6. Use Leave All Time (centiseconds) to control how frequently LeaveAll PDUs are
generated. A LeaveAll PDU indicates that all registrations will shortly be deregistered.
Participants will need to rejoin in order to maintain registration. 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
factory default is 1000 centiseconds (10 seconds). An instance of this timer exists for each
GARP participant for each port.

Auto-VoIP Configuration
The Auto-VoIP automatically makes sure that time-sensitive voice traffic is given priority over
data traffic on ports that have this feature enabled. Protocol-based Auto-VoIP checks for
packets carrying the following VoIP protocols:
• Session Initiation Protocol (SIP)
• H.323
• Signalling Connection Control Part (SCCP)
• Media Gateway Control Protocol (MGCP)
VoIP frames that are received on ports that have the Auto-VoIP feature enabled are marked
with the configured CoS Traffic Class.
OUI-based Auto VoIP scans traffic for Organizationally Unique Identifier (OUI) bits. Traffic
with known OUI-bits can be placed in a specific VLAN and assigned an 802.1p priority value.
From the Auto-VoIP link, you can access the following pages:
• Protocol-Based on page 134
• OUI-Based on page 136
