Port mode |
该 access 模式是默认端口模式，与单个 VLAN 配合使用。端口模式也可以 trunk是，它接受来自其他交换机上多个 VLAN 的标记数据包。第三个端口模式值是 tagged-access，它接受来自接入设备的标记数据包。 |
detail |
Reflective Relay Status |
反射中继允许数据包对上游和下游流量使用相同的接口。配置反射中继时，始终显示 enabled 状态。未配置反射中继时，此条目不会出现在命令输出中。 |
detail |
Ether type for the interface |
以太类型是以太网帧中的两个八位字段，用于指示哪些协议封装在传入以太网数据包的有效负载中。802.1Q 数据包和 Q-in-Q 数据包都使用此字段。此特定字段显示的输出指示接口的以太类型，用于匹配传入 802.1Q 数据包和 Q-in-Q 数据包的以太类型。该接口的传出 802.1Q 和 Q-in-Q 数据包中也添加了指示的以太类型字段。 |
detail |
VLAN membership |
属于此接口的 VLAN 名称。 |
无， briefdetail |
Tag |
802.1Q 标记的数量。 |
无， briefdetail |
Tagging |
指定接口是转发 802.1Q tagged 还是 untagged 信息流。 |
