Help config vlan and inter routing vlan on 2 switches SF300-24 ???

Dear Cisco!
now we have 2 switches: SF300-24
on one SF300-24 we config it at layer 3 mode with VLAN configuration same as following
VLAN ID 2 (ports: 2 -6) have ip interface  192.168.2.254/24
VLAN ID 3 (ports: 7 - 10) have ip interface  192.168.3.254/24
VLAN ID 4 (ports 11- 15 ) have ip interface  192.168.4.254/24
and VLAN 1 default have IP address: 192.168.1.200
DHCP relay  - DHCP server 192.168.3.1
                   - DHCP relay: VLAN2; VLAN3; VLAN4
ip route: 0.0.0.0   0.0.0.0  192.168.3.1
all ports of VLAN2, VLAN3, VLAN4 set access mode.
and another SF300-24
was configed at layer 2. We config VLAN ID 2 ̣̣̣have ports  2 -6; VLAN ID 3 ports 7 -10; VLAN ID 4 port 11-15 ,too.
And we use port 26 on 2 switches SF300-24 is trunk mode then we connect both SF300-24 switches.
But on SF300-24 layer 2 cann't inderstand VLAN from Sf300-24 layer 3!!!
Could you please help me check this situation?
How to config VLAN on 2 switches SF300-24 Layer 3 and SF300-24 layer 2?
Thanks!
See you soon!

Son Nquyen,
First i would upgrade to 1.1.8 since the 1.0.0.27 was beta code.
Next when when connecting both switches together each port will need set via Trunk mode with proper native vlan and tagged vlan traffic. What's the configuration of your trunk ports on each switch?
Thanks,
Jasbryan.

  • Help config vlan and inter routing vlan on SF-300

    Hello All.
    I have divided the problem in Routing "SF-300 (Layer 3) can be connected to the Gateway." I did not want to put the Gateway. Injury I ever met with Packet Tracer 5. Can I attach a file. Leave all to me.

    Hi Suwatchai, I'm not sure what you are asking.
    On my first post, there are 2 different IP subnet. How I understand you, you would like the computer 1 on FA1 to talk to computer 2 on FA6 which are 2 different subnet. Using your example config on the original post, the computers should have an IP configuation such as stated
    Computer on fa1.
    IP 192.168.10.100
    Gateway 255.255.255.0
    Mask 192.168.10.1
    Computer on Fa6
    IP 192.168.20.100
    Gateway 192.168.20.1
    Mask 255.255.255.0
    These IP addresses do not have to be your selection. They only have to be in the proper subnet with the correct gateway address. The gateway and subnet mask are not negotiable, the IP address is. Assuming the NIC on each computer is configured correctly based off that switch config output, this should work without any issue. If it fails to work, it is most likely an external factor as to why.

  • Adding VLAN to Po-Group and OSPF routing what is the correct way?

    Hi Community,
    I recently had an issue that brought down the links between a couple of switches...luckily this was done after hours and I did not save the config so was able to revert back.
    The basic scope of my project is:
    We are running out of IP's on the 192.168.1.0/24 sunbnet so wanted to create a seperate VLAN/Subnet  for physical workstations.
    He is what I orginally did;
    1) On our core switch; (Switch1) 
         Create the VLAN,
         VLAN interface,
         DHCP pool,
         excluded address'
    2) On second  switch (Switch 2)
         Add VLAN name, no interface
    3) I then updated the PO-group on Switch1 with new VLAN  (this brought down the link before I was able to finish my config)
        Therefore I was not able to complete the following:
              add vlan to spanning-tree or updated OSPF routing
    Here is what I assume to be the correct order?
    1) On Core Switch (Switch 1)
         Create VLAN
         VLAN interface
         DHCP pool
         excluded address'
         add vlan to spanning-tree
         add vlan (passive interface) and sunbet to OSPF routing
    2) On Switch 2
         Add vlan name/interfaces with no ip
    3) Update PO groups after the above has been configured
         Add new VLAN to Po-Group on Switch 2
         Add new VLAN to Po-Group on Switch 1
    4) Last steps
         Updated specific access ports with new VLAN and test
         upon completion of testing, update all other access ports connected ot workstations with new VLAN
    Questions:
    Did my links go down because I added new VLAN to Po-group BEFORE  updating spanning-tree and OSPF routing?
    Can anyone verify the order as outlined in the section "Here is what I assume to be the correct order"

    So the order in which to apply TASKS is correct?

    What configuration do I need to work properly?
    Please help me. This urgent.
    Thanks.

    Unlike a Router, an ASA appliance will try and NAT traffic going from one internal subnet to another.
    You need to add a static NAT per subnet, as below:
    static (inside,PHONE) 192.168.1.0 192.168.1.0 netmask 255.255.255.0
    static (PHONE,inside) 192.168.10.0 192.168.10.0 netmask 255.255.255.0

  • RV320 loosing WAN and inter VLAN connectivity

    I just received a new RV320 V01 router and I am having trouble with the router loosing WAN and inter VLAN connectivity. Anywhere from 2 to 24+ hours the router will stop routing traffic to/from the WAN and other VLANs on the network. I have a ping trace running on one system and all packets are lost when the routing fails to all WAN connections and systems on other VLANs. I am still able to ping all of the router address for the VLANs i.e. 192.168.1.1, 192.168.2.1, 192.168.3.1 etc. Unfortunately I only have one system on this VLAN so I do not know if I can ping other systems on the same VLAN. I also do not have any DNS resolution when the issue occurs.
    The router is set up using a single ISP connection on WAN1 using DHCP assignment. WAN2 is disabled in the router settings. The router has version v1.1.1.06 firmware. I have also tried disabling VPN pass-through as noted from other posts. When the issue occurs the WAN1 connection is showing as “Connected (Inactive)” with no assigned IP address, gateway or DNS servers. The router is in gateway mode and everything works fine until the problem.
    Any Ideas?

    You noted that the WAN 1 connection has no IP address when this occurs.
    When it occurred last, I noted the "Connected (Inactive)" on WAN1 and that there were no IP addresses assigned.  I have a screen shot of the page attached.  I had noticed the "Connected (Inactive)" previously when the problem was occurring but cannot definitely say there were no IP addresses at that time.  I do not recall if I noticed this before or after I had disconnected the WAN1 to test a direct PC to modem connection.  I did check with the cable company and there are no issues being noted or logged on my connection.  The direct PC to modem connection worked fine.
    What type of Internet connection is it? (Cable, DSL, T1, etc)
    The connection is Cable
    Is the WAN port configured for DHCP?
    The WAN port is configured for DHCP
    Who is the ISP?
    The ISP is the local cable company
    When the issue occurs, can devices within a subnet ping each other?
    As I noted in the original post, at the time I was on a VLAN that only had one system running to monitor ping traces.  I will try again next time the problem occurs to have multiple devices on the same network.
    Are there any switches in the network?
    Yes, there is a switch in the system.  I am using a cisco SG200-26.  However, the problem persists even when I directly connected a PC to the active LAN port on the router.  No issue when the PC was dirrectly connected to the modem.
    Can you draw a simple topology showing the network with IP addresses, VLANs, etc?

    Hi Jarey,
    Are you sure you want to do this on the switch as opposed to the router? Are you going to use static IP addresses for the vlans or do you want your router to issue DHCP?
    To proceed, using the switch for inter-vlan routing, make sure the SG300 is in layer 3 mode.
    1. If you are currently in layer 2 mode, open a CLI connection and issue command:
    set system mode router
    Take note that this will delete your current config and the switch will reboot.
    2.  Create the vlans on your switch under VLAN Management -> create vlan
    3. Go to IP Configuration -> ipv4 interface and assign each vlan a static IP for the switch in the subnet for the new vlan
    4. Vlan Management -> Interface settings. I would leave all the ports as trunk ports, or change the ports to trunk if you have previously changed them.
    5. Vlan Management -> Port VLAN membership. Assign your vlans to the appropriate ports.
    6. When everything is all plugged in, you should be able to see the switch created static routes for you already under IP Configuration -> IPV4 static routes. Make sure all your subnets are there and are showing route type local
    7. You may need to add a route such as 0.0.0.0 with the next hop being your router
    At this point, you should be up and running, with all vlans connected to each other and to the internet.
    If you want to restrict access across the vlans, you'll have to create access control lists.
    You need to first create an ACL (Access control -> IPV4 based ACL) and give it a name. then go over to IPV4 based ACE where you put the actual access control rules.
    This is a sample set of rules I made, it will block all access between two subnets (each vlan you created above will have to be its own subnet) and allow certain traffic such as 3389 - remote desktop, etc. You'll need to customize based upon your needs and subnet IPs. So for ex, to allow the Xboxes to access the file server, rather than any - any, you put the xbox subnet or specific IPs as the source, the file server as the destination, and the ports used as source ports. Remember to make the converse of the rule as well.
    Then, go to Access Control -> ACL bindings and bind the access control list to the applicable ports.
    Hope that helps, good luck with your set up.
    Best,
    David

  • VLAN trunk from switch to router

    We have a 2691 cisco router and a Linksys (cisco) 24 port switch.
    Each E port is set with a different untagged VLAN ID grouped to G1 uplink port and is tagged
    The G1 port then is trunked and is tagged to native VLan 1
    One of the router ethernet ports is configued as
    interface FastEthernet0/0
    description $ETH-LAN$
    no ip address
    ip flow ingress
    duplex auto
    speed auto
    no cdp enable
    interface FastEthernet0/0.1
    description $ETH-LAN$
    encapsulation dot1Q 1 native
    ip address 216.110.213.1 255.255.255.0
    ip flow ingress
    no snmp trap link-status
    no cdp enable
    Is this correct ?
    Problem is all VLAN E ports on switch cannot get past the router.
    Some E ports not with VLAN then default to VLAN 1 and they can function past the router.
    The config of the switch was verified with Linksys as being correct which leaves a router config issue
    So in short the switch would have 24 VLANs untagged going through trunk which is tagged ending up hitting router and then out WAN ports.
    Thanks for any help for cisco and linksys have been no help solving why servers on switch with vlan cannot see past router
    JR

    Is this correct ?
    A: The configuration above says that vlan 1 is native vlan, which means the router is expecting a "raw" packet to belong to vlan 1. "raw" packet menas it does not have any vlan id, I do not want to use "tag" coz "tag" might mean something else to Linksys. So, if it's "raw" as in if a PC transmit a packet, it will have no vlan id field.
    Problem is all VLAN E ports on switch cannot get past the router.
    Some E ports not with VLAN then default to VLAN 1 and they can function past the router.
    A: If you mean, they can ping the 216.110.213.1 and beyond 216.110.213.0/24 then that would be expected.
    The ports that belongs to other vlans will need a default gateway of their own, they cannot use the vlan 1 gateway because they are in different subnet. from the cofnig above, you only have sub-interface for vlan 1, do you have sub-interface for other vlans? If not, you need it.
    The config of the switch was verified with Linksys as being correct which leaves a router config issue
    So in short the switch would have 24 VLANs untagged going through trunk which is tagged ending up hitting router and then out WAN ports.
    >> This goes back to above, native vlan on cisco router will be the only vlan the router will expect with no vlan id, otherwise, everything the router rx with no vlan id or dot1q encapsulation will be assumed that it belongs to vlan 1. do you have other sub-interfaces on the 2691 for the other 24 vlans?

  • CSM4.4 and 87x router interface config

    I'm trying to configure a bunch of 877 routers via CSM4.4sp2. I'm struggling with assigning the ports to VLANs.
    On the 87x router there are 4 switch ports, which are handled rather like a L2 (eg, Cat2960) switch in that you can't assign them a L3 address as you would a regular router port. Rather you create an SVI (int vlan 200) and assign the port to that VLAN (switchport access vlan 200).
    I can create the SVI from CSM under the Interfaces policy, but I can't for the life of me see how to assign the switchports without having to do a FlexConfig.
    I imagine the situation will be the same for branch routers with eg HWIC-4ESW switch modules.
    Anyone?

  • How to route two vlans on two switches that are connected only on one router?

    Suppose that any of the trunk links fails or if you want, suppose that there is no link between SW1 (G0/1) and SW2 (G0/1). How can you make computers in Vlan 10 to see computers in Vlan 20 and viceversa?. I tried creating a bridge group on the router for G0/0.10-G1/0.10 and another for G0/0.20-G1/0.20. Then define interface BVI10 and BVI20. Interfaces came up but you can not configure dot1q on them and switches can not see them. Anyways with one interface on the bridge group going down the BVI interface goes down as well so that's not an option. Router should be 10.10.10.1 and 20.20.20.1 and each computer have that as gateway respectively.

    Jody thanks very much!
    Indeed the encapsulation was done in the sub-interfaces, as posted in the OP you can not [encap dot1q X] on the BVI interface. Even though, the switches didn't established the trunk with the BVI. Anyways using bridge groups is not an acceptable solution because with the failure of any interface of the trunk links in the router, the BVI interface goes down as well.
    You said "if I want to handle it at layer 2" How will you do it at layer 3? I though something like HSRP or VRRP but that doesn't apply since it is only one router. Remember, the router must be able to route between vlan10 and vlan20 for computers on both switches in case of one of the trunk link failure.
    This is for learning purposes so I started with Packet Tracer but PT doesn't support bridge groups. Then I tried GNS3. I will try with the router in GNS3 with a switch module but I'm not clear. that will be like having a 3rd switch, right?  What I mean is that I will not be using routed interfaces between the router and the switches, right?

  • What is the proper config for the Airport Extreme when a Voice over IP device is between the cable modem and the router.

    What is the proper config for the Airport Extreme when a Voice over IP device is between the cable modem and the router.  Its a VoIPo device. The cable modem is connected to the VoIP WAN port and the LAN port on the device feeds the Airport Extreme.  The VOIP is working fine, and my Mac are getting 10. addresses from the Airport Extreme.  But I do get confict messages and lose my connection periodicaly.  Looking for help.

    Its a VoIPo device.
    Per chance, is this device the Grandstream HT502?

  • When my 4S connects to my home wifi, it kicks all other devices off and the router has to be restarted.  Can anyone help?

    I am using an iPhone 4S with 16gb memory.  I did not yet update to iOS 8.  I'm using 7.1.2.  I have never had any problems previously using 3G or wifi.  We just moved and have a new Netgear router supplied by our new ISP.  We have ADSL connection.  The router seems to be working fine for all the devices in the house.  At any time we may have 2 or 3 laptops connected, as well as Kindle Fires, iPod Touches, and my husband's iPhone (which is the same make, model, year as mine).  My iPhone will connect, but usually within minutes after connecting my iPhone 4S (though sometimes 30 minutes or more later), it kicks everyone offline and the router needs to be restarted.  The router shows appropriate green lights and I can see it on my list of available networks, but if I try to connect I get the "unable to connect to this network" message until we restart the router.  No one else is able to reconnect until the restart, either.
    I have tried resetting network settings on my iPhone.  I have completely turned off my iPhone and the router.  I have talked with someone at our ISP and they did a reset of the router with me.  They think the router is bad.  But it works completely fine for everyone else in the house, so I can't help but think we are having a connection issue between the router and my iPhone.
    Any help you can offer would be greatly appreciated!  Thank you!

    Is her iPhone in a case by any chance?  If so, remove the case and try again.  How does her iPhone work in free Wi-Fi locations?
    Try resetting the iPhone...
    Press and hold the Home and On/Off buttons simultaneously until you see the Apple logo, then release.  This may take up to 10 seconds.  This is the equivalent of a re-boot and you will not lose any data.
    If none of the above work take it to an Apple store or AASP for evaluation.  She will not be charged folr this and they will suggest a solution if there is a fault.

  • Spanning vlans across access switches in distribution block.... please help

    Hi All
    Can someone please explain why Cisco states that in a Campus Hierarchical modle if Vlans are spanned across Access switches in a distribution block, then the Distrubution to distribution link should be Layer 2. Is this really necesary or just a recommendation, and if so why? Can't this link be a L3 link when spanning vlans across Access switches in distribution block, as I understand the benefit of having a L3 distribution to distribution link so that SPT is avoided.
    Please help

    Hello,
    The cisco recommended design is L3 links, but these is only possible if you have no vlans you need to span over the hole network.
    It depends on your topology or what you want achieve.
    If you need for one or more vlan's spanned the LAN, you need to use a layer 2 connection between all switches and between distribution too.
    In my company we have for example a few vlans for restricted areas, like device management or else, so we can't use L3 Links in the distribution area because these vlan's are terminated at the firewall. I think these is good thing.
    I would recommend you if you don't have to span one or more vlan's across the network to use L3 Links, specially in the case of redundancy way's. So you need no spanning-tree, but need to use other protocols like GLBP or else. The works faster and are not so confusing (for some people) as STP.
    best regards,
    Sebastian

  • HT4839 PLEASE HELP!!!  I am simply trying to update the APN settings on my Iphone3 AT&T carried Straight Talk SIM phone.  For some reason, when I enter the Straight Talk APN info in the Config Utility and click "Install", NOTHING HAPPENS.  WHY?

    PLEASE HELP!!!  I am simply trying to update the APN settings on my Iphone3 AT&T carried Straight Talk SIM phone.  For some reason, when I enter the Straight Talk APN info in the Config Utility and click "Install", NOTHING HAPPENS.  WHY?  I have spent almost 2 full days simply trying to get the cellular data network settings to appear and I am now at the point of pulling hair and/or smashing things.  Why is it so difficult to simply update the cellular data network APN settings on a standard Iphone 3 ATT with a unlimited Straight Talk plan?  Everyone knows that Straight Talk's $45 a month unlimited data/calling plan is supposed to be 100% compatible with AT&T carried Iphones.  Will someone please tell me HOW TO UPDATE THE APN SETTINGS ON THIS IPHONE 3.  Thanks and God bless

    StraightTalk is not a supported carrier.
    Contact them for support.
    FYI, unless the device is officially unlocked from AT&T, you will not be able to use it on another carrier.

  • Help I have a  BEFW11S4 router and my labtop wont connect...

    My desk top is connected.
    How to I connect my laptop? any suggestions.
    they usually send you to the 192.168.1.1 or something similar. I forget how to ping also so I couldn't check that.

    I changed the channels mine was set on 6 when I went into setup. My internet connection is set to PPPoE   It didnt say anything that said " beacon interval" or "RTS and Fragmentation threshold"  where would I find that at??
    Anyway my wireless computer can connect online with excellent strength but my desktop will not connect. I disconnected the router and pluged the computer into the modemn and I had internet access although my signal was not great. All my lights are solid.
    Should I bite the bullet and just go get a new router??
