NOTE:
You can unset either password (revert the access to no password required). To
do so, type a space into the field and reboot the module. You must enter any
password twice to allow the system to verify that the password is not mistyped.
After any password is set and a reboot of the module has occurred, a Password
Set indicator appears to the right of the field.
RECOMMENDATION:
Note the passwords that you enter. Ensure that you can readily associate these
passwords both with the module and with the other data that you store about the
module.
Webpage Auto Update
Enter the frequency (in seconds) for the web browser to automatically refresh the web-
based interface. The default setting is 0. The 0 setting causes the web-based interface to
never be automatically refreshed.
If you change this value and then click Save Changes, then the change becomes
effective immediately and the previous value is lost.
SNMP Community String
Specify a control string that allows an Network Management Station (NMS) to access
SNMP information. No spaces are allowed in this string. The default string is Cyclone.
The SNMP Community String value is clear text and is readable by a packet monitor.
Additional security derives from the configuration of the SNMP Accessing Subnet,
Trap Address, and Permission parameters.
SNMP Accessing Subnet
Specify the addresses that are allowed to send SNMP requests to this CMMmicro. The
NMS has an address that is among these addresses (this subnet). You must enter both
• The network IP address in the form xxx.xxx.xxx.xxx
• The CIDR (Classless Interdomain Routing) prefix length in the form /xx
For example
• the /16 in 198.32.0.0/16 specifies a subnet mask of 255.255.0.0 (the first 16 bits
in the address range are identical among all members of the subnet).
• 192.168.102.0 specifies that any device whose IP address is in the range
192.168.102.0 to 192.168.102.254 can send SNMP requests to the CMMmicro,
presuming that the device supplies the correct SNMP Community String value.
