Edit Subnet Dialog Box
Lets you edit a subnet associated with a site.
The following table describes the fields in the dialog box.
Note: Subnets and Sites
You can assign a subnet to only one site.
Field Description
Name The name of the subnet. Required and must be unique.
IP address The IP address of the subnet.
Subnet mask length The CIDR (Classless Inter-Domain Routing) prefix size value (the number of
leading 1 bits in the routing prefix mask). This value, together with the IP
Address, defines the subnet.
For IPv4, a value of 24 is equivalent to specifying a dotted-quad subnet mask
of 255.255.255.0. A value of 16 is equivalent to specifying a dotted-quad
subnet mask of 255.255.0.0.
Max bandwidth (Mbps) The total bandwidth limit for voice and video calls. If not specified, the site limit
applies.
Max bit rate (kbps) The per-call bit rate limit for voice and video calls. If not specified, the site limit
applies.
Note: Bit rate is not the same as bandwidth. Since the bit rate applies in both
directions and there is overhead, the actual bandwidth consumed is about 2.5
times the bit rate selected.
When you specify both the bandwidth and bit rate limits, the dialog box shows
you how many calls at that bit rate the specified bandwidth supports.
Note: Subnets and Sites
You can assign a subnet to only one site.
Field Description
Name The name of the subnet. Required and must be unique.
IP address The IP address of the subnet.
