NCS540 l2transport vlan ranges.

Hello,

Is there any way around limitation for several vlan-range on l2transport subinterface?

Platform: N540-ACC-SYS

IOS-XR: 7.1.1

!! APPLY ERRORS: This configuration was accepted by the system,
!! but errors occurred when the system attempted to make the
!! configuration operational. The individual errors for each
!! failed configuration command can be found below. These errors
!! will cause an inconsistency between the system's running
!! configuration and its operational state, which may be addressed
!! by using the 'no' form of the command to remove it from the
!! running configuration.

Re: NCS540 l2transport vlan ranges.

It is apparently impossible...

L2VPN and Ethernet Services Configuration Guide for Cisco NCS 540 Series Routers, IOS XR Release 7.0.x

Restrictions and Limitations
To configure VLAN sub-interface, the following restrictions are applicable.
• For double tagged packet, the VLAN range is supported only on the inner tag.
• VLAN list is not supported.
VLANs separated by comma is called a VLAN list. See the example below.
Router(config)#interface tenGigE 0/0/0/2.0 l2transport
Router(config-subif)#encapsulation dot1q 1,2 >> VLAN range with comma
Router(config-subif)#commit
• If 0x9100/0x9200 is configured as tunneling ether-type, then dot1ad (0x88a8) encapsulation is not
supported.
• If any sub-interface is already configured under a main interface, modifying the tunneling ether-type is
not supported.
• You can program a maximum number of 16 virtual MAC addresses on your router.
