User Guidelines
This command configures the outer VLAN tag type (primary TPID) for
double VLAN tagging when used in global CONFIG mode with the primary-
tpid parameter. Only one outer tag type can be configured for the switch. The
outer tag is added on egress and removed on ingress on uplink (service
provider) ports. Frames normally transmitted untagged (access ports) will
have a single (outer) tag added prior to transmission out of the SP port.
Frames normally transmitted tagged will have an inner tag (the original tag)
and an outer tag (the dvlan tag) added prior to transmission on the SP port.
When used without the primary-tpid parameter, this command configures
the inner VLAN tag type (secondary TPID) for all switch interfaces when
used in global CONFIG mode.
When used in interface mode, this command configures the inner VLAN tag
type (secondary TPID) for an individual switch interface or port channel.
DVLAN capable service provider interfaces must be configured for egress
tagging in order for double tags to be observed on frames egressing the
interface. MAC address learning on DVLAN enabled uplink ports occurs on
the DVLAN port's native VLAN. All participating ports must have the service
provider port PVID configured.
Example
The following example configures two customer ports (Gi1/0/2 and Gi1/0/3
on isolated VLANs 200 and 300) and a single service provider port (Gi1/0/1).
console(config)#vlan 100,200,300
console(config-vlan100,200,300)#exit
!!Configure 0x88A8 as primary TPID.
console(config)#dvlan-tunnel ethertype vman primary-tpid
SP port config
console(config)#interface Gi1/0/1
console(config-if-Gi1/0/1)#exit
console(config-if-Gi1/0/1)#switchport mode general
