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 :: Catalyst 3750x 24 PS POE With C3KX-NM-10G Uplink Modules?

Sep 5, 2012

our network is spread over  15 floors and each floor we have 5-6 switches. we are planning to purchase cat3750-x 24 ps poe with C3KX-NM-10G  network modules. Each floor has two up links  to the core  switch  with  single mode fiber and other being the multimode.Suppose if we are purchasing 75 switches  do we have to  purchase 75 C3KX-NM-10 G  modules.? or  can we limit our purchase with 15 C3KX-NM-10G   sothat two uplinks from each floor can be made?  since network modules are optional cost factor is invovled. Or any issue with stacking ? the SFPs will be LR  and LRM MODULES.looking for an answer ? whether the new usb type console cable comes bundled with  cat350x or shall we have to order separately?

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 :: CiscoView Not Displaying All Switches In 3750-Stack

Apr 17, 2012

I am running LMS 4.1 and have an issue with Inventory: I have a stack of four 3750 switches, but only two of them are showing up in CiscoView. If I right-click - Topology - Device Report ;  I see all four switches. The switches are standard 3750 switches and should be included in the Device Packages for CiscoView
Also if I go Reports  - Detailed Device ; I see the same two devices show up under Module Information. However when I go to Reports - Device Attributes ; I see all four devices correctly displayed.
I have tried and deleted and added the stack in CiscoPrime, but with same result.

Cisco WAN :: 3750E - SRR-Queue And Traffic Prioritization?

Jul 12, 2011

I have two goals on my Cisco 3750E -
* Limit bandwidth to match carrier provided bandwidth (10M ethernet port, but only 6M provisioned)

* Prioritize some traffic over others through the use of a priority queue.
I have come up with this design:
access-list 100 remark priority traffic
access-list 100 permit ip any
access-list 100 permit ip any


How do I know?  Is there a show command to show priority packets?
Am I right in assigning dscp 46 to this interesting traffic?  That way it goes to queue 2?
Am I right in applying the priority-queue out command to the interface?
We also have voice traffic.  But I think i can trust it to queue up into the router with trusted dscp

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?

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?
