Chapter 6 Managing a FlexUNI/EVC ATM-Ethernet Interworking Service Request
Setting the Service Request Details
The choices are:
• DOT1QTRUNK—Configures the UNI as a trunk with 802.1q encapsulation. If the UNI belongs to
a directly connected and FlexUNI link, this setting signifies that the incoming frames are 802.1q
encapsulated and that they match the VLAN ID configured for the link. This specific topology does
not involve a trunk UNI as such.
• DOT1QTUNNEL—Configures the UNI as an 802.1q tunnel (also known as a dot1q tunnel or
• ACCESS—Configures the UNI as an access port.
This attribute allows you to deploy different types of UNI encapsulation on different links of a service.
Step 25 In the PE/UNI Interface Description field, enter a description for the interface, if desired.
Step 26 Check the UNI Shutdown check box if you want to leave the UNI port shut during service activation
(for example, when the service provider wants to deploy a service in the network but wants to activate it
at a later time).
Step 27 Specify the type of VLAN Translation for the service request by clicking the appropriate radio button.
The choices are:
• No—No VLAN translation is performed. (This is the default.)
• 1:1—1:1 VLAN translation.
• 2:1—2:1 VLAN translation.
Note VLAN translation, and all standard UNI and port security attributes are applicable for links with
L2 access. If the UNI is on an N-PE, these attributes will not appear.
Note For detailed coverage of setting up VLAN translation, see Appendix C, “Setting Up VLAN
Step 28 Check the N-PE Pseudo-wire on SVI check box to have ISC generate forwarding commands under SVIs
(switch virtual interfaces).
By default, this check box is not checked. In this case, ISC generates forwarding commands under the
For a FlexUNI link, the attribute N-PE Pseudo-wire on SVI is dependent on the value of the attribute
Configure with Bridge Domain (this is available in the service request workflow in the EVC Service
Request Editor window). N-PE Pseudo-wire on SVI, if enabled, will be reflected only when Configure
with Bridge Domain is set to true. Otherwise, the service request will not be created with xconnect under
SVI, even if N-PE Pseudo-wire on SVI is enabled.
• For a FlexUNI link, the attribute N-PE Pseudo-wire on SVI is dependent on the value of the attribute
Configure with Bridge Domain (in the EVC Service Request Editor window). N-PE Pseudo-wire on
SVI, if enabled, will be reflected only when Configure with Bridge Domain is set to true. Otherwise,
the service request will not be created with scanned under SVI, even if N-PE pseudo-wire on SVI is
• ISC supports a hybrid configuration for FlexUNI/EVC service requests. In a hybrid configuration,
the forwarding commands (such as scanned) for one side of an attachment circuit can be configured
under a service instance, and the xconnect configuration for the other side of the attachment circuit
can be configured under a switch virtual interface (SVI).
