Securing a channel

We can secure a channel using MQSC commands or using the operations and control panels.

To secure a channel using the MQSC commands, use SET CHLAUTH.

Use the operations and control panels, starting from the initial panel, complete these fields and press enter:

Field	Value
Action	8

You are presented with an editor within which we can provide an MQSC command, in this case a CHLAUTH command, see Figure 1. When we have finished typing in the command, the plus signs (+) are needed. Type PF3 to exit from the editor and submit the command to the command server.
