fddi ring health check

[AntiEarnie]

We are runing TCP/IP over a fddi ring. Does anyone know of a way to find out if a fddi ring has a break in it? Or how two figure out what devices the ring stops at? The hardware we are using will not allow telnet access so its not possible to just get the interface status. This one has me scratching my head. Even the hardware maker dosen't know of a way to get this info directly from the switch short of walking out to it and consoling up.

I used to have a version of this trouble with my FDDI ring, mine WAS telnetable and I could do SNMP to it (is your's SNMP capable?) but neither the telnet nor SNMP thought going from full to wraped was an error, so nothing ever warned you when the first cut was (which defeats a fair amount of needing two cuts for service to be impaired)

you don't give us a vendor or model number so beyond asking about SNMP I have no hints, just a comment that FDDI never did do what it promised for me

I tried to remain child-like, all I acheived was childish.

They are old DECSwitch 900EF's. About all they are doing is acting as gateways to put the local eathernet traffic on the fddi ring.

hints there IS SNMP support in them, it also references HUBwatch management system software which may do wwhat you want.

Jimbopalmer - After I consoled into one of the 900ef's I had sitting around I got then SNMP info. I've been playing with mrtg on and off isnce yesterday and it looks like I might be able to use that. At least it can grab info on the interfaces. Now I just have to try and set it up where I just get the status of the fddi interfaces.
