• GARP Join Timer – The interval between transmitting requests/queries
to participate in a VLAN group. (Range: 20-1000 centiseconds; Default:
20)
• GARP Leave Timer – The interval a port waits before leaving a VLAN
group. This time should be set to more than twice the join time. This
ensures that after a Leave or LeaveAll message has been issued, the
applicants can rejoin before the port actually leaves the group. (Range:
60-3000 centiseconds; Default: 60)
• GARP LeaveAll Timer – The interval between sending out a LeaveAll
query message for VLAN group participants and the port leaving the
group. This interval should be considerably larger than the Leave Time
to minimize the amount of traffic generated by nodes rejoining the
group.
(Range: 500-18000 centiseconds; Default: 1000)
Note: GARP timer settings must follow this rule: 2 x (join timer) < leave
timer < leaveAll timer
• Mode – Indicates VLAN membership mode for an interface.
(Default: Hybrid)
• 1Q Trunk – Specifies a port as an end-point for a VLAN trunk. A
trunk is a direct link between two switches, so the port transmits
tagged frames that identify the source VLAN. Note that frames
belonging to the port’s default VLAN (that is, associated with the
PVID) are also transmitted as tagged frames.
• Hybrid – Specifies a hybrid VLAN interface. The port may transmit
tagged or untagged frames.
• Dot1q-Tunnel – Configures IEEE 802.1Q tunneling (QinQ) to
segregate and preserve customer VLAN IDs for traffic crossing the
service provider network. See “Configuring IEEE 802.1Q
Tunneling” on page 296 for a detailed description of this feature.
• TPID (0-65535) – Tag Protocol Identifier specifies the ether-type of
incoming packets on a tunnel port. See “Configuring IEEE 802.1Q
Tunneling” on page 296 for a detailed description of this parameter.
• Address Monitor Mode – This feature must be enabled on a QinQ
tunnel port to properly forward traffic for the internal management
VLANs (VIDs 247-249) between the QinQ tunnel port and the SBC
connected to port 28. For a more detailed description, see “Configuring
IEEE 802.1Q Tunneling” on page 296.
