Hi: We're trying to add a tagged vlan network to our management (non-default) network to use for backups. We're having problems with traffic on the tagged network stopping after some time. The interesting thing is that the network always fails exactly on the hour. Traffic any of the untagged interfaces is unaffected.
The network starts working again when an arp is received. I started out working with Sun on this before we determined that the issue seemed to lie with pfil. The Sun engineer said: The ire_cache gets purged every 40min. This means every 3 purges are at the top of the hour. The time difference between when opal pings heliodor (seq# 0x36e0/14048) and when heliodor replies (0x400b/16395) is about about 40 minutes also. The problem happens if ipfilter is loaded or not. We're running: SunOS opal.usg.tufts.edu 5.9 Generic_122300-07 sun4u sparc SUNW,Sun-Fire-V210 ipfilter: 4.1.28 pfil: 2.1.13 We've got system cores from the systems when they're broken that I'm happy to pass along. We really don't need ipfilter/pfil on the backup vlan. Can I keep pfil from loading on the interface by removing it from /etc/opt/pfil/iu.ap ? Thanks! -j
