8.1 System Behavior
8.1.1 Base Station
1. Use of the secondary management channel (SMC) must be included in calculations
for the maximum aggregate uplink and downlink throughput rates.
2. A duplex mismatch between the base station or subscriber Ethernet port and the
connected Ethernet device may cause a lockup condition resulting in loss of data
connectivity over the Ethernet port. This issue can occur only if one device is set for
auto-negotiate and the other device has a manually set speed and duplex. Reset the
base station or subscriber to restore operation. For highest availability, configure
both Ethernet devices for the required speed and duplex.
3. The base station wireless downlink/uplink ratio combinations are dependant on the
current CP and Frame Duration settings.
4. Base station CLI commands will not function with subscriber names containing space
characters (blanks or white space). Use the Web GUI (or RedMAX RMS) to edit
subscriber names and remove any blank characters.
5. Continuous high-volume streams of CLI commands may cause the base station to
reset. It is recommended to insert one 'sleep 1' command for each 100 commands
issued to the base station and to use only one Telnet session when running CLI
scripts.
6. Continuous high-volume streams of SNMP commands may cause the base station to
reset. When using 3rd-party SNMP-based devices, insert a pause between SNMP
commands to allow sufficient processing time for the base station. It is strongly
recommended to configure only one RedMAX RMS system to monitor a base
station.
7. An event log (and syslog) message notification is sent whenever a pass-all classifier
is created for downlink service flows.
8. When using adjacent channels on collocated base stations, the Noise Level
indication on the Status screen may include signals from another base station.
9. When configuring UGS services on the base station, setting Max. Res BW or Min.
Res BW to zero (0) designates 'unlimited' bandwidth -- all subscriber bandwidth will
be allocated to this service flow (definition according to the 802.16.d standard).
10. The IP address field on the base station SS Info page is not populated until there is
activity on the secondary management channel (SMC) to that subscriber. The SMC
is not activate during subscriber registration, and some period of time may pass
before the SMC is activated (e.g., SNMP message from RMS). If required, an
operator can activate the SMC by opening a Telnet session to that subscriber via
one of the sector controller Ethernet ports.
11. When a base station software image is activated (switch software versions), the
current running configuration is overwritten with the configuration saved at the time
