如何在Cisco交换机上配置语音VLAN

在Cisco交换机上配置两个VLAN(Virtual Local Area Networks),一个用于语音，一个用于数据。
使用Cisco IOS命令来配置交换机
配置两个VLAN，一个用于语音，一个用于数据，并在Cisco Unified CME路由器(Cisco 3825 router)和交换机(Cisco catalyst 3560)之间建立一个trunk，在Cisco Catalyst Switch的一个外部接口上配置Cisco IOS Quality-of-Service(QoS)


主要步骤：
1. enable
2. vlan database
3. vlan vlan-number name vlan-name
4. vlan vlan-number name vlan-name
5. exit
6. wr
7. configure terminal
8. macro global apply cisco-global
9. interface slot-number/port-number
10. macro apply cisco-phone $AVID number $VVID number
11. interface slot-number/port-number
12. macro apply cisco-router $NVID number
13. end
14. wr


详细步骤:
 Enters global configuration mode.

	Command or Action	Purpose
Step 1	enable Example: Switch> enable
Step 2	vlan database Example: Switch# vlan database
Step 3	vlan vlan-number name vlan-name Example: Switch(vlan)# vlan 10 name data VLAN 10 modified Name: DATA	Specifies the number and name of the VLAN being configured. • vlan-number―Unique value that you assign to the dial-peer being configured. Range: 2 to 1004. • name―Name of the VLAN to associate to the vlan-number being configured.
Step 4	vlan vlan-number name vlan-name Example: Switch(vlan)# vlan 100 name voice VLAN 100 modified Name: VOICE	Specifies the number and name of the VLAN being configured.
Step 5	exit Example: Switch(vlan)# exit	Exits this configuration mode.
Step 6	wr Example: Switch# wr	Writes the modifications to the configuration file.
Step 7	configure terminal Example: Switch# configure terminal	Enters global configuration mode.
Step 8	macro global apply cisco-global Example: Switch (config)# macro global apply cisco-global	Applies the Smartports global configuration macro for QoS.
Step 9			interface slot-number / port-number Example: Switch (config)# interface fastEthernet 0/1	Specifies interface to be configured while in the interface configuration mode. • slot-number / port-number―Slot and port of interface to which Cisco IP phones or PCs are connected . Note The slash must be entered between the slot and port numbers.
Step 10	macro apply cisco-phone $AVID number $VVID number Example: Switch (config-if)# macro apply cisco-phone $AVID 10 $VVID 100	Applies VLAN and QoS settings in Smartports macro to the port being configured. • $AVID number―Data VLAN configured in earlier step. • $VVID number―Voice VLAN configured in earlier step.
Step 11	interface slot-number / port-number Example: Switch (config-if)# interface fastEthernet 0/24	Specifies interface to be configured while in the interface configuration mode. • slot-number / port-number ―Slot and port of interface to which the Cisco router is connected . Note The slash must be entered between the slot and port numbers.
Step 12	macro apply cisco- router $NVID number Example: Switch (config-if)# macro apply cisco-router $NVID 10	Applies the VLAN and QoS settings in Smartports macro to the port being configured. • $NVID number―Data VLAN configured in earlier step.
Step 13	end Example: Switch(config-if)# end	Exits to privileged EXEC configuration mode.
Step 14	wr Example: Switch# wr	Writes the modifications to the configuration file.
