RE: (usr-tc) configuring a second HiPer ARC
by Vance McIndoe 24 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.

(usr-tc) Half the modems on DSP hanging up just after connection
by zip-usrtc＠ran.zipcon.net 18 Jan '01

18 Jan '01

I'm having an odd problem where a DSP card is dropping connections directly after the negotiation process finishes, but only on modems 1-12. Modems 13-23 work fine. When I enable modems 1-12, they always drop connections immediately after modem negotiation completes. I get this syslog message: ============ A call, call id = 720898, has arrived on interface slot:1/mod:12 A call is established, call id 720898, on interface slot:1/mod:12 The connection for call id 720898, on if slot:1/mod:12 was dropped for user UNKNOWN ============ The DSP card is a replacement from 3Com for a card that failed. The first replacement they sent did not work at all. I think this may also be a bad card, but am looking for tips on things to try. I have already restored all setting from default, saved it to NVRAM and rebooted the card many times. The fact that it does correctly answer calls on modems 13-23 makes me think its defective. I went into the DSP card console and ran chdev tslot X cmd tooserv soft where X is 1-12. Once that was done, all is fine (expect the card only has 11 active modems). I also notice that I am getting these syslog messages over and over. GWCMDM_AL, slot:1/mod:24 TAPI OPEN failed GWCMDM_AL, slot:1/mod:24 TAPI_OPEN failed, retrying Thanks for any tips, Dan - To unsubscribe to usr-tc, send an email to "majordomo(a)xmission.com" with "unsubscribe usr-tc" in the body of the message.

Steve: Here is information I received from this list on how to set this up on 2 or more HiperARCs. On ARC-A you would type: set mpip client_state on set mpip server_state on set mpip client (IP of ARC-A) sharedsecret <Secret on ARC-A> set mpip client (IP of ARC-B) sharedsecret <Secret on ARC-B> set mpip server (IP of ARC-A) sharedsecret <Secret for ARC-A> set ntp primary_server <IP of NTP server> enable ntp save all On ARC-B you would type: set mpip client_state on set mpip server (IP of ARC-A) sharedsecret <Secret for ARC-B> set ntp primary_server <IP of NTP server> enable ntp save all > Set ARC-A as mpip client + server, plus set it to an NTP server (know of > any good ones?). You don't need to worry about IP addresses of the different ARCs. The ARC will tunnel between each other so it is invisible to the client. Hope this helps. I can't remember who originally came up with this, but it was helpful for me.
