TX BW: 35 MHz RX BW: 35 MHz
5.3 IBR Frequency and Bandwidth:
TX: 5300 MHz RX: 5800 MHz
TX BW: 35 MHz RX BW: 35 MHz
TX BW: 35 MHz RX BW: 35 MHz
NOTES: These values might be changing as long as RRC is running.
The bandwidths do not need to match.
From the report, confirm that the two IBRs are compatible. In the example above, the link has one IBR that
transmits in the 5.8 GHz band receives in the 5.3 GHz band, and one IBR that transmits in the 5.3 GHz band
and receives in the 5.8 GHz band. Two identical radios will not communicate with one another.

Reset the Link
Reset the link with a soft reset. (If practical, do this on both ends of the link.)
a. Check the status of the link with the following CLI commands:
IBR101 # show interface radio 0 status
b. If the Status indicates the Transmitter is ON but the Status is DOWN, do the following:
IBR101 # configure terminal
IBR101 (config) # interfaces radio 0
IBR101 (config-rad-0) # rrc soft-reset
This will reset the link and radio, forcing a resync.
c. After 3 to 5 minutes check the radio status again.
IBR101 (config-rad-0) # exit
IBR101 (config) # exit
IBR101 # show interface radio 0 status
2.4.
Reboot the IBRs
a. If a Soft-Reset does not establish a link then save any configuration changes and reboot the IBRs.
IBR101 # copy running-config startup-config
IBR101 # reload
b. After 3 to 5 minutes check the radio status again.
IBR101 # show interface radio 0 status
2.5.
Check EIRP, RSL, & SNR
If the Status indicates the Link Status still is DOWN, check EIRP, RSL, and SNR. Values shown below are
samples only:
samples only:
EIRP: (should be > 15 dBm)
S0: 27.0 dBm S1: 27.0 dBm
Total: 30.0 dBm
RSL: (should be > - 84 dBm; remember that these are negative numbers)
1: - 68.5 dBm
2: - 69.0 dBm
3: - 68.0 dBm
4: - 68.5 dBm
SNR: (short-term SNR should be > 3 dB)
Short-term SNR: S0: 27 dB
S1: 27 dB
Long-term SNR: S0: 27 dB
S1: 27 dB
