Route ip SF300

• Routing problem mode SF300 - 24 Layer 3

  Hi all, as a topic, I have a problem with my itinerary SF300-24. This is my network configuration:

  Port 1 to 12 assigned to VLAN 10

  Port 13-23 assigned to VLAN 20

  24 port has an IP 10.17.7.254 to connect with my itinerary deafult, because I also have a Linksys RV042 router, connected in turn with my ISP router, having a 10.17.7.1 ip address.

  VLAN 10 has 10.17.10.1

  VLAN 20 was 10.17.20.1

  So I add a default route on my SF300-24 to 10.17.7.1 to get an Internet connection.

  Here's the problem:

  Computer A is connected to VLAN 10 on port 1

  Compuer B is connected to the VLAN 20 13 IDE oucederomsurlesecondport

  An e B can talk perfectly each other and also to port 24 (10.17.7.254), but when I try to ping my Linksys RV042 (10.17.7.1) or reach Internet all fail.

  Instead when I logged in SF300-24 and try to ping Linksys RV042 (10.17.7.1) or Internet access, everything works great!

  What could be the problem?

  Thank you

• Spend several layers (Layer-3) routing!

  Hello community, I need help in this topology.

  the topology of the network.

  my intention is to catch the subnets communicate to reach the server, also, I would say to activate the dhcp relay to receive the ip address of the server that is in the swcore.

  Doubts;

  -Where I put the IP addresses of interfaces? SW-core or sw-DIS? or both?

  -What are the steps to make this purpose to work?

  -I could not activate a tree covering weight in this sw model.

  Thank you very much

  Hi Elisamotta,

  Is this requirement you are going to design and implement from scratch.

  States of recommendation of normal design with legacy architecture must have three tier architecture with seen fast routing process, Distribution based political switching and access with end layer calculate basic connectivity.

  So with devices of distribution best practices should be seen SVI all and routing connectivity with the layer of base to the outside world.

  Hope that helps...

• Vs SF300-24 L2 L3 Modes

  24 / SF300, what is the major difference between L2 and L3 Modes.

  The switch, to which you refer is both layer 2 and layer 3 active. If it is enabled, this means that the switch can perform

  functions at the level of the selected layer. An active layer 3 switch essentially acts as a router, while the

  an active layer 2 switch does not work. Layer 2 switches receive packets and transfer them to the correct in location

  a network. Layer 3 switches and routers both do the same thing, but use IP addresses in the packets forwards, between or within networks.

  See the next page for more information on the subject:

  http://www.Cisco.com/Web/about/ac123/ac147/archived_issues/ipj_1-2/switch_evolution.html

  If you have any other questions, I'll be happy to help you.

• Linking the two switches SF300-8 and gvrp

  After passing the age trying to propagate VLAN one SF300 to another, I think that I finally did it.  It seems that we must implement the GVRP Protocol on both sides of the trunk AND manually create the VLAN on the slave switch.  Now I can ping machines on the two switches that share the same VLAN successfully.

  However; If I try and ping a machine on the passage of the slave from outside in the VLAN, which is a connection routed the master switch, it fails, succeeds the ping of a machine on the main switch.

  What I am doing wrong?

  Hi Nigel, GVRP is basically a terrible (and useless) Protocol.

  GVRP not to dispose of anything, unless it is predefined to what it can affect, the manually fresh General requirements is greater than the configuration comes actually port.

  Configuring you mentioned basically tells me that you built manually the trunk as vlan 1 UNTAG, tag 11 and 42. The GVRP Protocol should do it for you if it is properly implemented.

  To work successfully the port GVRP must send the GVRP join messages, the interface of the receiver must be configured to receive the join messages and then the database of VLAN switch advertising must have these VLANS constructed/defined manually as they are underway in the messages...

  If you need using the configuration, do not hesitate to post what is your goal, I'm sure I or someone can help you if you provide a network, the schema and configuration files.

• Need help with configuration of VLAN SF300-24

  Hello

  Let me Preface this with the fact that networking is certainly not my point hard, so here, any help is greatly appreciated.

  I'm trying to segment on a virtual desktop on its own VIRTUAL local network infrastructure using a Cisco SF300-24 Layer 3 switch. I can get the switch to connect to the network with the assigned VLAN 1 an IP address on the subnet of the network (192.168.16.X), but I can't get anything this is set up VLAN 20 (192.168.20.X subnet) to connect past the VLAN 20 (192.168.20.254) gateway IP. The ports assigned to 20 VLAN are defined to access the mode if it matters.

  Here is a diagram to illustrate what it looks like, as there is another (L2) switch involved.

  

  So I'm not really sure what I am missing here since all settings seem simple enough.

  Hi Simon, I recommend you remove any server active directory and essentially remove all safety factors. This will give the idea of where to start.

  If you take a quite basic set, 2 Windows 7 workstations without a Firewall window activated, they both work as expected.

  It must be remembered that in firewalls, even if they are able to respond to ICMP if the request is from a different subnet, they will not be because he is recognized as a network abroad. You must know the network on these computers or make sure the computer does not care.

  You may be able to do this by simply adding additional subnets on the advanced configuration of the network card (if it does not take too much address space) as an example.

  Or well, as you have discovered that you can add routes, which is a bit heavy and inconvienent, but effective.

• Routing between VLANS in one direction

  OK... so I don't know if I can do this, but I'd like some input cases possible.

  Network equipment - RV120W, SF300-24

  VLAN10--> switch in VLAN, internet access - preferably just 3 addresses

  VLAN20--> switch in VLAN, initiate connection with VLAN10, VLAN30, access internet (I realize that there is a risk to security, but inevitable)

  VLAN30--> switch in VLAN can access internet

  VLAN40--> Internet access only, can not pass

  I the installation of circuits between the devices and assigns him VLAN quite easily, I'm not sure how (or if its possible) to create routing tables / settings to accomplish.  I am not able to do this on a SF300, but some tips you would know - even if I accomplish only part of what would be ideal.

  Hello Smith,

  I suggest the creation of access list (ACL based IPv4) for your configuration (assuming you do your routing inter - VLAN on the switch). If you are routing inter - VLAN on the RV120W, you may need to create the list of access on the router instead.

  See the article on more details on the ACL on SF300:

  Configure lists of access based on IPv4 on the 200/300 series managed switches

• SF300 ARP Table overflow

  I have a SF300 mode layer 3 interVLAN routing with four other SF300s in mode layer 2.

  In my syslog, I noticed many errors of ARP Table overflow. We have wooded with over 300 knots somewhere that does not surprise me to see some overflow of ARP table but not at the rate I am actually receive.

  I should set the agreesivly age the CAM table aging time? Setting the time for a shorter duration will cause a potential ARP storm?

  Hi Carrick, your comments are accurate. Much of the firmware updates are not well and it was generally a best practice to factory default of the switch after the updates.

  I've always felt lost switches something after the 1.1.2.0 release as far as performance goes even with excellent features improvements that came after.

  SX500X switches are probably about the same price as a switch 3750 in some markets. Even if it was an additional amount of $500 per switch the 3750's would be a better choice as long as you can also offer contracts. SB switches are growing a lot and they are a very good product, especially at the price point. The guarantee is fabulous and the support is good.

  I don't think the SB switches are still in position to be a central switch, certainly access or switch of the light distribution, they are more than perfect in most scenarios.

  Personally if you have a choice, I would not be surprised if you backward to 1.1.2.0 and missed the switch more or observe all the warnings of performance you would disappear. Personally, he was my most favorite release.

• SF300

  I have a question since last 2 on sf300.

  The problem is that sf300 isn't compatible full dhcp, so I put the different internet modem.

  I plugged an internet modem in vlan 1 kind of this vlan, users can access the internet and default gateway is nothing else than the Internet modem ip.  user in vlan are not communicate with other vlan because other users of vlan default gateway is the ip address of the Interface.  How can I give access to vlan 1 to access the other vlan.

  See attachment.

  I used a static route in any one or all 3 devices.

  Thank you

  Hi Sir, the switch cannot perform NAT functions, so only the vlan connection to the modem can work this way. The default gateway of the connecting servers must be that of the SVI switch while operating mode layer 3. The modem would require the static routes (not the switch) If you want as virtual LANs to internet connection and intervlan communication.

• SF300 Questions of the of the VLAN IP address

  I bought 3 SF300-48 switches to work AP1131AG Aironet wireless with my APs. I have now spent 1 VLAN for all to have a Guest_Wireless VLAN 200 as well as the default VLAN 1 for my Corporate_Network. The question that I have is that any client on my default VLAN receives an IP address from the DHCP Windows Server without problems, but when you connect to the guest VLAN you can't obtain an IP address.

  So, I also have a Cisco 3560 G Router (default gateway) which has the same Aironet AP1131AG AP connected to it with the same config as additional points of access files and it works perfectly. I can connect to each SSID wireless (Corp. Vlan1 or comments Vlan 200) and get the IP address of the DHCP server.

  I also have the network below plan and was seeking help in the SF300 configuration to allow the IP to get on the subnet, Vlan 200. I also tried to connect my laptop directly in the SF300 and configure the port to access the Vlan 200 and I still can't an IP address.

  Any help would be appreciated...

  Aaron

  Hi aaron, on the 3560, the port mode is defined as the encapsulation dot1q and one vlan specified native? Also, for the SF300 vlan natif native is 1, you tag vlan 200 to the trunk?

  The Catalyst switch works differently than the SX300 switch in this sense.

  Note also, will not attend the VTP SX300 or PAO.

• SF300-48 - I want to have two VLANS communicate

  I want to segment our users our wireline users wireless and I bought this switch in the hope to be able to do.

  How can I do this?

  I've already put the mode switch to layer 3.

  I created the second VIRTUAL LAN and assigned it and IP.  How can I get the VLAN wireless talking to data VLAN?

  Thank you!

  Hi Scott,.

  Your only sends me a part of the story, but we move forward another step and add a static route to the WAN router...

  A network diagram, even done with paint would be fantastic to understand the topology of your network.

  So no history full of how the network is set up, I have to work on assumptions.

  PC in the 10.1.32.0 network used the WAN router as the default gateway. You put the default gateway address of VLAN1 and VLAN2, IP switches, according to which VLAN the PC is.

  I would like to work on the assumption that the address IP of VLAN1 to the SF300 switch is 10.1.32.100

  step 1. Put the PC in VLAN1 back if its default gateway is 10.1.32.1.

  step 2.  Add a static route that is appropriate in your WAN router so that it knows how to send traffic to VLAN2

  It could be something like, and I'll cite the statement of the itinerary which must reside in your WAN router.

  To get to 10.20.32.0 network with a mask of 255.255.255.0 Gateway 10.1.32.100 (IP address of vlan1 on the SF300.)

  This should then hosts of PC in VLAN1 and the router to learn how to get traffic to VLAN2.  the router will redirect traffic to the switch SF300 and he has a way to interface to VLAN2, so he certainly knows how to get to VLAN2 IP packets.

  If the WAN router knows where VLAN2, go via the SF300 switch, then he might be able to the Internet of NAT traffic then this second VIRTUAL local network.

  We are not finished here, more is yet to happen, such as the DNS and DHCP resolution for hosts in VLAN2 and possible NAT problems according to the capabilities of your WAN router.

• The managed behind router switch remote access?

  What is the best way to access remotely to a switch behind a router?  I will use a switch SF300, and there is no server.

  For points of access (PA) behind a router, I give each a diffferent LAN address and port number.  In router I have forward TCP traffic with the single port/LAN IP.  Then using the port numbers with the address of the static router, the browser can remote access to the router or the attached AP.  But where do I put the managed switch LAN port number?  Assume default is port 80 and I would change to 8001 to switch #1; 8002 to switch #2; etc.  Could not find this info in the manual of configurtion.

  Hello

  At this point, I would recommend a call to the Cisco Small Business Centre at 1-866-606-1866 support so that action can be taken and your configuration can be reviewed.

  I have reproduced the concern here and I am able to remotely manage my switch SF300 with an RV082 as the router.

  My rule in the RV082 are as follows:

  Creating a custom topic UPnP service.  Create SF300 application name (it is a basic text field and can be any name), 8001 an external port and internal port 80.  I send to the address IP internal SF300 switch and click the check box.  From there on, I select Add to the list.  Once it appears in my list, I then click Save settings at the bottom of the page.

  Thank you!

• Tips to add a VPN router to my current network configuration

  Dear all

  My apologies if the answer to this question already exists, however, I searched in many situations and none seem to match what I'm after.

  I currently have an ISP modem/router in Bridge mode connected to a TC of Apple which is my wireless router, I have 2 Express airport connected to this acting as the extensors of the range.  I have a VPN service through the MyPrivate network I activate on the desired device when required and everything works fine.

  What I want to do now is to be able to use my AppleTV and burning Amazon via the VPN as well so you need to add a VPN router in the configuration.  I want to finish with 2 wireless networks running together for these devices who need VPN and those who are not.  I don't want to lose the opportunity to extend the network to express it however airport.

  If someone could explain to me if this is possible and if so how do I set up the network.

  Thanks in advance

  Mark

  Basically you would need a device that supports VPN-passthrough and VLANS for your goals of networking. MyPrivate network, seems to be a VPN SSL, which is a user-server configuration. In other words, you install a client VPN on your Mac and you connect to the VPN network MyPrivate server to establish a VPN tunnel.

  Networking two or more "separated", should be using a router that supports VLAN services. Each segment of VIRTUAL local area network, in essence, would be a separate, she either wired or wireless network or a combination of both. This would probably be the 'easiest' part for the installation program.

  Now how combining the two would be the question, and I don't know what would be the best way, or even if it is possible.

  A few thoughts:

  • Use a router that supports VLANS. Create at least two VIRTUAL LAN segments. One for Apple TV & Burns, one for Internet access in general. Connect the device to VPN client host on the first segment, and configure for Internet sharing.
  • Download a dedicated VPN network application that supports hosting of third-party VPN clients, like yours. You would still need a router that supports VLAN to provided separate network segments.
  • Hire a consultant network. Let them know what you the goals of networking and ask them to offer potential solutions.

• Time Capsule as a router

  Instead of the cable company router, can I use my time capsule to be a router?

  The time Capsule can function as a router, but not a modem. If what you provided your cable provider is a simple modem, then the time Capsule will work. However, if they actually you provided a combination modem and the router, also known as a gateway device, then it wouldn t.
