Cisco 3750 - Fiber Connectivity

I am going to connect 6 WS-C3750V2-48PS-S switches on fiber for my 4 floor building,

below is my requirements:

All switches should get connected each other with redundant link (if one fiber cable is damaged second one should be available as a backup, so we will have the redundant link with each floors (not the redundant switch on each floor)

Kindly clarify my some queries as below:

1. My cable vendor shipped me single mode fiber cable for interconnecting the switches, so is this cable fine or do I have to go for mulimode fiber cable?

2. My cable vendor says ... you have to use SC-LC single mode Duplex adapter=is it correct? as cisco 3750X / 2960S SFP module will be compatible with LC connectors=True?

3. What SFP module I have to order if I have to go for 1G or 4G fiber = SC or LC? confused?

4. My cable vendor says ...you have to use SC/PC Pigtail OS2 PVC 1.5 m  + SC to LC fiber connector...so what does he exactly mean by this?,,, &.. what I understood is...my 2960S switch connect as below:

Cisco2960--->SFP--->---LC connector--->----fiber---------> SC/PC Pigtail <----------fiber------------ LC connector---< ----Cisco3750X   ( pls correct if I am wrong anywhere)

5. As 3750X comes with 12 fiber ports + 4 extra modules ports so all my 6 switches(6X2=12ports = pls refer to the attached net-diagram) will get connected with each switch with redundant link but can i use 4 extra ports to connect my 2 physical server with this switch = if yes...what I have to use to get it connected?

3. For 1G, 1000BASE-LX/LH (GLC-LH-SM). 10G would be SFP-10G-LR

4. if you are connecting back to back and this is within the same room I would say save some money and go with a long patch cable to connect the two directly. If there is a room or a floor between the two devices I would recommend a patch panel so that you can make changes in the future. This will accommodate hardware changes and moves.

5. Yes, you should be able to, but you still need to match the SFP type, or more specifically the frequency.

The above would be straight answers without throwing you any curves. But here's a slight curve. If none of the closets are further apart than 300M, you may be better off going with 50um MM fiber (OM3 or OM4). It's not so much that the fiber will save you money, but the price difference in SFP's is huge when it comes to 10G

As of today, list price is:

SFP-10G-LR=  3,995.00 (Single Mode)

SFP-10G-SR= 1,495.00 (Multi Mode)

When you multiply that out by the minimum 12 SFP's (just to get to your switches) that's a big difference - 47,940.00 for SM versus 17,940 for MM.

Use the links below to see the specs for different types of Cisco optics. When I say that you need to match the "type", I really mean the frequency. Frequency usually equates to a "type" like LR, SR, LX, LH, etc. Please excuse my use of the word type when referring to SFP's as it can be misleading.

For example, Cisco SFP-10G-SR has a frequency of 850nm, and Cisco FET-10G also has a frequency of 850nm. They do not have the same name, and do not serve the exact same purpose (the purposes are for a completely different topic), but they are compatible to communicate with each other directly because the frequency matches. This is a common pairing when using Nexus switches.

I would be willing to bet that the server fiber cards run at 850nm which means the SFP-10G-SR would be compatible and can use any of the listed fiber types within the distance limitations.

Cisco 3750 ASIC Errors?

I have a stack of 2 Cisco 3750 WS-C3750X-24T-L Price switches and am attempting to rollout QoS in the entire LAN using the AutoQoS template. This has so far been a success on other 2900, 3700 and 4900 series switches, however this particular switch stack is not happy when we apply the commands.

This is what we see on the logging console when we apply AutoQoS globally or even just to 1 interface attached to an IP Phone:

We have swapped this stack with identical hardware using different stacking cables and we still see the same issue. These switches were purchased in batch.

TAC is the best idea for something like this.

Another thing to check is that the SDM templates match on all switches. If they don't match, autoQos can get screwy.

unstable iOS on 3750's

Catalyst WS-C3750X-12S-S is next-generation energy-efficient Layer 3 Fast Ethernet stackable switches while 3750X is layer 3 GE switches. The Cisco Catalyst 3750 v2 Series consumes less power than its predecessors 3750. The 3750-X Series Switches are enterprise-class lines of stackable and standalone switches with StackWise Plus technology, they are the replacement of Cisco 3750G and 3750E switches. 3Anetworkcom keeps many stocks for 3750V2 and 3750X switches. Among all Cisco Catalyst 3750 switches, WS-C3750V2-24TS-S and WS-C3750X-24T-S are best selling models. 3Anetwork.com offers best Cisco 3750 Price, Cisco 3750V2 Price, Cisco 3750X Price, ship to worldwide.

We've had issues with our 9 switch 3750 stack crashing on 12.2(58)SE2 so tac said to upgrade to 15.0(2)SE4. We did that upgrade today and while at first it seemed to take, the stack eventually froze and after a few reboots we just couldn't log in via ssh or console. Console would complain about memory.

So we eventually broke the stack and one by one downgraded to 12.2(55)SE8. Was a painful process as the last 3 switches are 3750X POE so they had to do the microcode update again. We also took out a 3750v2 48 port since we consolidated some things.

So now all seems working with 3 3750X PoE and 5 3750v2 on 12.2(55)SE8. downgrading to that version of IOS?

One of the best releases of IOS started from 12.2(55)SE6 to SE8.  I strongly recommend 12.2(55)SE8 as it's very stable.  All my 3750/G/E/X are running this version without any issues or even crashes.

15.0(2)SE4 is also not bad.  The rest are plain rubbish.

Cisco UCS FCoE Multihop Configuration

3Anetwork.com keeps regular stock of Cisco SFP-10G-SR, Cisco 10GBASE-SR Module SFP-10G-SR supports a link length of 26m on standard Fiber Distributed Data Interface (FDDI)-grade multimode fiber (MMF). Using 2000MHz*km MMF (OM3), up to 300m link lengths are possible. Using 4700MHz*km MMF (OM4), up to 400m link lengths are possible.

Cable up 2 additional twinax cables in each Fabric, doesn’t have to be twinax but that is the most cost effective way to go. You can also use 10G-SR SFPs and LC/LC fibre.

Configure an FCoE VLAN on Nexus:

This must be a new VLAN

Must be the same FCoE VLAN used in UCS for the current VSANs

Must only exist on the Nexus switch for which the VSAN is on. For example in the diagram above VLAN 100 only exists on Fabric A Nexus and VLAN 101 only exists on Fabric B Nexus.

Prune the FCoE VLANs from all trunks except for the FCoE port channels, this includes the vPC peer link.

Map the VLAN to the VSAN

Create a Virtual FC interface (vfc)

Add the vfc to the appropriate VSAN

Bind the vfc to the FCoE port channel

Two or more cables required for the NE020 (typically using SFP+ connectors)

Intel states support for Windows Server 2012 SMB Direct and Kernel-mode RDMA capabilities on the following adapter models:
