Configuration in the WBM
7.5.1.1
SNMP Agent
To enable SNMP agent on the managed switch, please check the SNMP
Enabled box and click [Submit] button as shown in Figure "SNMP Agent
Setting". The SNMP version 1 (V1), version 2c (V2c) and version 3 are supported
by WAGO's managed switches as summarized in "WBM Page, "Diagnostics" –
"SNMP" Tab, SNMP Agent Setting"Fehler! Verweisquelle konnte nicht
gefunden werden.. Basically, SNMP V1 and SNMP V2c have simple community
string based authentication protocol for their security mechanism, while SNMP V3
is improved with cryptographic security. The default setting of SNMP Version is
V3. The user can select SNMP Version by checking either the V1/V2c box and/or
the V3 box.

SNMP V1/V2c Community
SNMP V1 and SNMP V2c use a community string matching for authentication.
This authentication will allow network management software to access the
information or data objects defined by Management Information Bases (MIBs) on
the industrial managed switch. Note that this simple authentication is considered
a weak security mechanism. It is recommended to use SNMP V3, if possible.
There are two levels of authentications or permission type in WAGO 852-1322
and 852-1328, which are read-all-only or read-write-all. For example, in our
default setting as shown in Figure "SNMP V1/V2c Community Setting", an SNMP
agent, which is a network management software module residing on the
industrial managed switch, can access all objects with read-all-only permissions
using the string "public". Another setting example is that the string "private" has
permission of read-write-all.
