Hi !
We have a 2.4.16 generic kernel and we run into troubles with arp. We have an ethernet segment of 600+ machines. On one of these machines, I have set up a static arp table by entering every mac-ip couple.
For several days, I have left the ARP learning (ifconfig eth0 arp) and there was no problem. Every 5 minutes, I have checked if there was learned address in the arp cache : there was none, so it didn't learn any new address.
Today, I have switch to a real static arp table (with ifconfig eth0 -arp). Randomly, some machines were then unable to ping the host.
After a "ifconfig eth0 arp ; ifconfig eth0 -arp", this some other machine which were unable to ping the host where the first machines are able to do it again. arp table is correct but randomly, some machines are unable to get their echo reply, even if its entry is in the arp table.
Are there known issues about large arp tables ? - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
