Description

GARP *1

 

Group Address Registration Protocol is used by GVRP and GMRP to

 

 

register or deregister client attributes for client services within a bridged

 

 

LAN.

Join Time

20

The interval (centiseconds) between transmitting requests/queries to

 

 

participate in a group.

Leave Time

60

The interval (centiseconds) a port waits before leaving a group. This

 

 

time should be set to more than twice the Join Time. This ensures that

 

 

after a Leave or LeaveAll message has been issued, the applicants

 

 

can re-join before the port actually leaves the group.

Leave All Time

1000

The interval (centiseconds) between sending out a LeaveAll query

 

 

message for group participants and the port leaving the group. This

 

 

interval should be considerably larger than the Leave Time to minimize

 

 

the amount of traffic generated by nodes rejoining the group.

 

 

 

1:The default values for the GARP timers are independent of the media access method or data rate. These values should not changed unless you are experiencing some difficulties with GMRP or GVRP registration/deregistration.

Rx All,

Tx Untag

The VLAN ID assigned to untagged frames received on this port.

Set the default ingress priority to any value beneath the priority threshold to specify the low priority queue, or to any value equal to or above this threshold to specify the high priority queue.

Indicates whether or not VLAN tags will be included on frames passing through this port. The options include:

Rx All:

Accepts all frames, tagged or untagged.

Rx Untag: Only accepts untagged frames.

Tx All:

If PVID and frame tag are same, sends tagged frame,

otherwise sends untagged.

Tx Untag: Sends only untagged frames.

2:The switch supports Quality of Service (QoS) by using two or four priority queues, with Weighted Fair Queuing for each port. Inbound frames that do not have VLAN tags are tagged with the input port’ s default ingress user priority, and then placed in the appropriate priority queue at the output port. The default priority for all ingress ports is zero. Therefore, any inbound frames that do not have priority tags will be placed in the low priority queue of the output port. (Note that if the output port is an untagged
