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.
IP Addresses

Examples of Configuration Displays
What follows is the output of the get-info.sh script for the three GENI SPPs. The annotated output below shows which commands were used to produce the output.
