Chapter 4 Managing a FlexUNI/EVC Ethernet Service Request
Setting the Service Request Details
Step 14 Check the Match Inner and Outer Tags check box to enable service requests created with the policy
to match both the inner and outer VLAN tags of the incoming frames.
If you do not check this check box, service requests created with the policy will match only the outer
VLAN tag of the incoming frames.
Checking the Match Inner and Outer Tags attribute causes the Inner VLAN ID and Outer VLAN ID
fields (covered in the next steps) to appear.
Step 15 If the Match Inner and Outer Tags check box is checked, enter the inner and outer VLAN tags in the
Inner VLAN ID and Outer VLAN ID fields.
Usage notes:
• You can specify single values, single ranges, multiples values, multiple ranges, or combinations of
these. Examples:
– 10
– 10, 15,17
– 10-15
– 10-15,17-20
– 10,20-25
• If the Inner VLAN Ranges attribute is set to true in the policy, the Inner VLAN ID field can take a
range of inner VLAN tags.
Step 16 If the Match Inner and Outer Tags check box is unchecked, enter the outer VLAN tag in the Outer
VLAN ID field.
Note The VLAN specified in Outer VLAN ID will be provisioned on the rest of the L2 access nodes (if the
link has any), including the customer-facing UNI.
Step 17 In the VLAN Rewrite section of the window, choose a Rewrite Type from the drop-down list.
The choices are:
• Pop
• Push
• Translate
The subsequent attributes in the GUI change depending on the choice of Rewrite Type, as covered in the
next steps.
Step 18 If Pop is the Rewrite Type, two check boxes appear:
a. Check the Pop Outer Tag check box to pop the outer VLAN ID tag of the incoming frames that
fulfill the match criteria. If this check box is unchecked, the outer tag of the incoming traffic will
not be popped.
b. Check the Pop Inner Tag check box to pop the inner VLAN ID tag of the incoming frames that
fulfill the match-criteria. If this check box is unchecked, the inner tag will not be changed.
Note that if Pop Inner Tag is checked, Pop Outer Tag is automatically checked.
