在网络设备的配置中,"set vlans vlan100 l3-interface vlan.100" 是一条命令,用于将 VLAN 100 配置为 Layer 3 接口。这条命令的作用是将 VLAN 100 与一个 VLAN 接口(通常是一个虚拟接口)关联起来,以便在该接口上进行 Layer 3(网络层)的路由功能。
具体来说,这条命令的含义是将 VLAN 100 设置为一个 Layer 3 接口,并将该接口与 VLAN 100 关联起来。这样,该接口就可以用于处理与 VLAN 100 相关的网络流量,并且可以进行 IP 路由等网络层功能。

passive-interface vlan
"passive-interface vlan" is a command used in Cisco IOS to configure a VLAN interface to be passive for the purpose of routing protocols. When an interface is passive, it will not send any routing updates but will still receive them. This can be useful when you want to control the flow of routing information in your network.
For example, if you have a router that is connected to multiple VLANs and is running a routing protocol such as OSPF, you can configure the VLAN interfaces that you don't want to participate in the routing process as passive. This will prevent unnecessary routing updates from being sent on those interfaces, which can help reduce network congestion and improve performance.

根据您提供的信息,FastEthernet0/1 端口的 `Operational Mode` 的值为 down,这意味着该端口无法正常工作。这可能是由于以下原因之一:
1. 物理连接问题:请检查 FastEthernet0/1 端口和连接到该端口的设备之间的物理连接是否正确。确保网线连接到了正确的端口,并且网线没有损坏或断开。
2. 配置问题:请检查 FastEthernet0/1 端口的 VLAN 配置是否正确。确认端口的 VLAN 号和端口模式是否正确。如果 VLAN10 没有在交换机中创建,则需要先创建 VLAN10。
3. 端口状态问题:请检查 FastEthernet0/1 端口状态是否为开启状态。如果端口状态为关闭或被禁用,则需要将其重新启用。
4. 软件问题:如果上述问题都不存在,则可能是由于交换机的软件问题导致的。请尝试重新启动交换机,并检查是否存在任何错误日志提示。
希望以上建议能够帮助您解决问题。如果问题仍然存在,请提供更多详细信息,以便我可以提供更具体的建议。
