 ===== Access via SNMP =====
-Please use SNMP v3 for accessing the router.
+Using SNMP v1/2c there are two communities. The "read" community only allows to read data. The "write" or "admin" gives read and write access. With "allowed hosts" you can restrict the SNMP access to the router via an IP range. "0.0.0.0" can be used for any access.
-First create a user (SYSTEM->Authentication->User accounts)"snmp" with the password "snmp01password".
+You can also use SNMP v3 for accessing the router.
 Attention must be paid to the fact that SNMP passwords have to be more than 8 characters long. Shorter passwords have to be doubled for SNMP (e.g. admin01 becomes admin01admin01).
+Only the user "admin" can be used
 To see the values run on linux: \\
 **snmpwalk -v 3 -u <user> -n "" -l authNoPriv -a MD5 -x DES -A <password>[<password>] <IPaddress>  1.3.6.1.4.1.31496.10.90**

+*if you use SNMP v1/2c with the MibBrowser please set either the "Community" (=read only) or the "Write Commuinity" (=read-write), but not both at the same time.
+For easier use please copy the NetModule private MIB (NETMODULE-VENDOR-MIB.mib into the MIB directory (e.g. C:\Program Files\MibBrowser Free Tool\mibs) and load it File->Load MIB .
