snmpwalk

[Remo Rickli]

I couldn't find in depth info anywhere else so...

I use PHP to query switches and routers in my network management
software (http://nedi.web.psi.ch).

PHP assign it's own indexes on a snmpwalk:

$ifip = snmpwalk("$_GET[ip]","$comm","1.3.6.1.2.1.4.20.1.1");

so $ifip[0] would be the first interface, but on the real device the
index starts with 1!
Using snmprealwalk("$_GET[ip]","$comm","1.3.6.1.2.1.4.20.1.1"); does
basically what I want, but adds "IF-MIB::ifIndex.". Since it's not even
numerical (like 1.3.6.1.2.1), I never know how much I'd have to substr etc.

Is there a way around this? Could an option be implemented to use real
indexes directly?

Hope this makes sense somehow...
