IF we make a port as a part of vlan all the frames belong to that vlan will be tagged. So even if we make a port as a part of vlan how can we make it as untagged. Whether the ports in VLAN 1, native vlan will be tagged with vlan 1 or it's empty. Which command do we use to untagged the port.
If the port is set to access then the frames are sent untagged. Frames sent on trunk ports are tagged except for the native VLAN by default. It is possible to have different native VLANs on different trunks on the switch.
It is also possible to tag the native VLAN with the vlan dot1q tag native command.
And the commands to make the ports tagged and untagged is "Switch port mode trunk" for tagged and "switch port mode access" for un tagged port right ? in cisco switches or do we need to add any other commands.
Encapsulation does not need to be set if switch only supports Dot1q, older devices support ISL as well. The port can also be set to dynamic desirable or auto but if you want a trunk it is better to hard code it.
Switch also use Dynamic Trunking Protocol (DTP). This can be turned off with switchport nonegotiate if you don't want it enabled. Then it's also possible to change the native VLAN if wanted and it's also possible to tag the native VLAN.
switchport mode access
switchport access vlan x
To confirm which mode the port is configured for and what mode it's actually running in use the show interface x/x switchport command.
