 description ENLACE
 switchport
 switchport trunk encapsulation dot1q
 switchport trunk allowed vlan 800,801,900,901
 switchport mode trunk
 load-interval 30
 wrr-queue cos-map 2 1 1 2 
 wrr-queue cos-map 3 5 3 4 
 wrr-queue cos-map 3 7 6 7 
 rcv-queue cos-map 1 2 1 
 rcv-queue cos-map 1 3 2 
 rcv-queue cos-map 1 4 3 
 rcv-queue cos-map 1 5 4 
 rcv-queue cos-map 1 6 5 
 rcv-queue cos-map 1 7 6
