Configuring the Protocol Type Value for the Outer VLAN Tag
The tag protocol identifier (TPID) field of the S-Tag is user-configurable.
To set the S-Tag TPID, use the following command.
Select a value for the S-Tag TPID.
CONFIGURATION mode
vlan-stack protocol-type
The default is 9100.
To display the S-Tag TPID for a VLAN, use the show running-config command from EXEC privilege mode. Dell EMC
Networking OS displays the S-Tag TPID only if it is a non-default value.
Configuring Dell EMC Networking OS Options for Trunk Ports
802.1ad trunk ports may also be tagged members of a VLAN so that it can carry single and double-tagged traffic.
You can enable trunk ports to carry untagged, single-tagged, and double-tagged VLAN traffic by making the trunk port a hybrid
port.
To configure trunk ports, use the following commands.
1. Configure a trunk port to carry untagged, single-tagged, and double-tagged traffic by making it a hybrid port.
INTERFACE mode
portmode hybrid
2. Add the port to a 802.1Q VLAN as tagged or untagged.
INTERFACE VLAN mode
[tagged | untagged]
In the following example, twentyfiveGigE 1/1 is a trunk port that is configured as a hybrid port and then added to VLAN
100 as untagged VLAN 101 as tagged, and VLAN 103, which is a stacking VLAN.
DellEMC(conf)#interface TwentyfiveGigE 1/1
DellEMC(conf-if-tf-1/1)#portmode hybrid
DellEMC(conf-if-tf-1/1)#switchport
DellEMC(conf-if-tf-1/1)#vlan-stack trunk
