Hi there,

What config the switchport uses from switchport access ... and swichport trunk ... is determined by the configured switchport mode ... command.

In this case the switchport mode is access so it will be sending frames untagged from VLAN 215 and placing all untagged frames received into VLAN 215.

cheers,

Seb.

Hi,

As per your configuration, it seems like that this port was configured as Trunk but a letter on you had changed it on the Access mode.

When you will change the mode of a switch port from trunk to access or vise Versa. It will not remove the old commands. You have to remove manually. Currently, this port is working as Administrative Mode: static access and access VLAN is 215.
