Cisco WAN :: Configure QoS On 877 Router To Give Priority To Voice Packets?
Dec 6, 2010
I'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

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.

I'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.

Just got the DIR-655 and was wandering how to prioritize the wireless connections, that way my future mother-in-law across the street will be last. I can get the Static IP for a computer, but when I go into the router settings for QoS, I don't understand what info goes in there.

My web browsing/surfing speed decreases when I'm transferring files between other computers which are connected to this modem, and when a torrent client is downloading from 20+ seeds. I want to give the HTTP connections (port 80) the highest priority possible, so that my connection wouldn't delay when non-HTTP connections are active.The interface of the modem related to QoS settings are as below:What QoS settings should I enter (what rule(s) should I define) for giving HTTP protocol higher priority?

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 need to configure two voice-enabled cisco routers, each one has an analog FAX machine. The routers are connected with a serial connection. In the end, the faxes should be able to fax to each other.The fax uses RJ-11 and I've established that I will be configuring FSX ports. (These ports are used for analog devices such as telephones, modems, and fax machines). I am unable to find a single site that gives information about specifically configuring fax machines.

In QoS, voice traffic is usually marked EF and placed in a priority queue. But interactive video traffic, like VTC, should also receive priority treatment. Can I put both classes in their own priority queues in the same policy map? I thought there could only be one LLQ, but I'm not sure about it. An example of the config I'm thinking of is below. Voice would be marked EF, VTC would be marked AF41.

How to configure ASA not to drop packets with ip option 7 (record route)? According to the docs, ip inspect ip option will drop all ip option packets except 0,1,and 20 (EOOL, NOP, or RTRALT):
"If an IP header contains additional options other than EOOL, NOP, or RTRALT, regardless of whether the ASA is configured to allow these options, the ASA will drop the packet. "
Also, policy-map type inspect ip-options treats only these 3.

I want to configure QoS for voice traffic over a site-to-site VPN tunnel. I have a Cisco 851 router on the branch end and a Cisco 1800 router at the HQ. The setup is an Avaya Gateway located at the HQ and the idea is that the phones at the branch office are connected over the VPN tunnel to the gateway at the HQ.
I have a 1MB internet link at the HQ from a service provider and 256kbps internet link (from a different service provider) at the branch office. The branch office has just 3 users.

Is there any way I can tell if an network priority is setup on the router? The last week or so the internet has been unusually slow sometimes, and not slow at all other. I don't have a good relationship with my roommate (network administrator) and I feel she may have put a network priority on the router for her and or her boyfriends computer/s. Is there any way to tell? Is there a particular way in which the internet behaves when a priority is set? I just don't want to pay for the internet if it is not going to work most of the time.

Why is it that the dhcp on my router is no longer able to give out ips or rather it assign them as for as it concerned as it will list say 199.170.0.102 but the device will have none or make up one for it's self and never get the ip that the routers dhcp gave it this happens on all devices. I know power cycling will fix it temporally but usually it will start doing it again in a few hours also I know that I can use a static ip this was my way around this problem but I have one device that won't use nothing but dhcp a printer. I had an old linksys router that did this and I figured it's old it's slow time for a new one after a few months it started, some computers are on the fringe of being able to get a signal but are still fair also even with static ips they sometime stop connecting and we have to disable the connection then reconnect to fix it the router is a dlink 615 dual band set to only G/B because 1 most devices only g 2 the one computer that has a wireless n is 70 ft away and works better with g.

I recently have been reading into QOS and have been fiddling with it on my Linksys WRT54G router. But there are a few things that seem limiting (at least on this version) so I have some questions.I live in a house with three other roommates all sharing the same internet connection. We don't have a bandwidth limit, so I don't care how much they're downloading. When I want to watch Netflix when they're all on the internet however, either my movies will come up in low quality, or will be interrupted.Under the Device Priority I put in my MAC address and set my priority to high. My first question is, what is the priority of a device that is not listed at all? There's only room for two devices so I can't put all three of my roommates in. I would assume their priority would automatically be the lowest.
I wanted to set certain common ports to be at a high priority. So far I just have port 53 for DNS entered with the highest priority, while my computer is set to high. Would this mean any computer making a DNS request would have a higher priority than my computer making a non-DNS query? I would like DNS to be a higher priority than myself streaming video.Finally, are there are ports that streaming video commonly use? I know there are ports for Netflix but I was also thinking of other Flash/HTML5 videos I might come across. Or do they tend to just use port 80?

RVS4000 router doesnt give out an IP address to a client connecting with QVPN v1.303, connection seems good, router logs the connection and tracks its duration etc but client side does not get an IP from the RVS4000 side -keeps local LAN ip + there is no access to the remote shares etc. RVS 4000 has DHCP enabled. Client side subnet is different to the VPN side. VPN users are setup correctly (Router logs the user as connected) . Port 443 is not setup in port forwarding.

Today, suddenly my internet went down so I checked up on it and I found out that something might be wrong with my router. I can connect just fine if I connect my computer with the modem directly but when I plug the modem to the router, I can connect to the router but it doesn't give me any internet.

I bought the router E2500 and I followed the steps for its configuration. It so happens that most of the time I turn on my router, it does not connect to microcomputer, because it loses the internet settings, requiring that I turn the CISCONNECT and after that, I have to turn off the microcomputer, wait for 2/3 minutes and then reconnect, for only then will be able to surf the internet. I notice that many times even I doing all this procedure the router does not give access to the internet. What should I do?

Just recently got a Zyxel VSG1432 router connected to the main computer in my home. I am now trying to connect my laptop wirelessly. It will connect to the router but says it is an unidentified network and it doesn't connect to the internet. There is an x in the network and sharing window.I have tried restarting the router, going to the router webpage and resetting to factory settings, none of this worked. Also contacted the service provider and spoke with two tech guys, but still no luck.

I've got threeLinux Boxes (running Centos 6). They were all connected to my cheap WRT54GL-- DHCP worked every time.Absolutely no problems. Both the LInux boxes and the WRT54GL had MTU set to manual, 1492.I replaced the WRTt54GL with the expensive E4200. I set the new router's MTU to manual, 1492. NONE of my Linux boxes ever receive a DHCP address. I look at the logs, and they do DHCPDISCOVER, get DHCPNACK, try several different intervals, and then fail the interface and quit.ALL I did was unhook cables from the WRT54GL and plug into the E4200. Yes, the WRT54GL was powered off. NOTHING was changed in the Linux configs. Yes, DHCP is enabled, address-range assigned, etc. BTW-- one box is dual boot with Win7-- in Win7 (using the same card, obviously), DHCP works just fine. But, Linux doesn't work.
I can give the boxes static IP's, and all is well. Just can't get DHCP to work. I evfen tried putting in DHCP reservations (via MAC assignments) for the E4200-- still doesn't work. The new E4200 is on the 02 firmware (which I believe is cuurent). If I can't iron this simple task out, in a couple of days I'm taking the E4200 back, and getting a refund. I'll stay with my old WRT54GL... it works. Hate to give up on some of the new E4200 features, though.
