Configuring acceptable-frame-type vlan-tagged on ingress interface
SW1
SW1(config)#interface xe21 | Enter interface configuration mode for xe21 |
SW1(config-if)# switchport mode hybrid acceptable-frame-type vlan-tagged | Configure acceptable-frame-type vlan-tagged |
SW1(config-if)#exit | Exit from interface mode |
SW1(config)#commit | Commit the candidate configuration to the running configuration |
Validation

Now on show vlan brief output we can see that xe21 interface is having port type as tagged (t).
