Cisco Switching/Routing :: Asymmetric Bandwidth Limit On Cat2960 Or 3560?
Apr 9, 2013
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.
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 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
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 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 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.
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 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 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?
Brand new 2960. When I plug a cable into the port, nothing happens. The port light doesn't begin negotiation or anything, it just stays dark. The cable works fine--I have it on another switchport with a crossover connector connecting to a little Cisco SOHO switch without problems.
I've done the following: switchport switchport mode trunk switchport trunk allowed vlan 1 no shutdown
In other words, I've fiddled with it. But I don't know why it doesn't light up..
I have a Cisco SG 300-20 as the core switch, layer 3. It is 192.168.4.6 on VLAN1 and 192.168.5.1 for VLAN2 (VOIP). All the ports are set in trunk mode. DHCP relay is setup on this switch.
The phones connected into a layer 2, Catalyst 2960-S switch. All ports are set in trunk mode. Default gateway on it is set to 192.168.5.1.
DHCP for both VLANs is provided by a Windows Server 2008 R2 server (the relay IP 192.168.4.15).
There is also an ASA 5510 in the mix which is 192.168.4.1. It has a route added to it for the 192.168.5.0 network to go to the SG 300 (192.168.5.1).
Just the two switches can ping each other on the 192.168.5.x network when I "add vlan 2" to the trunk port that is connected between the SG 300 and the 2960. The phones don't get DHCP on the 2960 switch. And I cannot ping 192.168.5.x from the ASA or anything else on the 192.168.4.x network.
After a bit of reading on intra-vlan routing for the SG 300 switch, I am thinking the SG 300 has to be the "center" of things so I need to make it 192.168.4.1 to be the gateway for both VLANs and change the ASA to 192.168.4.2 for VLAN1, etc. And I really can't do asymmetric routing with this switch.
I am planning to buy a router for my hotel and I would like to know is it possible to limit the bandwidth limit to the guests? And the admin computer can utilize the maximum speed? it it possible to create a login page paper when some one enters my wifi connection?
I am a Network admin of 200 Computers.Most of our users used to download movies through torrents.I just want to now how can i limit the bandwidth for specific user for both domain and work group user
Is there a way to limit a whole PC windows XP, or a certain program to use only a certain about of your total internet connection bandwidth?For example, I have 5 PCs in home all one the same ISP connection. I have one PC that I am trying to backup files online but I can only run it at certain times due to the backup program using ALL upload/download speed. And that makes every other PC super slow.
When we do self diagnostic test for WAE connected to the 6500 switch i get warning as below. Due to this alert there is no major acceleration benfits by the WAAS
Test WARN [tfo] WARN ASYMMETRIC Asymmetric routing is seen in the device Action: Check router's network configuration and WCCP redirection on the router.usevwa1#
6509 switches has only L2 capability and does not do WCCP redirection. The WCCP re-direction is done by 2821 routers.Is there any command which needs to be given in 6500 switch to solve the issue
I am using ASA 5505 cisco firewall as a transparent firewall. I have assigned ethernet 0/0 as outside interface and ethernet0/1-7 as inside interface. There are 3 departments in office. So, i connected ethernet 0/1 to Dept A, ethernet 0/2 to Dept B and ethernet 0/3 to Dept C. Now, I want to limit bandwidth to each department, e.g, 1 Mbps download/upload to Dept A, 512 kbps download/upload to Dept B and 512 kbps download/upload to Dept C. So, how can i do this in ASA 5505.?
If two (one 6509A 9/26 with server A located in A end, 6509B with serverB located in B End) which is connected via a 1G link. If there is serverA send 700M file to server B via a 1G link. If I configured below command to 6509A 9/26, can I limit the bandwidth of server on bothincoming and outgoing to 500M?

I have a 3845 Router with three connected interfaces, one to my WAN, one to my LAN and another to my wifi zone. I want to limit the amount of WAN bandwidth the WIFI zone can take to say a max of one third and not restrict WAN bandwidth from the LAN at all.
I have cisco 7600 core router in ISP , i want to put the bandwidth limit on it for outgoing traffic (for internet) on a subnet because i am using Bluecoat and i want to test my bluecoat.On this subnet i have no limit for bluecoat but after the bluecoat i want to limit it. On 7600 cisco router i have not rate limit command so how it can be possible for a perticular subnet ?
