Deleting IP Routes

To delete an IP route, follow these steps:

Step 1 Type the deliproute command, specifying the destination address.

Step 2 Verify the route deletion using the lsiproutes command.

Synchronizing the System Clock

The MGX 8260 clock module has three synchronization options:

• BITS (Building Integrated Timing Source)—A high quality timing source that synchronizes all

equipment in the building

• Line—A clock derived from the receive line signal

• Local—An internal MGX 8260 timing source

You assign one clock source as the primary source and another as the secondary source. When using the

line clock source, specify both the line and slot associated with the source.

During normal operation, the primary clock is the active source and the secondary clock is the backup

source. If the active source fails, the MGX 8260 Media Gateway switches to the backup clock and

reports an alarm. You can also switch to the backup source manually. This section explains how to set

primary and secondary clocks and view clock status.

Setting Clock Parameters

To set the clock synchronization, specify the primary and secondary clocks using the chpclksrc and

chsclksrc commands, specifying the slot, line, source type and card type. Use the following table as a

guide:

The following example selects the BITS clock as the timing source:

chpclksrc 9 1 3 1

The line number doesn’t matter, but you need to specify it to execute the command.
