iii In the Link ID field, enter a unique link identifier from 1 to 65535. The Link ID identifies the link, in
order to distinguish it from other links. If the Link ID is not the same at both sides of the link, a Link ID
Mismatch alarm is raised. If Link ID Mismatch Security is enabled, traffic is also blocked on the link. See
Enabling Link ID Mismatch Security.
iv In the RSL degradation alarm admin field, select Enable if you want the unit to generate an alarm in
the event that the RSL falls beneath the threshold defined in the RSL degradation threshold field. The
range of values is -99 to 0. By default, the alarm is disabled, with a default degradation threshold of 68
dBm. The RSL degradation alarm is alarm ID 1610, Radio Receive Signal Level is below the configured
threshold.
The alarm is cleared when the RSL goes above the configured threshold. The alarm is masked if the
radio interface is disabled, the radio does not exist, or a communication-failure alarm (Alarm ID #1703)
is raised.

Enabling Link ID Mismatch Security
You can configure the unit to block all Ethernet and TDM traffic over the radio link in the event of a Link ID
mismatch by enabling Link ID Mismatch Security. When Link ID Mismatch Security is enabled and a Link ID
mismatch occurs:
•
All Ethernet and TDM traffic over the link is blocked.
•
The operational status of the radio is set to Down.
•
Automatic State Propagation is triggered.
•
You cannot change the Link ID of the remote radio, but the local-remote channel remains open for other
remote configurations.
•
In-band management is lost. Once the mismatch is cleared, in-band management is automatically restored.
•
The relevant interfaces are treated as being Down for purposes of MSTP and G.8032.
Link ID Mismatch Security must be enabled and disabled via CLI.
To enable Link ID Mismatch Security, enter the following command in root view:
root> platform security link-id mismatch security set admin enable
To disable Link ID Mismatch Security, enter the following command in root view:
root> platform security link-id mismatch security set admin disable
To display the current Link ID Mismatch Security setting, enter the following command in root view:
root> platform security link-id mismatch security show admin
By default, Link ID Mismatch Security is disabled.
