NETGEAR AV Line M4250 GSM4210PX 8-Port Gigabit PoE+ Compliant Managed AV Switch with SFP (220W) - Manual (Page 218)

If you select Disable, GMRP is not active and the join time, leave time, and leave all
time options are without any effect. The default is Disable.
10. In the Join Timer field, specify the time in centiseconds between the transmission
of GARP PDUs registering membership for a VLAN or multicast group.
Enter a number between 10 and 100 (0.1 to 1.0 seconds). The default is 20
centiseconds (0.2 seconds). An instance of this timer exists for each GARP participant
for each port.
11. In the Leave Timer field, specify the time in centiseconds to wait after receiving an
unregister request for a VLAN or multicast group before deleting the associated
entry.
This allows time for another station to assert registration for the same attribute to
maintain uninterrupted service. Enter a number between 20 and 600 (0.2 to 6.0
seconds). The default is 60 centiseconds (0.6 seconds). An instance of this timer
exists for each GARP participant for each port.
12. In the Leave All Timer field, specify how frequently (in centiseconds) LeaveAll PDUs
are generated.
A LeaveAll PDU indicates that all registrations will be deregistered soon. To maintain
registration, participants must rejoin. The leave all period timer is set to a random
value in the range of LeaveAllTime to 1.5 * LeaveAllTime. The timer is specified in
centiseconds. Enter a number between 200 and 6000 (2 to 60 seconds). The default
is 1000 centiseconds (10 seconds). An instance of this timer exists for each GARP
participant for each port.
13. Click the Apply button.
Your settings are saved.
It can take up to 10 seconds for GARP configuration changes to take effect.
14. To save the settings to the running configuration, click the Save icon.
Auto-VoIP
Voice over Internet Protocol (VoIP) enables telephone calls over a data network. Because
voice traffic is typically more time-sensitive than data traffic, Auto-VoIP provides
classification for voice packets so that they can be prioritized above data packets for
better quality of service (QoS). With Auto-VoIP, voice prioritization is based on call-control
protocols such as SIP, H.323, and SCCP on interfaces or organizationally unique Identifier
(OUI) bits.
