Cisco 3850 Trunk

[RaulSambula40179]

Can Cisco 3850 support the same VLAN on different Sub interfaces?

Can you explain what you're trying to do? What you've asked isn't making sense to me.

We're trying to fix a problem we have. I believe subinterfaces provide us with more capability when there's not enough ports to connect to.

Hi there,

The 3850 does not support sub-interfaces. It does support SVIs and multiple trunk interfaces can be configured with the same tagged VLANs.

!
vlan 10
!
int vlan 10
  ip address 192.168.0.254 255.255.255.0
!
int gi1/0/1
  switchport
  switchport mode trunk
  switchport trunk allowed vlan add 10
!
int gi1/0/2
  switchport
  switchport mode trunk
  switchport trunk allowed vlan add 10
!

cheers,

Seb.
