I was looking at WS-C2960S-48FPS-L (740 Watts) and WS-C2960S-48LPS-L (340 Watts) models today, I'm not sure that I understand it right,
Does WS-C2960S-48FPS-L model support all 48 ports POE+ (30Watts)? Does that mean each port will get 30 Watts on this switch?
Does model WS-C2960S-48LPS-L support 24 ports with POE and 24 ports with POE+?.
I'm trying to configure a stack between two WS-C2960S-48FPS-L but does not working.The switch port is always Down.I tried to change de module and cables.I tried to make a loop in one of two switches and the ports always down.
IOS: 12.2(55)SE5
#show switch stack-ports

The pinout of poe and poe+ (802.3af) and (803.3at) of these models of Cisco switches?
WS-C2960S-48FPS-L 48 Ethernet 10/100/1000 PoE+ ports; 740W PoE capacityWS-C2960S-48LPS-L 48 Ethernet 10/100/1000 PoE+ ports; 370W PoE capacityWS-C3750-48PS-S 48 Ethernet 10/100 ports with IEEE 802.3af and Cisco prestandard Power

How many Switches can be stacked with WS-C2960S-48FPD-L at a max..
As per my Knowledge it is 4 and as below..
Switch 1 to Switch 2
Switch 2 to Switch 3
Switch 3 to Switch 4
Switch 4 to Switch 1
If yes then, is it mandatory to do the "Switch 4 to Switch 1" stack. why am I asking this is because this stack requires a long cable and the cable which comes with the Switch is only 0.5M.
My company is beginning to have a lot of sites were we are stacking 3 to 4 C2960S-48 switche.This is making "show running-config" very very long because of the 4 x 48 interfaces.I can’t find a CLI command that show me the running-config of a ranges of interfaces. If I for example would like to see running-config for switch 3 (interfaces 3/0/1-52)The Show Running-config will show all the interfaces (for the two first swtiche = 104 interfaces), which take a time before I reach to switch 3.I miss a CLI command like: show Running-config switch 3, or module 3, or show running-config interface range x/x/x-x ?I’m well aware of the CLI command show running-config interface x/x/x, but this will only show me one interface.

Note that the fiber optic that we have coming from filed are multimode.
View 2 Replies View RelatedOur network administrator restricts all our new 1Gb switches to only 100Mb, to which he claims it will increase overall performance. Preventing devices from bottlenecking the network. (that is, only restricting the main switch ports, not the uplinks)For example we have a new building with 2x WS-C2960S-48TS-L connected together with FlexJack and then a 1Gb Fiber connection back to our core switch.
This building is on it's own subnet and there is little broadcast traffic. I don't see the point other than it hinders the potential speed we could use. Labs are set up in this building and 1Gb is MUCH faster when it comes to imaging and software deployment.
I am currently using catalyst 4506 L3 switch and 2950 L2 switches for pc's which are EOL. I am replacing L3 with 3750X, two switches in a stack. L2 is 2960S all with gbps ports. I have to have a baseline (performance comparison with the current setup and new setup) and I am using the following methods
1. Iperf throughput comparison among local vlans
2. Iperf throughput comparison with remote data centers servers.
3. Ping/ftp upload/download comparison with remote DC's. FTP file is around 3GB.
Today I have tested the above with the new setup and compared it with the old setup. For the tasks 1 & 3 I found better performance with the new setup. However the task 2 did not show any performance increase infact the throughput was much lower comparing to the old setup.
I just upgraded several of my C2960S-48FPD-L from 12.2(55)SE to 12.2(58)SE and now almost every time I try to SSH to it the switch reboots and gives me these trace backs ...

I am looking for a reasonable switch but it has do do inter-VLAN Routing. I know I could go with a 3560/3750 with IP Services but I am also thinking the 2960S with IP Base IOS might do?
I have looked up the IP Base IOS and it does list IP Routing but how to actually configure inter-VLAN Routing on a 2960S with IP Base?
I have been trying to enable L3 intervlan routing on C2960S Switch with ip routing command and that was the output from the Switch: [code]

I have a customer with a stack of two switches C2960S-24TS-L that are running 12.2(58)SE2 universal K9, we see that the CPU load increase over time, to 95% and stays there reload solves the problem.the process that akes a lot of CPU is also the SNMP ENGINE, I see that it is running 30 minutes on 95% and then 10 minutes on 35%, this is the only stack were we see this problem. Is there also a SNMP bug in this version ?

Can I use the above said switch for 1 Gig Uplinks using SFP.
I have three new 2960 switches as listed in the title. I configured them as follows:
192.168.1.215 host: whse-c
192.168.1.216 host: whse-b
192.168.1.217 host: whse-a
Switches B and C flow into A before continuing on into the server room switch (distance issues).All three switches are configured for ports 21-24 at 1000 and set as cisco switches. all other ports are undefined as they have a myriad of desktops, printers and non cisco access points flowing into them. side question - should i configure them as access points where applicable even if they are non cisco? I am replacing three netgear switches that currently are in place and have no known issues other than they are old and the fans may fail soon.hooked up .217. was able to get to it from the network. Hooked up 215 and then 216. All the sudden I lost the ability to tap into the switches, any of them. (I think I had done 215 at that point too, before adding 216. I found out later it took the network to its knees as internet was lost, and the MPLS stopped functioning.
I undid the changes and put the netgears back in service and all was right with the world again. At first I thought it was a bad host name as I had used whse-a on switch C in error. I changed that after this issue.Later that day I put 215 in place. checked it from the network and could get to it just fine. Then I put 216 in service. I lost connection to 215. I could no longer get to the internet from my pc and the MPLS went down again. This time I just unhooked 216. 215 is still in place and working on the network at the moment and not causing issues. (btw these switches are not even in my path from my pc to the internet, just on the same network) tomorrow I am going to try 217 again while 215 is still on the network and see if there are any issues adding that swtich. if I can do so, and there are no problems, is this an indication of a faulty switch? what further testing can I do, have I missed something in setup? If this brings the network down again, why cant i add two of these switches to each other/on the same network path (B and C were not even connected to each other yesterday evening when it went down again).
I have a got a requirement where a 24 Port Switch should have 4 SFP's and all 4 should be used at a time, So I've chosen " WS-C2960S-24TS-L"
The transeiver should be GLC-LH-SM, so kindly let me no whether I would be able to use all 4 ports at a time or not.
I have configured about 20 of these switches now, and notice in the port listings a TE1/1//1 TE1/1/2 and GI1/1/1 GI1/1/2 uplink port. There are only two uplink SFP+ ports. I now have a reason to install with a 1Gb uplink to the Core. I am using a GLC-LH module at each end. I did configure the TE1/1/1 port for the uplink. Does not work though..Do I need to configure the two GI1/1/1 and 1/1/2 ports for uplink, remove the TE configuration for the uplink to work? Using the UNIVERSAL code with a LANBase license.

I have a stack of 4 Cisco WS-C2960S-48FPS-L switches running c2960s-universalk9-mz.122-58.SE1 code. One of our network monitoring tools is indicating discards on a certain port on the switch. Upon further investigation I am seeing the Total output drops values change in a very odd manner.
The numbers seem to go from 573 to 1146 to 1719 then back down to 573 and it starts the same pattern over: [code]
The port utilization is quite low, the highest I've seen over the past 7 days is 3.5% with a polling period of every 30 seconds using Statseeker. Yet the discards are bouncing all over the place.
