Getting SPP Configurations

The scfg (Slice Configuration) command can be used to display the attributes of SPP interfaces. The two most common commands are: 

scfg --cmd get_ifaces           # display attributes of all interfaces
scfg --cmd get_peer --ifn N     # display IP address of interface N's peer

Examples of the displays are shown at the end of this page. Enter: 

scfg --help info

to see what other information command options there are.
