■ Because GVRP is not compatible with the BPDU tunneling feature, you must
disable BPDU tunneling before enabling GVRP on a BPDU tunneling-enabled
Ethernet interface.
■ Because global GVRP is not compatible with Isolate-user-VLAN, make sure that
no Isolate-user-vlan has been created on the switch before enabling GVRP.
■ You should enable GVRP globally before enabling it on a port.
■ The port on which you want to enable GVRP must be a trunk port.
Configuring GARP
Timers
Follow these steps to configure GARP timers:
When configuring GARP timers, note that their values are dependent on each
other and must be a multiplier of five centiseconds. If the value range for a timer is
not desired, you may change it by tuning the value of another related timer as
shown in the following table:
