如何在Cisco交换机上配置语音VLAN

julley

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