1.8.2 Default Implementation
Without writing any instrumentation functions, we can compile the MIB and use the default implementation of it.
Recall that MIBs imported by "EX1-MIB.mib" must be present and compiled in the current directory ("./STANDARDMIB.bin","./RFC1213-MIB.bin") when compiling.
unix> erl -config ./sys
1> application:start(snmp).
ok
2> snmpc:compile("EX1-MIB").
No accessfunction for 'friendsTable', using default.
No accessfunction for 'myName', using default.
{ok, "EX1-MIB.bin"}
3> snmpa:load_mibs(snmp_master_agent, ["EX1-MIB"]).
ok
