~SNMP Trapping.

[Skilldibop]

Looking into configuring a cisco 2650 connected to BT megastream with some sort of SNMP setup so that i can monitor the state of the Line and trigger alerts when it fails. It's a bit mission critical and it keeps blipping out for 30 seconds or so. For management reasons and BT nagging reasons i'd like SNMP alerts so i can get a log of when it went down and how many times etc. This can then be used to bully BT into fixing it properly.

Gimme fiber you tight fisted nobbeds.

Any suggestions as to the best way to approach this/ what software to use.

I use Ciscoworks for this kind of stuff and it sends me emails all the time... If you simply want to monitor whether the line is up or not, you could setup a syslog server and simply send logging traps to it, showing lineproto up/down messages..
If your getting tons of CRC errors or carrier transitions, you'll need something to poll the ifmib index on the interface to pick out the errors, problem is most snmp packages mostly do bandwidth/load not many allow you to specify specific mibs.. you'd be better off sending them screenshots of the interface output.

Well a simple prot up/down won't do cos the X.21 to the NTU is always fine, it's the bit between the NTUs that gays up.
Bandwidth would be ok as i could set it to tirgger when bandwidth hit 0. I.e there is no link there.
CRCs i get loads anyway cos the line quality is s*** and they won't put fibre at both ends cos of ofcom regs, which personally i think is cobblers and they won't do it cos they'd have to give us 2Mb lines as the fibre NTUs are 2meg native. Which is their fault for insisting they didn't need to do a site survey to upgrade from 256k to 1meg. Not my problem they signed a contract that they can't fulfil.

but yeah, would something like PRTG do the trick? or would it take something more complex than that?

You can convert mib files into PRTG but its a real pain, and a lot of the Cisco specific mibs don't work, fact is to do stuff like this you need a decent snmp management station capable of polling all the attributes, for example you can create a rmon alarm specific to a particular attribute of something on the router, for example if you start getting more than 10 CRCs per second it will flag and alarm and send it to the snmp management station, again problem is you need a decent snmp program.. you might be able to find something reasonably decent for free.
