They provide 24 or 48 Gigabit Ethernet wire rate ports, PoE/PoE+ support, and four 1G Small Form-Factor Pluggable (SFP) or two 10G SFP+ uplinks. With FlexStack-Plus technology, the Cisco Catalyst 2960-X switches can be stacked up to 8 members with up to 80 Gbps stacking capacity for high scalability. During this presentations, Roopa R. will talk about the architecture and stacking of the Cisco Catalyst 2960-X and 2960-XR Series Switches. She will also cover packet walk through, overview, configuration and troubleshooting of various features on these switches like QOS, Security, Netflow, PnP etc.

Why is it advised by Cisco not to use the switch with the uplink as stack master?­

There is no such restriction , not to use it. It is just possibly because if there is a master fail over, connectivity to the rest of the network would be lost. If you have redundant links, this should be fine to use the master uplink too.

Thanks,

There is no restriction. We would need to use a tar image for Auto upgrade.

Process of election is same, when a master is lost, member switch with highest priority, if the priority is same, switch with lowest mac address is elected as master

We are upgrading to 2960 XRs.

How many power supplies do we need for a 4 stack?

I think 2 on the top unit and 1 each on the other 3?

3 stack would be the same, 2 on the top unit and 1 each on the other 2?

Thanks,

Bill

Hi,

There is no restriction of power supplies for a stack, Stack can operate with all switches having single power supply, but if you want for a redundancy purpose, you can have two power supplies.

Thanks,

Hi Cisco Experts,

 

I have a problem, I am about to deploy 4 new Cisco 2960-X 24 Ports +POE but my 2 switch are encountering intermittent connection due to uplink / trunk ports facing core switch are experiencing auto-reset. I hope somebody can help me / enlighten me why is it only the 2 switches are experiencing auto-reset on trunk port(s) while the other 2 are okay, knowing that they all have the same configurations and using the same Lan connection to Core switch.

 

Best Regards,

Harley Acha

Not sure which image you are using on the 2960X. Can you please load 15.2(2)E8 and check if you see the issue? I think it is a known issue.

Thanks,

Roopa
