SNMP option
The SNMP adjustment is only available after the “SNMP“ option was enabled
(see chapter “Enabling of“).
In the first section, the SNMP functionality, including the sending of traps is
enabled or disabled with the “Mode“ selection field. With the selector “Version“
you can select the SNMP version (version 1, 2 or 3). In the two boxes below it, the
communities for versions 1 and 2 are given separately for reading and writing via
SNMP. With version 3, these two fields are disabled because all registered users
of the module (see menu “Passwords“) have the automatic read access to SNMP.
The write access can be enabled or disabled for each user by clicking the SNMP-
check box in the “Passwords“ menu.
By clicking the “MIB“ button the MIB of the module is generated and offered for
download.
In the second section the trap settings are done. First, the trap version is selec-
ted:
V1 trap - normal traps according SNMPv1 with specified community
V2 trap - normal traps according SNMPv2 with specified community
V2 inform - sends information traps according SNMPv2 and waits for an acknow-
ledgment
V3 trap - normal traps according SNMPv3
V3 inform - sends information traps according SNMPv3 and waits for an acknow-
ledgment
The community can be configured for traps of SNMP versions v1 and v2. User/
password and the using of the network MAC address as the engine ID can be
configured for traps of SNMP version v3. These settings must correspond with
the configuration of the trap receiver, so traps are successfully transferred. For
this purpose a test trap can be sent by clicking the button “Test“ to test the trans-
mission of traps. If a test trap triggered, all pre-preserved traps are discarded.
There up to 256 IP addresses to receive the traps can be created or enabled.
These are listed under “Receiver IP“. Below, the events can be configured,
whether and partly with what thresholds they should trigger traps. There are three
ways to configure a trap:
- without parameters, e.g. fan on/ off
- with a freely selectable parameter for a medium priority
- with a selectable parameter from a list for a medium priority
References and notes:
All users using SNMPv3 must use passwords with at least 8 characters. For SNMPv3 the SBL supports only the authentication
password, not the privacy password. The SBL only supports the MD5 algorithm for authentication password in SNMPv3.
Information traps are specific traps that are possible up to SNMPv2. If there is no acknowledgment of the receiver, the transmitter
attempts to transmit it later, until the confirmation is received.
A SBL module holds up to 256 information traps that could not be sent successfully. If there are more unconfirmed traps, the older
traps are discarded and noted in the logbook as having failed. A successful sent trap is also registered as such in the logbook. In
case of power failure or reboot of the module the non-confirmed traps are lost.
Details may be found in the help text for each event. The critical priorities are each covered with fixed values that can not be changed.
If the web site of QAMOS-IP module is open, no changes are possible via SNMP.
Passwords
Again, this setting appears only when you are logged in as administrator, having
the authority to make administrative changes. In addition the box “User and key-
word check“ in the submenu “GUI settings“ has to be clicked. The user ID and
password for the administrator can be set in the first line. The fixing of up to
8 user identification and passwords is possible. The limitations of user rights exist
only in the fact that they are not authorized to change web server settings, user
rights and password changes and default settings.
The default
password
for the
admin
is:
1111
and for the
user
s:
0000
If the SNMP option is enabled, to the right of each user appears an SNMP check
box. By clicking the box, the writing rights for individual users can be awarded for
the SNMP version 3 (see also section SNMP option).
