ME 3400 minimum traffic shape rate
Hi
I just implement traffic shape for output traffic on interface FastEthernet:
policy-map megann-10M-out
class class-default
shape average 10485500
int fa0/5
switch-2(config-if)#service-policy output megann-10M-out
QoS: Configuration failed. The configured rate is not achievable in hw within 1% of configuration.
Closest value(s) are: 11111120 bps, 5882368 bps
What is "1% of configuration"? It's not an 1% of interface rate?
Hello,
this is somewhat odd and looks like only predefined rates are achievable with shaping. The command reference does not mention this at all
http://www.cisco.com/en/US/products/ps6580/products_command_reference_chapter09186a008051341a.html#wp5979557
but gives an example with 10000000. Maybe you can try this value?
I understand the message like this: you are not within 1% of the rate 11111120 bps with your configured value. Have you tried to configure shaping to this rate?
Hope this helps! Please rate all posts.

Traffic Shape in ethernet - C3750Metro
I have a scenario where, one hub site which is connected to metro ether MAN at 1Gbps and spoke sites are connected to metro ether MAN at 100Mbps, in these remote sites variable bandwidths are agreed with service provider: 20Mbps, 40Mbps, etc.
I only want to configure "traffic shape" in my Catalysts because if I don't, these Catalyst use max. speed to transmit (100Mbps when 20Mbps is only permitted) and the network drops my excess traffic.
I don't want to configure anymore (different QoS for differents services, etc.)
Which is the best, and more elegant, way to do it?
Thanks.access-list 1 permit any
class-map match_metro

policy-map match_metro

This is a just a sample config to achieve what you want, you should check the following link for a more thorough explanation.
Traffic shaping allows you to shape output traffic (egress traffic) on a per-physical port basis. Ucode monitors output traffic to verify that it conforms to the rate configured on the switch router. When excess traffic comes into the switch, the output side of the processor interface applies back pressure and queues the excess traffic in the switch fabric.

Can I traffic shape to 200Mbps on ASA5510 inculde security plus license ?
Hello Expert,
I have ASA5510. It's include security plus license.
I want to traffic shape to 200Mbps. But , I checked a CCO.
CCO said that a shaping limit is 154400000.
"Enables traffic shaping, where the average rate argument sets
the average rate of traffic in bits per second over a given fixed
time period, between 64000 and 154400000. "
It's mean shaping limit 154400000 ?
Can I shape to 200Mbps ?
regards,
takuro.Takuro,
Yes what you found is correct.
http://www.cisco.com/en/US/docs/security/asa/asa84/command/reference/s1.html#wp1451099
you can do upto 154.40 Mbps

Number of traffic shaper(queues) supported
All,
Just want to know what is the max. number of traffic shaper (queues) supported:
1. ingress shaper / ports
2. egress shaper / ports
for the Enhanced 4-port Gigabit Ethernet OSM, datasheet say up to 8000 traffic queues but does not indicate whether it is for shaping or rate limiting. and also ingress or egress.
thanks,

Frame-relay traffic shapping question
Dear all.
i have a question related to the frame-relay traffic shapping question.cir is the commited rate. bc is the traffic which is sent during every ime interval. be is the excess burst.
example. i have line 128kbps to service provider. 64 is my cir so in the map class frame-relay cir 64000 and bc is 8000 which means 8000 bits will go every interval which is by default 125ms.now about be. excess burst will go only in the first interval or every interval ? if i say frame be 32000. will 4000 additional bits go in every interval ?
please advice .Here's my summary of shaping operation:
* The token bucket used for shaping has a size of Bc+Be (if Be is zero, this equals Bc)
* The token bucket starts off full i.e. with a capacity of Bc+Be
* At the start of every Tc interval, Bc worth of tokens are added to the bucket. If the number of added tokens would result in the capacity of the bucket exceeding Bc+Be, these excess tokens are discarded.
* After the tokens are added to the bucket, the shaper checks if there are any packets that are waiting to be transmitted. If there are, an equivalent number of bytes of packets as the token bucket contents are transmitted. If there are more packets than tokens, these packets will have to wait until the next Tc.
* The capacity of the token bucket will approach Bc+Be only of the traffic has been quite for a little while.
* The maximum amount of traffic that can be sent in any interval is Bc+Be, since that is the size of the token bucket. If the bucket has filled up to Bc+Be, this implies that the connection has been quiet for a little while so that we can allow it a little burst.
* The long-term average of traffic will never exceed CIR, since the token bucket is filled at a CIR rate.
Now, applying this to your example, the maximum size of the token bucket will be Bc + Be = 40000 bits. The bucket will fill up to this level only if there are no packets in the queue for a little while, allowing the bucket to fill up. Then, say that that a 1500 byte (12000 bits) packet comes along. It will be transmitted and the token bucket size reduced to 28000 bits. If there are more packets, they will be transmitted as long as the token bucket has sufficient packets. If there are no more packets, the token bucket will be filled with another 8000 bits (Bc) at the next measurement interval, giving a total of 36000 bits. Whether or not all the Be + Bc bits will be used up in the first interval depends on how many packets are waiting in the queue. If there are sufficient packets, they can all get used up. If not, they get carried forward to the next interval.
Pls do remember to rate posts.

Hi, I have:
Cisco 2800 with HWIC 4ESW module (4 port FE switch), IOS 13.3(8)T8, Feature Set IP. 10 VLANs are defined, 2 assigned directly to 2 4ESW ports, 2 port are trunk.
How to configure traffic shapping on VLANs? I need shape 10Mbits from one Giga port to 10x 1Mbits for every VLAN.
When I use this configuration, Giga interface is shapping, but VLAN running without shape.
It is possible?

Traffic Shapping on ESW500 switches
Hello all,
I am faily new on the traffic shapping / bandwith control department, and have been asked by a client to be able to do some traffic shapping in their main office.
I've read some documents on the ESW500 switches and wanted to make sure that my understanding of the technology and product is right.
My client wants to prioritize bandwith per port depending on the bandwith usage needed. Some users needs a lot of bandwith for critical applications while others
uses a lot of bandwith for not so critical applications...
From what I've read, I should be able to replace his switch with an ESW500 switch and do some traffic shaping. He has a pretty basic setup with about 30 computers connected to a switch which is connected to a router. As mentionned, if I replace the switch with an ESW500 switch, will I be able to limit per port bandwith usage both inbound and outbound?
Is there also some kind of monitoring tool I could use to see how much bandwith used per port (not required but would be a nice to have feature).
Thanks!
MattHello Matt, I hope this finds you doing well.
The amount of bandwidth you need is directly related to the performance you require. What performance do you require?
Here is one example (for voice)
150 msec one way delay
Less than 20 msec jitter
Less than 1% packet loss
With requirements for this, you will have to have the right amount of bandwidth per call and queueing control, or else the call not sound right or may even be dropped.
Another example might be for Microsoft's RDP:
Some web posts mention that 30kps is needed, and some say 100kbps is acceptable.
So this is a bandwidth target, lets say 100kbps per user for this example. If you have 10 concurrent sessions, then this is a max amount of bandwidth needed around 1Mbps. With statistical multiplexing, you should not need this much, since not all clients will burst or use the max amount of bandwidth at the same time. You can probably get by with less ...
The point I am making with this, is once you know how much bandwidth you need, then you can begin to engineer your network so that critical applications are able to function and user productivity is kept high. User productivity is so very key, and it is very good to see you looking into this as you are Matt. Good stuff Matt.
Do the application vendors have suggestions for you for how much bandwidth their apps require?
If the application vendors do not know how much is needed, then using Cisco devices, you can define the performance you require and the Cisco device will respond with the required bandwith per queue. This is called 'corvil bandwidth' or bandwidth estimation. Using this bandwidth amount, you can configure your QoS settings on all your devices.
Here is a link and I would suggest to poke around some:
http://www.cisco.com/en/US/docs/ios/qos/configuration/guide/qos_bndwidth_est.html
Application performance is an end to end perspective and consideration. You need intelligence at the edge, core, and remote edge.
You can also look at the interface statistics to understand what an end user is using when accessing an application. This can be an inaccurate method, but it might help you in your understanding.
With all of this said, most folks do not notice a lot of congestion on the LAN or from one LAN port to another LAN port. Usually problems occur at bottlenecks and uplinks. Where are the bottlenecks in your network?
Once you know where these are, then you can apply a QoS policy to protect the important traffic and ensure application performance meets your needs. What are your needs? See the above for some thoughts.
Does this make sense?
The ESW is a great switch, and QoS can be easily configured to meet your needs. I think a harder question is ... what are your needs?
Here is a link for the ESW switch. Click on resources to find the docs provided with this switch:

ACL matching for traffic-shape...bug?
I am using a C6503-E.
My goal: create a traffic-shape rule on an interface (in this case g3/7) which will restrict all traffic between two internal addresses (10.0.0.7 and 10.1.0.6) on port 2152 to 128Kbps, and allow all other traffic to pass unfettered.
I am aware that the 6500 series ACLs are hardware based, and that some counters will not show up in the normal 'show access-list' display.
I have created an access list which increments when tagged with a 'log' modifier, so i know that it is hit when placed on the interface, but when referenced in a traffic-shape command, the traffic is not shaped. Unfortunately, the traffic-shape command will not allow the use of the 'log' modifier, so I'm stuck with my imperfect 'the ACL works in this scenario, but not this scenario' method.
Extended IP access list 195
10 permit udp host 10.0.0.7 eq 2152 host 10.1.0.6 eq 2152 log (2822 matches)
interface GigabitEthernet3/7
ip address 10.2.0.1 255.255.255.252
no ip redirects
traffic-shape group 195 128000 7936 7936 1000
Acc. Queue Packets Bytes Packets Bytes Shaping
I/F List Depth Delayed Delayed Active
Gi3/7 195 0 0 0 0 0 no
Any ideas on why an ACL wouldn't get hit in a traffic-shape rule, when it clearly gets hit when used strictly for access?
Thanks!Please post your entire QoS config.
Your access list is just doing matching; it is not doing any setting for your DSCP values.
Also, I think the Polycom's are IP precedence aware and set their outgoing VC packets to 5.
Also, matching protocol 46 (RSVP) isn't really going to help - RSVP does not transport application data. It is only used for requesting resources from the network.
Also, a Cisco search for QoS and Polycom returns this url: http://www.cisco.com/en/US/tech/tk652/tk701/technologies_tech_note09186a0080111c1b.shtml

Traffic Shaping on a 2600 router (IOS ver 12.2.31)
I have configured traffic shaping on a Fastethernet subinterface as follows;
f0/0.1
traffic-shape rate 256000 7936 7936 1000
After reviewing the management graphs it looks as though the Traffic Shaping is not working as the graph shows a utilization of 800%. Is there a known reason for this and is there a way I can check on the router. I have ran the show commands but nothing is obvious as to the reason for this. The router is a replacement for a 1721. The same config has been applied. This started happening when the routers were changed.This is a very vague question, but you may need to add a bandwidth statement to your interface for your application to correctly interpret the utilization.

OSPF Equal Cost (multiple links) but unbalanced traffic
Hi!
I would like to ask about OSPF.
We are using 4 links running OSPF point to point with equal cost to load balance MPLS L2 traffic between our two routers.
And from what we are experiencing right now is that it didnt balance the load the way it should have.
The first link always catches up the bulk of the traffic, while the remaining 3 links load balances, I would like to inquire on steps to mitigate the issue.
Appreciate if I could receive some help to solve the issue
Thank you very much in advance!
Best Regards,

I see majority of the traffic using the link F0/0/0 and only 30% traffic using the second link F0/0/1.
I used per-packet load-sharing on these interfaces which caused throughput problems, so i removed that from the interface. Should i add some CEF commands or should try per-destination load sharing to see equal traffic on both links ? -

Thanks very much,
NhuongPhamWhen you're able, schedule some downtime for this circuit, and have your provide do some loopback testing on an off-hours time. Simply open a trouble ticket with them, indicating that you're taking CRC errors at the customer-premisis-equipment. 16 input hours per day doesn't seem like alot, but it's still worth checking out, especially since your WAN provider should do this for free.

I have over 250 sites in a hub-and-spoke desing, each remote site has a frame-relay and an IPSec tunnel to the office, we are running Eigrp but ever since we deployed DMVPN we've been getting many SIA messages...is this a normal behavior for a DMVPN design? should I just decrease how often EIGRP queries are sent or increase EIGRP timers, or should I just leave it alone...has anyone seen DMVPN in over 200 sites working flawlessly using eigrp? just curious...
GTS = Generic Traffic Shaping.
We just use the easier to use, traffic-shape rate command, but the likely cisco answer would be to create policy-map/class-maps for the tunnel interfaces.
Our Tunnel interfaces have the following additional commands. cut-edited-paste.
Site with a T1
interface Tunnel111
description VPN sitea to siteb
bandwidth 1536
ip unnumbered Loopback0
ip access-group whattoblockin in
ip access-group whattoblockout out
ip mtu 1600
ip hello-interval eigrp 111 2
ip hold-time eigrp 111 8
ip pim sparse-mode
ip route-cache flow
ip tcp adjust-mss 1280
load-interval 30
delay 1001
traffic-shape rate 1536000 8192 8192 2048
cdp enable
tunnel source a.a.a.a
tunnel destination b.b.b.b
end
The traffic-shape command is just there to keep the outside interface from being over run and dropping packets after encryption. This isn't "QOS" by Cisco's book, but when we implemented this, Cisco didn't have a pre-qualify that worked properly with DMVPN.
If we start having problems with a site having heavy utilization, we'll change the traffic-shape statement to smooth out the traffic and control the heavy users. (refer to effects of WFQ).
Do a search for WFQ and GTS on Cisco.com
(oh, and if anyone tells you that the ip mtu command is a bad idea, tell 'em to stick it in their ear...)
