If you get this error in zabbix autodiscovery function:
snmp_parse_oid(): cannot parse OID “IF-MIB::ifDescr”

Or if you just want to install MIBs for some other reason, do following:

1. install snmp-mibs-downloader – this will also automatcally download mibs:

root@server:~# apt-get install snmp-mibs-downloader

2. Comment following line in /etc/snmp/snmp.conf – to use default paths for mibs in snmp utils:

# As the snmp packages come without MIB files due to license reasons, loading
# of MIBs is disabled by default. If you added the MIBs you can reenable
# loading them by commenting out the following line.
#mibs :

3. In order to reload MIBs in zabbix, restart it:

root@server:~# service zabbix-server restart

And you are done!
