how to set ifadminStatus=down on unused NIC (HP-UX 11i-v1)

[Antonio Cardoso_1]

I've some unused NICs on a rp4440, and found no way to set the ifAdminStatus=down on them.
- ifconfig down doesn't make it
- SAM disable NIC also not.

Any way to do it?

thanks.

Hi Antonio,

Is your server in run-level 3?

Could please post the complete commands you used?

Please also post the output of

# lanscan

# ioscan -fnClan

regards,
Robert-Jan

Yes, run-level is 3:
# who -r
. run-level 3 Apr 10 18:38 3 0 S

Antonio,

Why do you care that adminstatus is up?

I wouldn't normally worry about this.

ifconfig is an IP level tool, not a physical interface level tool, so the most you can do there is tear down the IP stack on the interface with:

ifconfig lanX unplumb

obviously replacing lanX with a specific interface.

I suspect the disable interface function in SAM just does that as well.

Hi,

# ifconfig lan3 0.0.0.0

# ifconfig lan3 unplumb

# ifconfig lan4 0.0.0.0

# ifconfig lan4 unplumb

All,
I'm looking at this status, because monitoring ifTable to generate some alarms, and I want to ignore administratively locked interfaces.

I get:
interfaces.ifTable.ifEntry.ifAdminStatus.1 = up(1)
interfaces.ifTable.ifEntry.ifAdminStatus.2 = up(1)
interfaces.ifTable.ifEntry.ifAdminStatus.3 = up(1)
interfaces.ifTable.ifEntry.ifAdminStatus.4 = up(1)
interfaces.ifTable.ifEntry.ifAdminStatus.5 = up(1)
interfaces.ifTable.ifEntry.ifAdminStatus.6 = up(1)
interfaces.ifTable.ifEntry.ifOperStatus.1 = up(1)
interfaces.ifTable.ifEntry.ifOperStatus.2 = up(1)
interfaces.ifTable.ifEntry.ifOperStatus.3 = up(1)
interfaces.ifTable.ifEntry.ifOperStatus.4 = down(2)
interfaces.ifTable.ifEntry.ifOperStatus.5 = down(2)
interfaces.ifTable.ifEntry.ifOperStatus.6 = up(1)

Antonio,

So you're using some sort of SNMP tool to collect the info?

If that's the case you should be able to just use a snmpset to set ifAdmin to DOWN (as long as you have a suitable set community name defined in snmpd.conf)
