Yes, that's an important topic too. There's a variety of access protocols that different devices support. Many devices have web interfaces. Some have snmp support. StarOS has that SSH interface. Another popularly supported interface is plain telnet. In a network composed of mixed equipment odds are you won't find a single access protocol common to all devices. It's good to use tools that support multiple access protocols so you can interrogate a variety of devices. MRTG is a popular tool, but it only does snmp to my knowledge, only does strip-graphs, and has limited programability for automation.
You mentioned working with MIBs. When dealing with MIBs, IMO it really helps to use a tool that loads the manufacturer's MIB definition files permitting you to reference MIBs by their natural name. I don't think anybody finds working with OIDs by number as fun (for example wanting to read "RSSI", but having to reference a string like "18.104.22.168.22.214.171.124.126.96.36.199.0"!). When you say Trango frequently changes their MIB definitions, hopefully you mean they constantly re-issue their MIB definitions files adding new parameters. Under no circumstances should any manufacturer CHANGE THE DEFINITION OF A PREVIOUSLY DEFINED OID. Any manufacturer that did this should be appropriately shamed! As long as they don't change definitions of previously defined OIDs (just add new ones), this is not a problem. Can you describe what Trango changes in their MIBs?

[ stuff ] For reference, in the network Scriv is describing, there's a nasty mixture of gear. Backhaul is primarily Trango (though that's likely to change at some point), and the customer APs are all either StarOS running on RouterBoard 200 hardware, or reallllly old Lucent APs with Karlnet software installed. StarOS doesn't export a lot of the data we're looking for, as far as I and my copy of snmpwalk can tell. (If I can read my boss's mind as well as I think I can, though, he's probably looking more for backhaul stats than for individual customer APs.) Trango supposedly does, but even their own forums are filled with people who can't make any sense out of Trango's provided MIBs and such. (I can usually get one-shot queries with snmpwalk and similar tools to work, but when you put the exact same parameters into an MRTG configuration file, I get back nothing but crazy bizarre errors. The fact that Trango changes their MIBs between hardware versions and occasionally even between firmware releases only compounds the problem.) At the risk of derailing (sorry, boss), has anyone gotten MRTG or something similar (PRTG, Denika, or whatever) to reliably track *anything* on a Trango? dave -- WISPA Wireless List: firstname.lastname@example.org Subscribe/Unsubscribe: http://lists.wispa.org/mailman/listinfo/wireless Archives: http://lists.wispa.org/pipermail/wireless/ -- WISPA Wireless List: email@example.com Subscribe/Unsubscribe: http://lists.wispa.org/mailman/listinfo/wireless Archives: http://lists.wispa.org/pipermail/wireless/
