Cisco Switching/Routing :: WS-C2960S-24PD-L PoE+ 10Gb Switch Using 1Gb Uplink
Jan 24, 2013
I have configured about 20 of these switches now, and notice in the port listings a TE1/1//1 TE1/1/2 and GI1/1/1 GI1/1/2 uplink port. There are only two uplink SFP+ ports. I now have a reason to install with a 1Gb uplink to the Core. I am using a GLC-LH module at each end. I did configure the TE1/1/1 port for the uplink. Does not work though..Do I need to configure the two GI1/1/1 and 1/1/2 ports for uplink, remove the TE configuration for the uplink to work? Using the UNIVERSAL code with a LANBase license.
we have just purchased a few 3750x's that we intend to add to our 3750g stacks. We've purchased the 10gb uplink modules, C3kx-nm-10gt, but when they are installed they are not appearing in the switches web gui nor can you configure them correctly. If we upgrade a 3750x to 15.0.1 they seem to work fine. All of our current 3750g's are running 12.2(58)SE2 IPBASE so we don't really want to have to upgrade them all to 15.0.1
Are we missing something or do the 10gb modules only work properly with ios 15.0.1?
My 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?
Recently on two switches, both being same cisco WS-C3750E-24PD, running with same IOS c3750e-universalk9-mz.122-58.SE2.bin got noticed that the license state of one switch is showing incorrectly as shown below [code] I will not be able to execute any changes/modifications on switch as of now.
I need 10gigbit uplink for this switch. What are the other devices that i need order along with this device.And what is the diff between X2-10GB-LR= and CVR-X2-SFP.if i take CVR-X2-SFP, in future how can i upgrade from one gig to 10 gig?for current use i need 10gig support required. so what are all the other devices that i need to order.Fiber multimode and distance 15Mt only.
We have several of these WS-C2960S-24PS-L running 12.2(55)SE5 C2960S-universalK9-M and need to upgrade to a better.IOS since we have a sitution where CPU would get to 100% but we have only a few ports connected.Also we have several of WS-C3750-48P running 12.2(55) SE6 C3750-IPBASEK9-M.
I implemented the 3560E switch, this one have two Giga bit ethernet/10-Gigabit Ethernet module slots. I used the Twin Gig Converter Modules and one SFP. All configuration was applied in the Ten Giga bit, however the interface giga bit ethernet is UP UP state and the Ten giga down down.
I was trying to uplink a switch today on a 1500m run of SMF. I have a 6509 core switch with a 16 port GBIC module. On that end I have a WS-G5486-LX with a 3m SC to LC patch cable.On the other end I have a 3750G with a GLC-LH-SM SFP. I have checked my fiber path and it seems good, (by sight, did not have an OTDR avialable).I can't get the link up at all. Tried swapping Tx Rx at one end, Tried different transceivers. Tried different patch cables. Nothing worked. At about the mid-point of my fiber run the cable passes through another network closet with a core switch for a separate network. If I break my fiber path there and try to connect in either direction it works. The only differences are the length of the fiber run and that the core switch on the other network has a CLC-LX-SM SFP.Is it the distance? Or is there some issue connecting a GLC-LH-SM to a WS-G5486-LX?
Does GLC-GE-100FX is supported on the WS-C2960S-24TD-L. I don't see this switch listed under the compatibiilty matrix.URL,But the datasheet for the 2960S says this:"The Cisco Catalyst 2960-S with SFP+ does not support the GLC-FE-100BX, GLC-FE-100FX, or GLC-FE-100LX."But it provides no reference for the GLC-GE-100FX,The easy answer is, no the 2960S-24TD doesn't support it.
I have a Cisco WS-C2960S-48TD-L with 12.2(55)SE2.This is a standalone switch, not in stack, and with no order it reboots itself looking for a new master election. On logging i have nothing, but connected with console cable i see the following after 2 minutes of not showing anything:
Waiting for Stack Master Election... ... The switch reboots and: ... *Mar 1 00:00:12.289: Read env variable - LICENSE_BOOT_LEVEL =
After searching online i have no seeing nothing about disable the feature of the stack so i configure the priority for the "switch 1" to 15 and configure it the switches 2, 3 and 4 to no provision, although this switches don´t exist:
SW_ACCESS(config)#switch 1 priority 15 Changing the Switch Priority of Switch Number 1 to 15 Do you want to continue?[confirm] New Priority has been set successfully
With this new configuration the switch has rebooted again.Why on a standalone switch the stack is rebooting my system?Is it any feature to disable the stack?
I need a L2 switch with dual AC power supply and RJ45 uplink The optin I got was WS-C3560X-48T-L + C3KX-PWR-350WAC , but the problem is with uplink . There is no RJ45 1G uplink , there is only option for SFP uplink The another option was WS-C2960G-48TC-L , but there is no dual AC power supply option a good model ( Dual AC power supply , RJ 45 uplink ports (Gig) , with 48 port 100/1000 UTP)
I have a new Cisco 2960 S series switch with a basic configuration that needs to be uplinked or daisy chained to a Cisco 3750 switch. I am not getting any connectivity to the network with either a straight through or crossover cable. the port remains in amber but a 'show interface' indicates that the interface is up. I can manage the switch with a PC patched into any port on the switch with a static IP address. Must be something very simple that I am missing. Outlined below is the configuration.
I want to connect WS-C2960S-48TD-L switch to WS-X6708-10G-3CXL module in Cisco WS-C6503-E switch. WS-X6708-10G-3CXL is C6K 8 port 10 Gigabit Ethernet module with DFC3CXL which requires X2 module. on the otherhand, WS-C2960S-48TD-L requires SFP+. Now is it possible to interconnect these two switch interfaces if I use LIU in between. or does WS-X6708-10G-3CXL module supports CVR-X2-SFP+ to use SFP+ transceivers.
I have a pair of 3750E-24PD-S stacked together, it seems after stacked together the stacked switch always flood the console screen with these messages which are not true: [code] Switch-2 is the stack member, Switch-1 is the stack master. The RPS fan failed refers to RPS2300 or the internal power supply of 3750E? Even when I turned on the RPS2300 the stacked switch still display the messages. Also I have two RPS2300 serving stack master and stack member respectively both RPS2300 were switched off why the messages only refer to Switch-2 and not Switch-1? [code]
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?
Created two 6509s as VSS with just one 10gb connection?I know it is recommended to use both the 10gb connections on the sup-720 from below configuration guide
" Information about VSL Topology # A VSS contains two chassis that communicate using the VSL, which is a special port group. Configure both of the 10-Gigabit Ethernet ports on the supervisor engines as VSL ports. "
I 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?
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?
the nexus 7k or 5k can be devided into 4 virtual devices ( using vdc)and making 8 uplink ports in the 2k will allow us to use the extender for all the 4 vdc's with 2 uplinks ( for redundancy ) from each vdc
I have a two Cisco 4510R each with two sup V-10GE redundant. The code on these sup modules are 12.2(31r)SG3. I need some assistance in getting this setup worked out. I have all four of the 10GE populated with appropriate optics. I setup a link from one 4510R to the other using these interfaces. From the documentation I found I had to use Tengi1/1 and Tengi2/2 as the redundant pair. I plugged the up link into these ports. The Tengi1/1 (active supervisor) links up and works fine. But when I look at the ports port Tengi2/2 it isn't showing link or active. Now port 2/1 (nothing plugged into it) is showing as active.
Now is the redundancy supposed to be 1/1 and 2/1? If so, the switch is in production, when I move the connection over from 2/2 to 2/1 will it cause a outage? The reason for this is I now have a system with a 10G port and would like to utilize one of the other 10G ports. Is that possible? Or does it have to be a lag/redundant up link to work (say to another switch)?
