• Implementation of VLAN / QoS for VOIP on RV180

  I posted earlier about setting up VLAN / QoS for VOIP on the SG200-18 (see: https://supportforums.cisco.com/discussion/12193666/setting-vlan-and-qos...).

  I did go ahead and buy the RV180. I connected to SG200-18.

  I wish to proceed with the implementation of VLAN / QoS on the RV180 so my phone (Grandstream VOIP wireless phone) VOIP is on its own VLAN separate from the rest of the network, so make sure that all QoS settings are optimized to give the first priority of VOIP network telephone.

  Currently I still have the VOIP phone connected to SG200-18 as stated in the previous post.

  Here are my questions:

  1 should I leave the VOIP phone connected to the SG200-18 and config all the VLANS, VLANS and VLAN Switch voice settings down to the VOIP phone, or should I plugged the phone VOIP in the RV180? Which would give me better performance and easier to do?

  2. How can I place the VOIP phone on its own VIRTUAL LAN, in addition to optimizing QoS settings so it gets a top priority for the network?

  3. I currently have set VOIP telephone in order to reserve a DHCP address in the 192.168.x range. When you move to the VLAN, should I set the DHCP reservation and/or my firewall settings (I through the firewall as well)

  4. I also get a beta-test VOIP Grandstream office phone. Time of its installation, what I have to plug directly into the RV180 or the SG200-18, and I have to put it on the same VLAN as the phone VOIP without wire Grandstream or VLAN different? It also supports PoE, but the RV180 or SG200-18 model I does not work. If I use an external power supply, connect each device will be OK or might that it became fried?

  Thank you!

  Hello

  1 should I leave the VOIP phone connected to the SG200-18 and config all the VLANS, VLANS and VLAN Switch voice settings down to the VOIP phone, or should I plugged the phone VOIP in the RV180? Which would give me better performance and easier to do?

  It will not be much difference between being on the switch or on the router, so it is for the most part to the simplicity of configuration performance.  If you plug the phone directly on the router, you will really not disturb trunking VLAN or none of this switch.

  This is really what is more convenient, but if you are able to plug into the RV directly I wouldn't worry QoS on the switch.

  So let's talk about implementation of the RV180.

  First go to network > LAN > belonging to a VLAN.  Enable VLANs, and add a new VLAN for voice (most people use 100 for voice for a reason, but it does not matter).  You will take care to set the port that the phone is plugged in not tagged to the new voice VLAN, and you can exclude the data VLAN of the port.

  Then go to several VIRTUAL local network subnets and configure the address range for it configuration DHCP / new subnet (for example 192.168.100.0) If you do not want to use it (makes things a bit easier)

  Finally, to enable QoS on the RV go to QoS > QoS WAN profiles.  Activate the WAN QoS, make sure that it is set to the priority mode and add a new entry to the table.  You can name it anything you want (I used VoiP), then set it high priority.

  Then go down on the link profile page and add a new entry here. Select the profile you just created in the drop-down menu, set the service to one, select traffic selector VLAN and make sure the drop-down menu for VLAN is the VoIP VLAN.

  At this point, we have a configuration where the voice traffic (or basically anything on the VLAN voice) will have priority when it comes out the WAN interface.

  3. I currently have set VOIP telephone in order to reserve a DHCP address in the 192.168.x range. When you move to the VLAN, should I set the DHCP reservation and/or my firewall settings (I through the firewall as well)

  The second VIRTUAL LAN should have a configuration of different subnet for him, because I spoke up.  During this process you will place the DHCP server for the new VLAN as well.  You can adjust your reservations for the phones, but it does not really matter what IP they get, since we are prioritizing voice any VLAN, so you don't have set up a reserve, unless you really want to.

  4. the Grandstream phone.

  I would put the Grandstream (and all the other VoIP phones that you could get) in the voice VLAN so that he would get the same priority treatment.  At this point with multiple devices, you can indeed install a trunk to the switch (VLAN normal unidentified and voice VLAN Tag) and configure the ports to the voice VLAN for these phones.  Who will ensure that the switch gives priority to the traffic of voice, even if it is probably not as important in their own country on the WAN.

  Regarding the PoE device connected to a non PoE switch or a router, there will be no problems.  I'm guessing that the phone also comes with an AC adapter.  It will not feed this power in the thread just because it's PoE, it's pretty much a one-way circuit.

  Hope that helps,

• Cisco QoS for VoIP 300

  I have a question about best practices for packages of priority voice on the LAN side.

  We have everything configured on the firewall/edge device for the prioritization of voice, however I'm not sure of the exact to take sideways steps LAN to make sure that the LAN traffic will not affect voice quality.

  A very basic configurations: vlan 1 (the default) for data and vlan 100 (voice) - the ports are configured as general (1untagged, 10tagged).

  At this point, the phones are manually set with a vlan, but form read these forums I see that I can accomplish this by creating LLDP and automatically assigned to him the vlan instead, manual setting

  My main concern, however, as mentioned above, is QoS.

  Does anyone have a good practice or advice on how to Setup QoS specially for the voice.

  I found this pdf file, but I didn't know where they came up with the EIF and CBS values.

  https://supportforums.Cisco.com/docs/doc-13461

  This is my first post on the forums; Thanks in advance for any help provided.

  Hi Thomas, this is done automatically through the QoS of Basic. Within a bunch of tag VLAN, it is a value of CFP (3 bits). When the switch receives such framework it will honor the value based on this value of CFP.

• SGE2000p QoS for VoIP

  I am trying to increase our quality of telephone problems. Things like backup tapes, download heavy etc. are originally phones get all cracked. I don't know where to start. Everyone says of VLANS, but I don't know if this is the best choice. I don't know anything about QoS in the SGE2000P switches. I keep reading, but he gets no more clear. I need a little help direction. I see things on the VLAN, basic QoS, QoS advanced and do not know which route to go.

  I have 3 batteries of the total of 8 switches switches network segment all the same SGE2000P. The main chimney is connected to smaller piles by a fibre optic cable. Some computers are connected to the voip phones due to the absence of inside wiring of the building, but a lot of phones have a line dedicated to the switches.

  Consider phones like three switches of ports (because that's what they are).  A port is the phone, going to a single port and a port goes to a PC.  A switch when you set a port as a trunk you can tag the traffic for VLANs, create separate virtual local networks on a single physical link.  Similarly, on the side of the phone when you configure an IP to use phone a VLAN you say the switch to have a trunk port to your switch and the telephone to communicate on this VLAN tagged.

  The VLAN native is the VLAN untagged.  Computers don't understand VLAN and just send the traffic untagged so when you connect the PC to the back of the phone it will operate the same as it does now.  the difference will be that the phone will be on a different subnet and VLAN.

  Taking example of VLAN 100 for voice, you need to change the IP address of your IP PBX for something in a new subnet as 192.168.100.1/24 and create a port on a switch, a put in VLAN 100.  Connect to your firewall for routing inter - vlan.  Then find a way to get the phones IP address in the subnet and configs updated to use VLAN 100 and enter 192.168.100.1.  If you configure inter - vlan routing properly advance, you should be able to have a reboot of the phone, coming up on the data VLAN, get a new configuration that specifies the use of VLAN 100, reset again and this time come on VLAN 100 with the new address and function properly.

• Implementation of VLAN and QoS for VOIP on SG200-18

  We recently purchased the smart switch SG200-18 to replace a Netgear switch. We are moving our phone service to VOIP through our local ISP as well.

  I currently have the VOIP phone plugged into Port 17 on SG200-18 (it is a Grandstream Cordless VOIP phone).

  I want to put the VOIP phone on one VLAN separate from the rest of the network and optimize QoS parameters so that the VOIP phone has exceptional audio quality even during network traffic.

  Here are my questions:

  1. do I need to set anything on the type of port to Port 17 (because it resembles a shape any Combo port)?

  2. How can I do to isolate VOIP telephone it's own VLAN (I see the parameters VLANS and VLAN voice, not sure that one to use;) I've tried to set a VLAN and broke the Internet connectivity on the phone until I went and removed)?

  3. do I need to adjust the QoS settings to switch to better optimize the VOIP phone?

  Some additional questions about the GS200-18 in general:

  1. do I need to adjust the parameters of the system on the switch time? I am in the Central time.

  2. do I need to adjust the Green Ethernet/Energy Saving parameters or should I stay with the default settings?

  In addition, a couple of "getting started" questions for Cisco:

  1. I registered an account My Cisco. What should I do to register my switch with Cisco and associate with my My Cisco account?

  2. What are the benefits of purchasing a contract of Cisco Small Business support, and how much would it cost the SG200-18 (I ordered it from Provantage)? I'm curious to see if it's worth the money.

  Here's my 'features ':

  Switch: SG200-18

  VOIP phone: Grandstream DP715 and 710 handsets

  Plugged in: Port 17 on SG200-18

  Services: Internet Local (Direclynx)

  Type of connection: 3 m down / 500 k up DSL move to a future wireless connection that will give us higher speeds

  Backend VOIP provider: VOIP Innovations

  Router: Apple Airport Extreme AC model (all Macs and iOS devices and the OS X Server on the network, so I use the Apple router facilitates installation, because is not QoS, trying to QoS and VLAN in the switch)

  Thank you all!

  Hello

  I'll just go to the list again:

  1. sounds good in the port from the drop-down list. So can I just connect the VOIP phone and go with it, correct?

  Yes, just plug in ethernet combo port and it will work.

  2. is not an issue, but I agree, Apple likely isn't compatible QoS or VLAN.

  3. thanks for the info on time/NTP settings. If I wanted to go there and try to configure NTP, how much is it and what I have to do? I want to I can give it a quick try.

  To Setup NTP on the switch is quite simple.  Go to Administration > Time Settings > time system and check the boxes to activate the main clock Source (SNTP)

  Then go to the settings of the SNTP page and add a new entry with the IP address of an NTP server.  There is a list of available NTP servers here:

  http://www.pool.ntp.org/en/

  You must also ensure that the switches Administrative default gateway is set correctly (it must be set the to the default gateway, probably the most convenient airport) so the switch can contact the NTP server.  That option is set under Administration > Interface Management > Interface IPv4.  Change the user-defined default gateway and enter the IP address of your airport (or whatever your default gateway for your network)

  4 sounds good on the Green Ethernet settings. I'll leave it as default value.

  Yes, better to just let those unless you have weird problems with ports disconnect, who can sometimes be caused by Green Ethernet, but if there's nothing like leave it on and save a few watts.

  5 sounds good on does not need to attach my passage to my Cisco account. Should I fill out a form any registration of the product with Cisco before calling support?

  It is not a record for support.  The only thing we need you to do is to create a Cisco account, but you have already done this, so if/when you call in support, you just need your ID for Cisco (also called a CCOID sometimes) and the serial number of your switch.

  6. thanks for the info on the Service contract. Is it something that I would need to order directly from Cisco or I who would get my Cisco partner (Provantage)? After the three years is up, treat yourself to renewal or it just falls? Is there a certain amount of time I have to buy the Service Contract forward make me ineligible?

  Support contracts are purchased through a partner Cisco, or you can get them online for the CDW or Newegg for example.  Basically, you have until the expiry of your current aid for the purchase of a new contract.  For example, right now your switch comes with 1 year of technical support.  You can only buy a contract while it is still active.  Once your three-year contract is about to run out, you're in the same situation.  You can renew it before it expires, however if you leave is up, you will not be able to put a contract on it.  Contracts are not my specialty, however, so you can check with your partner for complete details.

  7. sounds good to how data use VOIP calls. His dislikes too. :-)

  I agree, a voice call is not much traffic.  What you have described you probably don't have problems, although of course I can't guarantee that.

  8. because it is from your provider and they specifically mentioned the VOIP, I would say that you'll be fine here.

  You had also placed on your airport using access point behind a router in small businesses.  I would like to say that it is possible, a large number of wireless routers have an option to put access point only mode or something like that, but you should check with Apple on how to do it.

  Insofar as a Small Business router if you decide to upgrade for the options VLAN or QoS, I would recommend the RV180, or perhaps the RV320.  Two of these models are available with or without wire depending on what you decide to do with the airport.

  I think I got all the questions, but if not just let me know,

• VoIP QoS for Tunnel from Site to Site

  Hi all

  I need help to configure QoS for VoIP between two Cisco ASA 5505 with VPN Site to Site.

  There is no need for bandwidth reservation, only 46 (EF) DSCP should be higher and DSCP 26 second queue higher and rules apply only to a site to site VPN.

  Usually, I try to configure the ASAs via ASDM and discovered in the documentation Cisco how configure QoS DSCP bits with a Service policy and how to configure QoS for a VPN from Site to Site (rule Service-> Match traffic strategy). But how to configure QoS for a bit DSCP applies to Tunnel from Site to Site? And how configure different priorities for both DSCP bits, this is defined by the order of political Service?

  The quality of service must be activated on the two ASAs to inside interface?

  Thanks in advance

• Setup of QoS for Whatsapp and VOIP application

  Hello guys,.

  I have a modem WAG320N. I have wasnted to configure the QoS priority for 2 applications 'Whatsapp' and a VOIP application that allows me to call from a computer to a mobile phone. I use torrent applications and that they take all the bandwidth. That's why I was looking for to configure QoS for these two applications.

   

  I went to the page of QoS and they are wondering about the details of the application as the range of ports etc.. I don't know what value to be filled. I posted a screenshot below of his request. Can someone help me fill out these details for both applications.

  Thanks in advance

  Image: http://i40.tinypic.com/2qi02z5.jpg

  You can add essentially Viber on QoS. Under the games and Applications, QoS, click on enable priority access Internet. On the category, find the Applications > add a new Application. You can enter the name of the Application. You can now add the port numbers. And since it is a specific port and no beach, do you this way;

  5242 - 5242 TCP (for Protocol)
  4244 4244 TCP
  5243 5243 UDP
  9785 9785 UDP

  I hope this helps.

• QoS for tenant

  I rent a small apartment next to my house.  The tenant use the internet a lot and when I try to use it, it becomes very slow. I don't want to limit bandwidth, when I'm not home that he can use all he wants, but I want a way to give priority to my use of the internet.  My main router is a 1841 and I have already setup QoS for voice.  I just want to apply the QoS policy on his particular IP.  I give him a public IP address and it connects his router.

  So, basically, I want to have him use internet at full speed, until I decide to use it, at that time my stuff will prevail on his stuff.  It will always be unless it is VoIP, then VoIP stuff will always take precedence over everything.

  The 1841 has two interfaces Fa0/0 is my WAN and fa/0/1 my LAN.

  How can I do this?

  Bandwidth control is what is used to establish the value of percentage Yes.

  Queues of traffic is only really makes sense when you let the router not load Rx is already received over your WAN interface.i.e. entry.

  Then apply the policy to output interfaces (output) and that should do the job.

• Implementation of QOS for on multiple switches for two VLAN

  afternoon all that I was looking for a little help in configuring QOS for two local area networks VIRTUAL, I created. These will be for voice traffic vlan 22 and traffic video vlan23. I also have three other VLAN for pc, wireless devices and our cnc machines. We have 5 switches which are all SG30028P with a single switch making the intervlan routing (Layer 3-powered). all switches are resources shared by the main switch and ive been through the guide written on how to do it on a single switch, which I think is layer 3.

  could someone help me with what I want the video and voice to take precedence over the rest of the traffic

  best regards Patrick

  Right, this way, you can give priority to IP or MAC address.

  No, there is nothing different, only one review of the routing. As the L3 switch can make local routing decisions, the placement of the ACL can vary. In an L2 environment, all packages are transferred to the router, then back down the network to the local destination, so you can clear an ACL on the uplink.

  Since you have a L3 switch, you can practice the same, empty an ACL on the link downstream for L2 switches for all traffic subject to the ACL. Any connection to the L3 switch, you can of course apply an ACL to the uplink router to get all notice of incoming traffic correctly. You can also apply a policy on port source interface to get the note as soon as traffic hits the switch.

  QoS policy is the concept of an ACL, you want it is the closest to the resource. If you apply a QoS policy an uplink upward, QoS will be marked up when it hits this port. Not before. So it should be applied closest to the device as possible. Many times, local QoS is not as important, until it starts to get to the router. As most Cat 6 environments can generally manage all local traffic. So, depending on the number of devices and the amount of traffic, a decently robust network can handle all traffic local then you just give priority to the uplink remarks to ensure that what is important is first.

  I have infrastructure cisco catalyst cisco 2960, 3560 and 2 x 4.2 ACS and authentication of 802. 1 x is working very well.

  I tried to add Linksys SRW2016 in rail infrastructure, but I encountered a problem.

  I did the same configuration on ACS for all other switches and I configured SRW2016 according to maunal for .1x and log on to ACS in FAILURE ATTEMPTS I got following error:

  Message Type: bad NAS request

  Authentic-failure-Code: authenticator of invalid message in the request of the EAP

  I have receked configuration especially the Shared Secret, and that's OK.

  No idea what is the problem and how to solve?

  Best regards

  Goran,

  It is especially indicative of a bad shared secret. Can you confirm if the Linksys switch is in a NDG, and if so, you have keys defined for the NDG?
