Alteon Switch to Cisco 2960 port aggrigating

LACP / 802.3ad is required to aggrigate a cisco to a non cisco switch, is there any issues connecting a Cisco 2960 to a Alteon Switch.

There should be none as long as alteon support LaCP, 2960 certainly do. for configuration guide info, have a look at the following:

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
Ritesh

Hi,
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.

Configuring Port Channel on Cisco 2960S-48LPS-L

When I try to move port channel connections to two of the SFP ports on our Cisco 2960S switch, one of the connections fail.
I am using two GBics, both are the same, GLC-T-A 1000Base-T.
The port channel work fine when I use g1/0/47 and 48.
The port channel work fine when using g1/0/48 and SFP 1/0/49

Cisco 2960S-24TS-S using SFP modules between switches

I am using Cisco 2960S-24TS-S using SFP modules for two different speed requirements, I have two SFP ports using 100Mbit modules and the other two SFP ports using 1000Mbit modules.
I have two Cisco 2960S-24TS-S switches connected together via a fiber optic cable, and each SFP module is on port 28, with a 1000 Mbit SFP module in each, and the two switches will not connect. The fiber was checked with a light tester not a db kit.
Do I need to have SFP port specific setup details in a configuration file for the Cisco Switch or does the SFP module handle this?
" interface GigabitEthernet1/0/28" - set up in config file for the port. Does this need to dictate "interface 100" or "1000MbitEthernet1/0/28" instead?

The ports should auto-negotiate speed you should not need to hard code them to get them to come up , Are the ports showing up/down or down/down can you post the show interface for each side and the show run int x/x for each port

Power up cisco 2960 switch with 12V DC Power

hi all ,
I have some issue with supply power to cisco 2960-24TT-L switch. In my server farm rack is having DC current of -48V. But however cisco switch require 12V DC current.
Cisco Spec.

Cisco 5 port and 8 port gigabit unmanaged switches

I am looking for 5 port and 8 port gigabit unmanaged switches in Cisco. Please provide the BoM for the same. As per my understanding the following switches can suffice the requirement (SG100D-05 and SG100D-080) however I am not sure about the DC power, whether they can be used in normal AC environments.

The SG100D-05 and SG100D-08 are too small and their power requirements are too low to justify building an AC power supply into them like the larger SGx00 switches have, so they are wired to accept DC power and use an external power adapter (included) for connection to an AC environment.
There are really no optional components to these devices, so the BOM would be as follows:
5-port SG100D swich: SG100D-05
8-port SG100D swich: SG100D-08

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.

Cisco 2960s Switch replacement

Greetings,
Dear Experts,
We are using the Cisco 2960s Switches in our network. We have two failed switches and asked for replacement from our supplier. They informed that the 2960s model is approaching End Of Service (EOS) and the replacement of that model are as below:
1- WS-C2960X-24TS-L
Catalyst 2960-X 24 GigE, 4 x 1G SFP, LAN Base
2-WS-C2960S-24TS-L
Catalyst 2960S 24 GigE, 4 x SFP LAN Base
What is the best practice to make my decision of which to select? will it make difference from the configuration perspective? is there a possibility for conflict with the existing 2960s Switches?
Many thanks in advance for your kind assistance.
Thanks and Regards

We have two failed switches and asked for replacement from our supplier.
Time for you to talk to your supplier. Cisco has announced the EoS/EoL for the 2960S back in November 2014 (End-of-Sale and End-of-Life Announcement for the Cisco Catalyst 2960-S Series and 2960-SF Series Switches). However, this only means the date of November 2014 is just a date of announcement. The final date of sale for the 2960S is November 2015.
I think your supplier either is getting confused (didn't read the announcement properly or didn't know) or is just looking for ways to make more money.
is there a possibility for conflict with the existing 2960s Switches?
You can form a stack of 2960S and 2960X. Just know the limitations, and they are:
1. The entire stack must have the same IOS versions;
2. The stack speed will drop from 20 Gbps (2960X) to 10 Gbps because 2960S has been set to run only at this speed; and
3. You cannot have five or more in a stack if you have a 2960S as a member of the stack.

Airport Extreme dropping connection with a Cisco 5 port Giga switch

I've connected a Cisco 5 port Giga switch SG100D-05 to one of the LAN ports of the Airport Extreme and for some reason the connection is being dropped or it fails to connect. Any idea of why this is happening and how can it be fixed?

If you have not already done so, you might want to do some basic troubleshooting to try to isolate the cause of the issue.
To do that, temporarily disconnect the switch and power it off. Connect a computer with an Ethernet port on it to the LAN port on AirPort Extreme and turn off the wireless on the computer.
Test to see you can get a good Internet connection this way.
If you can, then you know that the LAN port on the AirPort Extreme is functioning correctly and your troubleshooting efforts will need to focus on testing each port on the Cisco switch.
If you cannot get a good connection with the computer connected directly to the AirPort Extreme, try another Ethernet cable that you know is working to eliminate the possibility of a bad Ethernet cable, which is the culprit more often than you might think.
Please post back on the results of your testing.
