6.1 Password for SNMP access
6.1.1 Description Password for SNMP access
A network management station communicates with the Switch via the Simple
Network Management Protocol.
Every SNMP packet contains the IP address of the sending computer and the
password 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 password with the entries in the MIB of the Switch
(see
“Management Information BASE MIB” on page 220). If the password
has the appropriate access right, and if the IP address of the sending com-
puter has been entered, then the Switch will allow access.
In the delivery state, the Switch is accessible via the “public” password (read
only) and the “private” one (read and write) from every computer.
To protect your Switch from unwanted access:
V First define a new password which you can access from your computer
with all rights.
V Treat this community with discretion. Because everyone who knows the
password can access the Switch MIB with the IP address of your
computer.
V Limit the access rights of the known passwords or delete their entries.
