4. Set the holddown timer.

dialer timer enable interval

The default setting is 5 seconds.

5. Set the wait-carrier timer.

dialer timer wait-carrier wait-carrier

The default setting is 60 seconds.

6. Set the buffer queue length.

description text

The default setting is in the format of interface-name Interface, for example, Dialer1 Interface.

8. Set the keepalive interval.

timer-hold seconds

The default setting is 10 seconds.

9. Set the keepalive retry limit.

timer-hold retry retries

The default setting is five.

A link is removed after the keepalive retry limit is reached.

10. Set the MTU.

mtu size

The default setting is 1500 bytes.

11. Set the expected bandwidth.

bandwidth bandwidth-value

By default, the expected bandwidth (in kbps) is the interface baud rate divided by 1000.

12. (Optional.) Specify a primary traffic processing slot for the interface.

  • In standalone mode:service slot slot-number

  • In IRF mode:service chassis chassis-number slot slot-number

By default, no primary traffic processing slot is specified for an interface.
