| Hello all, I'd like to monitor my ISDN backup lines, and would like to be notified when they come up. I have them setup right now as an "up dependency" on the WAN router connection. It's weird because I put the IP address in for the ISDN interface and I know the isdn isn't active but it still shows it as being up, I guess its routing the ping packets thru another interface and responding. Does anyone have any suggestions as to how to do this. I don't want a red alert all the time when the isdn connection is down, because its supposed to be down. thanks |

| | The only reliable way I've found to monitor when an ISDN connection is made is using syslog. If you're using a Cisco router, it will log an %ISDN-6-LAYER2UP message (assuming you're logging at level 6 or above) when it makes an ISDN connection. If you're forwarding your syslog messages to WhatsUp, you could set it up to watch for this message (and possibly the corresponding %ISDN-6-LAYER2DOWN message) to determine if the ISDN is connected or not. The drawback to this is that it's a passive monitor and not something that's actively being checked. |

| Jim, We had the same issue for our Dial Backup (Modem Connected to Aux Port). We worked around it by using the Interface SNMP Monitor. When DBU is not up, a Dormant condition exists (5 - Dormant), however, as you mentioned, we have "False" indications if it dials in and then changes to a 1 (1 - Active). Bummer... |

| Hi guys,
That's a very interesting topic.
I am a pretty new user of WhatsUp Pro and I did not add these ISDN backup links in my database but I reckon it would be a really interesting and nice feature to add.
Rather than using syslog events (passive monitors) like Jim (I don't mean that it's not a good idea though  , but it seems more complicated and not checked as often as a SNMP monitor would be), I would be more interested in using a SNMP supervision like RTroyKlein.
But what do you mean by "we have "False" indications if it dials in and then changes to a 1 (1 - Active)."
Don't you want to be alerted if the link is being used (switching from a down state to an up state?)
If anyone has advice or hints to give us about configuring the ISDN backup links in WUP, you are more than welcome  |

| We've done it on ours as a dependancy to check ip 10.10.1.2 (ISDN) only if 10.10.1.1 (ATM) is in a DOWN state.
