how each is configured.
Abbreviations
The following abbreviations are used throughout this chapter.
GARP: General Attribute Registration Protocol
GVRP GARP VLAN Registration Protocol
MGMT: Management.
PVID: A tagged port’s VLAN ID. Range is 1…4094.
STP: Spanning tree protocol.
Tagged Frame: Frame with 802.1Q VLAN Tag header.
Untagged Frame: Frame either without 802.1Q VLAN Tag header, or with
this header and with VID = 0.
VID: VLAN ID in the range of 1…4095.
◆ Note: The terms “groups” and “segments” are both used to
represent VLAN segments in the system. They are num-
bered from 1 to 64. VLAN Groups
The IntraChassis 9000 supports 64 manually configurable VLAN Groups. A
VLAN group is uniquely identified by a 12-bit (1-4095) VLAN ID (VID). No
two VLAN Groups can have the same VID if they reside on the same switch.
Each VLAN group has a portmap that specifies the port members of the VLAN
and a set of untagged ports, which specifies the port members of the VLAN
group that transmit only VLAN untagged frames. The untagged set can be a
subset of the portmap, or it can be the same as the portmap, but it cannot have
ports that are not part of the portmap. If a port is in the VLAN portmap and
not in the VLAN untagged set, then the port transmits tagged frames only. A
VLAN group can be shared with other VLAN groups for MAC address learning
purposes.
