6.6 Establishing A Link
Except in the most severe cases of in-band interference, a pair of IBR’s will automatically
select the best combination of channel frequencies and bandwidth for a link.
(a) Wait for radios to finish booting and establishing a link.
(b) Use the CLI command shown below to verify that a link has been established.
IBR58 (config) # show interfaces radio 0 status
If a link is not automatically established within ten minutes , then consider the following
troubleshooting suggestions:
o Check to ensure that the other IBR on the link is operational.
o Change the direction in which the IBR is pointed.
o Change the IBR’s elevation.
o Determine if the link is too long for the environment.
6.7 IAS - Link Interference Analysis
IAS is a tool that IBR uses to analyze interference levels in receive channels and to select a
combination of channels and bandwidths that maximize throughput while minimizing the
effects of interference. The operator can display IAS data by executing the following
command.
IBR58 # show interface radio 0 ias
This command will return a table of data that shows the interference level in each receive
channel as received by each internal IBR antenna. The table below shows a partial output for
a 5.8 GHz radio (receives at 5.3 GHz).

7. Features & Functionality
7.1 Communication Protocols
IBR can be managed by an operator using:
o CLI: SSH, Telnet, Serial Console
o SNMP
7.2 Software Management
o Software upgrades to IBR can be made by an operator.
o Boot loader recovery can be accomplished by an operator via CLI.
o IBR has the ability to recover on its own from a failed software upgrade.
7.3 SNMP
