interface-by-interfacebasis. When you assign switch interfaces to VLANs by using this method, it is known
asinterface-based, or static,VLAN membership.
Trafficbetween VLANs must be routed or fallback bridged.
Theswitch can route traffic between VLANs by using switch virtual interfaces (SVIs). An SVI must be
explicitlyconfigured and assigned an IP address to route traffic between VLANs.
Supported VLANs
Theswitch supports VLANs in VTP client, server, and transparent modes. VLANs are identified by a number
from1 to 4094. VLAN IDs 1002 through 1005 are reserved for Token Ring and FDDI VLANs. VTP version
1and version 2 support only normal-range VLANs (VLAN IDs 1 to 1005). In these versions, the switch must
bein VTP transparent mode when you create VLAN IDs from 1006 to 4094. VTP version 3 supports the
entireVLAN range (VLANs 1 to 4094). Extended range VLANs (VLANs 1006 to 4094) are supported only
inVTP version 3. You cannot convert from VTP version 3 to VTP version 2 if extended VLANs are configured
inthe domain.
Theswitch or switchstack supports a totalof 1005 (normalrange and extended range) VLANs.However,
thenumber of routedports, SVIs, and otherconfigured features affects the use of the switch hardware.
Theswitch supports per-VLAN spanning-tree plus (PVST+) or rapid PVST+ with a maximum of 128
spanning-treeinstances. One spanning-tree instance is allowedper VLAN.
Theswitch supports IEEE 802.1Q trunking methods for sending VLAN traffic over Ethernet ports.
VLAN Port Membership Modes
Youconfigure a port to belong to a VLAN by assigning a membership mode that specifies the kind of traffic
theport carries and the number of VLANs to whichit can belong.
Whena port belongs to aVLAN, the switch learns and manages the addresses associated with the port on a
per-VLANbasis.

VTPis not required. If you do not
wantVTP toglobally propagate
information,set the VTP mode to
transparent.To participate in VTP,
theremust be at least one trunk port
onthe switchor the switchstack
connectedto a trunk port of a

Astatic-access port canbelong to
oneVLAN and is manually
assignedto that VLAN.
