I am running 1.1.24 and spa303 phones I have a qos policy setup to mark all packets
The following is my qos
information 192.168.1.15/24
makring enabled
cos/DSCO DSCO
Value 0xb8
On my upstream device I only allow traffic that is marked with this dscp value. No traffic is coming through. RTP traffic is marked because it comes off the phone marked but I would expect the qos Policy so mark everything going to that ip space to be marked.
2) as a test we are planning do to deploy ex90 at few of locations. at location 1 we will do DSCP EF marking while at the other location we will do DSCP AF41 for video..assume, LOC1 calls LOC2: so, when video traffic from LOC1 arrives to LOC2 will it be marked as EF? and when traffic from LOC2 arrives LOC1 then traffic will be marked as AF41? if yes, then will there be any issue sometimes in case if we run out of bandwidth for EF?
i did on cisco 2960S switch at user ingress interface. but the marking is not showing in show policy-map interface gig 1/0/10 interface and ACL is not showing any match.
I also had a config reference from 2960S cisco guide.
access-list 103 permit tcp any any eq 80 access-list 104 permit tcp any any eq 23 access-list 105 permit icmp host 172.24.68.4 any
I have a pair of Nexus 7K's running 5.1(3). I have a handful of edge devices that I need to mark ingress traffic, and need to mark both DSCP and CoS. Right now, I have a working config that marks DSCP appropriately.While that works dor DSCP, the MQC will not allow me to mark both DSCP and COS in the same class, and unlike IOS, it appears that Nexus does not have a default DSCP-to-COS mapping. My understanding is this can be solved using table maps, but I don't see how that can solve my problem in this specific scenario (it appears I can do marking or table-map mutation, but not both?). How I can accomplish both?
I have a 3750G switch running 12.2(44)SE6 my customer has some Cisco EX90 and ex-Tandberg VC units connected to the switch in a dedicated VLAN 600. The switch is then connected to the WAN router which has its own VLAN 6
From sh mls qos interface x/x/x statistics I can see that the traffic is marked by the VC units as DSCP 34 however when I run this command on the interface to the CE router the marking has been lost.
Similarly in the opposite direction incoming from the CE router I can see the marking coming from across the MPLS ok but when I check the output to the VC unit the marking has been lost.
This would indicate that in the process of routing between VLAN's the DSCP marking has been lost.
how to correct this issue. Because my interfaces are in different VLAN's do I need to VLAN based QoS?
I have a srp521 and want to set it up as a vpn server so I can connect back from outside.On the router under the vpn tab I only have
Site to site IPSec VPN IKE Policy IPSecPolicy GRETunnel VPN Passthrough
Page 191 of the srp500 manual says Click VPN > Cisco VPN Server > Group. The Group window opens The manual also says only the serer or Site to site will work at one time, so where do I make the change to bring up the vpn server option?
I have a customer with a Sonic wall that I want to replace with a 521.He currently has port forwaring setup so that only 3 ip addresses can access the port forward. Everyone else is dropped. Is there a way to do something similar?I can make it work for a single one via the DMZ tab with a source ip address. but there is not a way I can find to add the allow for the other two remote connections.
I'm having problems configuring an IPSEC VPN between an SRP521 with a dynamic IP and a ASA5505 with a static IP. Static to Static is fine between these devices and I can configure that without problems. Dynamic to Static however.
I have a weird issue with a QOS policy that I have implemented. Details are below.
This is basically the policy I have created. It is running on a Cisco 877 router (running Advance IP Services 12.4). The internet connection is an Internode ADSL service.
class-map match-any VOIP match access-group name VOICE-OUT ! !
We have subscribed for MPLS links from Service provider we have a DC where the core connectivity is 90 MB and Remote branch location Connectivity is 64 Kbps. We are in process of enabling QOS for our links with co-ordination with Service provider ; as per our finding the branches have more RX traffic (downloading) so after discussion with provider we were advised to mark traffic from the core end and give it to the provider.The provider at its PE will honor the marking and set some B/W percentages and prioroty based on the DSCP marking values.
We need to mark this traffic so it is feasible to mark the traffic at the core DC router which has the below H/W details,Cisco 7206VXR (NPE-G2) processor (revision A) with 917504K/65536K bytes of memory. Processor board ID 36161439 MPC7448 CPU at 1666Mhz, Implementation 0, Rev 2.2 6 slot VXR midplane, Version 2.11
or is it feasible to mark the traffic at the core switch.
I have a Cisco 3725 router with IOS version "Cisco IOS Software, 3700 Software (C3725-ADVIPSERVICESK9-M), Version 12.4(12)". And this router is serving as a CE route for our MPLS connection to the service Provider. We do also have multiple VRFs ( around 10) and the WAN interface is DS3. So we created point-to-point subinterfaces and we put them in different vrfs. We have now transitioned to a new ISP and the ISP requested us to mark all of our outgoing traffics with DSCP AF31. So I have created the following policy-map
policy-map TRAFFIC-OUT-WAN-AF31 class TRAFFIC-OUT-WAN set ip dscp af31 class-map match-any TRAFFIC-OUT-WAN match any
Now we do have multiple GRE tunnel interfaces sourced from one of the WAN subinterface ( which is a member of VRF A). So the moment I applied the the policy-map on this WAN sub-interface (using the syntax "service-policy out TRAFFIC-OUT-WAN-AF31"), most of the GRE tunnels went down. And there is eBGP running on top of these GRE tunnels.
I want to mark traffic on Cisco 3020 switch entering to interface gigabitEthernet 0/1 ingress direction with DSCP values. interface gigabitEthernet 0/1 is in access mode and in vlan 10.
when using egress netflow (v9) and output marking.
The topologie : Server <-----> R1 1>-----<1 R2 2>----<2 R3
R2 is a 7200 with c7200p-adventerprisek9-mz.124-15.T11.bin What I'm doing :- R2 forwards ping packets from Server to R3. When they arrive on R2, icmp packets are marked with CS3
- I change the DSCP to CS4 on R2 before forwarding packet to R3. I'm using for that an output service-policy on the R2-2 interface like this : interface ATM2/0.36 point-to-point
ip address 192.168.1.1 255.255.255.252 ip flow ingress ip flow egress
in switch 2960s ( c2960s-universalk9-mz.122-55.SE5 ) , i want to marking the traffic between two hosts (Data replication), i choose to use " mac access-list" to classify my trafic before apply the policy marking . but did'nt work . c

I am wondering what is the TOS value equivalent to DSCP value AF31? I am wondering what is the TOS value equivalent to DSCP value AF31?I have tried to use the charts but I couldn’t understand how to convert it.
I ran into interesting issue on Sup-2T. As you probably know, QoS CLI is changed on this new supervisor. I'm looking to translate incoming dscp-marked packets, into exp-marked on egress.Now, according to documentation - Catalyst 6500 Release 15.0SY Software Configuration Guide - this functionality is still called mutation-map and is configured under 'platform qos map exp-mutation'. The problem is quite simple – there is no 'platform qos map exp-mutation' on 2 different machines I checked upon. Here:
Some-6513(config)#platform qos ? 10g-only qos pure 10G mode aggregate-policer Named aggregate policer marking marking keyword police police keyword protocol protocol keyword queueing-only queueing-only (no QoS rewrite, no policing) rewrite packet qos rewrite enable/disable statistics-export qos statistics data export
I work in a manufacturing firm where we have offices at 3 different places say A,B and C. Our ERP server is at our original unit A from where we accessed it at B and C through remote desktop application till now. But now we have hired cloud services to connect to our main ERP server. We are in the process of installing the cloud application on our server at B during which we are encountering a problem. The cloud service provider is asking for domain name and password for the DSCP server based at the orignal unit (A) which no one in the company seems to have any idea about. Our IT guy at A has resigned and has not been replaced. Our IT guy at B is inexperienced and just following the instructions of service provider who is stuck at DSCP domain name and ID. How can I know the domain name and password of DSCP server so that the process moves on?
According to product bulletin no 3209 for the Cisco 4400 series, the Access Point supports 802.11e WMM.
My question goes to DSCP mapping, according to IEEE and your bulletin the DSCP field in the IP header should be set to 46 (10110 00) for mapping to a 802.11 QoS voice priority 6/7.But my Wireshark trace revealed 4400N is mapping toward with 802.11 QoS is set to Priority 5 Video.
If I google DSCP mapping toward 802.11 QoS all IEEE documention I found says EF /Voice should have 46 or 101xxx in the DSCP IP field but running through Cisco and HP docs gives 46 or 48 as value, that is the correct value. [code]
I am getting a very strange problem where 4500 switch is remarking the packet with dscp 1 to 0.
Let me explaint the setup. I have two PCs connected on same switch but on different modules. PC1 is conencted to Gi4/19 and PC2 is connected to Gi2/43. Both the ports has been configured to trust the dscp. Below are the configuration:
The Cisco 3560 uses a relatively simple classification scheme, assuming you consider only what happens when the forwarding decision has been made. These switches make most internal QoS decisions based on an internal DSCP setting. The internal DSCP is determined when the frame is forwarded. What internal DSCP setting means?
following about a limitation on the ASA5505.I have a client that has a number of branch offices on a Gen-I OneOffice network. For complex and political reasons, we can’t trust all nodes on that OneOffice network. We need to put a firewall at each branch office between their local network and the OneOffice router.
To avoid having to either readdress the OneOffice routers (politically difficult) or readdress each branch office (logistically difficult) we’ve suggested using a transparent mode ASA5505 firewall between each sites OneOffice router LAN switch.
Recently I’ve discovered the client is deploying Avaya VOIP phones into the offices using QOS/DSCP over the OneOffice network from Avaya units in some offices. I figured I’d need to trust DSCP on the way though the ASA and went about looking at how to achieve that.
I found the following document relating to configuring QOS on the ASA: url...
This suggests in the DSCP and Diffserv Preservation section that “DSCP markings are preserved on all traffic passing through the ASA.” However, in the Guidelines and Limitations section it suggests QOS isn’t supported in transparent mode.I’m a bit worried that the DSCP markings won’t pass through the ASA5505 in transparent mode.
I have a problem with the command mls qos trust dscp, I used the ios c2800nm-ipvoice_ivs-mz.124-25f.bin but i can not enable dont show me the complete command in the interface Ethernet o Giga. I want to configuring mls qos trust dscp.
I want to know what the default behavior about the command 'mls qos trust dscp' under router platform interface. the router is ASR1000 series.we don't need to put above command line to trust dscp in case of router? otherwise, we have to add it as welll as like switch platform.
there is something I find strange on C6500 about QoS: C6500 derive an internal DSCP value for it's internal use, but when configuring the qos mapping on output interfaces, only a cos value (I guess, an internal cos value) can be used. Is it a misunderstanding from me, or is it really illogic?
I've been working on a 3560 that doesn't seem to map dscp values to a new value: mls qos map dscp-mutation ToR1 22 24 to 46
[Code]....
On the router on the other side, I created an acl that matched on dscp 46, but it doesn't match on it. I've tried moving the mutation map to the ingress interface and I've tried setting dscp with a service policy instead of marking COS and using internal dscp. Where is the mutation map supposed to be placed: ingress or egress? Also, I added an entry in the acl on the router to see if I was mapping to dscp 24, and I am:
[Code]....
So it seems like the mutation map is being ignored completely. Any reason why?
I am reading through a QOS Document and they want me to trust the DSCP value from an IP phone (Siemens) but UN trust the PC DSCP value. How can I trust one thing but not the other? I am using a 2960 Cisco switch with IP base IOS.
