We have a guest wireless setup but I need to rate limit the users so no one hogs all the bandwidth. The WLC is connected into a 3750 which is doing all the routing between the vlans. I know I cannot shape the traffic on the 3750.

I am trying to limit traffic inbound to 10Mbps on a gig interface 0/48 set to 100/full. So I downloaded some big files over this link and I'm able to see 30- 40Mbps or more. You can see from the show int - rate-limit command that parameters are never showing exceented so nothing has been dropped. [code]

I have verified that the policy is attached to the interface and the settings are correct as well.

We have a number of 6509s which generally have dhcp relay agents configured on the SVIs. The dhcp servers are centralised. Recently we've had one or two faults with misconfigured or faulty devices (blade server chassis and also printers) generating high volumes of dhcp discover packets and causing high cpu on the relevant 6500. I would like to rate limit these discover packets, which are layer 2 broadcasts. Storm control can't discriminate between different types of broadcasts and on a gig link would need to be set down at about 1% to have much effect on the problem. I've looked at CoPP and also mls hardware rate-limiting but as I understand it, these two features don't control broadcast traffic. I also looked at dhcp snooping but if an interface receives a high level of dhcp discover broadcasts, e.g. over 100pps, I don't want it to go error-disabled (as this would knock down the whole edge switch), just to drop the excess packets.

i was wondering if the "srr-queue bandwidth limit 10" command would work to limit the output from this interface to be 10 % of the port bandwidth and then the same command could be done on the other side.
If I have an interface configured as follows (on a Cisco 3750 Switch)
Interface gi 1/0/24
Bandwidth 100000
And then added the following command
srr-queue bandwidth limit 40
Would the result be 40% of the physical 1Gbps interface or 40% of the 100Mbps Bandwidth set under the interface bandwidth command.
I have a 3825 with a 16 port etherswitch card installed that I'm trying to setup rate-limits on. Interface G0/0 is the connection to the outside world and int g0/1 has a couple of 2950 switches attached to it.
The etherswitch card, f1/0, f1,1 etc has corresponding vlans, 902, 903 etc each with an IP 10.110.1.x, 10.110.2.x and all part of access-group 111. The switches connect on sub-interfaces g0/1.101, g0/1.102 etc and have IP's 10.55.1.x, 10.55.2.x and part of access-group 101.
What i'm trying to achieve is that every port / IP that is on access-group 111 shares 3Mb of bandwidth in/out and access-group 101 shares a separate 3Mb of bandwidth in/out.
I've created two access-lists as follows;
access-list 101 permit ip 10.55.0.0 0.0.255.255 any
access-list 111 permit ip 10.110.0.0 0.0.255.255 any
And on int g0/0 I've created the following rate-limits;
rate-limit input access-group 101 3072000 64000 64000 conform-action transmit exceed-action drop
rate-limit input access-group 111 3072000 64000 64000 conform-action transmit exceed-action drop
rate-limit output access-group 101 3072000 64000 64000 conform-action transmit exceed-action drop
rate-limit output access-group 111 3072000 64000 64000 conform-action transmit exceed-action drop
Now instead of both access-groups having 3Mb each they all seem to be sharing 3Mb! I've tried class-maps and policy-maps but to no avail..

I am looking for information on how to properly configure rate limits on a Cisco 2821 so that I can set different Service levels by IP address. For example I want to limit a block of IPs to 1 Mbps Down and 512 kbps Up. I am doing point to point networks from our router (ISR 2821) to another router that is assigned a static IP. The other router connects to our router through a Fast Ethernet port on a NM 16 port switch card. The routing end point for the network is on a VLAN interface. Currently we are using bonded T1's but are about to turn up a Metro-E circuit.
View 1 Replies View RelatedI have configured a vlan interface on a 3750 switch. there is aprox 4Mb active traffic flowing through the interface, but when I do a "show interface vlan (vlanid)" the output show zero bits in and zero bits out. Its a typical L3 config with one IP on the vllan interface acting as the gateway for the VLAN devices. Is this a normal behaviur ? and if so is there any way to get the traffic in/out stats. The end PC/devices are connected to this switch via an L2 TRUNK and I dont have access to the L2 switch on which the actual devices connect. so cant get the real time stats of those interfaces.

My question how can i route the traffic from the server to the end user , as the the server is not direct connect to the core switch.
I have used the following basic configuration to do rate limiting on a vlan interface on a 6509:
access-list 100 permit ip any any
class-map match-all ratelimit
match access-group 100
policy-map ratelimit-10Mb
class ratelimit
police 10000000 428750 conform-action transmit exceed-action drop

How do I combine the two correctly to give me a vlan port rate limited at 10Mb up and down, but still setting aside (dynamically) 2Mb for voice?

We're running on an 1871 right now that is not under my control so I can't even see it's running config. OK! So when I set my gateway to be the 1871, we can get our upload to over 6mbit (we have 8 branches, so won't ever get full 15 since they're using it too). With the gateway set as the 1921, it seems like we're stuck at 1.5. I haven't seen it go higher than that. I've looked over the config but can't see anything that would imply some kind of bandwidth limit but I have copied the config here.

View 3 Replies View RelatedWe have been deploying 3502 APs remotely to locations with full T1s that backhaul to where I sit at HQ. Both the foreign and anchor controller are here at my location.
I am seeking to rate limit per user the bandwidth each client will get on the guest internet ssid. As you know this traffic is encapsulated in capwap between the AP and the controller so I cant use a standard ACL on the switch or router.
We are trying to keep the guest internet access usage in check on the T1 at any given site so the other ssid's & local lan traffic is not overly competing for the bandwidth.
I found the place to edit the default profiles in the controller but the documentation really isnt clear on best practices.

View 4 Replies View RelatedHow 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?

View 8 Replies View RelatedI am having an issue with VoiP phones giving me an insufficient bandwidth message. I have three remote locations connected to our main building using 2 Mb point to point ethernet solutions through TWC. Each remote location has a Cisco WS-C3560-24PS running IOS C3560-IPBASE-M, version 12.2(25) and have the cable modems plugged into port 1 on them. The remote buildings are labeled 192.168.101.xxx, 192.168.102.xxx, and 192.168.103.xxx. There are 14-16 VoiP phones in each remote building. The main building being in the subnet of 192.168.100.xxx. I have the 3560s connecting to a single port on a 2801 in the main building, all using the subnet of 192.168.253.xxx The phone server sits in our network at 192.168.100.203. I have created the ACLs, class maps, and policy maps on all of the equipment.
For the remote buildings I have the following:
ACL

permit tcp any host 192.168.100.203 eq 5566

However, I have been receiving phone calls from people in the remote buildings stating that their phones will cut out, flash Insufficient Bandwidth on the LCD displays and then the call will cut back in. I am wondering if the 2801 is not applying QoS with the rate-limits in mind since it is set to 100 Mb, or is it an issue with trying to take 3 remote locations and bring them down into 1 port on the 2801?
