1、查看当前VLAN信息show vlan brief
root@sonic:/home/adminadmin# show vlan brief
+-----------+--------------+------------+----------------+-----------------------+-------------------+
| VLAN ID | IP Address | Ports | Port Tagging | DHCP Helper Address | Port Admin/Oper |
+===========+==============+============+================+=======================+===================+
| 10 | | Ethernet53 | untagged | | up/down |
| | | Ethernet54 | untagged | | up/down |
+-----------+--------------+------------+----------------+-----------------------+-------------------+
2、查看端口信息show interfaces status | grep QSFP
root@sonic:/home/adminadmin# show interfaces status | grep QSFP
Ethernet49 77,78,79,80 100G 9194 rs 100GE1/0/49 routed up up QSFP28 or later N/A
Ethernet50 85,86,87,88 100G 9194 rs 100GE1/0/50 routed up up QSFP28 or later N/A
Ethernet51 93,94,95,96 100G 9194 rs 100GE1/0/51 routed up up QSFP28 or later N/A
Ethernet52 97,98,99,100 100G 9194 rs 100GE1/0/52 routed up up QSFP28 or later N/A
3、创建VLAN or 删除VLAN
config vlan add 11
config vlan del 11
4、给端口添加VLAN信息
config vlan member add 11 Ethernet50 -u
（如果是蛇形打流的话，TC-->49-->50-->51-->52-->TC）
需要把50,51两个端口配成一个VLAN，49,52两个端口配成一个VLAN。
5、保存配置信息
config save
6、应用当前信息
config reload
5、删除端口VLAN信息，同理，删除之后，需要再次保存配置信息
config vlan member del 11 Ethernet50
6、sonic下，设备端口配置信息，都是通过JSON文件来保存的，也可以通过修改JSON文件的方式来配置端口
JSON文件路径：/etc/sonic/config_db.json
7、查看端口流量计数
show interfaces counters | grep U
清空计数
sonic-clear counters
8、查看模块信息
show interfaces transceiver eeprom -d
