Nexus 2K to Cisco 2960 IOS Switch
Hi,
I am trying to connect Nexus 2K FEX to Cisco 2960 IOS Switch (Trunk config) and causing spanning tree loop having issues. I am aware that I should't be connecting non host port to 2K FEX but it's corner case. I have done similar setup with Access Port configuration and didn't faced any issues.

Should I configure port as "spanning-tree port type network" and create VPC and "storm-control broadcast level" to stop future occurrence? OR Do i have to configure anything else to prevent spanning-tree loops?
Thanks for your help
RiteshHi,
spanning-tree port type network is used for VPC peer-link. Try creating a new VPC and add ports 107/1/47 and 108/1/47 to it and a Portchannel on the 2960 and test.

Hi all,
I wanted to know if there is a document or an article which describes 2960 series architecture specifically for model WS-C2960-24-S as there is for 2600 series in the following link:

You should be able to find the information that you need here:

Increasing TFTP block size for 2960 series switches
I have read that some Cisco components can increase the default TFTP block size to values greater than 512 bytes by using the command -
ip tftp blocksize xxxx
This doesn't seem to be available on Cisco 2960 series switches. Is there a way to do this with the 2960's?I have moved a WS-C2960-24LC-S running LanLite to 12.2(55)SE9 - the current end of the line for this switch - and indeed the command is not present. Sooo....this appears to be a limitation of LanLite.
My predecessor implemented about 70 switches with LanLite. I put a stop to this about a year ago but it is going to take some time to flush them out of the inventory.
Thanks for your response. -
Cisco 2960S SFF8472-5-THRESHOLD_VIOLATION
Hi All
I have a issue connecting my Cisco 3750X 12 port fibre switch to my Cisco 2960S 24Port switch using Multi Mode Fibre.
I have Mode condtioning cables connecting to the SFP (GLC-LH-SMD) on the 3750 via a fibre patch panel which bring me to the 2960s with its Mode conditioning cable and SFP (GLC-LH-SMD).
The fibre port on the Cisco 2960S was up for all of 10 mins and has gone out with the following error message.
%SFF8472-5-THRESHOLD_VIOLATION: Gi1/0/26: Rx power high warning; Operating value: -2.7 dBm, Threshold value: -3.0 dBm.
I did a show int transceiver command and got the following output.
DS-THN-SW3#show interfaces transceiver
If device is externally calibrated, only calibrated values are printed.
++ : high alarm, + : high warning, - : low warning, -- : low alarm.
NA or N/A: not applicable, Tx: transmit, Rx: receive.

All SFP's are new as is the Multi Mode Fibre cable running from one building to another.Hi All,
One of member port of port channel was flapping and Here is the error message

Cisco TAC analyse the issue under 629566213 but their initial advices was not much experience oriented.
Finally I have resolved the issue just by entering following command.

Cisco 2960S Configured in Transparent mode
I have a Cisco 2960S gig switch configured in transparent mode with multiple vlans configured. I have printers that I can ping, the ports shows up but on the printer it says offline. Any idea what could be causing this?
If your printer and your PCs are all in the same subnet and only the printer is not working then VTP mode Transparent has nothing to do with your issue.
I'd be keen to know if you have a firewall blocking anything from the IP address of the printer? Maybe the IP subnet mask or default gateway of the printer is not working?
What do you get when you do a "sh mac-address interface <PRINTER port>"? -
Low Transfer Rate On 2960-S Switch
Hi,
I have 2 PCs (1gbps lan card each ) connected to Cisco 2960-S switch.
The bandwidth of all ports on 2960-S is set to 1gbps manually.
However whenever I transfer any file between the two I don't get transfer rate more than 12MBps/96mbps.
Theoretically it should be 125MBps but why am I getting such low transfer rate?

Cisco 2960S FPS-L PoE switch with Avaya 9811g VOIP setup
Hello,
I am connecting a setup for data/voice connecting Catalyst 2960S-FPS-L PoE switch with Avaya 9811g series VOIP phone. As per my knowledge cisco switch works well with Cisco phone as it has got some builtin "Macros" and Intelligent PoE recognition when we connect device getting the details of another device through CDP. I understand I have to create data and voice vlan with QOS then enable trunking on the interface to other switch that is also 2960. Little confuse if is there any compatibility issues with Switch and Avaya phone regarding protocol/data/voice...?
Do I have to do PoE config for each port on the each interface?
any help or detail config will help.
Thanks in advance.Hi I am back after good research. created two vlan data and voice with trunk on interface1/0/48 given below config..
connection b/w 2960s FPS Switch and Avaya 9611g IP Phone.
lldp/cdp is enable on switch
So I created this config if some one can take a look .
expert advise if something wrong?..
I am only concern with Voice and PoE as voice is my priority. do i have to map something for voice quality?
also if i create another Trunk port one allow voice other allow data both cable will go to switch will that be issue?

How to connet cisco 2960S switch to sony nexus 7?
I want to buy an cisco WS-C2960S-24TS-S switch to help me solve business networking problem. Can someone help me to connect cisco 2960s switch to nexus 7 ?
I don't need to do anything config on the new switch, I just need to upgrade the new switch's IOS version as the existing stack.
Correct. Upgrade using the command "archive download-sw" instead copying the BIN files.
After doing above task, I connect all stack cable and power cord as you said, and then the new switch can be synchronized with the MASTER switch. right??
Correct. The new switch should NOT have any configuration. This includes VLAN.dat file. -
