Hello,
We would like to extend functionality of ifAdminStatus on our platform which is
using net-snmp v5.7.3. The goal is to monitor a hardware register bit which
indicates whether the external power supply of the interface is enabled, and
report this bit via ifAdminStatus.1. We also want to set the h/w bit based upon
snmpset. The other interfaces (.2, .3, etc) should report ifAdminStatus as
usual.
What is the recommended way of integrating ifAdminStatus in this way? Does it
require source-code mods (interfaces.c), can it be implemented using the ‘pass’
extension with a script to read/write the h/w register as needed, or some other
approach? I've experimented with 'pass' scripts, but the down-side seems to be
that I have to implement not only ifAdminStatus.1 support, but also reporting
of ifAdminStatus.2 state, in order for 'getnext' to operate. Modifying source
has it's own pitfalls. What is the cleanest approach?
Thanks,
Alan
