DES-3326S Layer 3 Fast Ethernet Switch User’s Guide

Forbidden	Forbidden Non-Member - specifies
	the	port as not being a member of
	the	VLAN and that the port is
	forbidden from becoming a member
	of the VLAN dynamically.

IP Forwarding

Entries into the switch’s forwarding table can be made using both MAC addresses and IP addresses. Static IP forwarding is accomplished by the entry of an IP address into the switch’s Static IP Routing table.

To enter an IP address into the switch’s IP Forwarding Table, click the Forwarding Folder and then the IP Forwarding folder, and the click the Static/Default Routes link:
