ES3528-WDM Usage of Craft Port

-- This is outband management port. It is refer to port 29 in the CLI

-- It is use for separate the user traffic and management traffic.

-- Please follow the below steps to setup the craft port
1. Create a dedicated management VLAN
2. Configure the management IP address for the switch
3. Add only port 29 to the above VLAN
4. Connect RJ45 from the computer to the craft port
5. Set the same IP address range as switch's IP
6. Now it can either telnet or http to the switch's management


* It is only used for management. It should not carry user traffic. And please note that you can't pass traffic between port 29 and other front ports.
