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