Is it possible to connect a 10G optics to a 1G optics using a SC/LC multimode jumber. Will changing the clockrate at 1oG side solve the issue? or do i have to have strictlt 10G to 10G link or 1G to 1G link?

View 3 Replies View RelatedMy manager ordered some Cisco X2-10GB-LR in hopes of having a 10GB uplink between two buildings. We put those modules on the switch and we are getting link flap errors, then the ports goes into err-disabled state.
I was later told there is a couple of "hops" between the buildings, it could be a patch panel or a fiber switch, I do not know at this point. My guess is, we are getting link flap because the "hops" are only running at 1GB. Would this be a typical sympton of the link flap error message? and is there any way to test if there is switches inbetween our routers?
I'm looking at provisioning a Catalyst 4500 with a WS-X4712-SFP+E module to allow for future 10Gb connectivity via 10Gb SFP+ interfaces. These cards are backwards compatible with standard 1Gb SFP interfaces but I'm wondering about the other way around; ie. can you populate these blades with 10Gb SFP+ interfaces when they connect to Catalysts with only 1Gb SFP interfaces at the other end?
The data sheets don't really explain this. It seems pointless getting 10Gb SFP+ interfaces for the 4500 when it's only 1Gb at the access layer end, but these access switches will be replaced in the near future (~12 months) and if the 10Gb SFP+ interfaces support connections at 1Gb speeds upfront, it would mean I could retain these interfaces when the access switches upgrade to 10Gb connectivity capabilities down the track. Does the 10Gb SFP+ interfaces are compatible with 1Gb SFP's or only other 10Gb SFP+ interfaces?
Could I connect a WS-G5484 (4500) to X2-10GB-SR (6500)?These two transceivers modules have 850 wavelenght, so it should work right?

View 1 Replies View RelatedI have two 3750 stacks that are currently connected using two1GB fiber connections in an etherchannel. I now added new switches to each stack with 10GB modules in them. We would like to bring up the 10GB connection, but still have one of the 1GB lines as a backup, or even the whole etherchannel. Is there a way for us to make the 10GB the main and the 1GB the standby?
View 3 Replies View Related For a simple 4x sites design for backup consolidation (3x sites connected to one central site), does the design in the attached JPEG make sense and is the configuration achievable using the specified parts?
Brief Explanation:
- Each site is to have servers with 2x 10Gb/s Ethernet (both teamed/bonded/etc) and one NIC on each of the 2x switches in the site (if possible). Each site will also have 2x Cisco Nexus 5596UP Switch (though the P version may be used instead of the UP).
- Two of the sites are within 10KM of the central site
- The last site is about 35KM from the central site
- It is required to have a minimum bandwidth of 10Gb/s between any site and the central site
- I have specified 10Gb/s LW SFP+ and 10Gb/s LW SFP+ (for the 2x 10KM and 1x 35KM sites)
- are there any special licenses needed?
- as asked before, can such a "simple" design work as-is?
- what sort of single-mode fiber would fit the bill (especially for the 40KM link) - 9nm?
We have a site with a number of SG500X switches who are about to have a new server installed.
The server is a Dell ESXi host with a dual port 10Gb NIC supporting SFP+.
I know the primary purpose of the 10Gb ports on the SG500X is for stacking etc. but the switch does come with four 10Gb ports.
Why I wouldn't be able to utilize a 10Gb port as a copper connection to the 10Gb NIC on the server? Anyone out there with a SG500X connected directly to a server at 10Gb?

We are trying to connect 2 nexus 5558UP (5.1.(3)N1(1)) with 10G-SFP+-LR interfaces. The interfaces are not genuine cisco's (smartoptics) but as far as we can tell, they are accepted by the hardware. If we take a look at the optical levels, we can see that the switches can see eachother (double-checked by bringing down one interface to see if optical levels really disappears) on optical level, well within limits. I found a notice about changing debounce timers but this doesn't work, setting it to 0 or 1000 doesn't make a difference.

Any experience with bundling a 10GB interface on a 3750G-16TD-S with a WS-C3750X-48T-S with a 10GB interface. I have worked with 5 different TAC engineers and so far I have not gotten an answer on why the switch will not let me bundle the 10GB with another 10GB interface.
Same switch Stack – not a cross stack.
Tried every configuration possible with no luck. I originally thought it might be the stack-ring speed – I corrected that today and it is running at 32GB –
The only thing I can think of now is it might be a hardware limitation on the 3750G-16TD-S ?

View 1 Replies View RelatedWe currently have 2 6509s with redundant Sup720-3b's and PFC3B daughter cards which are connected together over dark fibre using the Gb fibre connectivity built into the supervisors.
The requirement is to upgrade this connection to 10Gb as inexpensively as possible.
Do I need to purchase new supervisors in order to do this properly or can I use a separate 10Gbe module (we have a spare slot), i.e. can I get away without using the connectivity built into the supervisors?
The other idea I had was putting a couple of 3750-X switches at each end to sit in front of the 6509s and provide the 10Gb connectivity between sites. I could then use the existing Gb uplinks on the supervisors whilst also providing connectivity for some devices that currently connect to the 6509s but could just as well connect here.
