QoS with Frame Relay, what is correct?

[jesusdavidzambrano]

Hi,

I have to configure QoS in a router, but, I don't know the correct form:

1st option.

interface Serial0/0.1 point-to-point
ip address 192.168.10.2 255.255.255.252
frame-relay interface-dlci 300
  class DATA

map-class frame-relay DATA
no frame-relay adaptive-shaping
frame-relay cir 64000
frame-relay bc 640
frame-relay be 0
frame-relay mincir 64000
service-policy output DOUBT

2nd Option.

interface Serial0/0.1 point-to-point
bandwidth 128
ip address 192.168.10.2 255.255.255.252
service-policy output DOUBT
frame-relay interface-dlci 300

What´s the diference, what's correct or wrong?

Regards,

(excuse my bad english)

Option 1, since your DLCI 300 is only allocated 64k bandwidth (interface bandwidth is 1536k), to ensure traffic is not going to drop by the provider, traffic should be shaped be the inner QoS policy.
