In SLB, Port Translation Mode is similar to Translation Mode, except that in Port Translation Mode the physical Port where the node connects to must be configured as a Fast Ethernet Half Duplex port.
The majority of Extreme Networks switches have a dedicated out of band management port and VLAN. The 10/100BASE-TX Ethernet management port allows you to communicate directly to the CPU of the switch. If you want the switch to forward traffic from the mgmt VLAN to other VLANS you just have to enable ipforwarding on all VLANS including the management VLAN.
