switch. For example, if you are creating a VLAN called Sales with a
VID of 3 that spans three switches, assign the Sales VLAN on
each switch the VID value of 3.
VLAN Name— Specify the name of a VLAN. The name can be

from 1 to 20 characters in length. The first character must be a
letter; it cannot be a number. The name cannot contain spaces or
special characters, such as asterisks (*) or exclamation points (!).
You cannot assign the name of name of an existing VLAN on the
switch.
VLANs are easier to identify if their names reflect the functions of
their subnetworks or workgroups (for example, Sales or
Accounting). If a VLAN is unique in your network, then its name
must be unique as well. A VLAN that spans multiple switches must
have the same name on each switch.
Device ID— Assign a "T", "U", or "H" by clicking a port number until

the desired choice appears in the box below the port number. A "T"
indicates the port is a tagged port. A "U" indicates the port is an
untagged port. An "H" indicates the port does not belong to any
VLANs on the switch as an untagged port. To remove the port from
the VLAN, click the port number until the box is unchecked.
