Network Configuration Specifics
257
The commands required to change the network port settings are:
Switch(config)#
interface fastethernet0/1
Switch(config-if)#
switchport mode access
Switch(config-if)#
switchport access vlan 100
Switch(config-if)#
mls qos trust cos
Switch(config-if)#
mls qos cos 0
Switch(config-if)#
wrr-queue cos-map 4 5
Switch(config-if)#
priority-queue out
Switch(config-if)#
switchport voice vlan 2
Switch(config-if)#
spanning-tree portfast
Switch(config-if)#
end
Switch#
The above set of commands carries out the following, in order:
1. The port is configured as a static access port.
2. Untagged data is sent to VLAN 100.
3. The port will trust the priority information presented in any VLAN tagged frames and pass
through any Diffserv settings unmodified.
4. The default priority for COS is 0, which will be assigned to untagged traffic.
5. The Expedite Forwarding queue (Q4) is enabled with a COS value of 5.
6. The Voice VLAN, or Auxiliary_VLAN, is set for VLAN 2.
7. Spanning Tree Messages are allowed through but will not disconnect the port during the
learning phases of this protocol.
On some network switches the Voice VLAN is identified through the Auxiliary_VLAN command
set port auxiliaryvlan 0/1 2 . This sets port 0/1 to VLANID 2 for voice traffic.
VLAN MEMBERSHIP POLICY SERVER (VMPS)
VLAN Membership Policy Server (VMPS) provides two main features when installed and
operational. These are
• Security Checking
• Automatic assignment of VLAN for untagged traffic.
Since a network port can have only a single untagged to tagged VLAN mapping, VMPS is
typically used to identify a single attached device to the appropriate VLAN. Multiple devices
with different VLAN requirements will cause the switch port to shuttle between settings, with
resulting poor operation. A phone and PC would normally be such a combination. IP phone
messaging compatibility with CDP overcomes this limitation. Thus, an IP phone that is
