   Hitachi HUS-VM SNMP setup


Network communication

Allow comunication between STOR2RRD server and the storage on CNTL IP and port 161 UDP
You can test network visibility through this test: 
perl /home/stor2rrd/stor2rrd/bin/conntest_udp.pl vspg_CNTL_host.example.com 162
  UDP connection to "vspg_CNTL_host.example.com" on port "161" is ok
