Hi, List!
I'm trying to map one vlan from another service provider tag 775
to another one because vlan 775 already in use in our network.
!
vlan 775
!
vlan 776
!
vlan 777
!
interface TenGigabitEthernet1/2
description XXXXXXX
switchport trunk native vlan 4094
switchport trunk allowed vlan 777
switchport mode trunk
switchport nonegotiate
switchport priority extend trust
mtu 9198
load-interval 30
storm-control broadcast include multicast
storm-control broadcast level 1.00
storm-control action trap
qos trust extend
spanning-tree portfast trunk
spanning-tree bpdufilter enable
!
Then I add
switchport vlan mapping 775 776
I lost all traffic passing through this port with another vlan tag 777.
#sh vlan mapping
Interface Te1/2:
VLANs on wire Translated VLAN Operation
------------------------------ --------------- --------------
775 776 1-to-1
when I remove this mapping traffic in vlan 777 comes back.
IOS is Cisco IOS Software, Catalyst 4500 L3 Switch Software
(cat4500e-ENTSERVICESK9-M), Version 12.2(54)SG1, RELEASE SOFTWARE (fc1)
I've tryed to google about any known problems but found nothing.
Does anybody knows something about this?
Thanks in advance!

Sincerely yours,
Artem Viklenko.
