如何在Cisco交换机上配置语音VLAN

http://blog.chinaunix.net/uid-261392-id-2138837.html

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 namevlan-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 namevlan-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 $AVIDnumber $VVIDnumber

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.

•$AVIDnumber—Data VLAN configured in earlier step.

•$VVIDnumber—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 $NVIDnumber

Example:

Switch (config-if)# macro apply cisco-router $NVID 10

 

Applies the VLAN and QoS settings in Smartports macro to the port being configured.

•$NVIDnumber—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.
