I would like to connect to a 1Gb routed uplink, and then impose bandwidth limits (via shaping/policing/whatever) on a per port basis. The ports could either be configured to route, or as switchports on separate VLANS. I'm trying to identify hardware that will let me do this. The set up I have in mind is shown below.
I am wondering if the IP Services Adv software on that switch will allow that functionality?
Now I have a 172.16.0.0/16 network with a def. gw. for internet where is a MS Forefront TMG 2010 with BSplitter for traffic shaping. I purchased an 2921, 2,5 GB RAM, security+data license and an EHWIC-D-8ESG.
I made 4 subnets in a test environment with some access-lists, nothing fancy yet. How can I use FF TMG for bandwidth management, where should I put it? For those 4 subnets the def. gw. is, normally, the 2921 router. TMG is splitting traffic by client IP.
I 3750 doesn't support "shape" command under policy map. How do I limit the bandwidth to 3 M? [code]

Would the result be 40% of the physical 1Gbps interface or 40% of the 100Mbps Bandwidth set under the interface bandwidth command.

We have a low bandwith (15-20 Mbit/s) to the ASA from our Client vlan. If i connect the Client to the same vlan as the ASA is, the bandwith (90 Mbit/s) is good.
Here are the Layer 3 Design:
Client -> vlan 2 - Switch - vlan 7 -> vlan 1 - ASA 5505 -> ISP
The Layer 2 Design:
Client -> Gig2/0/13 - Switch - Gig4/0/43 -> Eth0/1 ASA5505 -> ISP

I assuming the switch has a problem with routing ?It is a stacked Switch with following members:
switch 1 provision ws-c3750g-12sswitch 2 provision ws-c3750g-24tsswitch 3 provision ws-c3750g-24tsswitch 4 provision ws-c3750x-48
And we have following error message in the log from the switch:
%PLATFORM_UCAST-4-PREFIX:
One or more specific prefixes could not be programmed into TCAM and are being covered by a less specific prefix, and the packets may be software forwarded I first get the idea that the switch is overloaded with router traffic. Thats why i assuming i have to check the sdm templates, but i'm not sure if this resolves the issue.
Here are the relevant config:

View 1 Replies View RelatedWe have a stack of switches that is at the max number of members allowed in the stack. Problem is we are running out of port density and need to add more ports. So instead of adding a whole new stack I would rather replace 2 of the 24-port swicthes with 48-port switches.
If the two 24-port swicthes we are removing are stack members and neither of them are the stack master, I should be able to replace the 24-port switches with the 48-port switches without bringing the master offline? If the new 48-port switches are running the same IOS version as the current 24-port swicthes, they should add themselves to the stack?Would I have to tell the new 48-port swicthes what switch numbers they are replacing in order for them to be added to the stack since we are at the max number of members?Also since the 48-port swicthes are replacing 24-port switches will the master give the 48-port switches the configuration for only the 24-ports?
Is there a way I can find out the amount of bandwidth i'm using on a particular interface on a 4507 cisco multi-layer switch? It is a gig port and I have it setup for monitoring (spanning) and I see packets being dropped in the "Total Output Drops" area. To me it looks like it must be exceeding the 1gig limit but I don't know a way to check to make sure. I also have the queueing strategy set to FIFO.

View 1 Replies View RelatedThe layout of the equipments are as such,other equipment <--> 2911 Router <--> Ether-Switch/3925 Router <--> 7206 <--> Internet,During certain times at night, the 2911 exhibits cpu load, high packet loss and an increase in bandwidth of at least twice it's normal amount. this results in packet loss in all the other equipment. I am attempting to locate who was demanding such a high burst but so far the graphs display normal rates for all the other equipment.Because the 2911 demands an increase from the 7206, the 7206 is able to accommodate this as it still has balance BUT my other equipment that are connected to the 7206 takes a drop in bandwidth as well. the graph shows that when the 7206 bursts higher, the rest of my other links take a slight drop in bandwidth.Also, the graph from Ether-switch to 2911 indicates the bandwidth hike BUT the graph from 2911 to ether-switch does not display the same thing as due to the cpu load, the data is somehow not captured properly.

View 1 Replies View RelatedI was looking at a problem where a traffic from certain sites have a restricted bandwidth, an ongoing problem for a year or so, apparently this throughput never exceeds around 25Mbps. My customer describes a situation where the end to end utilisation rises, eventually flat-lining at around 25Mbps. how many extra systems come on line, this traffic never exceeds this rate, and end users complain of poor responses.
During my investigation I found that one of the switches (Cat 6509) in the traffic path has a policer configured on a vlan interface, the policer has 3 sections for different traffic based on DSCP markers, and a default (unconfigured) class-default. Various people have had a poke about with this config over the years, with the result that all the traffic has the CoS and DSCP tags set to 0. All this traffic is hitting the class-default in the policer.The link that this traffic hits the Cat 6509 on is a 100Mbps link.
If I was designing this from scratch I'd probably configure a rate for the class-default.my question is, in the case where no specific configuration has been entered for the class-default, how much bandwidth is allocated to this class?
I have the following setup:
Cisco 1921 is my core router and connected to it is a 30 Mbit fiberline

I have played around with Rate limit without success.
I also have access to cisco switches that can limit the bandwidth.

View 2 Replies View RelatedI 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.

View 7 Replies View RelatedMy company is composed of three different campuses, all with a similar network topology. We currently are experiencing high bandwidth on our serial interface at one of the campuses in particular. The network is composed of about 20 VLANS routed internally using a Cisco 6509. Traffic to the outside is PAT’d by an ASA 5510 and then forwarded through our edge router interface. Each VLAN is PAT’d to a specific public address.Due to the PAT, how would you recommend determining what specific private addresses are consuming our resources on the serial interface. When I look at our NMS, it reports the public address, but that only narrows it down to a VLAN. For example, all the devices in VLAN 6 are translated to 146.34.118.245, and 146.34.11.245 is a top talker.
View 1 Replies View RelatedCurrently, we have a Cisco router (28xx), ASA 5520, and a core switch 4500. We have different vlans. We also have Auto QoS running for our Cisco IP Phones.My manager just asked me to see if I can either reserve some certain bandwidth for one vlan, or give that vlan higher priority on internet traffic than the others.
1.) Anyway we can reserve some more bandwidth for one vlan than other vlans?
2.) If #1 cannot be done, how can we provide higher priority on the internet traffic to one vlan than the others?
3.) Is #1 or #2 the same config? If not, which one would be easier (without changing our current QoS settings)?
4.) If 1 or 2 can be done, which device I should config the settings on?
5.) This question may be duplicate, but do we need to reset our current QoS to achieve the goal?
