anyway to implement priority marking on the voice packets on the IP communcicator which installed in a laptop (running Data VLAN in the switch)?
View 1 RepliesI'm trying to configure QoS on my 877 router to give priority to voice packets. However, when I do a show policy-map for WAN interface, all the classes show 0 bps. When I do a show int for the WAN interface, I get the correct bandwidth util.
This 877 is meant for a home network. I'm running a Cisco 7970 phone using phone-proxy back to my HQ. I'm also shaping the traffic.
Here is my config
Class Map match-any EF (id 1)
Match ip precedence 5
Class Map match-any class-default (id 0)
Match any
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 some point-to-point sites linked with our HO with 10-30mbps speed. We have provided DID telephone lines to these sites as well.
We want to limit the bandwidth with 1mb bandwidth only and also make sure that the voice traffic (DID telephone lines) gets the priority over all other traffic even if they are utilitizing the 1mb link completely. We have some Cisco 1841 routers that we are planning to configure on the main uplink on each of these sites. how to give the priority to the voice traffic yet limiting the bandwidth to 1mb.
Trying to set-up a priority queue for Voice and Video traffic, below is the current ASA config. The WAN link is 6mb, trying to limit the Internet traffic to 4mb and save 2mb for the PQ, config belowTraffic just isn't hitting the PQ

I need to get some low volume, interactive data, prioritized on frame relay PVCs across our network. I have followed the CBWFQ examples from cisco.com, but my test packets are still showing latency over 1 second. My lab set up has a corporate connected gateway router linked via FE to testrouter 50. TR51 has a T1 frame relay loop to another router acting as a frame relay switch. The other side of the FR switch has a 56k link to testrouter51. I am sourcing test pings from my desktop PC, that are marked as AF43, and leave at a rate of 1/second, when the response comes back in time. I am using a Smartbits to generate some default class traffic at a rate of about 56Kbps only in the 'outbound' direction, toward TR51, as this emulates a file copy from corporate to remote sites, that is causing the AF43 traffic to suffer. Here is the relevant config on the TR50 device:
class-map match-all rtu-data
match ip dscp af43
!
policy-map frame-56
class rtu-data
priority percent 20
class network-mgt-data
bandwidth percent 5(code)

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?
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 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

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.

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?
View 5 Replies View RelatedI 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?

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

I just wonder if there is simply way on Cisco 800 to set bandwidth priority for internal IP address. Basically I have server and would like to make sure, whatever comes to it or goes out has the highest priority and users won’t kill bandwidth for the server connection.
View 7 Replies View RelatedI am fairly new to Cisco, but am trying to configure a 1921 router to give higher priority to SIP/VoIP traffic (Port 5060) than everything else.The connection is only 4Mb and is getting hit hard by video streaming, I don't want to block this, just make a lower priority.Any ideas where I am going wrong?My current config is as below.The IP addresses have been changed for security reasons, but in reality are both in the same range, i.e. are both external IPs, so I am not sure if this is causing the problem. Do I need NAT for QoS to work?

2)Is it possible and if yes how i could made such scenario: I've got existing netwirk with two wlc 4402, i want to join third wlc 5508 and new access points, but i need that new access point joins to wlc 5508 first,and if all licenses used,jins to wlc 4402 second. Or where i could read about it?
When I ping my video streaming host's IP address (the IP that they gave me where I can view my IP web camera's video stream), I get anywhere from 0% to 8% packet loss at various times of the day. They're claiming that there's no problem, that this is because this is a router and it's dropping ping packets due to "ping priority giving preference to more important network traffic."
View 7 Replies View RelatedNew to the forum and not much Cisco IOS experience let alone on the security side of things. I know how to navigate the IOS and can do basic switching and routing just fine. My company currently has a DMVPN setup w/ about 10 tunnels going back to the hub. We have 4 more sites they want me to setup and I keep getting stuck at the crypto maps. I have been reading about VPN's, DMVPN's , etc. for days now but can't find any examples of how we are configured. The priority of our crypto maps start at 65536 and go up. Default max is 65335 from what I have read, and I cannot assign a priority that high statically. [code]
View 3 Replies View RelatedI've got a LAN with private IPs for the computers, and public, static IPs for the VoIP phones. They are a Hosted VoIP provider, and I want to give priority to the public IPs with my ESW-520-48P switch. How do I implement that in this switch?
I have no roles assigned on the ports and no VLANs setup either. I had tried segregating the VLANs first, but eliminated that route. It's all VLAN 1 now in the switch again. For some reason when I implemented VLAN 100 for voice, voice stopped working on the phones, but data was still fine.
I have a known working configuration with many sites and one operative center that receives all communications.The connection OF THE OLD SITE is here detailed:Now I need to integrate another site. The difference between the old site and the new site is the following:
-old site communicates with the operative center by means of the FE0/1 or by means of an HWIC4T serial interface.
old site automatically switches between the tunnel on the ethernet interface (FE0/1) and the serial channel giving priority to the ethernet tunnel.
-new site will communicate with the operative center by means of the FE0/1 or by means of a transceiver device connected on the FE0/0.
-both new site and old site have a LAN on the FE0/0 where data is generated and sent to the router to be dispached to the best available channel.
The connection of THE NEW SITE is here detailed: the old site was configured this way: [code]
the first line means that everything starting from the client directed to 192.169.0.2 it will be sent on the tunnel1.the second line tries to route the same packets on serial0/0/0 with low priority.On the New site i did the same:
i created the tunnel form my cisco 2811 to the operative center using the FE0/1, then i added the following:ip route 192.169.0.2 255.255.255.255 Tunnel1
This works as expected routing the packets to the operative center on the FE0/1.Now I miss the second part: route packets on the FE0/0 to the ip address 192.168.1.31 WITH LOW PRIORITY like i did on the old site.
I did some tries but no one solves. Which is, in your opinion, the right command to add on the cisco2811 in order to get the equivalent of what i did on the old site ( ip route 192.169.0.2 255.255.255.255 Serial0/0/0 10 ) ?
Our company had been buying Cisco 1841 routers for years and they have served us well. The 1841 was discontinued and instead we have now purchased a Cisco 1921. It is brand new, running "Version 15.0(1r)M15" of IOS ("usbflash0:c1900-universalk9-mz.SPA.151-4.M4.bin" file).
On our older Cisco 1841 routers, we would always prioritize certain TCP and UDP packets using the priority-list command. However, I have suddenly discovered that priority-list is not available on this brand new router. (?) I am unsure why. I did some reading and according to the document [URL], and priority-group are unsupported in Cisco IOS 15.
Later version of a product isn't as fully-featured as the earlier version. I want to prioritize the following type of network traffic.
UDP ports 8000 through 8063, 2427, 2727, 9300, 9301
TCP port 35300, 60001 through 60010, 2065, 33333, 3065
giving them a higher priority than the rest of other packets. This is necessary for our vendor's VoIP implementation. These packets should be "high" priority; everything else can be "medium."
Can we implement BGP without IGP Protocol ? If yes, then how can we do it ? If no, why ?
View 11 Replies View RelatedWe are attempting to implement an ASA 5520 with a new ISP. Based on the limited routing needs, I believe we can use it as the router as well. I am familiar enough with routers, but the ASA is obviously a different thing.

2) DMZ 0/1 connects to outside switch with servers (Public)
3) Inside 0/2 is LAN (Private)

B) What should the interface security levels be, I am unsure what they should be or why...?
Based on the initial config with interfaces set as above, I cannot move traffic through.
Today we have a simple ASA-5520 SVC setup with just one connection profile and one group policy. Authentication (2 factor – AD + SMS) is performed by RADIUS. We would now like allow access to this VPN service only if you reside in a particular group in the MS AD. From what I understand this can be accomplished through DAP. Either by matching the LDAP attribute “memberOf” or RADIUS id 146. I’m I right? Can I still perform authentication using RADIUS and then DAP using LDAP or must I use DAP using RADIUS?
