Catalyst VLAN QOS

[divadko]

Hi all,

I have connected 2 switches WS-C3650-24TS and C9200L-24T-4G via 800meg radio link with trunk.I am trunking 2 vlans ... Vlan 30 for IPTV and vlan 50 for Internet.I need to make a prioritization for VLAN30 to prevent video issues when overall traffic reaches maximum radio link capacity.Any idea how to solve it? I never done it before.Thanx for help.

you can try bellow example  from my notes :

class-map CM30
match vlan 30
!
policy-map PM30
class CM30
priority level 1
!
interface gigabitethernet x/x << change this trunk port ?
service-policy input PM30
service-policy output PM30

Still has issue refer below threads :

if you doing Cat 9200 bit different :

Isnt there needed any advanced configurations based on that the uplink is only 800megs not full gig?

Yes, you want to "shape" for your available bandwidth, and then have QoS management on the shaped traffic.

W/o my checking, I don't know what "shaping" features the 3650 or 9200 have.  I know the earlier 3560/3750 had a port "shape" feature, although it was inexact.
