Configuring S-VLANs over Bridged Ethernet

Configuring S-VLAN Subinterfaces over Bridged Ethernet

Use the optional keyword untagged to specify that frames be sent untagged. The
keyword is valid only for VLAN ID 0. It allows tagged frames to be received, but sends
out untagged frames.
Example
host1(config-subif)#vlan id 400
There is no no version.
See vlan id.
S-VLANs over bridged Ethernet support the same set of higher-level protocols as VLANs
over bridged Ethernet. You configure S-VLANs over bridged Ethernet in the same way
that you configure VLANs over bridged Ethernet, with the addition of certain commands.
Like VLANs, configuring S-VLANs over bridged Ethernet interfaces consists of two basic
tasks:
Configure the layers up to and including the S-VLAN subinterface.
1.
Configure the higher-level protocols above the S-VLAN subinterface.
2.
Before you can remove an S-VLAN subinterface, you must remove the upper-layer
interface stack.
NOTE: S-VLAN oversubscription is not supported on bridged Ethernet interfaces.
For more information about specifying ATM interfaces and subinterfaces, see Interface
Types and Specifiers in JunosE Command Reference Guide.
To configure an S-VLAN subinterface over bridged Ethernet:
Create an ATM 1483 subinterface and associated PVC.
1.
host1(config)#interface atm 3/1.1
host1(config-subif)#atm pvc 1 5 33 aal5snap 0 0 0
Specify bridged Ethernet as the encapsulation method for the ATM 1483 subinterface.
2.
host1(config-subif)#encapsulation bridge1483
Create a VLAN major interface by specifying VLAN as the encapsulation method for
3.
the bridged Ethernet interface.
host1(config-subif)#encapsulation vlan
Create a VLAN subinterface to carry the higher-level protocols by adding a
4.
subinterface number to the interface identification command.
host1(config-subif)#interface atm 3/1.1.1
