  • Extreme x450e Voice config

    hello everyone

    Any of you guys have any experience setting up these extreme switch to work with a shoretel system, if so would you be generous enough to share you config and experience.. Also what is the purpose of the stacking cable. is it to make all the switches in the stack appear as one? i am not familiar with these switches so any advice will be helpful.

    thank in advance

    I will post some config information about routing when I have a little more time later on.
    Configuring Extreeeeeeme unk: switches is quite a bit simpler than Cisco :death: if you ask me, the commands are in english. (dave unpacks his flame proof suit)

    The stacking cable lets you connect multiple switches together into a single logical stack of switches. They behave as if they were blades in a chassis only rather than a chassis you have a dirty great big cable plugged in the back.

    To get you started here is how to create a couple of vlans, this doesnt show routing I will assume that routing happens somewhere else on the network:

    create vlan data
    create vlan voice


    (That wasn't difficult was it? :_smile

    Now we will assign a tag to them:

    config data tag 100
    config voice tag 101


    Next we need to give the voice vlan priority, Extreme has 8 QoS queues numbered 1 to 8 alot of other vendors go from 0 to 7 so watch out of that. on X series switches you have to create the QoS profile before you can use it.

    create qp7
    config voice qp7



    Now we will remove all the ports from the default vlan which is configured on the switch out of the box.

    config default del ports all

    Next we will add all the ports to the data vlan in such a way as we can connect a PC to the.

    Config data add ports 1-24 untagged

    If you have the switches in a stack, you refer to the ports slightliy differently. Each switch in the stack has a unit number and you need to specify the unit number when you configure a port by prefixing the port number with the unit number and a colon. So to configure port 15 on unit 2 you would refer to it a bit like this:

    Config voice add port 2:15

    Now we will add the voice vlan to all the ports so we can connect IP Phones.

    config voice add ports 1-24 tagged

    We will connect a DHCP server to port 1

    config voice del port 1

    We will connect a shoregear switch to port 2

    config data del port 2
    config voice del port 2
    config voice add port 2 untagged


    We will use ports 25 and 26 as uplink ports to the rest of the network:

    config voice add port 25-26 tagged
    config data add port 25-26 tagged


    Last of all:

    Save



    If I get a bit more time later on I will show you how to set up some basic routing so you can pass traffic between the vlans.

      re:

      i appreciate the quick response, this really helps out alot. if you get a chance that routing info would be great. could i achieve the same result as the stacking cable by using an uplink from one switch to the next. i know that they would not appear as one logical switch this way but what would be the benefit of using the stacking cable over using a patch cord to daisy chain the switches.

      thanks

        Just remember that if you are running to seperate V-LANs for voice and data, you need ports configured for just the voice V-LAN for your ST switches and the VM server. There is no way to tag the ST switches and server.

          OK, I am back off my install now.
          Lets add some IP addresses and routing to the config...

          config data ipaddress 192.168.100.1/24
          config voice ipaddress 192.168.101.1/24


          Now we need to configure the routing a bit, first we have to enable forwarding and tell the network where to find The Internet. Our internet router is on 192.168.100.254 in the data vlan.

          Enable IPforwarding
          config iproute add default 192.168.100.254


          Lets say we have another network (192.168.10.0/24) at another site and this is via a different router on 192.168.100.253

          config iproute add 192.168.10.0/24 192.168.100.253

          Unless we do something on the switch, we wont be able to get DHCP requests from the voice vlan to the DHCP server on the data vlan. DHCP server is on IP address 192.168.100.100 connected to switch port 1.

          config bootprelay add 192.168.100.100
          enable bootprelay


          Sometimes you will sit for hours wondering why your DHCP server appears to be giving out IP Addresses but the phones don't seem to be picking them up.
          Often this is because the DHCP server has been connected to a port that has been configured in multiple vlans like this:

          config data add port 1 untagged
          config voice add port 1 tagged

          you can give a command as follows which will list the ports that are configured in a vlan:

          show vlan data

          and you will get output which shows something like this amongst other things:

          Untagged
          1,2,3,4,5,6. .....
          Tagged
          25,26


          You would repeat the command but for the voice vlan:

          show vlan voice

          and see this:

          Untagged
          2
          Tagged
          1,3,4,5,6 .......


          Notice that port 1 is showing in the tagged section of the voice vlan.
          To make DHCP work correctly we need to remove port 1 from the voice vlan:

          config voice del port 1

          Next time we will set up port mirroring and configure the switch to have a nice latte ready for you when you arrive at work.

            Re:

            Okay

            i followed the direction to the letter and i cannot get the phone in the voice vlan to pull an ip address. i checked to make sure that the dhcp server port was not in the voice vlan and was only in the data vlan. any one have any suggestion as to where to look next.

              Web Access

              hello all

              also is there any web access to this switch, and if so what commands do i issue to set6 a management ip address to browse to it.

              Thanks in advance

                You can assign an IP address to the switch as if you were going to set the switch up for routing. I would suggest that you do this initially on the data vlan:

                config data ipaddress 192.168.100.1/24

                Once that is on there you should be able to use a browser to administer the switch provided your PC has an IP address in the same range as the switch (asuming you don't have routing set up yet)

                I can't remember if you have to also enable web access to the switch these days. If you do it will be a command like:

                Enable webmanagement

                (I don't have a command guide to hand)
                I suggest you type:

                enable [tab]

                which will give you a list of commands that can come next.
                You can find the command guide here:
                Extreme Networks
                You will be looking for XOS commands rather than extremeware on this type of switch.

                  Does the phone get an IP address in the data vlan OK?
                  Have you got the vlan=# parameter on your Option 156 setting on the DHCP server? (the # needs to match the vlan ID that was configured on the switch: config vlan voice tag 101 so vlanid=101 in this case)

                  I take it you have created a new DHCP scope on the DHCP server with the appropriate ip range for the voice vlan?

                  Also your DHCP server needs to be able to route packets to the voice subnet.
                  Test if you can ping your ShoreGear switches from the DHCP server.

                    yes i created a scope for the phones, but the funny thing is that if i do a display statistic on the new scope it show that and IP address is assigned but the phones never shows the ip address. I also went as far to set a reservation for a specific phone by the MAC and the DHCP server showed the reservation as active but the IP phone would not boot. that seems weird to me. A pc connected to the other port on the phone gets an IP form the data vlan.

                      Can you pm me the config on the switch?

                      Show config

                      And let me know which ports have the DHCP server and ShoreGear switches and HQ server attached.

                          Dave

                          the config has been modified slightly temporarily. as of now port port 2 has sg switch and dhcp on port 1, port 2 in data vlan and will have to be moved to voice only. everything is working in the data vlan currently and i set the qp7. i no some of the things need to be changed. see if anything else sticks out that might be causing issues. below is config from switch

                          Thanks
