Cisco :: How To Configure Quality Of Service On 2950
Feb 7, 2011
I am trying to figure out how to setup quality of service on my network. At the moment i have computers connected to the PC port of my IP phone and the IP phone connected to the switch.I want the PC to stay on the default native VLAN and the phone to go on the VLAN 10I am using SNOM300 and SNOM360. I will configure the on the phone the VLAN ID and the priority.From my research, there are two ways that I can go about this on the port that is connected to the phone I canswitchport voice vlan vlan-idorswitchport voice vlan dot1pand then I will have to execute the commandmls qos trust cosmy question is which command do i use to configure the ports, and am I on the right track? Also, this is how I configure the ports that the IP phones are connected to, how do I configure the port that my Asterisk PBX server is connected to?

Have customer that we need 3G at new location. Their company is an AT&T customer.So we have got from distribution a 881G and it has a PCEX-3G-HSPA-US card with it.What do you do or need to get AT&T service on this card. You call AT&T they don't know what your talking about if you say Cisco 3G card?I don't see a SIM slot which most AT&T device have a SIM card?Is there somewhere special you have to call for these to get service? Any checklist for ordering and also configuring for AT&T?FYI, we will do DHCP with it and it will be our backup ISP on and ASA if the primary internet goes down. We will just use a 172.30.x.x addressing between the ASA Outside-Backup interface and the 881G.

I am trying to confgure a L2L VPN tunnel to a service provider using an ASA 5505.My problem is that the service provider will not accept traffic from a LAN subnet, they will only accept traffice from a public IP.We have a small public subnet of x.x.x.50/255.255.255.248, our public IP (outside interface IP on the ASA 5505) is x.x.x.50 and the service provider wants to see traffic coming from us on x.x.x.51How can I NAT our LAN subnet (10.0.0.0/24) to one public IP (x.x.x.51)?

I'm trying to support a friend. They just switched to TWC Business Class from Megapath. They have a Cisco 5505 ASA and are trying to configure it to work with the new TimeWarner cable modem. But we can't get PCs behind the firewall out to the Internet.
We think it should be a pretty simple config. They have the ASA connected directly to the modem. The modem is running DHCP, and we''ve configured the ASA to get its address via DHCP. We have a Windows server behind the firewall; it can't get out the Internet either. It's set up to be a DHCP server and is giving IP addresses to the PCs on the network.
Laptops connected via wifi to a wireless router attached to the modem are able to connect to the internet, thus we know the modem is up and running fine.
Here's our running config:
ASA Version 8.4(1)!hostname ciscoasadomain-name opanslab.comenable password yYME2neTGgA0S1./ encryptedpasswd yYME2neTGgA0S1./ encryptednames!interface Vlan1nameif insidesecurity-level 100ip address

I have just changed my ISP and received a Thomson TG712 Modem, router and VoIP Gateway. Nice device, but I would like to extend my wi-fi network and connect a couple of PCs to another router in a different area using an almost new Linksys E4200 as a second router.I have already wired a network cable from the TG712 to the location where the E4200 is, tested the connection using a laptop, but cannot configure the E4200 to work receiving Internet service from the TG712.

I have a WRT100 wireless router, which is configured for a PPPOE connection to my ISP. After running one of the tools to determine responsiveness of DNS name services, I would like to manually configure my DNS services, placing a more responsive service as my first DNS choice. In the router administration, I can configure three static DNS IP's. However, I don't see any place in the configuration to turn off the automatic DNS configuration from my ISP. So, when I issue an IPCONFIG /ALL on my computer, the DNS listing shows two DNS Name Services from my ISP ahead of the three static DNS IP's that I configured.

Wireless service on Dell laptop computer had been running fine for 4.5 months until underground Comcast cable failed, presumably due to freezing and thawing in cold New England soil. All Comcast service went out, TV, Internet cable modem, etc. Service was restored with above ground cable, and wireless service returned to other devices in household, but not the Dell laptop. I am wondering if my wireless card itself was damaged in the event, as no software fixes I have tried have worked. However, the device manager says the Dell Wireless 1397 WLAN Mini-card is working properly and the driver software for the service is up to date.
Some of the messages I have received from various command line and dialogue box attempted fixes:
Dell Wireless 1515 Adapter Device Not Found
There are currently no wireless adapters available and enabled
Cannot repair adapter because wireless service is not running
Windows could not start the WLAN AutoConfig service on Local Computer
Error 0xc00 ce508 : 0x00 ce508
There might be a problem with one or more network adapters on this computer
When I did this
>Set Autoconfig Enabled=Yes Interface=”Wireless Network Adapter” <enter>
The response was this
>The Wireless Autoconfig Service (WLANSVC) is not running
When I was in administrator mode and ran SFC/SCANNOW the response was this Windows Resource Protection found corrupt files but was unable to fix some of them Details are included in the CBS.Log WindirLogsCBSCBS.Log For example C:WindowsLogsCBSCBS.Log Other command line responses:
Wireless LAN Adapter Wireless Network Connection:
Media State… Media disconnected
Tunnel adapter Local Area Connection* 6:
Media State… Media disconnected
Tunnel adapter Local Area Connection* 7:

I see not hits.I placed the rule on top of my access list to check if I do somethink wrong but it is not working. When I place only a service for example tcp/23 it is working.

We have a situation where services are stopped on the real servers. The probes fail and we confirm the services are not running on the server. We cannot access the ports from the ACE directly. We can still however acces the VIP on the TCP port (L4 VIP class-map). So we can still telnet to the VIP on the port from thr Client side of the network.This is on ACE 20 Modules deployed in Routed mode. The version of software is A2(3.3).
Tried removing multi-match and loadbalance policies as well as class-map and re-applying then re-appyling the service policy to interface. Same behavior,This is a problem at another level as some services are being monitored by GSS via TCP keep-Alive and this obviuosly causes a problem as the service then never goes off-line.

We are having issues transferring a 200GB VHD file across our point to point without being corrupted in the process. Any good application for testing the line quality across the point to point?Preferably we want something free, but if there is an in depth tool that costs money, we are open to that option as well.

I took my router with me to visit family at Christmas. It wouldn't allow the wired computer through the switch, but yet I could talk to the router with my laptop. Rather than reconfigure, I bundled up my router & laptop and let well enough alone.Now that they're all back at my house, I can't reliably get the laptop to connect - Low Wireless Signal error. I've reset the modem & router repeatedly. Tried Channels 1,6, 11 and 8&9 too. n only, as that's my laptop's. On 2 occasions it has connected, rebooted and auto connected and run for 4-5 hours. Then it's gone. I've beat this mess for 3-8 hours per day, for days...!!!Laptop(Vista) connects to every other wifi I've tried. It's sitting 4 ft from the router.
misc. info.
separate dsl modem, Centurytel, Netopia Cayman 3300 series
no other devices beyond wired desktop and laptop
no changes in other neighboring networks

How to export Air Quality reports from a 5508? I'm pretty sure I have read that we can not look back in time at the Air Quality report from the WLC, but can from NCS. If NCS was in the picture, can the Air Qaulity Report somehow be exported?

I'm in charge of the IT of a dorm with 200 inhabitants. A lot of people complain about the bad quality of "skype-calls". Audio is delayed and video stucks. The actual speed of our internet connection should be fast enough so I guess it has something to do with the QOS setting. I checked it on our WLC 3750 and right now we use Silver (best effort). Could there be any improvement when I set it to Platinum?

I have a client using a VOIP service to a third party provider (RingCentral). They are connected via Cable ISP (6mb) to the Internet and now experiencing performance issues with their VOIP service. They indicated that the call can be heard but that there is jitter and choppines in the call and they have to place a regular landline call. Their provider recommended using QOS to improve. I did not see anything straight forward on the ASDM interface to do this and figure it may require command line to accomplish.
They have Cisco IP 303 and 5252G2 phones which connect through an ASA5505 7.2(4) to their provider for service. Apparently the voip app uses the following ports:
UDP
5060-5090
8000-8200
16384-16482
What would be the best solution to improve performance or perhaps traffic shape / priortize traffic to work. I assume this may be happening if there are heavy downloads or activity happening on the network. The ASA5505 is on 7.2(4). Some coded examples for the above info.

I have a wireless router on the ground floor of my home which is wired to my PC on the 3rd floor. The wifi signal is of poor quality on the 3rd floor. I cannot move the router to a different floor since all of my connections are wired through the home into my networking room (on the ground floor where my router is). I wish to add a media receiver to a different room on the 3rd floor that is not wired already for networking. Streaming video files wirelessly to the media receiver from my router will not work because as stated previously the signal quality is poor on the 3rd floor. My mobo on my computer has ASUS wifi GO. Can I enable the wifi go on the mobo of my PC (located on 3rd floor) to connect to the media receiver (also on the 3rd floor) for streaming? The media receiver will also have an internet browser so will I be able to connect to the internet as well if it is networked to my PC and my PC is connected to my router on the ground floor?
I basically want to keep my PC connected to my main router for high DL speeds and also have my PC networked wirelessly to my media receiver using the on board wifi go. If possible I'd also like to be able to access the internet on the media receiver via the PC.

Had problems with voice quality on VoIP with 4500 series switches and the qos dbl feature (which gets enabled by the auto qos feature)?? I have had a couple of customer complaining about voice quality and our voice team spent a lot of time investigating; I had ruled out the network infrastructure because it was all QOS enabled. The voip people came up against a blank so I looked at the network once more and disbaled dbl with hope more than anything else. Mysteriously the voice quality issues the customer was having have now disappeared. Not sure whether a coincidence (though I have done this on two customers now) or something to with with dbl. There is nothing on this on cco.

We have a UC500 with 3 access points AP541N. We need to move around the building so we use wireless voice with 7925G phones. All works fine except when the phone needs to change from one AP to another. We lost connection for a small interval of time and then resume normal operation.
