Cisco MDS 9148 port aggregation bandwidth output via port channeling.

Ashish Kumar

Hi guys,

I want to test the aggregation bandwidth on the MDS 9148, How can we do it?

 

I tried to do it via below command:

In Config mode:

feature fport-channel-trunk

Feature npv
 

Switch A-


 interface port-channel 10
   channel mode active
   switchport mode NP
   switchport trunk allowed vsan 1
   switchport rate-mode dedicated
   switchport trunk mode on
 
 interface fc1/1-2
   switchport mode NP
   switchport trunk mode on
   port-license acquire
   channel-group 10 force
   no shutdown

But my port is not showing me bundled speed, as expected 16 Gbps, because one having 8 Gbps bandwidth.

 

 

Thanks

Ashish

Are you connecting this MDS 9148 (NPV mode) to another switch, running in NPIV mode ?

Can you please post output of "show interface fc 1/1 - 2" and port-channel 10....

hi walter,

We want to test port aggregation. So we are trying to port channeling with 4 port and will show the client 4x8 Gbps =32Gbps output.

Following this document.

http://www.cisco.com/c/en/us/td/docs/switches/datacenter/mds9000/sw/5_2/configuration/guides/int/nx-os/cli_interfaces/pc.html#97250

 

Will share you soon port details.

 

Thanks

Hi Ashish

I hope we talk about the same ? there is E PortChannels and F and TF PortChannels !

We talk about F and TF PortChannels !

Note If a Cisco MDS 9124 or 9134 switch is used as a core switch, only a nontrunking F PortChannel is supported. Trunking is not supported on this platform when NPIV enabled.

That's why I asked you what kind of switch is running NPIV ?

Walter.

Hi Walter,

Thanks for your support. 

I done it today after port channeling with 8 port with single port-channel.

and we get the output 64Gbps as below output.
