4.7 SNMP Interface
The device can be accessed via SNMP over the Ethernet interface. The agent within the device is fully
SNMPv1-compatible and responds to GET, GETNEXT and SET commands. If SNMPv2 is used, the device
will also respond in SNMPv2 (including extended error codes). Traps are always v1.
SNMP communication usually uses UDP port 161, which is set as default, but can also be changed in M&C
INTERFACE SETTINGS within the front panel menu. Traps are sent over UDP port 162 as default, but have
to be enabled first and can only be configured via normal SNMP access.
On the SNMP manager side the basis for communication are the MIB files, whose structure is consistent with
the main menu structure of the corresponding device. In general, two MIB files are required. A global file
(WORK.MIB) contains the product tree of the company and all traps. Then each device has a specific MIB
file, which connects to the company tree and c
ontains the device’s menu structure. These MIB
-Files can be
requested through the support of WORK Microwave.
After a correct installation of the MIB files all further configurations can be made via SNMP. The
SystemConfig-node therefore contains an SNMP-subtree, which is not accessible through the front panel or
other remote communication protocols. In this subtree the community names for read and write access can
be changed (default is “public” for read and “private” for write). Further the complete trap co
nfiguration is
found here. Up to 4 trap receivers can be defined with an internal name, IP address, UDP port (default is
162), enable bit mask (default is 0 / set to 31 to enable all traps) and trap community name.
Compatibility remarks
SNMP on WORK Microwave devices has been developed mainly with iReasoning MIB Browser and has
been successfully tested on AdRem SNMP Manager, ServersCheck MIB Browser, KS-Soft MIB Browser and
NsaSoft FreeSNMP. Not all of these tools (especially KS-Soft MIB Browser) do understand SMIv2 correctly,
in which all MIBs of WORK Microwave are written. Further the included MIB compilers differ in how strict they
interpret the macro language (i.e. AdRem SNMP Manager is way more strict than the iReasoning browser).
Another point for consideration is the support of MIB-2. WORK Microwave devices do only support the sys-
tem subtree. As no further routing or network functionality is included, all other MIB-2 subtrees are omitted.
Checklist for getting started
The following points have to be considered on first time activation:
·
Does the IP address in your SNMP management software correspond with the IP address of the
agent?
·
Is the UDP port of both the agent and the mangement software set correctly? (default is 161)
·
Do the community names corresp
ond to the agent’s configuration? (default is “public” for read and “pr
i-
vate” for write access)
·
Is SNMP access enabled on the device? (only accessible via the front panel menu)
·
Trap reception: Is the trap receiver configured correctly? (Do not forget the enable bit mask!)
·
Trap reception: Can your PC be accessed over the trap UDP port? (See firewall settings!)
