Salve como o nome de UFRGS-MIB.txt e copie para /usr/share/snmp/mibs
Verifique se esta correto:
# snmptranslate -m +UFRGS-MIB -IR ufrgs
Instale o mib2c:
# cd ~/net-snmp
# cd perl
# cd default_store
# perl Makefile.PL
# make
# make install
# cd ..
# cd SNMP
# perl Makefile.PL
# make
# make install
Então vá para o diretório de instalação net-snmp/agent/mibgroup e execute:
# env MIBS=”+UFRGS-MIB” mib2c -c ../../local/mib2c.scalar.conf ufrgs
Recompile o snmp com suporte ao MIB ufrgs:
# cd ~/net-snmp
#./configure –prefix=/usr –sysconfdir=/etc –with-mib-modules=ufrgs
Acender o primeiro LED:
# snmpset -c led -v 1 -m +UFRGS-MIB 10.1.240.246 led0.0 i 1
ou
# snmpset -c led -v 1 10.1.240.246 1.3.6.1.4.1.9362.1.1.0 i 1
Apagar o primeiro LED:
# snmpset -c led -v 1 -m +UFRGS-MIB 10.1.240.246 led0.0 i 0
ou
# snmpset -c led -v 1 10.1.240.246 1.3.6.1.4.1.9362.1.1.0 i 0
