Applies to:
Microsoft Teams

As an Admin, you can use the Windows PowerShell command, New-CsTenantNetworkSubnet to define network subnets and assign them to network sites. Each internal subnet may only be associated with one site. Tenant network subnet is used for Location Based Routing.

Syntax

New-CsTenantNetworkSubnet
   [-Identity] <string>
   -MaskBits <int>
   [-Description <string>]
   [-NetworkSiteID <string>]
   [-WhatIf]
   [-Confirm]
   [<CommonParameters>]
New-CsTenantNetworkSubnet
   -MaskBits <int>
   -SubnetID <string>
   [-Description <string>]
   [-NetworkSiteID <string>]
   [-WhatIf]
   [-Confirm]
   [<CommonParameters>]

Description

IP subnets at the location where Teams endpoints can connect to the network must be defined and associated to a defined network in order to enforce toll bypass. Multiple subnets may be associated with the same network site, but multiple sites may not be associated with a same subnet. This association of subnets enables Location-Based routing to locate the endpoints geographically to determine if a given PSTN call should be allowed. Both IPv4 and IPv6 subnets are supported. When determining if a Teams endpoint is located at a site an IPv6 address will be checked for a match first.

When the client is sending the network subnet, please make sure we have already whitelisted the IP address by running this command-let, otherwise the request will be rejected. If you are only adding the IPv4 address by running this command-let, but your client are only sending and IPv6 address, it will be rejected.

Examples

Example 1

PS C:\> New-CsTenantNetworkSubnet -SubnetID "192.168.0.1" -MaskBits "24" -NetworkSiteID "site1"

The command shown in Example 1 created the network subnet '192.168.0.1' with no description. The subnet is IPv4 format, and the subnet is assigned to network site 'site1'. The maskbits is set to 24.

IPv4 format subnet accepts maskbits from 0 to 32 inclusive.

Example 2

PS C:\> New-CsTenantNetworkSubnet -SubnetID "2001:4898:e8:25:844e:926f:85ad:dd8e" -MaskBits "120" -NetworkSiteID "site1"

The command shown in Example 2 created the network subnet '2001:4898:e8:25:844e:926f:85ad:dd8e' with no description. The subnet is IPv6 format, and the subnet is assigned to network site 'site1'. The maskbits is set to 120.

IPv6 format subnet accepts maskbits from 0 to 128 inclusive.
