Host_id is a counter used internally to mean a particular host. The
first host gets number 1, next is 2 etc

The code looks like it would give a syntax error. I don't think or
at least I do not recommend you can assign into a switch.
The switch is saying if host_id is 10, 11 or 12. You've hard-coded the
id into the code. OK for you but a bad idea in general.
Perhaps
if ($host_id == 10 || $host_id == 11 || $host_id == 12) {
$ifDescr = snmp_walk("$ip","$rocommunity",".1.3.6.1.2.1.2.2.1.1");
} else {
$ifDescr = snmp_walk("$ip","$rocommunity",".1.3.6.1.2.1.2.2.1.2");
}
Syntactically correct, but still not ideal. Let's rephrase what you
are trying to do.
"For a particular type of device, use a different interface description"
In the SNMP world Type of device -> the sysObjectID
So go get the system.sysObjectID.0 object, or snmpwalk system
to get it, it will be something like:
.1.3.6.4.1.1.1872.1.6
It *will* be different from 1872 onwards, unless you are doing this on
an Alteon AD3.
So get the sysobjectid and check that
$sysobjid = snmp_get($ip, $rocommunity, '.1.3.6.1.2.1.1.2.0');
if ($sysobjid == 'your oid goes here') {
$ifDescr = snmp_walk("$ip","$rocommunity",".1.3.6.1.2.1.2.2.1.1");
} else {
$ifDescr = snmp_walk("$ip","$rocommunity",".1.3.6.1.2.1.2.2.1.2");
}
Then, as long as the system object id stays the same (or you check for
multiple oids) any device of that type will be handled that way.
