qinq-fixed-tag-value
Syntax qinq-fixed-tag-value tag-value
no qinq-fixed-tag-value
Context config>service>egress-multicast-group>sap-common-requirements
Description This command configures the fixed tag value used for QinQ encapsulation.
Default
no qinq-fixed-tag-value
Parameters
tag-value — Specifies the provisioned common value of the fixed 802.1Q tag of all the QinQ SAP's
dot1q-etype
Syntax dot1q-etype [0x0600..0xffff]
no dot1q-etype
Context config>service>egress-multicast-group>sap-common-requirements
Description
This command specifies the dot1q EtherType that must exist on the SAP's access port to allow the
SAP membership within the egress-multicast-group. The config>port>ethernet>access>dot1q-
etype command is used to define the EtherType used when encapsulating a packet with a dot1q tag on
the Ethernet port. Any valid EtherType is allowed on the port.
If the current encap-type for the egress-multicast-group is set to null, the dot1q-etype EtherType is
ignored when evaluating SAP membership in the group. If the encap-type is set to dot1q (the default),
a member SAP's access port must be configured with the same dot1q-etype EtherType as the egress-
multicast-group.
If at least one SAP is currently a member of the efficient-multicast-group, the dot1q-etype value
cannot be changed within the sap-common-requirements node. If the efficient-multicast-group does
not contain any member SAPs, the dot1q-etype value may be changed at any time.
If an access port currently has SAPs associated with it that are defined within an egress-multicast-
group and the port is currently set to encap-type dot1q, the dot1q-etype value defined on the port
cannot be changed.
The no form of the command returns the egress-multicast-group dot1q EtherType to the default value
of 0x8100. If the current encap-type is set to a value other then 0x8100, the command cannot be
executed when SAPs exist within the egress-multicast-group.
Default
The default dot1q-etype is 0x8100 for an egress-multicast-group.
Parameters ethertype — Defines the dot1q EtherType that must be associated with a SAP's access port when the
7750 SR OS Services Guide
in this egress multicast group.
The value 0 is used to indicate that the actual value of the fixed tag will be defined implicitly
by the corresponding tag of the first SAP added to this egress multicast group.
Values

encap-type is set to dot1q. Any valid EtherType may be specified.
Values
