Cisco Switching/Routing :: 4500 Can Connect 10Gb SFP+ To Standard 1Gb SFP

Nov 15, 2011

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?

Cisco Switching/Routing :: 6509-E VSS 10gb Port Count?

Jan 15, 2012

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.
"
 
But will the VSS come up if I use just the one?

Cisco Switching/Routing :: 3750 Stack - 10GB And 1GB Connections

May 22, 2012

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?

Cisco Switching/Routing :: 5596 - Extending 10Gb/s LAN Between Sites

Dec 14, 2011

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?

Cisco Switching/Routing :: X2-10GB-LR And Receive Power In 6500

May 1, 2012

We are having troubles getting a 10Gig interface to come up with a carrier... it shows down down.We are using X2-10GB-LR on a 6500 and SM fiber, distance to carrier hand off is about 90 feet.
 
According to: [URL]
The receiver power on a X2-10GB-LRis

Our carrier is sending at +5db. Currently the interface is down.
 
My question is; would the interface even come up if it is receiving a powerful signal?
 
Here is DOM output for our interface.

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.

Cisco Switching/Routing :: Nexus 5548 10GB-LR Interfaces Not Coming Up

Jun 21, 2012

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. Copies of the different show int commands can be found at the end of this text.

Cisco Switching/Routing :: EtherChannel On 3750G-16TD-S And 3750x-48T-S With 10GB

Nov 20, 2011

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 ?
 
Q. What performance of the 10 Gigabit Ethernet port on the Cisco Catalyst WS-C3750G-16TD switches?

A. The Ten Gigabit Ethernet uplink on the Cisco Catalyst WS-C3750G-16TD switches is 1.25:1 oversubscribed and provides maximum throughput of 8Gb/s.   –

Cisco Switching/Routing :: Catalyst 2960S / Downgrade 10GB Twinax CU SFP Cable To 1GB?

Oct 30, 2012

specifying Cisco devices and I've made an error.I have 2 Catalyst 2960S switches (C2960S-24PS-L).Based on this snippet of web copy from the Cisco website:What's new for the Cisco Catalyst 2960-S Series Switches with LAN Base Software: # 10 and 1 Gigabit Ethernet uplink flexibility with Small Form-Factor Pluggable Plus (SFP+), providing business continuity and fast transition to 10 Gigabit Ethernet I bought a cable assembly "SFP-H10GB-CU3M" (3 meter copper twinax cable with 10GB SFPs on each end).  Unfortunately, it appears after more careful reasearch that my specific model 2960S's are not directly compatible.  , can I force these 10GB SFPs down to 1GB and get them to work with my switches or do I need to return and repurchase?

Cisco Switching/Routing :: 10Gb Ethernet Connectivity Upgrade Required Between 2 6509s

May 1, 2012

We 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.

Cisco Switching/Routing :: 3750x 12.2(58)SE2 IPBASE 10gb Uplink Ports Not Being Displayed

May 28, 2012

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?

Cisco Switching/Routing :: 3560 - Switches Capable Of 10GB Port Density

Feb 5, 2013

I have 3560's in my current environment, operating in the core/distro/access layers. The switches are in a star configuration, performs only layer 2 switching, and utilizes copper (no plans on moving to fiber).
 
With a fairly limited budget, I've been contemplating on upgrading the central node to a stacked 3750X to eliminate that single point of failure, and trunk the rest of the 3560's to the stacked switch. I wanted to be sure that the 3750X switches will be right for my environment (90-100 hosts), and if what I explained above is a good solution.
 
I'm also looking like to upgrade 6-7 of my servers (and SAN) with 10GB network cards. Do the ports on the 3750X have port densities capable of 10GB? If not, what switches provide that capability?

Cisco WAN :: X2-10GB-LR Having 10GB Uplink Between Two Buildings

Oct 20, 2011

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?

Cisco Switching/Routing :: 2960 Setup - Compatible Spanning Tree Protocol

At a college I'm trying to setup a Cisco 2960 to be used on a VLAN 248 tagged on the uplink port that uses Spanning Tree/. Here is the following from the Cisco:
 
show interfaces trunk
 
Port        Mode        Encapsulation  Status        Native v lan
Gi0/1       on               802.1q         trunking       1
 
Port        V lans allowed on trunk
Gi0/1       248
 [code]...
 
On the Alcatel OS6850-48L the following is setup: bridge 1x1 248 priority 3287 Vlan 248 802.1q 5/8 "cisco"
 
I cannot make a change on the Alcatel, I can only administer the Cisco. I was able to get things working fine (as a test) using a Net gear or HP switch instead of the Cisco. However we have a Cisco switches and would not like to have to buy HPs. Is there a compatible spanning tree protocol to use on the Cisco with the way things are configured on the Alcatel. I need to stick to standard RSTP (802.1w) ieee standards and not something Cisco proprietary.
