我有一台 Cisco SG200-50 50 端口交换机，我想对其进行配置，以便有一个大的 LAN（交换机上的所有计算机都可以互相看到），但一半的计算机只能看到第一个网关，而一半的计算机只能看到另一个网关（即，插入左侧的计算机获得网关 1，插入右侧的计算机获得网关 2）。
这是当前配置（针对 3 个网关），在我胡乱操作之后。

答案1
更新：我想我明白你在问什么，希望这个答案会更有用一些。
本质上，您需要做的是使交换机前半部分的 VLAN 可供交换机后半部分访问。
应该有办法将此 VLAN 添加到您想要同时访问这两个网络的端口。由于您只想使用一个网络，我们将配置“网络A“以访问整个交换机。
从命令行（您可以通过 SSH 连接到交换机吗？）它看起来像这样：
conf t
int gigabitethernet1-gigabitethernet24
switchport access vlan 101
switchport access vlan 201
exit
这会将交换机的前半部分分配给网络 A (vlan 201)，并告知其使用路由器 A (vlan 101)。您可以对交换机的后半部分执行类似操作。
int gigabitethernet25-gigabitethernet50
switchport access vlan 102
switchport access vlan 201
exit
这会将交换机的另一半分配给网络 A（vlan 201），并告诉它使用路由器 B（vlan 102）。
这应该可以满足要求，或者至少可以让你朝着正确的方向前进，但我强烈建议你在对交换机进行任何更改之前，请务必测试此配置！
这组相同的步骤可以通过 Web GUI 完成，因此想法仍然相同，但过程略有不同。希望对您有所帮助。
