Chapter8 Configuring VLANs
Assigning VLAN Port Membership Modes
VLAN Membership Combinations
You can configure your switch ports in the various VLAN membership combinations in Table 8-3.
Table 8-3 VLAN Combinations
Port Mode VTP Required? Configuration Procedure Comments
Static-access ports No “AssigningStatic-AccessPortsto
aVLAN” sectiononpage8-7
If you do not want to use VTP to globally
propagate the VLAN configuration
information, you can assign a static-access port
to a VLAN and set the VTP mode to
transparent to disable VTP.
The switch automatically transitions to VTP
transparent mode (VTP is disabled). No VTP
configuration is required.
Static-access and
trunk ports
Recommended “Configuring VTP Server Mode”
sectiononpage8-12
Adding, modifying, or removing
VLANs in the database as
described in the “Configuring
VLANs in the VTP Database”
sectiononpage8-17
“AssigningStatic-AccessPortsto
aVLAN” sectiononpage8-19
“Configuring a Trunk Port”
sectiononpage8-22
You can configure at least one trunk port on the
switch and make sure that this trunk port is
connected to the trunk port of a second switch.
Some restrictions apply to trunk ports. For more
information, see the “Trunks Interacting with
Other Features” section on page 8-21.
You can change the VTP version on the switch
and enable VTP pruning.
You can define the allowed-VLAN list, change
the pruning-eligible list, and configure the
native VLAN for untagged traffic on the trunk
port.
Dynamic-access and
trunk ports
Yes “Configuring Dynamic VLAN
Membership” section on
page 8-31
“Configuring Dynamic Ports on
VMPS Clients” section on
page 8-32
“Configuring a Trunk Port”
sectiononpage8-22so that the
VMPS client can receive VTP
information from the VMPS
Youmustconnect the dynamic-accessport to an
end station and not to another switch.
Configure the VMPS and the client with the
same VTP domain name.
You can change the reconfirmation interval and
the retry count on the VMPS client switch.
You can define the allowed-VLAN list, change
the pruning-eligible list, and configure the
native VLAN for untagged traffic on the trunk
port.
