Cisco Switching/Routing :: 3560 - Limit Bandwidth For Specific User On Switch Or Router?
Jan 24, 2013
configuring a switch or a router to limit the bandwidth for a specific user/IP when need it. Most of my remote offices are configured like this:
Users ------ 3560 switch ------- 2801 router -------- T1 to NOC -------- 7204 router with channelized DS3
I use Netflow Analyzer for high bandwidth usage alerts and can see the user's IP right away when someone is clogging our T1s. My goal is to be able to temporarily limit the bandwidth of the user taking over the T1. Whatever is best switch config or on the router.
I have a cisco 2821 router where as a cisco 2960 switch with connect on router as a trunk & one user vlan . this is my WAN router all traffic are internal . i have 2MB data connectivity on my WAN side. i have to Give a specific Bandwith on my SAP traffice . like when SAP traffice will come they all time get around 50 % bandwidth of my channel. If SAP resuest are not comming then other traffice will get full bandwith .
I have the requirement to assign an asymmetric bandwith limit to each port on a switch (example: 4Mbps downlink, 1Mbps uplink). I've been searching and found the option to apply policers or srr-queue mechanism to achive this, however this only applies for one direction only as far as I know. Catalyst 2960 familiy is preferred, however if this is not possible, will possibly jump to the 3560X family.
I use WS-C3560G-24TS and try both ios 12.2.50.SE1 and 12.2.46.SE but problem the same. The config as following, interface GigabitEthernet0/1 no switchport ip address 1.1.1.2 255.255.255.0 [code].....
but I find the int g0/1 output traffic only can achieve about 500kbps then I try config below,
interface GigabitEthernet0/1 no switchport [code]....
I find int g0/1 output traffic only can achieve about 5Mbps,but if I change "srr-queue bandwidth limit xx" command xx to 20-90,the int g0/1 can achieve normal traffic bps, for example,
interface GigabitEthernet0/1 no switchport [code]...
the int g0/1 output can achieve 2Mbps that is correct,just only when limit set to 10%,the traffic only can achieve half of limit bandwidth.
I want to configure switch port bandwidth limit for my Catalyst 2960-48, is there any hardware / ios limitation? can I configure it at all 48 switch ports?
I want to limit the bandwidth of my Catalyst 3750 series switch, I read the cisco documentation and I applied the commands but I didn't get the wanted results.
For the outbound traffic it's ok, but for the inbound traffic I used policing but I get an unstable traffic. I used, an access list and a class-map to classify the traffic and then a policy-map.(I followed the steps mentioned in this site: [URL]
How do I limit broadcast/mulitcast traffic on a switchport to e.g. 5000 pps ? I don't want the port to shut down, just block or drop broadcast traffic that exceeds 5000 pps.
I have a cisco 2950 switch, connected with 4Mbps of internet and number of users will access the internet. There is no restraction on bandwidth limit for users, if any body use high download the remaining users are facing the slow browsing problems.
So, if i can put a bandwidth limitation for every users the problem will be solved. how to restract the bandwidth on user bases.
I have a task of setting up bandwidth limit on the 2811 router Fastethernet interfaces.The scenario is:We have a 4MB Internet connection and would like to allocate bandwidth usage to users.
Fastethernet 0/0 needs to be set with 256KB output and 2048 input. This is going to be connected to a wireless router. Fastethernet 0/1 needs to be configured with 2048 output.I could also use SDM if that's easier than using CLI.
We will shortly be installing a Cisco 3825 router, to be connected to the BTNet service, over fibre.We will be binding many public IP addresses to the router.
Is there a way of defining a specific bandwidth limit per IP address, or range?
The rest of us use wifi for our internet services but this isn't good enough for are newest member so they have now connected a cable directly into the modem, so now whenever he is online ALL wifi suffers dramatically! What can i do to limit his bandwidth and allow the wifi to gain more access is there a way to limit via his MAC address or IP address?
I have an ASA which is managing internet access from mutiple VLANs configured on a 3560 switch. I want to be able to limit the 100MB internet connection on the ASA on a per subnet (VLAN) basis for the multiple subnets configured on the switch..
so for example
VLAN10 - 10.0.10.0 - limit to 5MB VLAN20 - 10.0.20.0 - limit to 10MB VLAN30 - 10.0.30.0 - limit to 3MB
Need to limit the amount of bandwidth a specific VLAN can use on a 802.1q trunk port. Situation is that we have a pair of Catalyst 4506 switches which have 802.1q trunk ports into a Checkpoint Firewall, this in turn is connected to a managed WAN router (to which I can't apply a QoS policy).If the 4506 was routing the traffic it would be easy to setup a class-map to match the IP traffic and then QoS the traffic, but the VLAN in question is trunked directly into the firewall (no L3/IP presence on the 4506 next hop for all clients on this VLAN is the firewall).What I need to do is restrict any traffic from this specific VLAN to 10Mbps on the uplink to the Checkpoint Firewall so it cannot impact the onward WAN.
How to rate limit a 3560 inbound and outbound using different QoS methods. I've read about vlan class maps/policy maps, using the rate limit command on the physical interface, using the srr-queue bandwidth command(it's a gig switch so not sure that would work) and marking all packets and then applying QoS. I'm just learning QoS so trying to figure all of this out and find the best way to do things.
Also, I was told to do this because it's not advisable to have a connection to your ISP that is not 10mb or 100mb on a switch, since they are not divisible by 10 and it can cause issues?
I am using Cisco 3560 as distrubution switch and want to limit port 445 traffic on 1 MB and applied rate limit statment on Gi0/1 port but switch unable to limit said traffic.rate-limit output access-group 120 1024000 128000 128000 conform-action transmit exceed-action drop.
We run a workers camp here and we currently have around 2500-3000 people using our 100MB internet pipe. We are upgrading the pipe to 200MB soon but I still would like to limit how much bandwidth everyone is using.
We allow streaming media such as Netflix, youtube, apple TV and of course .So it gets full pretty fast. We have QOS implemented although I wasn't here when it was done so I don't know a lot about it. I would like to limit IPs to a certain amount of bandwidth. [code]
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.
I have an environment of 3 X 3560G of which I have 1st switch-CORE(f0/10) connecting to the VPN router(CE) interface-f0/0. Remaining 2 Cisco 3560's(Access) are connected to Gi0/1 and Gi0/2 on the 1st switch-CORE via gi0/1 . On all three switches I have created multiple VLANs and assigned ports to these VLAN. The switch to switch connection is trunk allowing all VLANs created on all these 3 switches. Now the issue is how I am going to have all these VLANs routed through single interface on the routeri-e f0/0, as all these subnets will communicating to remote site over VPN. What should be default gateway on the 2 Access switches and the CORE switch, also what static route should be on router to reach all subnets(VLANs) created on these 3 switches.
I have read inter-VLAN routing i-e creating sub interfaces on router but dont want to proceed with that and looking for any other way to have my VLANs talk on all three switches and then are accessible to remote site ove VPN?
I have a cisco 3560 24PS and its connected to two ADSL broard band routers.one is a personal broadband line using a Billion ADSL broadband router, and the other is a business broardband line using BT's 2wire broadband line.on the Billion routers i have various things attached like a NAS and a printers, both wired connections. then i have laptops and phones that connect over wifi, so its configured to act as a DHCP server
the only thing conncted to my 2wire router is my company's laptop (wired or wifi depending on where i'm working from), so again i have it working as a dhcp server.The switch is configured with multiple vlans, with dhcp scopes assigned for each vlan.I have a static route pointing all traffic to my Billion ADSL for internet connectivity.
The problem i'm having is that when i turn on the cisco switch, all wifi conected devices loose their conection. only 2 things get it working again, a reboot of the router, or disabling then enabling the DHCP service on the router.upon further analysis i was able to find out that the devices were not able to pick up an address from the router. again i looked deeper into this and i can see the following on logs of my router: [code]
so it seems that the router tuns off its DHCP capabilities because it detects that my Cisco switch is running DHCP services. I need to figure out how to keep the billion routers DHCP running when ever the switch is turned on.is there a way of filtering out any DHCP chat from the switch to the router?
I have 5 linux and 3 Microsoft 2008 Servers, each connected to 2 Cisco 3560 Switches. The 2 Cisco 3560 switches are connected to 2 different Cisco 515e Pix. Is it possible that if i enable Port SPAN in any of the switchport and send a copy of traffic to any of the windows 2008 server, will i be able to monitor the bandwidth of the servers (Here I am only looking for traffic going from servers to PIX and then to internet, also vice versa).
Also will wireshark be able to differentiate specify the bandwidth of each servers seperately ?
I'm intending to purchase a switch for work,and I need to limit the bandwidth of one of the ports to 25 Mbit upload and 25 Mbit download (we have 100/100 Mbit connection and the customer is only paying for 25). I been trying to find information on how this could be "properly" done and what kind of switch I need to buy. As far as I have understood, most L2+ switches support outbound rate limiting, but not inbound, and as I only want the customer to have 25 mbit up and down, I need both.
I been looking at a Cisco Catalyst 3560 switch, and I'm first and foremost wondering if I can limit the inbound AND outbound bandwidth on this switch? Perhaps it can even be done on a simpler, cheaper, switch - as I rather not spend more money then necessary?
Lastly, how to do it, limit the inbound and outbound bandwidth on a single port (perhaps on the above mentioned switch, if possible), to 25 Mbit?
We have quite a few 3560 & 2960 on our edge network - what I have been looking at was to access switches via web-interface i.e. web-browser. Only problem with this is it always gives you access on privilige level 15 which is not ideal as not all who we decide to give access to these switches will be admin and allowed to configure these swicthes - In the 3560/2960 data-sheet states:
"Alternatively, a local username and password database can be configured on the switch itself. Fifteen levels of authorization on the switch console and two levels on the Web-based management interface provide the ability to give different levels of configuration capabilities to different administrators"
Where as there is no mention of how to configure these two levels of Web-based management in the configuration guide.
Is it possible to enable an absolute value rate limit using QOS on a HP ProCurve 5406 switch for a particular IP range on a specific port? Is there a way to configure our HP 5406 with an absolute rate limit on "WAN" port for that server's IP range? I would like to limit it to only being capable of sending 1Mbps worth of traffic over the head end at once.Everything in the documentation points towards priority queues, which as far as I can tell, isn't really what I want.Baring accomplishing this goal using rate limiting is there a better way to prevent our services from accidentally saturating this connection?i thimkong about somthing like that:
class ipv4 rate-limit-port-A1 match ip 10.136.0.0/16 any exit policy qos port-a1-ratelimit class servers-to-be-slowed action rate-limit kbps 1000 exit interface A1 service-policy port-a1-ratelimit inI'm not sure about this.
I want to limit the bandwidth going to remote site on the switch connecting to our netapp.We have a 4 port channel group setup on our 3750x switch going to our netapp storage. We have a Wan 100mb link to our remote site and we want only 60MBs of that link to be used for Netapp traffic all other local traffic needs to use the full amount of the bandwidth to the netapp.
Is possible to allocate bandwidth in this way and how would I go about this? We dont have access to the routers for the link and they plug directly into a port on our cisco.
We are planning to go for HSRP redundancy for 32 VLANs. Means In a Cisco 4506-E switch , we will configure 32 vlans and among them 16 vlans will be primary and 16VLANs will be standby ans it is viceversa in another core-switch
My querie is How many standby groups can we create in Cisco 4506-E switch, Is there any limitation..
If there is any limitation , can we go ahead with VRRP,GLBP? Are there any limitation in VRRP/GLBP? Is there any design related issue can we face if we use same group number to all VLANs?

I have issue with 3560 switch QoS configuration . I checked in cisco site about mentioned model QoS configuration.once we mark the frame and map the CoS to DSCP and once it enters into switch and it processes according to LAN QoS configured on interface
we have configured both the commands shape and share.
once it leaves the switch and enters into Edge router and if we do not have configured QoS in router which is normally MQC , how does it process each packet ?Do we need to have end to end QoS configured in LAN ?
I have the attached setup. now i would like to limit my ftp transfer to 10 mb from a specific vlan to ftp server on the STM-4 (622) link. what would be the best way to limit ftp traffic to 10 mb .Video_Main#sh verCisco IOS Software, IOS-XE Software, Catalyst 4500 L3 Switch Software (cat4500e-UNIVERSAL-M), Version 03.02.00.SG RELEASE SOFTWARE (fc4)Technical Support:
