Note: switchport mode trunk can run directly on the 2950 switch, which enables 802.1q directly. To enable the relay function on vswitches such as 3550 and 4500, you must first select the encapsulation method, that is, run switchport trunk encapsulation dot1q.Sw0 # vlan databaseSw0 (vlan) # vtp domain ContosoSw0 (vlan) # vtp password ContosoSw0 (

The VLAN mentioned here is a VLAN that complies with the IEEE 802.1Q standard.The frame structure is as follows:|da|sa|tag| type| date| crc|VLAN frames Add a 4byte long tag field to the source MAC address, relative to normal Ethernet frames. This field is specifically divided into:| tpid|priority| cfi| Vlan id|Tpid:tag

Cisco single-ARM routing configurationOne-arm routing, which is to set up multiple logical subinterfaces on the router, one VLAN for each sub-interface. The data on each sub-interface is passed on the physical link to be labeled encapsulated. Cisco devices support ISL and 802.1q (dot1q) protocols. Huawei only supports 802.1q.The difference between dot1q and ISL: dot1q is a generic VLAN protocol model for va
