Performing Radio Loopback (CLI)
You can perform loopback on a radio.
To set the timeout for a radio loopback, enter the following command:
radio[x/x]> radio loopbacks-timeout set duration <duration>
To display the radio loopback timeout, enter the following command:
radio[x/x]>radio loopbacks-timeout show
To activate an RF loopback, enter the following command:
radio[x/x]>rf loopback-rf set admin <admin>
Table 178 Radio Loopback CLI Parameters
Parameter Input Type Permitted Values Description
duration Number 0 – 1440 The timeout, in minutes, for automatic
termination of a loopback. A value of 0
indicates that there is no timeout.
admin Variable on
off Set on to initiate an RF loopback.
Examples
The following commands initiate an RF loopback on radio carrier 1 with a timeout of two minutes:
radio[2/1]> radio loopbacks-timeout set duration 2
radio[2/1]>rf loopback-rf set admin on
Performing Ethernet Loopback (CLI)
Ethernet loopbacks can be performed on any logical Ethernet interface except a LAG. When Ethernet loopback is
enabled on an interface, the system loops back all packets ingressing the interface. This enables loopbacks to be
performed over the link from other points in the network.
To configure loopback on an Ethernet interface, go to interface view for the interface and enter the following
command:
eth type eth[x/x]> loopback admin <loopback-admin-state>
