Chapter 3 Creating a FlexUNI/EVC Ethernet Policy
Setting the FlexUNI Attributes
manually-specified VLAN is already in use in the access domain delimited by the FlexUNI, ISC will
display an error message indicating that the new VLAN ID being specified is already in use on the NPC.
The operator will be prompted to specify a different VLAN ID, which will be provisioned on the L2
access nodes.
Step 6 Check the AutoPick Bridge Group Name check box to have ISC autopick the group name for the
service request during service request creation.
If this check box is unchecked, the operator will be prompted to specify a group name during service
request creation. If the check box is checked, the group name will default to the customer name.
Note This attribute is applicable only for supported IOS XR devices.
Step 7 Check the AutoPick Bridge Domain Name check box to have ISC autopick the domain name for the
service request during service request creation.
Usage notes:
• If this check box is unchecked, the operator will be prompted to specify a domain name during
service request creation.
• If the check box is checked, the domain name will default to the following format:
– For pseudowire and local connect core types: ISC-Job-Job_ID, where Job_ID is the service
request job ID.
– For VPLS core type: ISC-VPN_Name-VPN_ID, where VPN_Name is the name of the VPLS
VPN being used, and VPN_ID is the VPN ID used in the service request.
Note This attribute is applicable only for supported IOS XR devices.
Step 8 Continue with the steps contained in the next section, Setting the VLAN Matching Criteria Attributes,
page 3-13 .
Setting the VLAN Matching Criteria Attributes
Prior to the introduction of the FlexUNI capability, service providers could either deploy
service-multiplexed services (ERS/ERMS or EVPL/EVCS) or service-bundled services on a single port.
Both could not be supported simultaneously due to the limitations in the infrastructure, which only
allowed matching the outer-most VLAN tag.
One of the key benefits of FlexUNI/EVC support in ISC is to provide a flexible means to examine the
VLAN tags (up to two levels) of the incoming frames and associate them to appropriate Ethernet Flow
Points (EFPs). This allows service providers to deploy simultaneously both the service-multiplexed and
service-bundled services on a single port.
To set the FlexUNI VLAN matching criteria attributes, perform the following steps.
Step 1 Check the Both 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.
