Cisco Switching/Routing :: 3560 Rate-limit Vs Policing And Shaping

Nov 27, 2011

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.

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

Mar 8, 2012

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:  
ISP - ASA - ROUTER - LAN 
Policy map: 
Policy Map shape-lan
[code].... 
 
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
  [code]....
 
Should I just be increasing the queue-limit or should I be changing something else?

Cisco Switching/Routing :: 6513 Span Session Limit?

Jul 12, 2012

I have a need to capture some traffic but my core 6513's are already using the limit of 2 span sessions. I can't edit any of the sessions either because I want to source traffic from vlans and you can only do one or the other. Is using a VACL with 'switchport capture' on the destination interface an option ? E.g. I want to source traffic from vlan 10,20,30,40 and send the all to interface Gi10/10 ? Is there any caveats ? I dont need to be too granular with the ACL's but just capture all traffic in those vlans.

Cisco Switching/Routing :: Rate Limit 3560 Outbound To 5mb?

Jun 9, 2013

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?

Cisco Switching/Routing :: WS-C3560-24PS - Rate Limit And QoS

Mar 4, 2012

I 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
===========
Extended IP access list VOIP
permit tcp any host 192.168.100.203 dscp ef
permit tcp any host 192.168.100.203 eq 5566

[Code]....

I have put a hub in to capture traffic via Wireshark to see if DSCP flags are being appropriately marked and I do see that all VoiP packets are getting marked with as EF.  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?

Cisco Switching/Routing :: Rate Limit Trunk Port On 3750?

Oct 3, 2012

Is it possible to rate limit on a L2 trunk port on a 3750?
 
current port config and ios are as follows;
 
interface GigabitEthernet1/0/50
description ***  Connection to Fiber Link  ***
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1,172
switchport mode trunk
end  
flash:c3750-advipservicesk9-mz.122-46.SE.bin
  
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.

Cisco Switching/Routing :: 3750x Switch Port Rate Limit

Oct 8, 2012

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.

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.

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 :: 6513-E / 6513 And WS-X6748-GE-TX Compatibility

Oct 29, 2012

we have a chassis 6513-E and a module WS-X6748-GE-TX, I'd like to know if could I put this module in any slot, since the documentation from Cisco says that any slot from a chassis 6500-E Series can support this module. And then in the documentation of WS-X6748-GE-TX says that this module is not compatible in the slots 1-8 of the 6513 chassis, only from 9th to 13th slots, in those slots from the 6513-E we already have 4x WS-X6748-GE-TX, and we'd like to know if could we put the module in the rest of the slots. The 6513, and 6513-E is kind of confusing.

Cisco Switching/Routing :: 800 Series - Limit Monthly Traffic On 3G Access

Oct 29, 2012

Is it possible to configure a limit on monthly traffic over a 3G access on a Cisco 800 Series?
 
The scenario is that a customer has a Cisco 800 3G routers with a 3G card from a Service Provider, that offers a rate for X Mbytes per month and that when those monthly X Mbps are exceeded, a differente rate (much more expensive) is applied for the excess traffic that month. The customer would like to have the router NOT to active the 3G access when the X Mbytes (on that month) are exceeded. Maybe this is possible to implement using a TCL script and ip accounting?

Cisco Switching/Routing :: 3560 - Traffic Only Can Achieve Half Of Limit Bandwidth

Jul 15, 2009

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.

Cisco Switching/Routing :: 3750 - Show Interface Vlan (ID) Doesn't Show In / Out Traffic Rate

Mar 13, 2013

I 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.

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 :: Rate Limit On 3750v2 SVIs

Dec 6, 2011

I have a stack of Cisco 3750v2 switches with 8 VLANs (one per customer) and 8 SVI's (again, one per customer).  I am trying to apply rate limiting to the SVI's of each vlan for both input and output traffic.  This is my SVI configuration for one such VLAN (I have substituted the real IPs for prviate IPs for the purposes of this example) -
 
interface Vlan30
description ****CUST-C-VL30-SUBRATE-CAR-10M****
ip address 192.168.30.250 255.255.255.0

[Code]...

Based on this and the speed tests I am performing from within the VLAN i am receiving the full bandwidth and not what should be assigned based on the rate limiting.  Have I missed anything as far as the configuration goes?

When I configured a test setup in my lab (multicast camera source and a few routers) and tried the command it simply did not work. Moreover, when I went to use the command on a 3900 router in my lab, it was not there.
 
I take it this command has been deprecated?
