Configuring Switching Information 323
Each VLAN in a network has an associated VLAN ID, which appears in the IEEE 802.1Q tag in the Layer
2 header of packets transmitted on a VLAN. An end station may omit the tag, or the VLAN portion of
the tag, in which case the first switch port to receive the packet may either reject it or insert a tag using
its default VLAN ID. A given port may handle traffic for more than one VLAN, but it can only support
one default VLAN ID.

VLAN Membership
Use the VLAN Membership
page to define VLAN groups stored in the VLAN membership table. Your
switch supports up to 4094 VLANs. However, you can actually create only 4092 VLANs because:
• VLAN 1 is the default VLAN of which all ports are members, and
• VLAN 4095 is designated as the "Discard VLAN."
Valid VLANs that can be created are 2–4093. VLAN 4094 is reserved.

page, click Switching > VLAN > VLAN Membership in the tree
