show interface status命令仅显示访问VLAN，而不显示语音VLAN。对命令的建议是否有建议，以专门显示分配给交换机端口的语音VLAN，而无需使用过多的正则表达式或查找正在运行的配置？
#1 楼
首先，请注意：我不确定为什么要指定以下内容（强调我的意思），关于命令的任何建议，这些命令要专门显示分配给交换机端口的语音VLAN，而无需使用
，通过
alias命令可以缩短Cisco设备中最长的reg-ex命令。实际上，我经常使用的别名之一就是显示您要查找的确切信息。现在，我将在下面进行介绍。现在，有几种方法可以获取您要查找的信息，这取决于您确切地知道什么以及您想要做什么。查找。
如果您知道该特定交换机上的语音VLAN，并且正在寻找分配给它们的端口，则只需发出以下命令：
show vlan id <voice-vlan-number>
这将为您提供使用该VLAN的所有端口的列表：
ATR4506-A1A-1#show vlan id 210
VLAN Name Status Ports
---- -------------------------------- --------- -------------------------------
210 ATRIUM-IP-PHONES active Gi2/2, Gi2/3, Gi2/4, Gi2/5, Gi2/6,
如果您知道感兴趣的端口（或想要查看所有端口），并且只想查看该端口上正在使用哪个语音VLAN，则需要查找以下内容：
show interfaces switchport | include Name|Voice
我将此命令别名为
svv（用于显示语音VLAN），如下所示：conf t
alias exec svv show interfaces switchport | include Name|Voice
这是我最常使用的命令收集此信息，然后输出：
ATR4506-A1A-1#svv
Name: Te1/1
Voice VLAN: none
Name: Te1/2
Voice VLAN: none
Name: Gi2/2
Voice VLAN: 210 (ATRIUM-IP-PHONES)
Name: Gi2/3
Voice VLAN: 210 (ATRIUM-IP-PHONES)
Name: Gi2/4
Voice VLAN: 210 (ATRIUM-IP-PHONES)
Name: Gi2/5
Voice VLAN: 210 (ATRIUM-IP-PHONES)
另一种选择是过滤
show run如果需要确切的接口名称和切换端口信息（例如，出于脚本目的），则输出：show running-config | include interface GigabitEthernet|switchport voice vlan
这给出：
ATR4506-A1A-1#show running-config | include interface GigabitEthernet|switchport voice vlan
interface GigabitEthernet1/3
interface GigabitEthernet1/4
interface GigabitEthernet1/5
interface GigabitEthernet1/6
interface GigabitEthernet2/1
interface GigabitEthernet2/2
switchport voice vlan 210
interface GigabitEthernet2/3
switchport voice vlan 210

show interfaces <interface> switchport或show interfaces <interface> switchport | i Voice会为您提供所需的东西。Switch# show interfaces gigabitethernet0/1 switchport
