[ixpmanager] Interface Polling issue - MauType error

Tue Mar 10 21:50:06 GMT 2015

Dear Barry et al,

first of all thanks for the good work and thanks for sharing the IXP Manager Tool. Great Stuff!

Unfortunately we ran into some problem while polling a Cisco 6509.

Polling process via the GUI gets interrupted with an error message „SNMP Error“

As we could not make up anything from this error message, we startet to dig a little deeper:

ERROR: OSS_SNMP exception polling sw001 by SNMP

Currently it looks like, that we get an error / unhanded exeption during the MauType Update, because of an empty or wrong return value from our switch.

dspierling at ixp1:/usr/local/ixp/library/OSS_SNMP.git/examples$ sudo ./mau.php sw001 public

Number of interfaces on sw001: 65

ID:  Name  - Index - Type - State - Media Available - Jack Type - State Exits - Jabber State - Autoneg

PHP Fatal error:  Uncaught exception 'OSS_SNMP\Exception' with message 'Could not perform walk for OID .1.3.6.1.2.1.26.2.1.1.4' in /usr/local/ixp/library/OSS_SNMP.git/src/OSS_SNMP/SNMP.php:277
Stack trace:

Looking further into this, it seems that this is confirming our assumptions; we do not receive any usable value for the OID „.1.3.6.1.2.1.26.2.1.1.4“ from the switch.

dspierling at ixp1:/usr/local/ixp/library/OSS_SNMP.git/examples$ snmpwalk -v 2c -c public sw001 .1.3.6.1.2.1.26.2.1.1.4
iso.3.6.1.2.1.26.2.1.1.4 = No Such Object available on this agent at this OID

Testing via snmpwalk - same result..

Any further information of our Interfaces seem to get polled accordingly:

dspierling at ixp1:/usr/local/ixp/library/OSS_SNMP.git/examples$ sudo ./interfaces.php sw001 public

3: Te1/3 - TenGigabitEthernet1/3 - ethernetCsmacd - down/down
4: Te1/4 - TenGigabitEthernet1/4 - ethernetCsmacd - down/down
etc…

Additionally here are some more information about the Cisco Switch:
