(usr-tc) Crashing HiperARC
by ROC Services 27 Jan '01

27 Jan '01

OK, this is kind of odd. Got a HiperARC that's rebooting itself periodically. The card's been replaced already, flash has been upgraded to 5.1.99-8 (was acting up with 5.0.9 as well), and I've tried setting up a sniffer to see if anyone's throwing some sort of DoS attack at it (nothing showed up). Did get a crashdump, though. We've got a case open with 3Com, so I'm posting here in hopes that one of the more clueful 3Com techs will pick up on it. Support recommended replacing the HARC (did that), reflashing (did that), rebuilding the config (did that too), swapping power supplies (did that). They now say our power supplies aren't big enough, and we need to have 130 amp ones for this configuration. Possible, but I kind of doubt it, since they say that one 130 is sufficient, but we currently have two 70s, and removing either one of them and running the chassis on one makes no noticeable impact on the frequency of the crashes. Nothing interesting gets logged to syslog or RADIUS accounting, nor anything else of interest on the console before the crash dump shows up. Configuration is one ARC, 14 DSPs on PRI, dual 70A power supplies. Routing IP only, PAP/RADIUS authentication, OSPF. NMC and DSPs are at the required code versions for compatibity with 5.1.99 according to 3Com site, 2.1.9 across the board on DSPs, 8.0.9 on HiperNMC. This hub had been stable for months, and just started rebooting a few weeks ago. No configuration or firmware changes had been made to the ARC, although we have added a few more elements to the network it sits on, including one new OSPF speaking router. Looked over the config on that, and don't see anything that could be causing it to spew bad OSPF packets. One other thing I have noticed -- the past few times it's blown up, my RADIUS server logs an authentication request with no username received from the ARC. I don't know yet if this is a cause or a side-effect of the thing crashing, but I'm soon going to do some testing with throwing invalid LCP/PAP packets at it and see if I can provoke it into bombing.

RE: (usr-tc) configuring a second HiPer ARC
by Vance McIndoe 25 Jan '01

You'll get into all sorts of strife when both ARC's become available again - Lot's of address clashes I'd say. You'd have to manually clear all the calls that are using the "other" ip address pool. These could (would) be spread across all modem cards. Doesn't 5.1 HARC code have pool-priorities? -- Vance McIndoe InterConnect Ltd Phone: +64-4-494 1144 Fax: +64-4-494 1140 Mobile: +64-25-2477 608 Street: Level 2, Exchange Place, 5-7 Willeston Street, Wellington, New Zealand.
