Canopy System User Guide Configuring an SM for the Destination
pmp-0229 (Mar 2013)
301
RECOMMENDATION:
The subscriber can access the SM by changing the subscriber device to the
accessing subnet. This hazard exists because the Community String and
Accessing Subnet are both visible parameters. To avoid this hazard, configure
the SM to filter (block) SNMP requests. See Filtering Protocols and Ports on
Page 435.
SNMP Trap Server DNS Usage
The management DNS domain name may be toggled such that the name of the trap server only
needs to be specified and the DNS domain name is automatically appended to that name. The
default SNMP trap server addresses for all 10 available servers is 0.0.0.0 with the appending of the
DNS domain name disabled.
Trap Address 1 to 10
Specify ten or fewer IP addresses (xxx.xxx.xxx.xxx) to which trap information should be sent.
Trap information informs Prizm or an NMS that something has occurred. For example, trap
information is sent
• after a reboot of the module.
• when Prizm or an NMS attempts to access agent information but either
o supplied an inappropriate community string or SNMP version number.
o is associated with a subnet to which access is disallowed.
Site Information Viewable to Guest Users
Operators can enable or disable site information from appearing when a user is in GUEST account
mode.
Site Name
Specify a string to associate with the physical module. This parameter is written into the sysName
SNMP MIB-II object and can be polled by Prizm or an NMS. The buffer size for this field is 128
characters.
Site Contact
Enter contact information for the module administrator. This parameter is written into the
sysContact SNMP MIB-II object and can be polled by Prizm or an NMS. The buffer size for this
field is 128 characters.
