Cisco WAN :: 7200 - Egress Netflow V9 And Output Packet Marking Order
Aug 17, 2011when 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

Cisco WAN :: Which DSCP Marking To Use For Ex90s
May 17, 20111) which DSCP marking to use for ex90s(HD video)?
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?
Cisco WAN :: 877 - Policy Map Not Marking Packets

Cisco WAN :: QOS Marking Query Of 7206VXR
Nov 2, 2011We 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.
Cisco WAN :: 3725 / Marking A Traffic With AF31
May 29, 2012 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.
Cisco Routers :: SRP521 DSCP Marking On QoS?
Jun 14, 2012I 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.

View 1 Replies View RelatedCisco Switching/Routing :: Nexus 7000 QoS Marking For Both DSCP And COS
Jan 29, 2012I 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?
View 5 Replies View RelatedCisco WAN :: 3750G - Loss Of DSCP Marking When Routing Between VLANs
Jun 8, 2013I 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?

Also, the laptop upstairs that the family uses sometimes can't connect to the router, so I have to unplug then replug the router for the laptop to connect to the router. Is my router giving up? Its a G router, should I shift over to N anyways?

Jan 18, 2012I seem to be having packet loss with the E4200V2 which is upgraded to the latest firmware as of today, 1/18/12
The application is accessing a security DVR which uses a RTSP / RTP stream. Of course this requires certian ports to be forwarded in order for this to work. This works flawlessly with a WRT310N or a Cisco 871 Router so I know the port forwarding is correct.
With the E4200V2 it works intermittently, I can replace EV4200V2 with either the Cisco 871 or the WRT310N and there are no issues.

Mar 9, 2011A while ago I bought a WRT320N as a trade-in offer, unfortunately I had around 20% packet loss on my connection after I set it up. If running directly through my cable modem I had no connection issues at all.I was running the whole setup cabled, and have no peripherals using the wireless connection.The router was returned to the retailer for RMA, and in the end I got the purchase credited.My setup ISP: Dansk Kabel TV (danish provider for internet, TV etc.)Modem: Netgear CVD31T DOCSIS 3.0 compliant Cablemodem (I do not have access to the modem, as it is provided by the ISP. I have now bought an E2000, and set it up in the same manner as the previous router.This has returned the same problems I had with my previous router.Updating the firmware didn't make any difference.Using Pingtest.net as my test reference I get results like this.when connected directly to the modem I get 0% packet loss, max 20ms ping and jitter is 2-3ms.Have I been so unlucky to get 2 faulty routers in a row, or could there be some problems with Linksys routers and Netgear?I have unsuccessfully tried switching cables without any change, tried moving the router "far" away from the modem, monitors etc to see if there could be any interference from the wireless.

Dec 6, 2012We have a remote site connected to ADSL line with a Cisco 887VA router attached. This has been working fine for the last couple of months. However, recently, the site have started to complain of performance issues (network slow, applications disconnecting, etc)Looking on the router, we can see evidence of packet loss/timeouts from a simple ping to the internet e.g. [code]
However, we have logged the fault with our service provider and they return all line tests as clear but what is particularly strange is that they also report “and the SNR Margins are well within threshold levels (Upstream 11.5 and Downstream 15.0)” which, unless I’m misunderstanding something, seems to be completely different from what the router itself is reporting.Is there a reason why the service provider’s stats for Noise Margin would appear to be so different from what the router is reporting?
