Selecting WAN Point to Point Connections
This step of the wizard allows you to select the interfaces on which to configure QoS for the Serial
Point-to-Point links in the WAN segment of your network. You should select all MLP and HDLC
interfaces (from both the central and the remote sites) that carry voice traffic.
For Point-to-Point links with speeds equal to or less than 768 kbs, you should select Multilink
interfaces—selecting a serial interface may cause a deployment failure.
The wizard will automatically configure QoS separately for groups of interfaces with link speeds greater
than 768kbs, and those with link speeds equal to or less than 768kbs.
In certain types of configurations where the rate of a multilink interface is not defined, and the serial
bandwidth is less than or equal to 768 kbits, the IP Telephony wizard assigns the multilink interfaces to
high speed policy groups instead of low speed policy groups.
To make the correct assignment in the IP Telephony wizard, you must define the bandwidth on the
multilink interface using the device’s bandwidth CLI command.
To select WAN Point to Point connections:
Step 1 Select the interfaces on which to configure QoS for the WAN Serial Point-to-Point links, by selecting
the check boxes next to the appropriate interfaces in the list.
For more information about the columns in this table, see IP Telephony Wizard: Select WAN Point to
Point Connections Page, page B-143.
Step 2 To remove any interfaces that were previously assigned for this voice role:
a. Click the Remove button in the Advanced section of the page.
A page appears, displaying the interfaces assigned for the WAN Point-to-Point voice role.
For more information about this page, see IP Telephony Wizard: Remove Network Elements Page,
page B-132.
b. Select the interfaces you want to unassign and click Remove.
The page closes.
Step 3 Click Next.
If the Display Configuration Info. check box is selected, the Configuration Info page appears. After
reviewing the assignments summary, click Next.
