RV082 Detection of link down

    Using my RV082 in dual WAN mode. I'd like some way of being informed if one of the links has failed. I realise that I can go into the admin pages and look at the status etc but I'd like something that told me rather than me having to look for it.

    Had a look at the SNMP tree and even though some of the fields appear to indicate the status of the various LAN/WAN ports, they never seem to change even when the links are down.

    Don't mind what the solution is, as long as it let's me know.

    Any ideas?

    Thanks.

    Andy.

    I've got the same problem with the RV042. Even with WallWatcher installed, there's no report of of WAN link failures :p Looks like I'll be resorting back to this:
    http://www.techweb.com/winmag/fixes/2000/0818.htm -- and set it up to monitor both connections :p

    082 dual wan network service detection

    Hi

    I have a new 082, with the latest (Oct 2005) firmware and need help with getting NSD on dual wan to work.

    It works fine if I power off or remove the cables on either upstream adsl/dsl modem, but if I remove the cables from the modem to the wall socket, the 082 seems to think the WAN is still OK and doesn't switch.

    I've tried setting NSD to ping a known good host but the link still doesn't flip.

    Any clues? (I've been driven mad by so called support in the Philipines... anyone know a real Linksys support numner? - USA or UK?)

    TiA

    NSD detection

    Here's my settings, which seem to work fine. I'm on firmware 1.1.6.11

    Retry count: 3
    Retry timeout: 3
    When fail: Remove connection

    For both connections:

    Default gateway/ISP host/DNS lookup host - unchecked
    Remote host - checked. IP address 212.58.224.55 (BBC website)

    Hope that helps.

    Andy.

    If it's working correctly...

    You should see entries like this appearing in the syslogs / log viewer:

    Oct 3 11:55:36 2005 System Log SUSPEND : Remove ixp1 due to fail on Network Service Detection
    Oct 3 11:56:57 2005 System Log SUSPEND : Resume ixp1 due to success on Network Service Detection
    Oct 4 02:01:39 2005 System Log SUSPEND : Remove ixp2 due to fail on Network Service Detection
    Oct 4 02:01:42 2005 System Log SUSPEND : Resume ixp2 due to success on Network Service Detection

    Thanks for that, indeed, I have the same firmware as you - 1.1.6.11 and with your settings it works fine. (Maybe as I'd left the timeouts at 30 secs it was too high..?)

    No problem!

    Glad to be of help. I know how frustrating it can be when you know something should work but you can't find the 'magic' combination of setting to get it to that stage!

    Thanks morpheme. Had used a few brain cells on that as well.
