AMI Configuration Commands
B.8.5.3 Showing J-2 Port Configuration
This command allows the user to display information about the configuration
of the ports on a J-2 network module. Enter the following parameters:
localhost::configuration port j2>
show
Port LineLength Loopback ClockSource
1D1 short none internal
1D2 short none internal
1D3 short none internal
1D4 short none internal
The fields in this display are defined as follows:
Port Indicates the port number of the network module.
LineLength Indicates the length of the physical cable that is
attached to this port. Can be
short
or
long
.
Loopback Indicates the loopback mode of this port. Can be one
of the following:
none , line , or diagnostic .
ClockSource For all network modules,
network
means that the
timing for this port is derived externally from the
incoming clock on this port.
Internal
means that the
timing is derived from either the on-board crystal
oscillator or is set to be derived from a specific port
number on a Series C network module that is defined
by the user. If set to a specific port number, the trans-
mit clock is derived from that port if available. If the
port source becomes unavailable, the on-board crys-
tal takes over as the transmit clock source.
