the incoming fiber on ports 9 and 10 are on different subnets. I need to map the subnet on port 9 to ethernet ports 1-9 and port 10 is on its own. I have the device IPv4 address set to a static address on the same subnet as port 9. I don't know if there's an easier approach, but I attempted to map the ports using vlans (See the attached screenshots). We don't yet have the fiber link established for port 10, so I haven't had a chance to test, but I wanted to confirm that my configuration is sound. I used the default vlan for ports 1-9, because I need to manage through that subnet. I added vlan 10 for port 10, but I don't know if I have it configured correctly.
I have successfully set up a VLAN on my primary switch which is an SGE2010. I have 3 other switches is other buildings connected in series. The next in line is another SGE2010 and then a SLM2024 and an SGE2010. Each are connected with Fiber and I'm not sure how to set up the switches so that the router controlling VLAN 2 will push IP addresses to the clients on that VLAN and allow internet access. We're using it as a guest VLAN for our customers to have internet access. I have those GBIC ports set up as trunks right now except for the SLM2024...I'm not quite sure how to set that up. The VLAN is set up on each switch exactly the same though.
We have a scenario where we want to connect 14 access layer 2950 switches to Core switch 3750 via optical fiber in a LAN.What model of 3750 Switch should we use to tackle this situation.I have learnt that WS-C3750X-24P should support it.Isnt it?
Can we use optical fiber SFP module to connect 2950 switches to core switch?Does Cisco 2950 Switch support optical fiber sfp module?
My question is about WS-C3750E-48TD-S and WS-C3750E-24TD-S Switches
What are the limitations of the mapping of VLANs on this device? Is it limited by number or by interface? Does the configuration of an interface has spread all interfaces ?
I have a stack of 6 switches and I want to add another over the gbit connector using fiber. I already connected but I can acces the network from the new switch. I don't have any issues on my Stack all resources are available Do I need to do some special setup or connection to enable this? Can be stacked like the others? I already usen the 2 stacking port can i Add another switch?
We have an ASA 5505. 5505 comes with two default vlans 1&2 with each of them marked as inside & outside respectively.My query is , if i do not want to use vlans on 5505 and only want to use the Ethernet ports as pure physical layer 3 ports, is it possible?i.e. i want to assign a layer 3 ip address on eth0/0 and eth0/1 and make them as the inside & outside interfaces rather than vlans. is it possible to do away with vlans in 5505 & will it work otherwise?
We have a project in which we are using 34 Cisco SG200-18's each with a MGBLX1 (LC Single Mode Fiber) SFP mini-GBIC.All the fiber's come back to one building where we must "bridge" all 34 fiber connections. What hardware should be used to accomplish this? A L2 switch? For example, a 12 port SFP Switch with Fiber SFP's accepting the first 12 fiber connections, then other switch with SFP for the next 12 and so on, until there is a overall capacity of 36 and having patch cables between the 3 switches?
what cisco or non cisco hardware would work with these SF200-18's to accomplish this?
I have an old Cisco 3500XL I am using for my home lab, but was wondering can I use the fiber ports to connect to my PC. I have to correct NIC interfaces but no link indication. I did make sure the port was no down, but sill not link.
i was able to configure (via SF200 web interface) a port mapping from port FE17 to FE7.i have supressed this port mapping.
when i try to reconfigure a port mapping from port FE17 to FE3. The SF200 web interface crash. the SF200 seems to reboot.
i have updated the SF200 firmware from V1.1.2.0 to V1.1.2.9.44.when i was able to configure (via SF200 web interface) a port mapping from port FE17 to FE7.But after having suppressed this port mapping again, i was not able to reconfigure a new port mapping from port FE1 to FE3 (the SF200 hangs).
I was checking some things on my Cisco 4500 and spot checking some of the ports. Using CNA it says it is at 10. The web browser to the switch says Full-duplex, 1000Mb/s, link type is auto, media type is 10/100/1000-TX on port 6i/18 The CNA says, so what would cause the difference?
We've just purchased a WS-C3750-24FS-S, only to find that the 100baseFX ports will not work over Single Mode fibre, backhaul links. Any way or a device that convert from MM to SM?
Vlan 10 is the management VLAN, and it uplinks to our border router.Vlan 20 is the workstation VLAN, and all workstations point to the switch as their default GW? Vlan 30 is the ip phone VLAN, and all phones use this as their gateway.
I would like to put a LAG between said switches, we have some servers on the ip phone switch that need to be accessed by the workstation clients, and the single 100mb link through the router is probably not going to be enough.As I understand it, because the switches have different networks on them, a simple lag will not work. I did create a lag, and assign ip addresses to each side, however in that mode, it doesn't appear I can block vlan 10 from transiting the LAG, and with out that block I will end up with a logical loop, and spanning-tree will block one of the uplinks, or the LAG itself.
I was looking for configuring QOS for two VLANS i have created. these will be for voice traffic vlan 22 and video traffic vlan23. i also have three other vlans for pc's, wireless devices and our cnc machines. we have 5 switches that are all SG30028P's with a single switch doing the intervlan routing (operating at layer 3). all of the switches are trunked back to the main switch and ive been through the guide written on how to do this on a single switch which i dont think is layer 3.
I'm going to have several SG300-28P switches to setup. I'll need to create multiple vlans for data, voice, and wireless traffic. I have the following questions in setting up this configuration:
1) For managing the switches via IP, will LAN1 be the default management network? Should I create a seperate VLAN for managing the switches?
2) For uplinking the switches together, I plan to trunk a port to connect the switches together. What's the configuration on the trunk port to forward all vlans from one switch to another?
3) On some ports, I want to configure a trunk for two vlans (Data and Voice) where the phone has a pass through for PC. The phone supports tagging for the PC and the VoIP traffic. For example on port 10, would VLAN 100 and 300 be set to tagged?
I am specking a SRW2008P-K9 switch for a customer. They are using MM 62.5 fiber. I need to know what Gig SFP will work for them. I am also quoting them a WS-C3750X-24P-S.
I have a wlc2112-k9. I have succesfully setup a WLAN with 802.1x authentication and dynamic VLAN assignment. The issue I have (and maybe it isn't an issue and just the way the controller works) is that if the vlan interfaces I have defined are connected to different ports from which the default interface for the WLAN it doesn't work.So for instance, I create my WLAN and set the interface to the management interface (which is connected to port 1). I then define all my other vlan interfaces that could be returned by my radius server.[code]
Port 1 is configured on the switch on vlan 21. If the radius server returns a VLAN ID of 102, 104 or 106 my client successfully connects to the WLAN but it gets put on VLAN 21. However if I move the vlan interfaces above over to port 1 the client correctly gets put on the correct VLAN.All ports on the switch are configured as trunk with the native vlan set to the corresponding value that is set on the WLC.
Is this just the way the controller functions? That it can't assign a client to a different interface that is connected to a different port from the default one setup when the WLAN is created? I would have just though that if the radius server returned VLAN 102 that it would find that interface and connect the user session via that interface regardless of the port it is configured on.
I have a test switch (Cisco 3550) that I want to set up with 6 Vlans and 2 trunk ports. I want to be able to access a virtual server conected to the trunk ports from the switch ports. Ports Fa0/1 to 8 are in a vlan port fa0/9 to 16 another vlan etc. Ports Fa0/47 and 48 are the trunk ports. This is a lab environment so the the switch is the only device being used.
I am trying to set up three vlans across two switches. The switches are Cisco SG200 and SG 300 series. There are 20 devices connected to the two switches including a router for Internet. Among these devices are five wireless access points all hardwired to the LAN. If I understand correctly the first thing I have to do is aggregate the two switches. I ran two cat5 cables to ports 1 and 2 of each switch. As I understand it all I need to do is to create SAG with the two ports on each switch. I think I need to use tagging but I don't really understand how to do this. Once I get the trunking set up correctly I want to create one vlan to which all devices will belong for Internet access. The other two would be for data and VoIP. Do I create vlans with the same name on both switches? When I assign the devices (by port) do I need to enable tagging? Which type of port setting should I use? I am assuming that by including the acess points in the vlans will mean that any wireless device connected to them will have acess to the Internet and the devices in the same vlan.
Trying to replace 3Com Superstack II Switches (3C16980) with 100Base-FX Modules (3C16970) with a Cisco solution. Existing Fiber connector in Network closet on both ends is an SC connector (picture attached). What Modules, adapter cables do I need to connect to an SRW2048 switch at one end an SRW2024 switch at the other? Will this solution provide a Gigabit connection over the Fiber ?
I am looking at using SRW2048-K9-NA with MGBSX1 module at one closet and SRW2024-K9-NA with MGBSX1 module in the other closet at the other end of the Fiber cable.
I found an adapter cable that will convert an SC male to an LC Male and it looks like it will work but I have no experience with fiber. I attached a picture of this adapter as well. It is listed on line as - 1ft Fiber Optic Adapter Cable LC (Male) to SC (Female) Multimode 62.5/125 Duplex
We’ve just begun the transition from our old 3Com switches to new Cisco switches and we’ve encountered interoperability problems as we start the transition.Goal: Extend 6 VLANs (each representing an IP subnet) via fiber from a port on the 3Com 5500G-EI to a port on the Cisco SG-300-52
We assign an IPV4 address to the Cisco SG-300-52. We can successfully ping/web-manage at this address if we do a temporary copper jumper from a 3Com switch to the Cisco. IP address is in the subnet assigned to VLAN7•2) At the 3Com side, the fiber port is set as “hybrid” and is passing VLAN 1 untagged; VLANs 3-8 tagged•3) At the Cisco side, the fiber port is set as “trunk” and is defined with VLAN 1 untagged and VLANs 3-8 tagged.
If I try to change the management interface on the CISCO from VLAN 1 to VLAN 7 (as I would on the 3Com), I lose connectivity over the temporary copper connection•B)
If I remove the temporary copper jumper from the Cisco (keeping the “working” management IP address) and create the fiber link between the 2 switches, I lose connectivity to the management IP , If I set the 3Com fiber port to “access” and make the fiber connection, I can ping the management interface – but of course, I can’t pass the other VLANs to untagged access ports on the Cisco – and it has the fun side benefit of messing with IP management settings on other 3Com switch stacks attached to the 5500G-EI. However, it does demonstrate that we can get network traffic communicating over the fiber link between the 2 switches.
How I can proceed to a) have the management IP address in the IP subnet defined on VLAN 7 while passing the other VLANs to access ports on the Cisco? BTW, I’m a networking neophyte (it’s a very small part of my job and I do it infrequently), so I prefer to use GUI management to CLI options, although I can perform CLI configuration if presented with the right commands.
We have a stack of 2960S, and have a new client that wants to connect via diverse fibre to both switches(From 2 switches on there side). We currently run MST and client is (currently) running PVRST. The 2 links will be trunks (With the same ~5 vlans running over both)
So after recommendations on what is needed to avoid L2 loop, and to ensure we force one trunk port to be the "primary" for those vlans, and the the other trunk port to be "backup"?
due to upcoming changes to our network I'd like to be able to pass vlans across the FE ports of a Cisco 1841 router.1 port would go to a managed switch and then to local devices on different VLANs.the 2nd port would go upstream to a Cisco 3825 at a different location which would then connect to the internet.due to monitoring behind the Cisco3825 we would like all NAT to occur on the 3825.
what I would like to happen is this example device connected to port 7 on managed switch gets an IP (10.0.7.10) from the Cisco 1841 in VLAN 7 (10.0.7.0/24).traffic from that device goes to the switch, then in f0/1 on the 1841 and out f0/0 still with the same IP info, no NAT occuring.traffic is received on the 3825 port 0/1 and then NAT occurs and out port 0/0 to the internet.
My customer requires the hostport on an access switch to be allocated to a specific Vlan based upon the AD Group that the user is a memeber of ? I am planning to setup NAC in a Real Gateway OOB deployment, using an ACS 5.2. I was initially thinking that the initial authentication server would be the ACS and then the AD, which using group mappings within the AD, I could then assign the user to a specific ACS group and then pass a Radius attribute back to the NAC manager for processing?
Company I work for just moved into a new location. We have two data closets which are patched as independent entities, with no Ethernet tie connection. These closets are roughly 100 feet apart.
There is a fiber connection that runs between both closets, that the previous tenant used to connect the switches. I have placed a Cisco 2960 switch in each location, and added one mini SFP gbic's to each switch. After attaching both sides, neither light up. I do a sh inter gig1/0/49 on each and shows 'down down' (not admin down).
What is the trick on getting these to communciate, do I need to configure these ports, and are they supposed to light up?
What I am trying to accomplish is to get the one closet that is completely cut off, communicating by logically stacking, or 'daisy chaining' via fiber.
I turned off the lights and popped the fiber out, and I do see a faint red light (I did not look straight into it), so I think the fiber is active.
we bought the Cisco 1921 ISR with the HWIC-1GE-SFP to get a router that would be able to connect via fiber to our switches. I called Cisco and their reps recommended this router/HWIC pair to me.
I have got the basic configuration out of the way and I have discovered my router with CCP, now I would like to know how I can configure this HWIC. I have the SFP(GLC-SX-MM= ) installed correctly and it is connected to our test switch via an LC/LC cable, but when I do 'show ip interface" all ports are down except the one my workstation connects directly to the router with (gigabit0/1).
When it comes to fiber optics my knowledge is very limited. All I know is that they can carry data at high bandwidth for a long range at blazing speeds etc.My boss has asked me to link several buildings to the network and I am led to believe that joining them through fiber optics to be best since we are expecting a lot of data traffic between.I have done the normal RJ-45 networking with Gigabit networking in my organisation but need your assistance on how to join each of the buildings through fibre optics.So far this is my plan.Draw up the fiber optic lines from the main building to each building.All the buildings have Gigabit Cat6e cabling and network in each.I am planning on using a single mode media converter to convert the end of the fibre optic to the normal RJ45 connector and plug it to each switch at each of the ends of the fiber optic cable .Am I going in the correct direction?I don't even know the gadgematics required except for the cables them selves, crimping tools, the media converter. There is about 300-400 metres in between of each building from the main building.Also, I believe that we need to create cross over cables as in the normal way we do in connecting 2 switches. Your input is very valuable to me.
I want to "stack" a couple 300 series gigabit switches with fiber using a pair of MGBSX1 GBICs and a single LC to LC patch cable.Is there a minimum supported patch cable length in this configuration?
I have issue with connectivity 3750G with Dlink Switch, it cannot connect to non-cisco switch with fiber , But CISCO to CISCO switch it shows connectivity. My question is that is there any configuration on Cisco 3750G switch to connect with non-cisco switch through fiber (SFP) ?
I need to connect 4 Floor Building with 4 Cisco 2960 - 48 ports switch each other and it needs to be through a fiber. So all PCs connected to each switch would reach the LAN/WAN from the other switch. (attached is the image here with)
I see that the 2960 has 2 SFP ports each port of each switch should connect each other or how?
My simple question is:
1. What cable / patch code I have to use = Single-mode or Multimode? ( distance for each switch will not more then 25 mts)
2. Do I have to use SFP or SFP+ module?
3. What kind of SFP/SFP+ module I have to use = Single-mode or Multimode?
4. What kind of connector should patch code have = LC / SC or ?
5. How to connect each switch with redundancy like ...each switch should be interconnected with each other or I have to choose Cisco 3750G which has more then 2 SFP ports (option#1 & opetion#2 = attached here with) =
Best practice for connecting cisco switches over fiber.
I have 4 workstation at 4 different power substations. Each substation have switches. All substations is link with fiber optic cable throw switches. Each substation has 100 relay (IED) with different IP address it connect with substation switches. The IP address of substation is[CODE]
