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