一、主机管理接口,管理员可以利用该接口管理交换机 二、网关接口,用于三层交换机跨vlan间路由,具体可以用interface vlan接口位置命令来创建SVI,然后为其配置IP地址即可实现路由功能。 创建SVI接口的方法 1. 创建vlan 10 2. interface vlan 10 3. ip add access:接终端(1个vlan) trunk:承接vlan 当一条链路,需要...
where the user first creates a VLAN subinterface, and then configures that VLAN in subinterface configuration mode. To create an Attachment Circuit, you need to include thel2transportkeyword in the interface command string to specify that the i...
In a typical deployment of VLAN mapping, you want service provider to provide a transparent switching infrastructure that includes customers’ switches at the remote location as a part of local site. This allows customers to use the same VLAN ID space ...
4) finally the default gateway of the vlan 10 clients should point to the 3750 L3 vlan 10 interface. Note, if you do not want to readdress the firewall interface then you can use the existing vlan 10 subnet for the connection from the 3750 to the firewall and then use a new IP su...
Cisco Discovery Protocol (CDP) Per VLAN Spanning Tree Plus (PVST+) Dynamic Trunking Protocol (DTP) Device Link Detection Protocol (DLDP) You can select one or more Layer 2 protocols. user-defined-protocolprotocol-name Sets the drop threshold of packets of a user-defined Layer 2 protocol.p...
hello we have a 3750 cisco switch , need to built a setup with 2 vlans vlan 10 with subnet 172.16.20.0/24 gateway ip address is 172.16.20.1 which is on firewall which is connected to uplink port eth 1/1 on 3750 vlan 20 10.10.10.0/24 with gateway 10.10.10.1 on this 3750 switch...

要求无线 AP 和 WLC 在同一个 vlan,并且只支持 cisco 410x and 440x 系列 WLC和 cisco 1000系列无线AP.在其它无线 AP 和 WLC 不支持。 Layer 3 Transport Mode Layer 3 LWAPP Control and Data messages 都被封装成 UDP packet.这种传输模式比 layer 2 有更好的扩展性和灵活性。Layer 3 LWAPP cisco 所...
避免任意使用默认的VLAN 1 将Access的端口配置成access模式,避免终端协商成trunk模式;关闭trunking协商(DTP)功能(交换机端口协商) 使用端口安全功能限制端口上可习得的MAC地址数量 为STP开启BPDU保护和根保护功能 关闭连接着不可信或者明显不需要CDP(Cisco Discovery Protocol)功能的网络的端口上的CDP功能。
This post will deal with creating Layer 2 VLANs on Cisco switches and performing all relevant configurations. Up to 4094 VLANs can be configured on Cisco catalyst switches. By default, only VLAN 1 is configured on the switch, so if you connect hosts on a
