Chapter 5 Creating a FlexUNI/EVC ATM-Ethernet Interworking Policy

Setting the Interface Attributes

Step 6

Check the Translate Inner check box to allow the operator to specify a target inner VLAN ID during
service request creation.

The inner tag of all the incoming frames that fulfill the match criteria are translated to this ID. If the
check box is unchecked, no inner tag translation is performed. See

Table 5-1

.

Note

Table 5-1

summarizes the realization of different VLAN translations available in the FlexUNI/EVC

infrastructure. The second and third columns (Match Outer Tag and Match Inner Tag) refer to policy
settings. The last two columns (Translate Outer Tag and Translate Inner Tag) indicate the VLAN
translation that occurs on the incoming frames.

Step 7

Click Next.

The EVC Policy Editor - Interface Attribute window appears, as shown in

Figure 5-4

.

Step 8

Continue with the steps contained in the next section,

Setting the Interface Attributes, page 5-12

.

Setting the Interface Attributes

This step of creating the FlexUNI/EVC ATM-Ethernet Interworking policy involves setting the interface
attributes, as shown in the EVC Policy Editor - Interface Attribute window in

Figure 5-5

. The attributes

you can configure in this window are grouped under the following categories:

N-PE/U-PE information

Speed and duplex information

ACL name and MAC addresses

UNI port security

Storm control

L2 protocol tunneling

In some cases, checking an attribute causes additional attributes to appear in the GUI. This is covered in
the steps that follow.

Note

If the CE is directly connected to an N-PE, only speed, duplex, UNI shutdown, and other generic options
are presented. In this case, port security, storm control, L2 protocol tunneling, and other advanced
features are not supported due to the current platform limitations. If these features are needed for a
service, the service provider must deploy Layer 2 Ethernet access nodes beyond the FlexUNI to support
these requirements.
