DESCRIPTION

 

GVRP

Select the check box to permit VLANs groups beyond the local switch on

 

 

this port. GVRP (GARP VLAN Registration Protocol) is a registration

 

 

protocol that defines a way for switches to register necessary VLAN

 

 

members on ports across the network.

 

 

 

 

802.1q Port Isolation

Port Isolation allows each port to communicate with the CPU port, uplink

 

 

ports and stacking ports (if available) but not communicate with each

 

 

other. This option is the most limiting but also the most secure.

 

 

 

 

802.1q Ingress Check

Select this check box to set the switch to discard incoming frames for

 

 

VLANs that do not have this port as a member

 

 

 

 

VLAN Stacking

Select the check box to enable VLAN stacking.

 

 

In the SP TPID drop-down list box, select a standard Ethernet type code

 

 

to identify the frame and indicate whether the frame carries IEEE 802.1Q

 

 

tag information. Or select Others and then enter a four-digit hexadecimal

 

 

number from 0x0000 to 0xFFFF. 0x denotes a hexadecimal number. It

 

 

does not have to be typed in the Others field.

 

 

 

 

Bridge control protocol

Select the check box to allow the switch to handle bridging control

 

transparency

protocols (STP for example). You also need to define how to treat a

 

 

BPDU in the Port Setup screen.

 

 

 

 

Apply

Click Apply to save your changes back to the switch.

 

 

 

14.2 Priority Queue

Queuing is used to help solve performance degradation when there is network congestion.

Configure queuing algorithms for outgoing traffic in the Switch Setup screen. Queuing algorithms allow switches to maintain separate queues for packets from each individual source or flow and prevent a source from monopolizing the bandwidth.

Follow the steps below to configure priority queuing.

To open this screen, right-click on the switch in the Device List Panel, and click Configuration > Switch Configuration > Priority Queue to display the following screen.
