# SCCP Network Configuration Mode Commands

The SCCP Network Configuration Mode is used to configure properties for Signaling Connection Control Part (SCCP) services for SS7.
In this mode, the command prompt should be similar to:

    [local]hostname(config-sccp-network-<sccp_id>)#

Signaling Connection Control Part (SCCP) is a routing protocol in the SS7 protocol suite in layer 4, which provides end-to-end routing for TCAP messages to their proper database.
