4.6.1 SNMP
The agent communicates with the network management station via the
Simple Network Management Protocol. Therefore the network management
station uses the F network management software or the Web-based
interface.
Every SNMP packet contains the IP address of the sending computer and the
community under which the sender of the packet wants to access the switch
MIB.
The switch receives the SNMP packet and compares the IP address of the
sending computer and the community with the entries in the hmAuthCom
-
mTable and the hmAuthHostTable of its MIB. If the community has the
appropriate access right, and if the IP address of the sending computer has
been entered, then the switch will allow access.
In the delivery state, the switch is accessible via the "public" community (read
only) and the "private" one (read and write) from every computer.
To protect your switch from unwanted access:
V First define a new community which you can access from your computer
with all rights.
Note: Make a note of the community name and the associated index. For
security reasons, the community name cannot be read later. Access to the
community access, trap destination and trap configuration table is made via
the community index.
V Treat this community with discretion. Because everyone who knows the
community can access the switch MIB with the IP address of your
computer.
V Limit the access rights of the known communities or delete their entries.
