Low-level SNMP discovery with nonnumeric index

[hppt]

Hello!

There's a hardware and MIBs. MIBs imported in to Zabbix
SNMP have a table wcAccessPointTable and index for it - field with the MAC address (i.e. not a number)

snmpwalk outputs the following:

linux-zaa5:~ # snmpwalk-v 2c-c public 192.168.1.230 WC7520-MIB::wcAccessPointMac
WC7520-MIB::wcAccessPointMac.'. N.M.'.128 = STRING: 20:4e:7f:4d:9b:80
WC7520-MIB::wcAccessPointMac.'. .*T.'.64 = STRING: 20:e5:2a:54:9d:40
WC7520-MIB::wcAccessPointMac.'..!...'.0 = STRING: a0:21:b7:bd:18:0
WC7520-MIB::wcAccessPointMac.'..!...'.128 = STRING: a0:21:b7:bd:18:80
WC7520-MIB::wcAccessPointMac.'..!...'.0 = STRING: a0:21:b7:bd:19:0
WC7520-MIB::wcAccessPointMac.'..!...'.0 = STRING: a0:21:b7:bd:1c:0
WC7520-MIB::wcAccessPointMac.'..!...'.32 = STRING: a0:21:b7:bd:1c:20

And if you look using SNMP Browser these OID:

wcAccessPointMac.6.32.78.127.77.155.128
wcAccessPointMac.6.32.229.42.84.157.64
wcAccessPointMac.6.160.33.183.189.24.0
wcAccessPointMac.6.160.33.183.189.24.128
wcAccessPointMac.6.160.33.183.189.25.0
wcAccessPointMac.6.160.33.183.189.28.0
wcAccessPointMac.6.160.33.183.189.28.32

I.e. from somewhere takes 6, and after that there's a point MAC

Zabbix try to read wcAccessPointMac.'. N.M.'.128 and fails.

How to teach him to get a normal index? Or convert it

Hey,

I do LLD of F5's with SNMP and they have the same non-numeric OIDs.

I wrote a script which supports this. You can find it at https://www.zabbix.com/forum/showthread.php?t=45689

Let us know if you have any problems.
