I want to take 100Mb incoming from a service provider and police it off into several VRFs for customers.One of these VRFs will be 30M.I further need to traffic shape this (30Mb) out to 40 x 0.75Mbps (burstable to 30M) customers.
I am using an ASR1001.
We are looking to implement traffic shaping/policing primarily for P2P traffic. As natively the ASA5550 is only capable of p2p inspection if the traffic is tunneled via port 80 is the AIP-SSM the way forward? We have 2 5550s in active/active failover config. As a side note we are also looking to implement an IDS/IPS system so could this module cover all?Is this module going to provide the desired outcome or is there another module/device out there better suited for this? I would prefer to use the ASA5550s as opposed to implementing another product if only that we can make use of the investment we already made on these devices.
View 1 Replies View RelatedI am suggesting an ASR1001 as a head end router for a small hub spoke WAN consisting of 4 branch sites connecting to the head via LES. 3 are 100mb, one is 30 mb. I will be connecting the LES circuits to a swithc and then trunking to the router. I would like to apply outbound shaping to these 4 subinterfaces on the router, and just want to check this is supported?
View 1 Replies View RelatedI have lots of PPPoE users that get Virtual Access interfaces created upon login based on a virtual template. I need to traffic shape them. I know how to get it to work on an individual basis, because the policing within a service policy works fine. As soon as i change it to shaping it leaves things wide open.I really dont care how it gets done, I just need to be able to specify a speed to be traffic shaped and apply that to a virtual template. I need to limit speeds on the download and upload, i understand that the upload i will use the policing, but the download i need it to smooth out the flow and be traffic shaped, not policed.
Here is my Policies and classes:

The results i am getting is unrestrcited throughput, i am seeing about 40mb of throughput when the target is to limit to 1.65MB. As you can see from the output the PARENT class is seeing 279116 packets, but the shaper only saw 59. In all the examples i see on the internet these two numbers should be the same. Why is the shaper not acting on all the traffic crossing that class/policy?

We are looking to implement a bandwidth policy for our Internet link. What i would like to know is if we use a policing policy, will the exceeded dropped packets be resubmitted from the source? Will the dropped packets be resubmitted? Are there any differences besides this when using either policing or shaping policies? Is one better than the other?

I am configuring a 3560 to provide internet access for our customers and I need to make sure they don't use more bandwidth than they have contracted for.I see that the 3560 supports the rate-limit command, but was told that I should use traffic shaping and policing along with access lists to manage the bandwidth.Is there a reason that I should avoid using the rate-limit command - it looks much simpler.
View 10 Replies View RelatedI am trying to come up with the best way to traffic shape traffic with 3750 Me switches. the traffic will be coming from a 6504 Sup-7203b downstream and going out the wan. Core---L3---->6504--intvlan80--trunkport to--->3750Me---g/1/1/1-trunkport to---MetroE network--->int f0/0.80--branch router. The idea is to use the 3750 to traffic shape the traffic going towards the wan/branch to 500 to match the contracted rate and then to use qos on shaped rate. I tried to apply it to g1/1/1 using port based policies but it did not shape the traffic. I changed everything to IP interfaces and it worked. I need to break up the metroe into different vlans so I can bring branch offices in on different vlans.c
View 3 Replies View RelatedI have two servers on one subnet that each need to replicate to a single server on another subnet. They also need to replicate to each other. This replication is unidirectional so I will refer to the 2 server subnet as the source subnet and the single server subnet as the destination subnet. In order to keep this replication running without killing the MPLS links on either end, we are trying to use a policy-map that limits bandwidth from the source subnet.The Problem:We have created a policy that polices traffic during specific times of day and limits the bandwidth as prescribed, however, bandwidth is also being limited between the 2 servers on the source subnet which is not needed or desired.Class 512K set dscp ef police 1024000 bps 1024000 byte conform-action transmit exceed-action dropClass Map match-any 512K (id 4) Match access-group name DAGExtended IP access list DAG 10 permit ip host 10.20.0.3 host 10.20.0.10 time-range DAG-REP (active) (22793 matches) 20 permit ip host 10.20.0.4 host 10.20.0.10 time-range DAG-REP (active) (14156 matches)The service policy is applied on the input side of the 2 interfaces on which our devices are connected.As you can see, the access list identifies the interesting traffic as traffic from two specific hosts to one specific host. The problem we are having is that bandwidth is also being throttled between the two source hosts even though it is not defined to do so.What can I do to limit traffic from the two source devices to the single destination device without limiting bandwidth between the two source devices?

View 5 Replies View RelatedI am a traffic shaping newcomer and need some guidance as how to BEGIN to approach a problem with traffic. We have been rolling out Windows 7 at sites and the additional traffic it causes on installation is considerable as it has to request information from our central site to populate My Documents and Outlook mailboxes.This has caused some problems on sites as there traffic rates increase to the point that QoS is not sufficient to protect voice traffic and delays and one-way audio are being experienced.One question is this - is GTS a solution or is CBWFQ within GTS the solution or is something else preferable? The sites involved are data/voice with a variety of routers.Second question is this - if we have a remote site with a 3725 router as the WAN aggregator with one 4506/Sup IV and one Cat 3550-24-PWR the shaping should be best placed on the 3725, correct? Also, are there issues with shaping incoming/outgoing traffic as I seem to have read?FYI, the 3725 router has 12.4(8d) with IP VOICE/NO CRYPTO IOS version. The 4506 has 12.1(23)E4 with basic L3 feature set.
View 1 Replies View RelatedWhat's the good, inexpensive way to add traffic shaping to a small network? Let's say there are about 20 users on a T1 circuit. Existing router is an Adtran 3430 (from the telco so we can't touch it). Everything works fine except when they get really heavy with uploads/downloads when document scanning, and the telnet sessions to the mainframe app start getting dropped. Major PITA. Basically need to make telnet traffic a priority.Now, I could drop a pfSense box in there using an old workstation, but I'd like something I can stick in a rack, or is at least really small and hopefully under $200 or so.
View 7 Replies View RelatedI have a 3825 with a 1Gb fiber card at one of my sites. Our ISP and MPLS provider hand off a single gigabit fiber to us that contains 2 50MB EVC's.I need to apply QoS to one of the EVC's and shape them both to 50Mb to avoid upstream rate mismatch bottlenecks. Both of the EVC's generally only push 10Mb during business hours.When I run UDP stream tests (various rates from 500k-6m that are marked as AF41) to one of my other sites I am consistently getting about 2% packet loss, despite the fact the circuit isn't even close to 50% saturation. When I remove Shaping and QoS all together, the issue nearly clears itself up, except during peak hours and I get small bursts of packet loss, which is still unacceptable.When the pipe is at near zero utilization (after hours) there also is no packet loss with or with out the shaping/qos applied.
View 1 Replies View RelatedThere is a remote server that downloads info from a server here at HQ. When the dowloads start the rxload on the S0/0/0 interface jumps to 98 percent or so; rxload 250/255.

We are a new medical school located in PA. Just have just completed a new building and are now working on getting our network finished. Here is the situation we have a 50MB Internet Connection that comes into our network that then hits the ISPs Cisco 3750 which sends it to two of our Cisco 3750s for redundancy. From the 3750 goes into our Cisco 6509 with a FWSM module, then out from there to our distribution switches which are all Cisco 2960s.
What we would like to do is to control how much WAN connectivity each of our VRFs get. Right now we have a Faculty, Student, and Research VRF formed, and are trying to figure out the best spot where we can say Faculty gets 30MB of Bandwidth, Students gets 10, and Research gets 10. If possible would like burst capabilities.

View 4 Replies View RelatedWe have built some policers to apply to vlan SVIs on our 7613 so that we can rate limit input and output traffic. We followed the Cisco formula and got this.
policy-map vlan-shape-3meg
class class-default
police cir 3000000 bc 562500 be 1125000 conform-action transmit exceed-action drop violate-action drop
There have been some complaints about this not actually meeting the limit. When I do a show policy-map interface xxx I get this. Based on that it looks like the Be value is being change to match the Bc value.
On a separate note, I noticed that every policer we built with the cisco formula actually ends up with a Tc greater than the max Tc of .125 seconds. It seems odd that a recommended formula would end up creating values outside the maximum allowed limits by the software.
I'm not a QoS expert so if any of this seems like basic stuff it's just because I'm a little slow on QoS.

I noticed in RME inventory, my ASR1001 hardware is not recognized. I checked my Ciscoworks and it only knows ASR1002, 1004, and 1006 routers.
I checked the supported device table for LMS 3.2 and did not find ASR1001. Is there a separate device package I can download. This is not a deal breaker, but it's unnerving to see the question mark icon next to the name of my router in the Cisco works GUI.
I know most QoS capabilities aren't available in multiple context mode, but I need to do some really simple policing on one of my contexts. I just want to apply a hard 20Mbps cap on an interface. I've seen a few places that suggest that basic policing is possible in multiple context mode, but apparently not by the normal commands.
