Hi,
i'm going to use zabbix for monitoring our network (cisco switches) by SNMP.

Zabbix run perfectly, i can see latest data and also i create some graphs.
It looks nice.

But in zabbix_server.log i see this error:
006835:20060118:093325 value #2 has unknow type [81]

There is a part of log:
...

The type is not defined in SNMP libs. May I ask you to figure out on what OID and type (numeris, string, etc) it fails? You may consider using snmpwalk.
