The UDP source and destination port matching feature allows the CTP to use a CESoPSN packet format which is compatible with third-party party vendor equipment.

The CESoPSN standard supports multiple packet formats. When this feature is disabled for CTP CESoPSN bundles, the supported CESoPSN packet format uses a fixed destination UDP port of 2142, and a user-selected source UDP port is in the range from 1 through 65535 (0x1 through 0xFFFF).

When this feature is enabled, the packet format changes so that both the source and destination UDP ports use the same user-selected value that is restricted to the range from 49152 through 65535 (0xC000 through 0xFFFF). If the existing configured bundle source UDP port (with this feature flag set) is not within the valid range, then both the source and destination UDP ports will automatically be modified to a default value of 49152 (0xC000). CESoPSN bundles between CTPs will not function properly unless this feature flag is set identically at both ends of the bundle.

To enable the configured source UDP port to be used for both the source and the destination for CESoPSN bundles:

From the Main Menu, select 1) Bundle Operations.
Select 3) CESoPSN.
Select a bundle from the list.
If you select an active bundle, you are prompted to disable the bundle before configuring it.
Select 2) Config.
Select 11) Advanced Options.
Configure option 14) UDP src / dst port matching as described in Table 1.

Table 1: CESoPSN Bundle UDP Source and Destination Port Matching in the CTP Menu
Field	Function	Your Action
UDP src / dst port matching	Enables you to use the configured source UDP port for both the source and the destination. The configured source UDP port number must be in the range from 49152 through 65535 while enabling this option. If not, the CTP system displays the following warning message and the source UDP port will be set to the default value 49152. Source UDP Port not in the range 49152-65535. Please re-configure Source UDP Port. Setting the Source UDP Port to default value 49152.	Select one: Yes No Default value is No.
