Example
The following procedure shows you how to configure the OpFlags and VLANSetting parameters to allow
the Cisco ATA to use a user-specified VLAN ID. In this example, the voice VLAN ID is 115 (in decimal
format).
Set bits 4-6 of the OpFlags parameter to 1, 0, and 1, respectively. This setting translates to the following
Step 1
bitmap:
xxxx xxxx xxxx xxxx xxxx xxxx x101 xxxx
The remaining bits of the OpFlags parameter, using all default values, make up the following bitmap
representation:
0000 0000 0000 0000 0000 0000 0xxx 0010
Therefore, the resulting value of the OpFlags parameter becomes the following bitmap representation:
0000 0000 0000 0000 0000 0000 0101 0010
