Re: AW: Adaptive shaping with MQC

Sorry, re-sending with original post.

Thanks a lot.
Now that leads to another question.
If my understanding is correct, only class-default is supported under map-class.

Does this mean it is not possible to apply adaptive shaping selectively?
For example, is it possible to configure as following?
 - Shape HTTP traffic to 128kbps. Reduce the rate down to 64kbps when BECN is recieved.
 - Shape SMTP traffic to 512kbps. Reduce the rate down to 256kbps when BECN is recieved.

Thanks in advance.

Hi,

Even if you want to use MQC, you'll have to use a MAP-CLASS frame-relay.

With your example i would do:

map-class frame-relay SHAPE
service-policy output SHAPE

interface Serial1/0
frame-relay interface-dlci <xxxx>
class SHAPE

Betreff: Adaptive shaping with MQC

Hi,
I am trying to configure frame-relay BECN adaptive shaping using MQC
(without using FRTS).

Will this configuration work?
<Config 1>
policy-map SHAPE
class class-default
shape average 64000
shape adaptive 32000

interface Serial1/0
service-policy output SHAPE

R1#sh policy-map int
Serial1/0

Service-policy output: SHAPE

Class-map: class-default (match-any)
6 packets, 82 bytes
5 minute offered rate 0 bps, drop rate 0 bps
Match: any
Traffic Shaping
Target/Average Byte Sustain Excess Interval
Increment
Rate Limit bits/int bits/int (ms) (bytes)
64000/64000 2000 8000 8000 125 1000

Adapt Queue Packets Bytes Packets Bytes Shaping
Active Depth Delayed Delayed Active
- 0 0 0 0 0 no

When I take a look at the result of "sh policy-map int" as above, "-" is
displayed under "Adapt Active". Shouldn't "BECN" be displayed here if
configured correctly?
If I configure as following, "BECN" is displayed under "Adapt Active".

<Config 2>
policy-map SHAPE
class class-default
shape average 64000
shape adaptive 32000

interface Serial1/0
frame-relay class MAP

map-class frame-relay MAP
service-policy output SHAPE

R1#sh policy-map int
Serial1/0: DLCI 102 -

Service-policy output: SHAPE

Class-map: class-default (match-any)
0 packets, 0 bytes
5 minute offered rate 0 bps, drop rate 0 bps
Match: any
Traffic Shaping
Target/Average Byte Sustain Excess Interval
Increment
Rate Limit bits/int bits/int (ms) (bytes)
64000/64000 2000 8000 8000 125 1000

Adapt Queue Packets Bytes Packets Bytes Shaping
Active Depth Delayed Delayed Active
BECN 0 0 0 0 0 no

So I think the 2nd config will work, but what about the 1st config?

Thanks in advance.
