2.6.12 SKA command mode
SKA refers to Secure Customer Connections. In this menu, it provides DHCP snooping,
DHCP option 82, DHCP layer 2 relay and customer port (Port number 1~22) filtering
functions.
DHCP Option 82 Guidelines
The Managed Switch can add information about the source of client DHCP requests that
relay to DHCP server by adding Relay Agent Information. This helps provide authentication
about the source of the requests. The DHCP server can then provide an IP address based
on this information. The feature of DHCP Relay Agent Information adds Agent Information
field to the Option 82 field that is in the DHCP headers of client DHCP request frames.
Guidelines:
 Enable DHCP Option 82 Relay Agent global setting.
 Create Option 82 and trust port setting.
 Create Static IP table for authorized IP address.
 Each port‟s (Port Number 1~22) configuration for DHCP, Static IP or Unlimited.
