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 AP,
presuming that the device supplies the correct Community String value.
The default treatment is to allow all networks access. For more information
on CIDR, execute an Internet search on “Classless Interdomain Routing.” You
are allowed to specify as many as 10 different accessing IP address, subnet
mask combinations.
RECOMMENDATION:
The subscriber can access the SM/BHS 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/BHS to filter (block) SNMP requests.
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) or DNS names to which
SNMP traps must be sent. Traps inform Wireless Manager or an NMS that
something has occurred. For example, trap information is sent
• after a reboot of the module.
• when an NMS attempts to access agent information but either
• supplied an inappropriate community string or SNMP version number.
•
is associated with a subnet to which access is disallowed.
Trap Enable, Sync
Status If the sync status traps (sync lost and sync regained) have to be sent to
Wireless Manager or an NMS, select Enabled. If these traps have to be
suppressed, select Disabled.
Trap Enable, Session
Status If you want session status traps sent to Wireless Manager or an NMS, select
Enabled.
LQI Traps This field enables and disables traps for LQI.
LQI threshold to raise
trap (delta from
reference LQI value) It is configured in percentage. The LQI trap is raised if the LQI values goes
below the configured threshold to raise trap from reference LQI. For
example, if the LQI threshold to raise trap is set as 30, the LQI trap will be
raised once the LQI goes below 70% (100-30).
LQI threshold to clear
trap (delta from
reference LQI value) It is configured in percentage. The LQI trap is cleared if the LQI values goes
above the configured threshold to clear trap from reference LQI. For
example, if the LQI threshold to clear trap is set as 25, the LQI trap will be
clear once the LQI goes above 75% (100-25).
