Ethernet Carrier Drop Settings
The Ethernet Carrrier Drop settings are used to control
failover switching between the primary and backup link in
response to capacity loss due to rain.
Carrier Drop Operation This setting is used to control
the Ethernet Carrier Drop feature. Settings are: Disabled ,
Enabled , and Use Pulse . The default is Disabled .
Use Pulse and Enabled are the two different methods used
to signal to the failover mechanism that it should switch to
the backup link:
•
Use Pulse The LAN link is toggled off.
• Enabled The LAN link will be turned off and left off.
Pulse Duration (Available if Carrier Drop Operation is set
to Use Pulse .) This is the length of time that the LAN link
remains down to trigger failover. The default is 5 seconds.
Block Data After Pulse (Available if Carrier Drop
Operation is set to Use Pulse .) Enable this option to stop
data from passing through the link when it is experiencing
loss of capacity. The default is
Off .
Enable Ethernet If No Session Enable this option to
allow management data (such as GUI, SNMP, and ping
packets) to pass, even if the Block Data After Pulse option is
enabled. The default is Off .
Wait for First Session Enable this option to cause the
system to wait until the Ethernet link has been successfully
established following a power cycle, to keep the link
from being dropped due to the throughput being below
threshold. The default is
Off .
First Session Validation Timer Use this setting to specify
how long to wait before triggering a link failure due to
insufficient threshold capacity following a power cycle.
The default is
0 seconds.
TX Capacity Low Threshold This is the minimum
allowable TX capacity; if the TX capacity goes below this
threshold, the Ethernet link will be dropped. The default is
0 Mbps.
TX Capacity High Threshold This is the TX capacity
required before a dropped link can be declared to be
operational again. The Ethernet link will remain down
until the TX capacity reaches this threshold. The default
is
0 Mbps. This setting should be greater than the TX
Capacity Low Threshold to avoid flutter and multiple OSPF
convergences.
RX Capacity Low Threshold This is the minimum
allowable RX capacity; if the RX capacity goes below this
threshold, the Ethernet link will be dropped. The default is
0 Mbps.
RX Capacity High Threshold This is the RX capacity
required before a dropped link can be declared to be
operational again. The Ethernet link will remain down
until the RX capacity reaches this threshold. The default
is
0 Mbps. This setting should be greater than the RX
Capacity Low Threshold to avoid flutter and multiple OSPF
convergences.
Low Threshold Timer This is the number of continuous
seconds that the radio must remain under the minimum
TX or RX capacity threshold before the link is dropped. If
set to 0, then as soon as capacity drops below a set limit,
the Ethernet link will be dropped. Default is
0 seconds.
High Threshold Timer
This is the number of continuous
seconds that the radio must remain above the maximum
TX or RX capacity threshold before the link is declared
operational again. The default is
0 seconds.
