Folks:I am having some sporadic performance issues between two 2960x switch, which are connected by a port-channel with 4 interfaces. Due to the latter, I am suspecting that one of my interfaces in the port-channel is causing the issue. How or is the...

Folks, I am having a hard time understanding some concepts I am reading about for Enterprise campus network design, more specifically the switch block design. On page 19 of the new SWITCH 300-115 Official Cert Guide details Figure 1-14, and shows t...

Folks:I am looking for a work around - Currently I have a four member 2960x switch stack - I have Ten 1/0/1 and Ten 3/0/1 in a port-channel; however, when I try to set the 'bandwidth' on PO1 interface to 20000000 I receive an error, which corresponds...

Switch is a 6513 and a HP switch is connected to the interface; however, I do not have access to this device to pull details... that is another department.

Hi Reza,one more question about "etherchannels" - can I think of 2x 10Gbps links bundled together as the following? 20Gbps throughput, but only 10Gbps of bandwidth? I am looking at it more from the STP issue that 'pille1234' - and STP will not see th...

Hi Pille1234,I think I am hitting a bug. The port channels are configured correctly, which I can verify via 'sh etherchannel summary' and 'cdp neighbors detail' ; however, my Po1 interface is only reading 10Gbps. Now, the odd part about it - my 6kvss...

Hi Reza,I was using poor choice of words - you following post "Portchannel does not increase the bandwidth, it just provides more lanes for you to use" - is how I understand it, so thank you for your professionalism and patience on explaining this. T...

HI Reza,Maybe I am looking at this the wrong. I understand the etherchannel group/interface is load balanced; however, wouldn't I still get 20Gbps in the aggregated PO1 interface since two 10Gbps links are bundled together? I am looking at this from ...
