refuse to make a connection with any other communication unit. The units are locked using the uniqueauthorization keys. The keys are exchanged between the units concerned. The authorization keys canbe backed up to an external medium to be able to make a service unit exchange, if necessary. ShouldThe Link authorization quard be disabled, the user data occurs even it the remote unit is not authorized.The Secured mode set up process consists of a few steps:• Unique authorization keys generation:cli_link_key_gen -t b• Authorization keys exchange between the two communication units:cli_link_key_swap• Authorization keys activation:cli_link_key_apply -t bParameter -t determines whether we configure the whole link (-t b) or only one unit (-t l).• Secured mode activation. Both sides of the link must have identically secured mode set On or Off:cli_cnf_set -t b SVC_SECURE_PEER_MODE=on PEER_SVC_SECURE_PEER_MODE=on• Secured mode de-activation:cli_cnf_set -t b SVC_SECURE_PEER_MODE=off PEER_SVC_SECURE_PEER_MODE=off• Backup of the keys to an external medium. The backup has to be performed to be able to makeservice exchange of the corrupted unit, if necessary. The new exchanged unit is not able to makean active connection with the other unit if it is not loaded with the proper authorization key.cli_link_key_save -s s -f The key is backed up to a selected file in the internal unit file system. It can be transferred to an ex-ternal medium using for example the scp client.• Authorization key restoration from the external medium.The key has to be transferred to the unit internal file system first. The scp client can be used. TheCLI commands can be applied subsequently:cli_link_key_load -t b -f cli_link_key_apply -t b6.3.4. Radio loopback"Radio loopback" function (accessible via CLI only) provides indicative measurement of XPD (crosspolar discrimination). XPD is the ratio between desired signals on preferred polarization and signalson opposite polarization.• Commandcli_rloopThe Radio loopback command takes 10 seconds. The result is suppression [dB] of the unwanted signal(transmitter to receiver penetration). Radio loopback can only be used with units operating in 17 GHzor 24 GHz band.WARNING: User traffic is interrupted during command execution!139© RACOM s.r.o. – RAy3 Microwave LinkCommand Line Interface
