Chapter 5 Creating a FlexUNI/EVC ATM-Ethernet Interworking Policy
Setting the Interface Attributes
Step 14 Specify the type of VLAN Translation for this policy 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 For detailed coverage of setting up VLAN translation, see Appendix C, “Setting Up VLAN
Translation.”
Note VLAN translation is only supported on links that are specified as non-FlexUNI at the service
request level.
Step 15 Enter the MTU Size in bytes.
The maximum transmission unit (MTU) size is configurable and optional. The default size is 9216, and
the range is 1500 to 9216. ISC does not perform an integrity check for this customized value. If a service
request goes to the Failed Deploy state because this size is not accepted, you must adjust the size until
the Service Request is deployed.
In ISC 6.0, different platforms support different ranges.
For the 3750 and 3550 platforms, the MTU range is 1500 to 1546.
For the Cisco 7600 Ethernet port, the MTU size is always 9216. Even with the same platform and
same IOS release, different line cards support the MTU differently. For example, older line cards
only take an MTU size of 9216 and newer cards support 1500 to 9216. However, ISC 6.0 uses 9216
in both cases.
For the Cisco 7600 SVI (interface VLAN), the MTU size is 1500 to 9216.
Step 16 Check the PW Tunnel Selection check box if you want to be able to manually select the Traffic
Engineering (TE) tunnel for the pseudowire connecting point-to-point N-PEs.
