Nexus 7010 Fex Port-Channel

Hallo All , 

 

we are using Nexus 7010 (having 4Port group) with the following inventory and three fex are attached with ProdcutionVDC by using 3 port-channel(4xPorts) with each module( 1/1-4, 2/1-4, 3/1-4) respectively. 

 

Could we configure these port-channel by using 2  ports from each module (like 1/1-2 or  2/1-2 or  3/1-2) for redundancy purposes for each fex. 

 

Secondly could we also configure access port-channels by taking ports from different modules for redundancy purposes.  

 

Thanks in advance for feedback.

Yes that is way moving forward for redundancy purpose, either you can use different ASIC or different Line cards.

 

"Secondly could we also configure access port-channels by taking ports from different modules for redundancy purposes.  "

 

you mean to say FEX ? if not explain more.

Re: Nexus 7010 Fex Port-Channel

Thanks balaji. 

 

How could we use with asic , you mean to say port-group or what , please guide me . 

 

 

Secondly by using Fex ports could we use like these two interfaces for one port-channel attached with Server.

 

interface eth102/1/44 and  interface eth104/1/44

Regards

Re: Nexus 7010 Fex Port-Channel

Here is the details about ASIC.

A switch is a layer 2 device that makes a decision based on the layer 2 frame destination MAC address. The more ports you add to a switch the more processing a switch is doing. Just a few ports can be handled by software written to run on an off-the-shelf CPU. As the number of switch ports increase, the general purpose CPU using software solution can't keep up. The ASIC is basically a CPU that is not a general purpose CPU but is a CPU for making switching decisions very quickly. It can't be used for much else. This is similar to a high-end graphics card that has a special CPU for graphics processing that wouldn't be good for general applications. Hence the name, Application Specific Integrated Circuit.

different ASIC can be used generally in case where you do not have redundant line cards to use to hardware fail case.

 

 

interface eth102/1/44 and  interface eth104/1/44

yes this is possible to use with Server.( configure server side also bundle).
