Hi Akber

From Cisco configuration guide

=============================================

This command specifies a message to be displayed when an EXEC process is created (a line is activated, or an incoming connection is made to a vty). Follow this command with one or more blank spaces and a delimiting character of your choice. Then enter one or more lines of text, terminating the message with the second occurrence of the delimiting character.

When a user connects to a router, the message-of-the-day (MOTD) banner appears first, followed by the login banner and prompts. After the user logs in to the router, the EXEC banner or incoming banner will be displayed, depending on the type of connection. For a reverse Telnet login, the incoming banner will be displayed. For all other connections, the router will display the EXEC banner.

To disable the EXEC banner on a particular line or lines, use the no exec-banner line configuration command

I copied and pasted you config in my router and I don't see that behavior. It's working as expected.

Press RETURN to get started.

User Access Verification

Username: test

Password:

you are into the exec mode. PLease enter your commands

One thing to keep in mind, if you are using SSH, you send the username and password information before getting the prompt. Try getting into the router via the console and see if the behavior is SSH or Banner related.
