Configuring Explicit Paths on CES VCs
To send a DeleteConnection request for a connection that exists, the ATM switch router specifies
the destination address of the UDP packet as the source UDP address in the CreateConnection
request.
To alter this behavior, and send responses and requests to a specific IP address and UDP port, use the
following global configuration command:
Note If the IP address is specified without the UDP port number, the well-known SGCP port2427 is used.
Example
The following example shows how to set the call-agent with IP address 133.20.5.122 and
UDP port 12000:
Switch(config)# sgcp call-agent 133.20.5.122 12000

Shutting Down SGCP

When SGCP is disabled with the no sgcp command, active SGCP connections are terminated; however
DeleteConnection requests are not sent to the call-agent for these active connections. To notify call-agent
and perform a graceful SGCP shutdown, use the following global configuration c ommand:
Example
The following example shows how to perform a graceful shutdown:
Switch(config)# sgcp graceful-shutdown
Configuring Explicit Paths on CES VCs
The explicit path feature enables you to manually configure either a fully specified or partially specified
path for routing CES soft permanent virtual channels (soft PVC) and SVC connections. Once these
routes are configured, up to three explicit paths might be applied to these CES connections.
A fully specified path includes all adjacent nodes for all segments of the path. A partially specified path
consists of one or more segment target nodes that should appear in their proper order in the explicit path.
The standard routing algorithm determines all unspecified parts of the partially specified path.
You can specify a path name for an explicit path and the switch assigns the next available unused path-id
value, or you can choose the path-id value and assign or modify its name.
For overview information about explicit paths, refer to the Guide to ATM Technology. For additional
explicit path configuration information, see the “Configuring Explicit Paths” section on page 11-36.
Command Purpose
sgcp call-agent ip-address udp-port Configures the call-agent IP address and UDP
port.
Command Purpose
sgcp graceful-shutdown Shuts down SGCP and notifies call-agent.
