Vendor Classes
Since 6.45beta6 version RouterOS support vendor class id matcher. The vendor class is used by DHCP clients to optionally identify the vendor and configuration.
| Property | Description |
|---|---|
| name (string; Default: ) | Self explained |
| sever (string; Default: all) | Specific DHCP server to match |
| address-pool (string; Default: ) | Address pool for a particular Vendor ID (VID) |
| vid (string; Default: ) | Vendor Class ID matcher |
Example
In the following configuration example, we will give an IP address from a particular pool for an Android based mobile phone. We will use the RouterBOARD with a default configuration
/ip pool add name=default-dhcp ranges=192.168.88.10-192.168.88.254 add name=pool-for-VID ranges=172.16.16.10-172.16.16.120
Configure vendor-class-id matcher. DHCP servers configuration remains default
/ip dhcp-server add address-pool=default-dhcp disabled=no interface=bridge name=defconf /ip dhcp-server network add address=192.168.88.0/24 comment=defconf gateway=192.168.88.1 /ip dhcp-server vendor-class-id add address-pool=pool-for-VID name=samsung server=defconf vid=android-dhcp-9
Connect your mobile phone to the device to receive an IP address from 172.16.16.0 network
[admin@mikrotik] > /ip dhcp-server lease print detail

If you do not know your devices Vendor Class ID, you can turn on DHCP debug logs with /system logging add topics=dhcp. Then in the logging entries, you will see Class-ID

通过设置vcendor classes，让苹果手机获取到不同的IP段，然后不给这个IP段设置伪装上网。它就上不了网了！
