NCS540 l2transport vlan ranges.

[Alexander Rodionov]

Hello,

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

It is apparently impossible...

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.
