QOS for inbound traffic on 3560
Just to clarify what I'm asking.... I would like to make the congestion happen on our end and not on the ISP's equipment that I have no control over traffic shaping etc... I can't limit the bandwidth on the aggregate port that the metro e connects to (3750) because it would limit it for all locations and not just one. I think my only option is to limit the bandwidth on the switch at the location in question but I guess it would have to be on the ingress side, but then will it still drop packets according to dscp priority during congestion?
I have a little problem I hope you guys can help me with. We have a location that has a metro e hand off from our ISP. The same metro e also serves other locations and the aggregate point is at our main office which goes to a Cisco 3750 stack. The location in question has a single Cisco 3560 switch. We need to apply QOS for both inbound and outbound traffic to this location. I can tag the traffic to and from there but how do I make it so that the 3560 (or 3750) gets saturated and not the ISP connection for incoming traffic (so we decide what packets get dropped)? srr-queue bandwidth limit can't be used on the metro e port on the 3750 because this would limit all locations and not just the one.Should I put another small switch and put it in from of the 3560? This way I could use srr-queue and apply QOS to the egress queue.I hope this...

I have two 3750ME switches connecting two ends of a LES100. On each switch, i have 3845 routers with the NM-CEM-4SER modules, plus direct to switch internet traffic. My complete setup is as shown in the attached PDF.
My problem is that with the default QoS settings, i have lots of drops in the Txqueue of the switches.
The CEM's send traffic as EF, which is trusted throughout the switch setup. Other traffic that comes into the switch is marked down to best effort. Thus, most of the traffic the switches handle is EF,(about 70%, 20MB for now). How do i tune the QoS parameters on the switch to handle this amount and more of EF traffic?Regaring the QOS, I think we should implement this on the 3750 . It is worth advising you to first upgrade the IOS on this device. The following URL will help you:
http://www.cisco.com/en/US/docs/switches/lan/catalyst3750/software/release/12.2_25_sec/configuration/guide/swqos.html
As you are unable to specify the "bandwidth/priority" on 3750 cli, you will need to use the Queuing and Scheduling (SRR) section from the config guide. So basically you enable the expidite queue for the CEM traffic egreesing the 3750. However I believe you cannot classify the traffic via acl to assign it to queues, so you will need to mark it. -

Yes, I do.
laugh - I was temped to stop with the above, as it directly answers your question, but I assume you want to know how.
In principle, you recognize the VoIP traffic as being different from data traffic and provide it "special" egress treatment. Normally you would enable QoS, and for egress, enable PQ, direct VoIP bearer traffic to that queue. You might also direct VoIP signalling traffic to a queue that insures it's not unduly delayed or dropped. You might also set rate caps on ingress VoIP traffic.
Recognition of VoIP traffic can be done in different ways. Your phones might support L2 CoS or L3 ToS marking, your switch might "analyze" ingress traffic, your switch might trust a Cisco VoIP phone, your switch and VoIP phones might use a dedicated VLAN. Basically, there's lots of variables dealing with ingress.
Unfortunately, you've provided insufficient information for specific recommendations.
PS:
BTW, your 2960 might also support auto-QoS, which may, or may not, be all you need to enable. -
Cascade Catalyst 3560 switch for loaded traffic
I have a layer 3 Catalyst switch 3560 with 24 FE interfaces.
I need to pump traffic from traffic generator into port 1 and propagate it to other ports; the last port will be connected back to the traffic generator.
I suppose that I need to cascade some of the switchports but how do I configure the catalyst switch for this setup? Is it making use of routed port and static routing?Hi Ankur,
Thanks for the reply.
The traffic generator are layer 3 interfaces which I can assign IP address.
You mentioned that I do not need any routing, but I require traffic coming from the traffic generator(e.g FE1) going into switchport 1 to traverse through the rest of the switchports before exiting from the last switchport back to the traffic generator(e.g FE2). Therefore, I need advice on how to setup the catalyst switch to achieve this.If I assign ip address for this traffic to end at the traffic generator-FE2, the generated traffic will enter the switch at switchport 1 and directly exit from the last switchport without any traversing done. Btw, do I need to cascade my switch with cross cable in this aspect?
Thanks in advance for your advice.

Hello all,
I have a campus network with several remote sites, at the campus I have a 6509 at the core and 3560 and 3750 switches at the access layer. I do have QoS enable on the 6509 and I am using auto QoS on the 3560 and 3750 switches and all seems to be working fine with my existing VOIP environment. But now as I am in the middle of rolling out a video conferencing solution with the existing QoS config I am experiencing a noticeable delay between audio and video. Example like during a video call I can tell that the voice and the lips of the person speaking are not in synch.
Has anyone run into this issue ? can someone provide me a sample QoS config for the 6509 and 3560/3750 switches ?
P.S. I am using a Tandberg/Codian solution for video conferencing with Tandberg/Codian MCU, IP Gateway, ISDN Gateway and Tandberg endpoints. And both the endpoints and the back-end infrastructure devices and are set for IP Precedence 5.
Thank you very much in advance !!!
DannyThe main concern with configuring your back-end infrastructure devices with IP Precedence value 5 is that the 3560/3750 auto-qos will map this value to Q1 which is ordinarily the strict priority Q.
In most cases auto-qos will also configure or map Video to Q3, you can see this as a majority SRR bandwidth is assigned to the Q.
In order to use the strict priority queue, it has to be enabled on the interface 'priority-queue out', without it Q1 will not be emptied before the others. It will be serviced according to the weight.
With auto-qos Q1 will not have enough bandwidth as it will be assigned to Q3. Therefore you could initially enable priority-queue if not already enabled so that Q1 is emptied first, or you increase the weight.
The next question is whether you are using egress scheduling within the Core? and this conforms to your edge classification for Video?
HTH.

VoIP QoS for Site-to-Site Tunnel
Hi all,
I need some help with setting up QoS for VoIP between two Cisco ASA 5505 with Site-to-Site VPN.
There is no need for bandwith reservation, only DSCP 46 (EF) should be highest and DSCP 26 second highest queue and the rules should only apply to a site-to-site VPN.
Usually i try to configure the ASAs via ASDM and found out in the Cisco Documentations how to setup QoS for the DSCP bits with a Service Policy and how to set up QoS for a Site-to-Site VPN (Service Policy Rule -> Traffic Match). But how do i configure the QoS for a DSCP bit to only apply to a Site-to-Site Tunnel? And how do i configure different priorities for the two DSCP bits, is this defined by the order of Service Policies?
The QoS has to be enabled on both ASAs for the inside interface?
Thanks in advance
TobiasHi Collin,
ok so from the document i think this has to be added on both ASAs to prioritize DSCP 46. Could you have a quick look if this is all i need?
class-map voice_traffic
match dscp ef
class-map data
match tunnel-group <Tunnel Name>
match flow ip destination-address
policy-map voice_policy
class voice_traffic
priority
class Data
police output 200000 37500
service-policy voice_policy interface outside
But there is still the question how two configure another DSCP bit for priority 2, I could not find out how this is done, neither CLI nor ASDM. Any ideas?

To configure a QoS for the attached topolgy
Dear friends,
I have to configure QoS for the attached topology with the following requirements, can any one please help me to do the same.
The minimum requirements are that 4 simultaneous VoIP calls need to be supported across the backbone, as well as a dedicated 10MBs of http traffic. Of the remainder of the bandwidth ftp traffic should be given a high priority. Make sure routing protocols are given a suitable priority level.
Thanks and expecting repliesHere are some questions that you'll need to answer, to get started.
What does the HTTP requirement mean? It is not possible to get 10 Megabytes per second on a 1.544 Megabit per second line.
What voice codec will be used on the IP Phones? This will determine how much bandwidth you need to allocate.
Next, read the following link:
http://www.cisco.com/en/US/docs/ios/qos/configuration/guide/12_4t/qos_12_4t_book.html
It's all in there. Unfortunately, it's a big topic, so there is a lot there. -

Try to remove etherchannel configuration by taking ports to it's defaults and also interface Port-channel68.
Then create port channel interface by first issuing :
interface GigabitEthernet1/3/10
description SAC88
channel-group 68 mode active
interface GigabitEthernet2/3/10
description ECM DELEJ02SAC88-D20
channel-group 68 mode active
Then configure all stuff around switchport under interface Port-channel68. -

in the feature set for the IOS currently running it suggests this configuration should work, however it will not apply the policy via the Cisco-AVPair command (the command is visible via the debug AAA per user so radius is working, even when we test it by applying the service-policy to the actual virtual-template it errors saying it will only work on an MPL bundle. From what I have read it is suggested that even though this feature is supposed to work, it does not in practice and an upgrade to a feature set which includes QoS:per session shaping and queueing on LNS is needed.
If anyone has any experience of the or has any suggestion of if we can achieve our QoS for voice per session with the current IOS that would be great.This feature is not related to the NPE type. This feature is performance impacting so you should do some tests to see if your NPE-400 can support the number of L2TP tunnels you want with this feature enabled. If it's not the case, you will have to upgrade your NPE.

RV110W Blocks all inbound traffic
I have a RV110W that's been in service since Dec 2012. All Everything is working fine except every month or so the firewall starts blocking all inbound traffic. It does not respond to remote management access. If I reboot the firewall (pwr off/on) everything works correctly for the next month or so and then it begins blocking all inbound traffic again. Local access to the Internet and VPN tunneling are not affected. When it's working, all my rules and port forwarding work correctly. Anybody seen this before?

Inbound traffic alert (ESET) - Application: System
I have a MacBook Pro (Retina, 15-inch, Mid 2014) running OS X Yosemite 10.10.2
I have installed ESET Cyber Security Pro a while ago, and an inbound traffic alert just popped up. "A remote computer is attempting to communicate with an application running on this computer. Do you wish to allow this communication?"
The application involved is "System", local port is TCP 8770. The remote computer is fe80::4c8d:97ff:feb4:5d8d, remote port is 56398.
I am still new to Mac, and therefore I'm not sure if I should allow or block. I thought that it might be system updates, but not too sure about that so I'd rather wait for an answer before proceeding.Port 8770 is used for the Digital Photo Access Protocol, which in the case of a Mac means sharing of photos. I'm not sure exactly how this port is used in Yosemite, but you can bet this is just another Mac or iOS device on your local network querying your Mac to see if it is sharing any photos. It is very unlikely that you have a network configuration that would even allow a truly "remote" computer to connect to yours over the internet.
ESET is wasting your time here. Uninstall it, and see my Mac Malware Guide for more information about protecting yourself from malware.

That is right. QOS and bandwidth profile functionality is for outbound traffic and traffic over VPN, and using QOS you should be able to limit bandwidth for outbound traffic and traffic over Site-to-Site VPN.

AutoQoS for voice traffic settings?
Hi Everybody,
I have enabled auto qos on switch and following are information
Voice is the most important traffic in network, must ensure voice traffic goes first
SW# show mls qos map dscp-output-q
Dscp-outputq-threshold map:
d1 :d2 0 1 2 3 4 5 6 7 8 9

SW# show mls qos queue-set
Queueset: 1
Queue : 1 2 3 4
buffers : 10 10 26 54
threshold1: 138 138 36 20
threshold2: 138 138 77 50
reserved : 92 92 100 67
maximum : 138 400 318 400
For the
DSCP 46 : it's 01-03 (voice)
DSCP 0 : it's 04-03 (general traffic)
From my understanding
- 01-03 means queue 1 and threshold3. (by default threshold3 is 100 and hidden)
- queue-set 1 is enabled by default on all interface and hidden
According to the above information,
- Does the Auto Qos is design for voice goes first?
- Why the Q1 buffer and maximum are less then Q4? isn't suppose to set more buffer on Q1 for voice traffic? or I have to re-distribute the queue buffer and threshold, etc...
- or I just use priority-queue out, then those queue setting will be ignored?
Thanks in advance

VLAN prioritization for SAN traffic
I have a stack of 3750's running two VLANs, one for NFS traffic (id 130) and one for iSCSI traffic (id 150). I have jumbo framing (MTU 9000) on VLAN 150. I'd like to try prioritizing the iSCSI traffic using 802.1p. Can anyone point me to some configuration help? Does anyone have any thoughts or experiences with this idea? Thanks!
The MDS GE/iSCSI interface can set the DSCP value on outbound IP packets, but that is in the IP header (layer 3). From what I recall, the 802.1p bits are in the Layer 2 field between the MAC addresses and the Ethernet type, and from what I understand, the MDS does not provide any marking at that level.
You could mark via 802.1p inbound on the Ethernet Switch that the MDS GE port is attached to, but not directly out of the MDS GE port.
If you are interested in marking iSCSI using DSCP, here is web page describing how you set the iSCSI interface for the desired DSCP value.
Hope this helps,
Mike
