8. In the Join Timer field, specify the time in centiseconds between the transmission of GARP
PDUs registering (or reregistering) 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.
9. 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.
10. 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.
11. Click the Apply button.
The updated configuration is sent to the switch. Configuration changes take effect
immediately.
Configure 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, the Auto-VoIP feature helps
provide a classification mechanism for voice packets so that they can be prioritized above
data packets in order to provide better Quality of Service (QoS). With the Auto-VoIP feature,
voice prioritization is provided based on call-control protocols (SIP, SCCP, H.323) or OUI bits.
Configure Protocol-Based Port Settings
To prioritize time-sensitive voice traffic over data traffic, protocol-based Auto-VoIP checks for
packets carrying the following VoIP protocols:
• Session Initiation Protocol (SIP)
• H.323
• Signalling Connection Control Part (SCCP)
VoIP frames that are received on ports that for which the Auto-VoIP feature is enabled are
marked with the specified CoS traffic class value.
