IP,MAC table from the results of the switch making periodic ARP requests. That's the method this switch was using, not the DHCP method. My workstation doesn't get its IPv4 or IPv6 addresses via DHCP; they're statically assigned. My hipster VM *does* get its address via DHCP.
