When using the SNMP configuration, the command line used is:
where the Agent_ExtraOpts and Agent_ListenOn properties are inserted before " | |
| rocommunity | Read-only community name. The RediGate currently only supports read-only community, not read-write community. Enter a text string between 1 and 63 characters. |
| sysdescr | User-defined system description. Enter a text string between 1 and 127 characters. |
| syslocation | User-defined system location. Enter a text string between 1 and 127 characters. |
| syscontact | System contact of the individual who manages this system. Enter a text string between 1 and 127 characters. The following parameters are used as command-line arguments for the script which calls the snmpd service. Elecsys uses a standard Linux SNMP agent, and documentation on these properties can be obtained from public sources if extra options might be needed. |
| Agent_ExtraOpts | Extra command line options for the SNMP agent service may be entered here. Normally, this should be left blank. (Note, this field does not get added to the SNMP configuration file.) Text string must be 127 characters or less. If used, Agent_ExtraOpts should contain valid command options for 'snmpd', exactly as would be used in a Linux command line for starting the SNMP daemon. |
| Agent_ListenOn | This sets the port to listen for an SNMP management system connection. This option is added to the Linux command line. The default option, 'UDP:161' establishes a server on the standard UDP port 161 to use for SNMP. Multiple ports or protocols (such as TCP) can be added, separated by commas. For example the string 'UDP:161,5000,TCP:2000@localhost' would listen for SNMP on ports 161 and 5000 using UDP protocol, and using TCP protocol on localhost only at port 2000. |

If you need to use SNMP and it isn't working, contact Elecsys. You may need an additional firmware component to add to the RediGate.
SNMP v3
The SNMP configuration object can only be used with SNMP version 1 or 2c. If you need to use SNMP v3, the SNMP object should be omitted, and instead build the configuration file manually
1. Create the configuration file (such as /etc/snmpd.conf). For example:
sysdescr System description
syslocation System location
syscontact Contact name
rouser myuser priv
rwuser myadmin priv
createUser myuser SHA myuserpass DES myprivpass
createUser myadmin SHA myadminpass DES myadminprivpass
2. Create a Linux start script (such as /etc/init.d/S92snmpd), containing the snmpd start command. For example:
/sbin/snmpd -m RFC1213-MIB -M /usr/director/bin/mibs -C -c /etc/snmpd.conf UDP:1613. Test SNMPv3 with snmpwalk at the command line of the RediGate, such as:
snmpwalk -v 3 -u myuser -l authPriv -a SHA -A myuserpass -x DES -X myprivpass -M /usr/director/bin/mibs localhost
