Revision as of 12:10, 26 October 2017

This function enables you to configure access over the SNMP protocol in versions 2 or 3.

With SNMP enabled, you receive a wealth of information (CPU usage, system load, memory info, ethernet traffic, running processes).
System location and system contact are only for your information. For example, when you connect from an SNMP client, you will see your location and name.

SNMP, version 3 has an encrypted transmission feature as well as authentication by username and password.
SNMP, version 2 does not have encrypted transmission, and authentication is done only via the community string.

The community string you set can contain up to 20 characters, while the password needs to have at least 8 characters.

Note:


Our storage system supports the SNMP protocol in MIB-II standard.  List of MIBs:

- mib-2.host
- mib-2.ip
- mib-2.tcp
- mib-2.udp
- mib-2.interfaces
- mib-2.at
- system

Examples:

NET-SNMP-EXTEND-MIB::nsExtendOutputFull."compression" = STRING: Pool-0/d1 1.00

Pool-0/z1@snap1 1.00

Pool-0/.sys 1.00

Pool-0/d1@snap2 1.00

Pool-0/z1 1.00

Pool-0 1.00

NET-SNMP-EXTEND-MIB::nsExtendOutputFull."volumes_list" = STRING: NAME USED AVAIL RATIO

Pool-0 4.13G 15.1G 1.00x

Pool-0/d1 96K 15.1G 1.00x

Pool-0/z1 56K 15.1G 1.00x

NET-SNMP-EXTEND-MIB::nsExtendOutputFull."snapshots_list" = STRING: NAME USED RATIO CREATION

Pool-0/d1@snap2 0B 1.00x Wed Oct 25 11:36 2017

Pool-0/z1@snap1 0B 1.00x Wed Oct 25 11:36 2017

Above example lists recently created snapshots.
