H3C S5500 交换机，用 reset save 恢复出厂设置后，没了 port link-mode bridge 这个命令！查资料得到需要从 3 层降到 2 层。 我原本的需求：划分 vlan 1-10 接光猫，11-15 接路由器。我有 5 台这个交换机，别的都有，就这台机器没。我怎么才能降级

 | 1 tammy Mar 3, 2021 你就不能打客服电话么，客服电话一会解决了 |
 | 2 order Mar 3, 2021 你看一下端口能不能 port access vlan xxx，你应该是恢复出厂设置版本的原因，S5500 系列 EI 应该是具有端口 route 和 bridge 两个模式，SI 应该是只有二层 bridge 模式，看一下型号，如果是 SI 应该就是版本显示的原因，不用深究，划分 vlan 即可 |
| 3 order Mar 3, 2021 或者你全局模式下[xxx]dis inter g 1/0/1，我看一下端口信息 |
 | 4 smallfount Mar 3, 2021 直接配个 access vlan 上去就行了。。。 默认不会用 route 口的 |
 | 5 jousca Mar 3, 2021 是不是你的语法错了。 请看范例。 [举例] # 设置 GigabitEthernet1/0/1 至 GigabitEthernet1/0/5 为二层端口。 <Sysname> system-view [Sysname] port link-mode bridge GigabitEthernet 1/0/1 to GigabitEthernet1/0/5 # 设置 GigabitEthernet1/0/1 至 GigabitEthernet1/0/5 为三层端口。 <Sysname> system-view [Sysname] port link-mode route GigabitEthernet 1/0/1 to GigabitEthernet1/0/5 |
| 6 jousca Mar 3, 2021 还有就是把固件刷一下。刷个最新版本的看看。 |
