Cisco WAN :: 2951 - QoS For Voice On Multi-Link Frame Relay Interface / Subinterface
Jan 10, 2012
QoS on an MFR interface/subinterfaces. We have a remote site with two bundled T1's terminating on a 2951 router for a total bandwidth of 3072. The circuit is provided by Paetec and the subinterfaces are designated for internet and MPLS traffic respectively. The issue we are facing is with outbound voice quality. It seems that no matter how we apply QoS, either to the main MFR interface or the MFR subinterfaces, voice packets do not seem to be prioritized. We tried FRTS, which slowed the entire link down to a crawl, we tried applying a class map to the main interface as well as a service policy, none of which seemed to affect anything.
class-map match-all VOICE
match ip dscp ef
class-map match-any SIGNALING
match ip dscp af31
match ip dscp cs3 (code)
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)
I 'm trying to set up a home lab with a couple of 28XX and 2651XM series routers.I would like to simulate a frame-relay connection between HQ, Branch1 and Branch2 . All of them are conneced to a PSTN switch (2811 router) via T1 cross over cables. The connectivity is like this. [code] I have configured all the routers and FR switch with necessary configuration. However the link between HQ and Branch1 is not coming up. On both the routers I could see the line protocol is down.I have pasted the configuration below.[code]
I can ping R2 to R5 but not R5 to R2. I have spent about 10 hours going through my network and code to no avail. I think it is the frame relay that's causing the error but not sure.. I just checked and I think R6 and R5 are not getting their OSPF updates by trying show ip route
Main site have 8 departments and each department have 60 pc's,remaining sites each have 6 departments and in each department have 40 pc's and in the design of WAN connection you use frame relays and that is the 100% growng hosptals and clock speed is 64000 bits/sec and security must don't access the unautheraised users from out side....how can I do this?
Provider T1 handoff with two PVCs to their MPLS cloud to a 2911.One Internet PVC and one for the MPLS including a SIP trunk .
Is there a way to use QOS to have the router prioritize one PVC over the other.Always service the MPLS/SIP PVC over the Internet ONLY PVC?The MPLS/SIP PVC will have QOS for voice but needs to be prioritize.Other option will be to police down the Internet PVC to a value which will leave the required total Kb for the voice priority KB.(FR PIPQ works if the PVC is for voice only.)
I am having real problems trying to build resiliency into a hub and spoke frame relay scenario. I know the hub is a single point of failure. Is there any way to put some resilience into the network? There is 4 attached branch offices.
working through a lab and can't seem to configure frame relay on subints. I assume it's not supported but this seems basic; am I doing something wrong?
I have been trying to make rip work on this frame relay with multipoint configuration (hub and spoke) and I also configured a loopback interface on each of the routers and configured rip with the loopback address. I observed that the routers (cisco 3600 series) are not sending or receiving any RIP updates through their serial interfaces but are sending through loopback interfaces i configured (debug ip rip).I can ping all routers but cant ping their loopback interfaces because RIP updates are not sent or received by them.
R1#debug ip rip RIP protocol debugging is on R1# *Mar 1 00:09:46.759: RIP: sending v2 update to 224.0.0.9 via Loopback1 (1.1.1.1) *Mar 1 00:09:46.763: RIP: build update entries - suppressing null update
I started studying yesterday for CCNP Route and I'm already stuck. Stupid Frame relay. Basic topology attached, 1 Hub, 2 spokes. I have EIGRP working correctly and each spoke can see all routes correctly. The Hub is on a Multipoint interface with split horizon turned off.
I've a home lab which consists of three 2610xm routers and I have configured two routers back to back with FR subinterfaces. The commands are used are;
R1 frame relay switching int s0/0 encap FR no sh clock rate 64000 frame-relay intf-type dce
[code].....
Everything works great with this config and I know how to configure without lmi too. My question is more for the CCNA exam and fill the gaps in so to speak. The question is when you configure FR with static mappings and inverse arp do you need actual frame relay switches on the other side of the link or can I configure on my home labs routers. I know I am gonna try and configure this as well, but can I configure multipoint on my third router with a different physical interface. Like R1 with s0/0 to R2 s0/0 and R1 s0/1 to R3 s0/0 with subinterfaces.
I am installing an ASA 5520 and I have a problem on accepring the incoming traffic from an external office connected via Frame Relay.
On my OUTSIDE interface I have both the internet traffic and the external office traffic incoming. What comes from the external office is visible as 10.1.0.0/16.
I have to allow this traffic to enter the internal network, without any control. I would also keep the original IP address.
I have configured the Firewall but I don't know how to setup the NAT.
I'm looking to test fram relay connections in a lab environment i'm building at home. I have a couple of 2610 routers that are barebones and am looking to get some serial modules. Are (2) WIC-2T's all I would need to create those test connections? Also on a side note are the any modules for the 2610 that have fast ethernet connections. I would like to have that so I can create a router on a stick model off of the 2600's.
I am trying to setup my new 2901 running 15.1(4)M1 for frame realy via a VWIC3-1MFT-T1/E1 card. Now I have set up plenty of frame relay connections via older serial cards, but I just cannot find any documentation on how to do this on one of the new VWIC3-1MFT-T1/E1s. None of the commands I am used to seem to even exist. None of the
We have frame relay T1 circuit at one of our remote site. Which is connected to our core frame relay router which have DS3 circuit.Now we bought second T1 line at remote site and now I have to configure Bounded T1 with Cisco 1921 router.good config example or document on how to configure frame relay bounded T1 ?
I have a 3845 running 12.4.13a which I want to upgrade to 12.4.24.After upgrade one of the interface that is configured for frame relay doesn't work anymore.In fact is the "service-module t1 timeslots" commands that can not be executed and the router throws that error.I tested this behaviour on two 3845s and the result is the same.Is this a bug or is an workaround for it?
Transitioning from 3825 to 3945 (OS is 15.0(1r)M13 c3900-universalk9-mz.SPA.151-4.m4). Turning on FDL on the 3825 was easy but the same command on the 3945 doesn't work.
I have a NM-1CE1U working on my router 2600 , configured with frame-relay . But seems it does not work on my router 2811. I have check that the replacement is HWIC-1CE1T1-PRI , right ？
But the problem is these two modules have different interface type , I want to keep my cable interface type and find one module card working on 2800 or 2900 router , can configure frame-relay.
I have catalyst 3750 I want to controle traffics on every port I have tried Frame-Relay Traffice shaping and Quality of service but there is no support for these commands in the switch.do we have any way to limit traffic on every port in catalyst 3750 and 2960 switches ?
We recently purchased the Cisco Router 2951 router with the IOS 15.0. I have tried to put in my VIC2-4FXO card in it. When I did show invetery, it detected the card.[code] When I tried to configure the voice port by typing voice port, it shows % Invalid input detected at '^' marker. I have tried to reset the cad and replace with another one.
Application is that need to configure the VOIP with the existing Frame relay network ,where VOFR command is not shown in the router when type yhe command router config#dial-peer voice 123 need vofr On the 3945 router where in the router it is not accepting the above command,
I want to configure multilink between two Cisco 7206 routers POS interfacesafter configuring both sides.Router 1interface Multilink5 ip address. [code]. I can see both sides through show cdp, also ospf process goes to FULL stateBut traffic is not flow between interfaces, and i can not even ping router's own ip address.When i delete network statement from ospf process, i can ping router's own interface and both routers can ping each other.
I have a circuit that will be delivered to a client next week and we are installing an ASA 5585x for them. They will have a circuit coming in with a few VLANs configured on it. One VLAN for the Internet and one for connectivity to another client.
So does the ASA allow you to create the "outside" interface on a subinterface?
Having an issue that we have with a CISCO2951/K9. It connects to Internet through the GigabitEthernet0/1 interface. Since a few days ago, the Gi0/1 interface is flapping many times in a day:

We have a new optical fiber connection from a new ISP (only for Internet) and we found that our Cisco router RV220w won't work with this new connection because is not possible to add the V LAN ID 20 for the WAN traffic, as required by our ISP/connection. Now we would like to know what Cisco routers can support this feature and that can be "similar" to the RV220w or if there is another way to solve this problem and maintain our actual RV220w, because the features on this particular router (apart of the V LAN ID on Wan) are more than enough for us -
We would like to have a “simple” router and with firewall and VPN features as RV220w, because the one that our provider says that works seems to be too much for us Cisco 2951-SEC K9 – We are a small company with a network of around 10 computers and we only need some VPN connections for our sales companies in Europe and workers when traveling (3-5 VPN connections are OK).
I have removed an embbedded service engine modole from an 2951 router, after reboot the rouiter. the service engine interface still appears; any command can I use to completely remove it.
Cisco 2951 w/ HWIC-4ESW IOS 15.0(1)M5 #sh ip flow int Vlan533 ip flow ingress ip flow egress #
The SVI sends the flow data just fine, however I also continue to receive flow data from most other interfaces.
I have attached a screenshot of one of our netflow collectors indicating that many of the interfaces are sending flow data even though not configured to do so. We have two different netflow collectors, from different vendors and both confirm the same interfaces sending flow data.
Normally I wouldn't care and ignore it, however one of them uses a license limit by interface and is a bit problematic.
We have 6 sites which are connected through E1 links.All sites connected from HQs.
Site A is HQs. Sited B, C, D, E, and F are Branches. Site A is directly connected with site B, C, D and E. Site D is connected with Site F.
Now we have another redundant E1 link for site C and Site F.we are using Static Routes.i have configured Qualified-next-hope on Juniper Router but i am unable to configure IP SLA on Site C Cisco 2951 with IOS 15.0 router.is there another solution for my scenario plz share with me for Redundant Link.
I have configured my two vdsl link with ppp multilink but i am not getting the desired bandwidth. Here is my configuration is this okay or i need something more in the configuration. My router is 2921 what is the maximum WAN throughput of 2921? [code]
