Cisco WAN :: 3825 - What Does Shape Average Percent Mean In QoS Policy
Jan 3, 2010
I am working at a client site that is an MPLS customer. The customer has an MPLS circuit that runs between their Main HQ and their Disaster Recovery site. I have been asked to analyze and report as well on the way the Qos Policy is written, and to provide any recommendations on how they can improve performance.There is a statement within the Qos Policy as it exists at each end on the 3825 routers. The statement is called "shape average percent". Here is the policy from one side:
policy-map QoS
class COS2_traffic
set dscp af31
shape average percent 12
bandwidth percent 13
[code]....
What does this statement mean and how is it different than the the "bandwidth percent" statement?

I have a asa 5510 with 8.x software and I want to reserve (i mean RESERVE not PRIORITIZE) traffic based on protocol, like if I have a 10Mbit I want to :
- give 3 Mb for smtp
- give 5 Mb to http/s whatever
- 2 Mb for other stuff.
Of course QOS won't do that, can you do that with ASA?

What is the average memory usage for a Cisco 5508 with 500 APs (mostly 3502s) running 7.0.116.0 code? I am currently at 450 access points and have 80% memory usage should I be concerned?

At my workplace, we have high speed internet (dsl). We don't have Wifi or a full time tech guy at the moment. I was thinking about proposing it since I generally handle most of the technical items at my job, but wanted to verify a few things first. First of all.. on a work network.. is it any more difficult than your average home network to set up a wifi router? Anything special I should know before attempting to set one up?

I'm attempting to configure qos on our ASA 5505 and I'm not sure how to determine what our average and burst rates should be.The applications being used will be RDP over a ipsec tunnel, so it is somewhat sensitive to latency.The final setup will be a 1.54Mb T1 line, but in testing I have a DSL connection with .70Mb U/L speed.

I have a bandwidth-intensive video conferencing device connected to a router. I have forwarded all the necessary ports to the device (and I have even tried DMZ) but the device is unable to connect to some servers due to "NAT issues". The device uses lots of ports simultaneously to connect and I am wondering maybe possibly the router can not handle the number of open ports. The ISP only blocks port 25 which the device does not use. Could it be that the ISP limits the number of ports that are in use? Or maybe the ISP limits the amount of bandwidth that can pass through certain ports?

I am quite new to WCS and preparing a demo for a client. I am also using WLC2125 with LAP1252s for this setup. Is it possible to modify the shape of the heatmaps of the APs? I know how to regulate TX power of the radios and all works great but how can I controll RF leakage outside the perimiter of the building? Is it possible to controll the RF so that it will not be going outside and same time giving a good coverage inside?

I have a Cisco 2821 with ios Version 12.4(21). On that router I have a WAN link that is 550mbit dual. The interface is 1000FD so i need to shape my output traffic to max 550mbit - otherwise my ISP policing is dropping the traffic.
I've looked at this document url... and i'm trying to use this interface command:traffic-shape rate
But the router wont accept rate value 550000000 that should be 550mbit in bits/s
Is it not possible to shape the traffic to 550mbit on the 2821 router?

I have ASA5510. It's include security plus license.I want to traffic shape to 200Mbps. But , I checked a CCO.CCO said that a shaping limit is 154400000. "Enables traffic shaping, where the average rate argument sets the average rate of traffic in bits per second over a given fixed time period, between 64000 and 154400000. "It's mean shaping limit 154400000 ?Can I shape to 200Mbps ?

Recently I want to apply traffic shape on my ASA5520, but after entering the configure mode of policy-map, I couldnot find the shape command.. If I type the command, the device would notify me that there is no such command.. My version is 8.0(2),PS. Police command is working fine...

We currently "need" to shape certain services very specifically....we curently do this via routers for CE's (881's etc) i.e. 10Mb service, we need:
-class class-default
-shape average 9800000 40000 0
Some of our clients want to run firewalls as CE's that are unable to shape to this degree, so we are wanting to put an inexpensive switch in front of their CE to do the shaping for them(L2 - either per-port or per-vlan)...the ME3400 looks ok, but is quite expensive.

Is it easy to setup a paid wifi hotspot or would I need knowledge of advanced networking? I've been searching around and I've found software that do that, I prefer doing it free.

I have been reading for awhile now on all the Cisco forums on the 3560 and shaping egress traffic but I wanted to verify my thoughts on this. I have 3560 that connects to the ISP that is policing at 10Megs, I want to shape my egress traffic going to the ISP, I do not want to provided QOS to any specific traffic type but only shape all traffic outbound. Will my config below shape "all" egress traffic going to the ISP on the 3560, on a port that is physically connect at 100Meg Full duplex?
int gi0/1
srr-queue bandwidth shape 40 40 40 40
I gathered these numbers using the formula of 100* 1/weight, which would equal 2.5 and if each queue has 2.5 meg that would = 10Meg. However another concern is that I don't think I have the full 100Meg on the interface to use (correct?)

I am having a Cisco 4507 switch. The CPU on the switch is running between 50% to 60% constantly. To troubleshoot I collected some logs using debugs & show commands.
debug platform packet all receive buffer
show platform cpu packet buffered
debug platform packet all count
show platform cpu packet statistics
show processes cpu sorted | exc 0.00
show platform health
show platform cpu packet statistics
show platform health output shows the below process crossing the target value.
%CPU %CPU RunTimeMax Priority Average %CPU Total
Target Actual Target Actual Fg Bg 5Sec Min Hour CPU
Stub-JobEventSchedul 10.00 13.41 10 47 100 500 13 13 10 5462:52
K2PortMan Review 3.00 5.35 15 11 100 500 4 4 3 1799:47
What I need to know is, though these process are running in Low Priority, will there be any issue if the CPU goes high due to these process.

We have two offices connected using Site-to-Site VPN (IPSEC) as shown:(IP ficticius)Office 1 - We had to use 2 routers since we have a range of valid IPs: From a host in office 2 we normally ping 192.168.102.1 (gateway at office 1),But when pinging a host inside office 1 (eg: 192.168.102.8) 50% of packets have been lost.Could it be a hardware problem?

I have two switches that always are with yours CPU in 39 or 40 %. the switches are:
IOS (tm) C3500XL Software (C3500XL-C3H2S-M), Version 12.0(5)WC3b, RELEASE SOFTWARE (fc1)
I think it's very strange the CPU always in 39 or 40 %. neither all ports of the switches are busy there are 6 ports free in each switch. 40 % I think it is a high value for CPU maybe because my IOS version 12.0 ?

Im running ASA 8.0(3) on Active/StandBy failover pair.Last night I realized the CPU usage of my production ASA was 99%,,, on the ASDM Firewall Dashboard I can see counters like this:
Dropped Packet Rate (ACL Dropped) = 6000+ (more than 6 thousand)
Scanning Attacks = 18600+ (more than Eighteen thousand)
I went on the ASDM and checked the RealTime Log viewer and I have about 30 entries per second of these:
4Oct 19 201111:35:12401004Shunned packet: 10.64.10.1 ==> 10.64.0.1 on interface NewLAN

I have ATT DSL and pretty much every night, I lose a large portion of the Internet. I cannot ping these sites, while the rest of the net works fine. The other night, I could not ping major domains like ATT, CNN, MSNBC, BBC (a chronic missing domain). On the other hand, I could get Yahoo fine and go to a streaming audio site and run music perfectly...but about 90% of the Internet was unreachable. Could not load their sites nor ping them in command line. The other 10% worked flawlessly.

I installed a CSC-SSM-20 module on ASA 5510. After policy services have been enabled, services works well for a few minutes, after that the cpu usage's module rise to 100% and all http traffic is wholy blocked, till the cpu usage go down.This happens very frequently and traffic stay blocked for such a long time that it makes the csc-ssm module unusable. It's disabled right now. ASA version is 8.2(1)and CSC-Module version is 6.6.1172.0.

We have a client that has a large number of AIR-AP1252AG-N-K9 installed in the network with power injectors. We have seen a about 48% failure rate of AP's failing with all 3 red lights on the unit. Once I get the AP in the lab I'm unable to get any response from the console, therefore unable to troubleshoot.
