To configure a serial raw socket on a 7705 SAR

Before you begin

A raw socket IP transport interface can be configured for each RS-232 serial port on an NE. IP transport interfaces are only supported on RS-232 serial ports with the Encap Type parameter configured as RAW. This allows the serial port to receive TCP connections or UDP session packets from multiple remote-hosts when operating as a server, or to create new multiple sessions to remote-hosts in order to send and receive serial data when operating as a client.

Configuration of serial raw sockets is supported on the 7705 SAR-8, 7705 SAR-18, 7705 SAR-H, and 7705 SAR-Hc, Release 8.0 R4 or later.

There are two main configurations required for a serial raw socket to be operational and support sending/receiving serial data in either server mode, client mode, or both:

  1. Port level socket configuration - This includes serial link parameters such as baud rate, start/stop, bits, etc. Socket level configurations are required such as end-of-packet checking parameters and the inter-sessions delay for transmitting sessions data out of the serial link.

  2. IP transport services configuration – Creating an IP transport service is required to associate the serial port within either an IES or VPRN so that TCP/UDP encapsulated serial data can be routed within the corresponding Layer 3 service. This configuration includes IP transport local-host items (local servers) and remote host configurations, TCP timers and sessions control, etc. See To configure IP transport on an IES site and To configure IP transport on a VPRN site for more information.

Steps
 
1 

Configure the applicable MDA for the 7705 SAR NE. See To configure an MDA for more information.

The 7705 SAR-8 and 7705 SAR-18 must be configured with a 12-port Serial Data v2 or v3 MDA.

The 7705 SAR-H must be configure with a 2 × Serial Data + 2 × Channelized DS1/E1 MDA.

The 7705 SAR-Hc has fixed MDAs that cannot be modified.

2 

In the navigation tree Equipment view, right-click on the port and choose Create Channel/Socket. The Serial Channel (Create) form opens.

3 

Click on the States tab and configure the Administrative State parameter as Up.

4 

Click Apply and confirm your action.

5 

Click on the General tab and enable the Serial Socket Enabled parameter.

Note: When you enable the Serial Socket Enabled parameter, the Channel tab is no longer available and the RS-232/Socket tab appears. The NFM-P will automatically set the Device Mode parameter as Asynchronous and the Gender parameter as DCE, on the RS-232/Socket tab.

6 

Select a Socket Profile ID in the Socket Profile panel and click Apply.

7 

Click on the RS-232/Socket tab and configure the required parameters.

8 

Save your changes and close the form.

You can click on the IP Transports tab to view the IP Transport to which this serial raw socket is associated.
