Reserve Bandwidth / QoS
Hello,
I have a site that has a T1 - I need to reserve the bandwidt for all internet traffic to 90% of that T1, while allowing the voice traffic which is on a specific port to use all 100% of the bandwidth. Please advise on to the best way to achieve this.
Any assistance with achieving this would be greatly appreciated.
Hello Michael,
This will need to be done with QoS priority with Policing or shaping.
Please follow the next document:

That should do it for you.

Available bandwindth and 'max-reserved bandwidth'
Is the max-reserved bandwidth only important when working with Qos classes and the bandwidth statement? Is the default 75% available bandwidth only used then?
In other words if I have a 100MB link with a service policy applied for Voice, Call-Control and video. After that I notice the available bandwidth on thie 100MB link is 61280 kilobits/sec.
If I put in a 'max-reserved bandwidth 95' would I reclaim another 20MB of bandwidth for the class-default? Would leaving 5% on the 100MB link for routing and other stuff be acceptable?
Here is the config and show commands:

Max-reserved bandwidth confusion
Hi all,
Can someone please help me to understand bandwidth reservation for CBWFQ.
By default you cannot allocate more than 75% of the interface bandwidth to your classes. My question is what is the point? theoretically it is reserved for your routing protocols etc.etc. but in reality if the interface is saturated isn't that extra 25% used by whatever traffic anyway? it not like you guarantee a maximum of 75%, you guarantee a minimum of 75% so the additional 25% is still up for grabs, it's just that it's not reserved for any class in particular.
hope the question makes sense.
Thanks,
AndresHi Andres,
On low speed links, WFQ is the default. So in the case that you have a link with less than 768 kbps, it will be running WFQ. With WFQ, it's not so much 'up for grabs'. WFQ is based on packet size, DSCP values, and time in queue.
Generally, router control packets aren't very large, and by default they are usually in the DSCP 48-64 range, which is very high. So in this case, the control packets are very high priority.
As well, control packets are marked with a special tag on the backplane of most routers (platform specific) to give an even high level of precedence within the router.
When the max-reserved bandwidth is a very high value, it is more likely for the traffic to have a higher interference with these two methods (particularly the first).

Max-reserved-bandwidth 100% for the interface
According to CCO as following text, the remaining 25 percent of bandwidth is used for overhead, including Layer 2 overhead, control traffic, and best-effort traffic. I want to know why cisco choose 25 percent. why not 30% or 20%?
If I config the max-reserved-bandwidth 100% for the interface, does it will effect the routing protocol? also effect the network conectivity?
thanks for your answer
=======
Usage Guidelines for max-reserved-bandwidth
The sum of all bandwidth allocation on an interface should not exceed 75 percent of the available bandwidth on an interface. The remaining 25 percent of bandwidth is used for overhead, including Layer 2 overhead, control traffic, and best-effort traffic.
If you need to allocate more than 75 percent for RSVP, CBWFQ, LLQ, IP RTP Priority, Frame Relay IP RTP Priority, and Frame Relay PIPQ, you can use the max-reserved-bandwidth command. The percent argument specifies the maximum percentage of the total interface bandwidth that can be used.
If you do use the max-reserved-bandwidth command, make sure that not too much bandwidth is taken away from best-effort and control traffic.
The max-reserved-bandwidth command is intended for use on main interfaces only; it has no effect on virtual circuits (VCs) or ATM permanent virtual circuits (PVCs).Kevin,
this is the wrong group for this question.

"Insufficient Bandwidth" QoS workaround?
Does anybody have a workaround for the "Insufficient Bandwidth" problem that has plagued iChat 3 users. I have troublshot everthing I can think of, and the only thing I can come up with is my ISP says they are in the process of "bettering" their QoS service. Is there a way to make iChat 3 work like iChat 2 by turning QoS off?
HELP!!!Hi,
It may be how this commbo is set up
airport card/ netgear router/motorola cable modem
IF the Netgear is using DHCP to give out addresses then the modem needs to be set to pass through the Public IP address or be Static to the router. This will get around any Double DHCP problems.
The next thing to consider is if the modem is Static it will need the ports to be opened. In this case the Modem and the router should not be using Port Forwarding or NAT to open the ports as iChat does not like Double NAT situations.
Port Triggering or UPnP to open the ports will allow multiple computers to access the net using the same ports if required.

Lowering my bandwidth (Qos?) setup help needed
In order to better decide if a lower bandwidth from my provider will suffice I'm trying to find out if there's a way I can configure my router to limit bandwidth to a certain speed, so as to simulate what this lower speed will feel like.
Having read several threads on the subject it seems like the "QOS bandwidth management" feature is the way to go, which my RVS-4000 router has. However, even after reading Cisco's configuration guides and other Cisco pages on the subject I'm having trouble setting this up, finding it a bit complicated for a network novice to understand. Can someone please tell me how to set this up?
Enclosed is a screenshot of my router's QOS page.Yes, this seems to be true if you go to the "manual" set-up method. It failed for me too, several times, because of this. Finally, I even tried to set the TC to Create a network of the same specs of the network I wanted it to join. That failed, as expected, because it caused interference with the existing network on my old AirPort Extreme Base Station. My next try was to connect AirPort Utility to the TC (wirelessly from my MacBook) and retry using the easy set-up method. Lo and behold, it worked, and "Join Existing Network" now appears on its Manual Setup panel in AirPort Utility.
Looks like a little bug in AirPort Utility, having that pop-up menu sometimes missing that item.
So, long story short, my TC had this problem, and now it works.
I'd go through the setup from factory reset again to document it exactly, but the family is using it now, so the best I can do is describe it from memory. If the easy setup to Join Existing Network doesn't work for you, then re-do the setup to Create Network with the same specs as the one you want to join. Then when it comes up arguing with the other Base Station ("I am the master of this network." +"No, I am the master of this network!"+), go back to AirPort Utility and connect to the TC, going through the easy setup again, choosing Join instead. Then it might work. -
Upstream bandwidth QoS profile 5508 WLC
Hello,
Is it possible, through a QoS profile, to control how much bandwidth a user gets to use for upstream traffic? I can easily set limits for downstream traffic, via the per user bandwidth contracts, but it is not obvious to me on how to control upstream traffic.
Any and all info is appreciated!
Thanksupstream traffic needs to be defined at L3, via your QoS settings. As you've said, the profile on the WLC is downstream only.
HTH,
Steve

Hi all,
could someone tell me if it is possible to reserve a precise amount of bandwidth for a given vlan on the Aironet1240AG ? If yes, could someone tell me how ?
Thanks in advanceHi,
It seems that it is not possible to reserve a bandwidth for a specific VLAN. these APs are layer 2 devices with limited capabiltites. -
Linksys SRW248G4 Bandwidth QoS problem
Hi everyone,
so I bought the SRW248G4 switch because Linksys advertises ingress and egress traffic shaping. I setup everything and tested egress at 10000 kbps which worked fine. But when I setup ingress on any of the ports I get very bad rates that don't even correspond to the limit I set. For example I can set 10000 kbps or 20000 kbps, and I only get 12-20 KB/s transfer rates, which almost below 196 kbps. Does anyone know why this would not be working? Anyone else out there with a similar problem?
Thanks,

QoS bandwidth rate limit don't work
Hello
Buy a router RV120W, and one of the reasons is limit of bandwidth (QoS). I set up a profile of 1-256 kbps limit, and apply it to the only VLAN that is configured, but does not work and can navigate using the full bandwidth of the internet connection. My firmware version is 1.0.2.6
Screenshots attached
thanks
screenshots attachedStruggling with a similar issue:
the setup: internet adsl <--1mbs--> combined router/modem <--100mbs--> RV 120W
Internet speed is 1mbs. I want to priotize voip calls (via port) and deprioritize one machine (doing downloads). rest of the network should have something in between.
Firmware upgraded to 1.0.3.10
I created the profiles bindings, then in QoS settings, selected Priority, Wan total bandwidth 1mbs, and distributed my profiles onto low/med/high (10/31/61).
When what should be low is downloading, it gets the whole 1mbs and the other are dead slow.
Changed to rate limit, changed the parameters, etc... no more luck.
Can you please shed some light as how to configure this - in my case, the whole bw of wan is being used, and prioriization is not happening,

Hi,
I have a scenerio where i wish to configure a TE tunnel to run across a link which is only utilised as a backup link by the current MPLS network.
Am i right in assuming the RSVP bandwidth reservation carried out by the TE tunnel would not be seen by the normal MPLS traffic. IE, in the event of a failure the normal MPLS traffic would not see that perhaps 50% of the link is reserved by the TE tunnel and possibly starve the tunnel of the required bandwidth?
GarryYou are right in your assumption. MPLS TE tunnel will seamlessly integrated with the normal IP or MPLS traffic without causing any trouble.
Also you may want to use 'AutoBandwidth Allocator' for reserving bandwidth instead of allocating constant value manually.

i want to ask a question , could this be from IOS ???? -
WRR QoS unused traffic classes
We are planning QoS for the enterprise LAN and MPLS core. At present, there are 5 traffic classes identified and no VoIP traffic. We could allocate resources and bandwidth for 5 queues and deploy such configs. But I guess it's worth defining all 8 classes and allocate queue limits and bandwidth to them. Later it will be easier to mark the new traffic and classify it into the unused queues without modifying the wrr config.
67xx 1p7q8t line card
Q3 and Q8(PQ) will not be used. 5+15% is allocated to them.
priority-queue queue-limit 15
wrr-queue queue-limit 30 15 5 10 15 5 5
wrr-queue bandwidth percent 30 15 5 10 15 5 5
I'm not sure if the allocated bandwidth and queue limit for the unused queues will affect the existing traffic and limit the aggregated traffic quantity. Will the 5 classes be able to fill the bandwidth until there is no congestion? What happens in case of congestion? Can the traffic excess 80% or not? (For simplicity, 100% is regarded as a fraction of link capacity defined by max-reserved-bandwidth)Disclaimer

Generally, unless you're shaping or policing, bandwidth sharing commands provide a minimum bandwidth guarantee, and unused bandwidth can be used by other queues. Also when working with more than one queue, relative ratios are usually preserved. So, for instance, if q1 was configured for 25%, q2 for 25% and q3 for 50%, if q2 had no traffic, and q1 and q3 wanted all they could have, they would split the bandwidth 1:2 or 1/3 to 2/3. -
Hi, guys!, using MPLS VPN, using a MGX 8830 (RPM) providing QoS to costumer; costumer is complaining about voice cuts when passing data...we`re using Multilink (ppp) interfaces fot the costumer, the conf:

In the CPE is seems OK the conf, in facto we applied an ACL on the CPE receiver interface (Multilink), and it seems is receiving good marking, i`m just not very sure about what (0) means...a port??:

i can`t find any conf issue..can anyone give any ideas for troubleshooting?, thanks!!Hi, thanks for the answer, yes , the policy is supposed to be working:

Talking about the signaling, i`m using an ACL :
Extended IP access list Signaling
10 permit tcp any eq 1720 any (15615 matches)
20 permit tcp any any eq 1720 (344 matches)
In order to match these ports, the BW is a 128 kbps; and this problem only happens on an RPM with PPP, not with a normal router with CBWFQ with FR; everything seems to be OK, but the costumer`s config also seems OK..on an ACL that i put on the costumer`s Multilink i`m seeing that the packets are arriving matched; but the problem is still alive...any suggestions for test????, i`ll appreciate it...
