Purpose
Enters global configuration mode.
Creates a bridge group number and specifies a protocol.
Associates a CoS value with the Layer 2 tunneling port. Valid numbers
for a cos-value range from 0 to 7.
Enters interface configuration mode for the interface to be configured
as a tunnel port.
Assigns a bridge group to the interface.
Sets the interface as an IEEE 802.1Q tunnel VLAN.
Sets the interface as a Layer 2 protocol tunnel port and enables all
three protocols or specifically enables CDP, STP, or VTP. These
protocols are off by default.
Returns to privileged EXEC mode.
Displays the tunnel ports on the switch.
(Optional) Saves your entries in the configuration file.
Purpose
Enters global configuration mode.
Creates a bridge group number and specifies a protocol.
Associates a CoS value with the Layer 2 tunneling VLAN. Valid
numbers for a cos-value range from 0 to 7.
Enters subinterface configuration mode and the subinterface to be
configured as a tunnel VLAN.
Sets the subinterface as an IEEE 802.1Q tunnel VLAN.
Assigns a bridge group to the interface.
Returns to privileged EXEC mode.
(Optional) Saves your entries in the configuration file.
