QoS output!

anis

Well, as per the QoS configuration guide for cisco catalyst 3560 switch the basic configuration steps are like:

classification

---

policing

---

mark

---

queueing & scheduling

---

Queueing & Scheduling
(1)

---

(2)

---

(3)

---

(4-ingress)

---

(5-egress)

To try this:

Step 1.
I simply created several class-maps traffic each defined by ACL for different types of traffic (as I am not trusting anything)

Step 2/3.
I marked each class-map with a suitable DSCP value. (cos value will be derieved from the global DSCP-COS mapping)

Step 4
I configured the the two ingress queues with mls qos srr-queue input (threshold, dscp-map, cos-map, buffer, bandwidth).

Step 5
I configured the the four egress queues with mls qos srr-queue output (threshold, dscp-map, cos-map, buffer, bandwidth)

Well, i need comment on my understanding of my configuration steps.

Infact after configuring accroding to the steps, the follwoing output (i put different types of traffic on that port) is confusing me:

sw#show policy-map interface fa0/2


FastEthernet0/2
Service-policy input: test_qos

Class-map: map_critical (match-all)
0 packets, 0 bytes
offered rate 0 bps, drop rate 0 bps
Match: access-group name acl_critical

Class-map: map_medium (match-all)
0 packets, 0 bytes
offered rate 0 bps, drop rate 0 bps
Match: access-group name acl_medium

Class-map: map_average (match-all)
0 packets, 0 bytes
offered rate 0 bps, drop rate 0 bps
Match: access-group name acl_average

Class-map: class-default (match-any)
0 packets, 0 bytes
offered rate 0 bps, drop rate 0 bps
Match: any
0 packets, 0 bytes
rate 0 bps

It maybe a small detail but did you enable mls qos globally on the switch?

Queueing and scheduling: I basically followed the auto qos settings:

mls qos map cos-dscp 0 8 16 26 32 46 48 56
mls qos srr-queue input bandwidth 90 10
mls qos srr-queue input threshold 1 8 16
mls qos srr-queue input threshold 2 34 66
mls qos srr-queue input buffers 67 33
mls qos srr-queue input cos-map queue 1 threshold 2 1
mls qos srr-queue input cos-map queue 1 threshold 3 0
mls qos srr-queue input cos-map queue 2 threshold 1 2
mls qos srr-queue input cos-map queue 2 threshold 2 4 6 7
mls qos srr-queue input cos-map queue 2 threshold 3 3 5
mls qos srr-queue input dscp-map queue 1 threshold 2 9 10 11 12 13 14 15
mls qos srr-queue input dscp-map queue 1 threshold 3 0 1 2 3 4 5 6 7

I am looking for anykind of instructin based on this problem.

Check out the Internetwork Expert's CCIE Online Classroom -- they have recorded class sessions at the bottom of that page you can check out, including a CCIE Catalyst QoS class.
