Configuring VLAN Stacking Configuring Service-Based VLAN Stacking
OmniSwitch 6800/6850/9000 Network Configuration Guide March 2008 page 6-17
Changing the VLAN Stacking Mode
The VLAN Stacking legacy (port-based) mode is active on the switch by default. To change the current
mode, use the ethernet-service mode command. For example, the following command specifies the
service mode, which is required for configuring VLAN Stacking services:
-> ethernet-service mode service
Note. Changing the VLAN Stacking mode is not allowed if there is an existing VLAN Stacking or IP
Multicast VLAN configuration on the switch. Remove any existing configuration of these two features
before attempting to change the mode.
Use the show ethernet-service mode command to determine which mode is active for the switch.
Configuring SVLANs
There are three kinds of SVLANs: one that carries customer traffic, one that carries provider management
traffic, and one that carries IP Multicast VLAN traffic (IPMVLAN). SVLANs are not configurable or
modifiable using standard VLAN commands. The exception to this is that it is possible to configure an IP
interface for a provider management SVLAN. However, traffic is not routed on this interface.
The ethernet-service command is used to create an SVLAN. This command provides parameters to spec-
ify the type of SVLAN: svlan (customer traffic), management-vlan (provider management traffic), or
ipmv (IP Multicast traffic). For example, the following commands create a customer SVLAN, manage-
ment SVLAN, and IP Multicast VLAN:
-> ethernet-service svlan 300
-> ethernet-service management-vlan 200
-> ethernet-service impv 500
Similar to standard VLANs, the administrative and Spanning Tree status for the SVLAN is enabled by
default and the SVLAN ID is used as the default name. The ethernet-service svlan command also
provides parameters for changing any of these status values and the name. These are the same parameters
that are used to change these values for standard VLANs. For example, the following commands change
the administrative and Spanning Tree status and name for SVLAN 300:
-> ethernet-service svlan 300 disable
-> ethernet-service svlan 300 stp disable
-> ethernet-service svlan 300 name “Customer A”
To delete an SVLAN from the switch configuration, use the no form of the ethernet-service svlan
command. For example, to delete SVLAN 300 enter:
-> no ethernet-service svlan 300
Note that when an SVLAN is deleted, all ports associations with the SVLAN are also removed.
Use the show ethernet-service vlan command to display a list of VLAN Stacking VLANs configured for
the switch.
