Cisco Switching/Routing :: WS-4507R / Policy For Traffic Shaping?

Feb 18, 2012

I am trying to do policy on the interfaces of my switch WS-4507R, below the configuration I used to shap the traffic to 1 Mbps. However, when I tested it the traffic excceded the 1 Mbps.
class-map match-all 1MB
  match access-group name 1MB
policy-map 1MB
  class 1MB


how I can restrict my bandwidth on the interface on 1 Mbps.

Cisco Firewall :: Can The ASA 5520 Do Traffic Shaping Or Policy Map Just Like In A Normal Router

Feb 13, 2011

ASA 5520 can handle 2 ISP? not to load balance or not standby/active but to use the 2 ISP at the same time and separately. for example, ISP_A who has 10m will be dedicated to the customer A/VLAN A, then ISP_B who has 4m will be for the rest of the customer's traffic. Can the ASA 5520 do traffic shaping or policy map just like in a normal router?

Cisco Switching/Routing :: How To Setup Traffic Shaping On 4500X Outbound Port To WAN Routers

Mar 26, 2013

We have some ASR WAN routers which have a dedicated 400M interface to a remote site.
Servers on our Local network source the data through some firewalls via 10G interfaces, which connects to 4500X WAN switches then to the Routers on 1G links.
The sources are rate limiting the traffic but the routers are periodically dropping packets which I think is mostly due to burstiness in the traffic between as it traverses through from 10G links to 1G then to 400M. 
How to setup traffic shaping on the 4500X outbound port to our WAN routers.I'd like to see if we could buffer and smoothe out the traffic as it exits the 4500X WAN switch 1G port to the WAN Routers.

Cisco Switching/Routing :: Switch 3750 / Policy Inbound Traffic Per IP?

Mar 2, 2012

We are using Cisco 3750 switches in our environment as distribution switches.We currently use to police inbound traffic, but we need to find a solution to limit inbound traffic per IP.Something like this “Inbound traffic for each IP can be maximum 1 Mbps” This can be done having, one ACL and one class-map for each IP, but in my situation is not a practical solution, because we have more than 500 IP’s on that site.
Is any way to accomplish this without writing 500 ACLs and 500 class-map?

Cisco Firewall :: ASA5550 - Implement Traffic Shaping / Policing Primarily For P2P Traffic?

Mar 10, 2011

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.

Cisco WAN :: 3750 ME Traffic Shaping Downstream Traffic

Aug 4, 2011

I 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

Cisco WAN :: Traffic Shaping On 3725 With T1s?

Mar 15, 2011

I 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.

3430 Cheapest Way To Add Traffic Shaping?

Jun 19, 2013

What'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.

Cisco WAN :: 3825 Traffic Shaping And QoS On Multiple EVC

Feb 6, 2011

I 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.

Cisco Infrastructure :: 185 / Traffic-shaping On The LAN Interface?

May 5, 2011

There 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. I needed to limit the bandwidth utilization between the servers, so I added the below line to the LAN interface on the remote router.By adding the command, it reduced the download utilization -which is what I wanted.
access-list 185 permit ip host any
int f0/0
traffic-shape group 185 10000 8000 8000 1000
Question:How would applying this to the LAN interface cause the download utilization (Coming from s0/0/0) to decrease?

Cisco Switching/Routing :: 2921 - Queue-limit With Shaping

I have a 2921 where I am shaping some traffic based on sub net on my lan.  I have applied the shaping policy to the lan interface in the outgoing direction.
Topology is as follows:  
Policy map: 
Policy Map shape-lan
I am seeing a lot of no-buffer drops on the policy and I am wondering what the best solution is to solve this: 
Class-map: tc-class (match-any)
   8730680 packets, 10803689863 bytes
   5 minute offered rate 4453000 bps, drop rate 0 bps
Should I just be increasing the queue-limit or should I be changing something else?

I need also to specify to the router the total internet bandwitdh available (example: 20mbps symetrical).
This configuration will work ? Should I worry about any performance issue if I start to have a lot of customers ?

Cisco WAN :: 3750 / 6509 - Traffic Shaping VRFs WAN Bandwidth?

Jul 14, 2011

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.

Cisco WAN :: C7200-IK9SU2-M / QoS Traffic Shaping Not Working (but Policing Does Work)

Feb 8, 2011

I 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:

policy-map CHILD class class-default  bandwidth 1650policy-map PARENT class class-default  shape average 1650000  service-policy CHILD****
Here is my Virtual Template:
interface Virtual-Template8 description pppoe-auth-FTTH ip unnumbered FastEthernet0/0 ip access-group subs-in-FTTH in ip mtu 1493 timeout absolute 6120 0 peer default ip address pool FTTH-POOL ppp authentication pap pppoe-auth ppp authorization pppoe-auth ppp timeout idle 84600 service-policy output PARENT

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?
