Perform these steps to enable Hybrid Columnar Compression (HCC) on Direct NFS Client:

1. Ensure that SNMP is enabled on the ZFS storage server. For example:

   $ snmpget -v1 -c public server_name .1.3.6.1.4.1.42.2.225.1.4.2.0
   SNMPv2-SMI::enterprises.42.2.225.1.4.2.0 = STRING: "Sun Storage 7410"

2. If SNMP is enabled on an interface other than the NFS server, then configure oranfstab using the management parameter.
3. If SNMP is configured using a community string other than public, then configure oranfstab file using the community parameter.
4. Ensure that libnetsnmp.so is installed by checking if snmpget is available.
