核心是4506,下联2960,和3500XL,vlan 的划分直接在4506 的口上,2960和3500Xl直接接在相应的口上,但发现2960的控制台抱错:native vlan mismatch 之类的
An 802.1Q native vlan is defined as one of the following 1. The vlan a port is in when not in trunking operational mode:o:EF&XK;j:nV2L 2. The vlan from which Layer 2 frames will be transmitted untagged on an 802.1Q trunk portk6d2T}vUc} 3. The vlan to which Layer 2 frames will be forwarded is received untagged on an 802.1Q trunk port With an 802.1Q native vlan, a switch can forward any Layer 2 ...
Keywords: 802.1Q native vlan Inter-vlan Routing Show trunk Management vlan 之间的路由(Inter-vlan Routing,这里简写为IVR)好象很简单,不过也有些窍门。比如一个常见的错误是使用802.1Q封装时,交换引擎与路由器之间的TRUNK两端的native vlan不匹配。如Catalyst 4006交换机与其路由模块WS-C4232_L3之间就使用802.1Q的TRUNK封装,在交换引擎上用set vlan 1 3/1设置trunk的native vlan,用show trunk命令查看;在L3模块上用enc do...
以前没接触过cisco,都是作别的厂商。现在改作cisco了,以前做的其他厂商,都是untag/tag来配vlan. 做了个针对native vlan的实验. share一下 S1-port24-------------------port24-S2 S1#sho running-config ! hostname S1 vtp mode transparent ip routing ! vlan 100,200-201 interface FastEthernet1/0/24 switchport trunk encapsulation dot1q switchport trunk native vlan 100 switchport mode trunk ! interface vlan1 ...

cisco的native vlan和vlan有什么不同 请问如下的语句是什么意思: 封装802.1q的trunk端口可以接受带标签和不带标签的数据流,交换机向native vlan 传送不带标签的数据流 以上的带标签和不带标签有什么区别
