常用的基本操作
进入特权模式
config
端口连接状态
show interface brief
查看当前配置
show running-config
端口拆分和恢复
400G 拆分成 200G
bash
config
split interface FH0/1400G 拆分成 200G后恢复400G
bash
no split interface FH0/1使能端口
bash
no shutdown丢包查看
bash
show interfaces FH0/1 counters drops查看ecn相关
查看队列是否使能ecn
bash
show qos ecn int FH0/2
查看ecn计数
bash
show qos wred-ecn statistics int FH0/2
添加vlan
bash
interface FH0/1
interface range FH0/1-10
switchport access vlan 10400Gbps交换机的推荐配置
假设使用优先级 5 来承载分布式存储的 RoCEv2 流量。在交换机里，各个面板端 口需要针对优先级 5 使能 PFC 流控，命令行如下。
bash
mtu forwarding 9000
ip-ref-load-balance-profile default
ipv4 field protocol src-ip dst-ip l4-src-port l4-dst-port
