Hello

I have a problem with SNMP. I want to check the variable "sysUpTime" to know how many time my switch is up. But the server zabbix send to me this error:

OID [.1.3.6.1.2.1.1.3] value #2 has unknow type [81]


This is my config:



But, when use snmpwalk, i have a response:

ubuntu@ubuntu-desktop:~$ snmpwalk -v 2c -c public 10.56.144.252 1.3.6.1.2.1.1.3
DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (493079606) 57 days, 1:39:56.06


Please help me.
Thanks
