VIAVI TestCenter Conformance: ELAN CTS - Parameters show the Same EVC endpoints with different VLANs

• Looking at MEF 10.3, there is something called VLAN ID preservation. It can be enabled or disabled. The CTS has parameter PIXIT_CONFIGURATION.2 which allows the user to enable or disable preservation. Seems the default is disable but when I run a test for example on TC_9_1, the test only passes when the VLAN-ID is preserved. • For example: The CTS  parameters show EVC1_A = VLAN 11, EVC1_B = VLAN 21, EVC1_C = VLAN 31 • If preservation is disabled, I'm thinking we should expect when EVC1_A sends vlan 11, then EVC1_B should expect VLAN 21. (but as mention the test fails) • If preservation is enabled, then EVC1_B should expect VLAN11. (which is what TC_9_1 is doing even though preservation is disabled)
