GVRP Timer Settings
The GVRP allows interoperability with other switches, so the values of the GVRP timers can be configured. This table
is used to set the GVRP Timer Settings.

The following fields can be set:
Parameter Description
Join Time
(100-100000)
The time in milliseconds that specifies the amount of time between the Switch receiving the
information about becoming a member of the group and actually joining the group. The default
is 200.
Leave Time
(100-100000)
The time in milliseconds that specifies the maximum amount of time between the Switch
receiving a leave group message from a host, and the Switch issuing a group membership
query. The default is 600. The Leave Time must be greater than 2 join times.
Leave All Time
(100-100000)
The time in milliseconds that specifies the amount of time the Switch will take to Leave All
groups. The default is 10000. The Leave All Time must be greater than the Leave Time.

Asymmetric VLAN Settings
Shared VLAN Learning is a primary example of the requirement for Asymmetric VLANs. Under normal circumstances,
a pair of devices communicating in a VLAN environment will both send and receive using the same VLAN; however,
there are some circumstances in which it is convenient to make use of two distinct VLANs, one used for A to transmit
to B and the other used for B to transmit to A in these cases Asymmetric VLANs are needed. An example of when this
type of configuration might be required, would be if the client was on a distinct IP subnet, or if there was some
confidentiality-related need to segregate traffic between the clients.
