the value of ifOperStatus doesn't reflect the real status of the interface

Hi, 

 

I compile MIB-II mib module into net-snmp agent (netsnmp of version 5.2, compiling for linux-2.4.18, powerppc). I found that the value of ifOperStatus for the ppp interface doesn�t reflect the real status of the interface. ifOperStatus is always �down� even that the interface is up.

 

The following is the related info by ifconfig

 

ppp0      Link encap:Point-to-Point Protocol

          inet addr:10.7.4.1  P-t-P:10.7.4.2  Mask:255.255.255.255

          UP POINTOPOINT RUNNING NOARP MULTICAST  MTU:1500  Metric:1

          RX packets:10279 errors:1 dropped:0 overruns:0 frame:0

          TX packets:10312 errors:0 dropped:0 overruns:0 carrier:0

          collisions:0 txqueuelen:3

          RX bytes:955661 (933.2 KiB)  TX bytes:958702 (936.2 KiB)

 

 

The corresponding mibii-interface info are the following

ifIndex.3            3

ifDescr.3           pp0

ifType.3             23 (ppp)

ifMtu.3              1500

ifSpeed.3           0

ifAdminStatus.3             1(up)     

ifOperStatus.3               2(down)

ifInOctets.3                    968123

ifInUcastPkts.3              10413

ifInDiscards.3                 0

ifInErrors.3                     1

ifOutOctets.3     971722

ifOutDiscards.3              0

ifOutErrors.3                  0

ifOutQLen.3                   0          

 

Both ethernet interface and loopback are OK. However, the agent can�t send out linkUpDown traps. (I compile disman-event mib into the agent and include linkUpDownNotifaction yes into snmpd.conf).

 

Any advices are suggestions very appreciated!

 

Regards,

 

Jennifer
