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?

I've a network with 28 computers and 2 servers. Each server have a double Gbit port configured in Load Balancing & Fail Over.Now, I want to buy two Cisco's Switch SG 200-26 and I would know the best way to connect them and if it's possible to interconnect them with more than one cable to share the trafic.
1. Is this following solution a good one (does the link between swhitches will work when computers will access to servers) ?
2. Is this next solution possible ?
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?
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)
Our "standard" trunk config is:
switchport trunk allowed vlan 228,229,265-268
switchport mode trunk
mls qos trust dscp
storm-control broadcast level 20.00
storm-control action trap
no cdp enable
spanning-tree bpdufilter enable
spanning-tree guard root
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"?
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).
How to erase or remove configuration file from ESW 500 Series Switches?
View 2 Replies View RelatedWe are migrating from a Microwave T1 WAN to a Fiber ring WAN which I'll be connecting to our providers Ciena Metro E switches. Eventually we are going to move away from the routers, but the network is a little too complex as well as spanned across a lot of miles. Since I am the only networking personnel here, I would like to first simply migrate to the fiber by simply moving the connection configs off of the T1 interfaces, and onto one of the Gig interfaces on the 7206 and on one of the Fe interfaces on the 3900 (which is actually a 3700 series because the line card on the 3900 is toast). If this works, I will need to purchase Fe line cards for the 7206, because I found out that the virtual interfaces do not support Policy Mapping for our QOS and Multicasting.

View 1 Replies View RelatedI 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’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.
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.
View 9 Replies View RelatedCompany 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.
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.

Best practice for connecting cisco switches over fiber.
I'm working with a customer who has an SGE2000P and a Catalyst 2960 to setup and configure a single mode fiber link. The SGE2000P has an MFELX1 fiber GBIC and the 2960 has a GLC-LH-SMD GBIC. When I have the customer plug in his fiber, there is a power light that comes on on the MFELX1 GBIC. Neither GBICs/switches show that a link or activity is occurring, but the presence of that light makes me think that they are connecting somehow. Are these two switches/GBICs compatible?
