AN-30 System User Manual
- w (Write):
use ‘Write’ to grant write access permission to members of this
community
- t (Trap):
use “Trap” to grant read access permission to members of the trap
community
snmptrap (Trap Enable /Disable and Destination):
To add a trap destination for an
SNMP community type:
snmptrap add
<community name> <IP destination>
Or to delete a trap destination for an SNMP community:
snmptrap del
<community name> <IP destination>
When the SNMP Agent in the AN-30 detects an error condition, a message known as a
trap is sent. A Trap Host is an IP workstation/server that is set up to receive SNMP trap
messages.
rfchannel (RF Channel):
specifies the operating channel of the system, within the 100
MHz available in the 5.8 GHz band. The table below specifies the center frequencies of
each permitted channel.
Table 3: RF Channel Center Frequencies
Channel
Frequency
1 5735
MHz
1A 5745
MHz
2 5755
MHz
2A 5765
MHz
3 5775
MHz
3A 5785
MHz
4 5795
MHz
4A 5805
MHz
5 5815
MHz
To avoid interference, two PTP links operating in the same physical location (co-located)
or within close proximity must be separated by at least one channel, i.e., the gap between
channels must be 20 MHz or more (e.g., channels 2 and 3). Refer to Section 10.4 for
further information regarding deployment conventions.
txpower (Max Tx Power):
this parameter specifies the maximum power level of the
system. Depending on the RF channel and FCC regulations, the software will determine
the actual power to be used, which will not exceed this user defined value. Refer to Table
4 below. The Actual Tx Power is displayed on the System Status page.
The Actual Tx Power is set by the software / firmware to the maximum power permitted
for each channel according to the modulation scheme, as shown in the following table.
