some N2K model not available on provision model

[guillerm]

Hello,

We need to replace old Nexus 5020 (NX-OS 5.2.1) by Nexus 5596 (NX-OS 7.0.5)

We are trying to use the "provision model" command in the target N5596 config in order to pre-provision the N2Ks currently connected on the N5020;

The problem is that none of the 2 N2K models (visible via show fex on N5020) is accepted on this "provision model" command :

1) Extact of "show interface fex-fabric" on current old N5020 :

N5020# sh interface fex-fabric
     Fabric      Fabric       Fex                FEX
Fex  Port      Port State    Uplink    Model         Serial
---------------------------------------------------------------
110    Eth1/1        Active     2    N2K-C2248TP-1GE  xxxxxxxxxxx
111    Eth1/2        Active     2    N2K-C2224TP-1GE  xxxxxxxxxxx

2) results of "provision model" command on new N5596 :

N5596(config-slot)#   provision model N2K-C2248TP-1GE
                                                             ^
% Invalid parameter detected at '^' marker.

N5596(config-slot)# provision model N2K-C2248T?
N2K-C2248T          N2K-C2248TP-E-1GE          N2K-C2348TQ

N5596(config-slot)#   provision model N2K-C2224TP-1GE
                                                             ^
% Invalid parameter detected at '^' marker.

N5596(config-slot)# provision model N2K-C2224T?

N5596(config-slot)#

So, as the 2 existing N2K models were not available on "provision model" command, we chose the 2 following models :

slot 110
  provision model N2K-C2248TP-E-1GE
slot 111
  provision model N2K-N2224TP

We also checked the NX-OS 7.0.5 Release Notes and our 2 existing N2K models are supported on N5596 ;

Question :

Can these model differences cause a problem when we move the existing N2K from N5020 to the new N5596 ? 

thanks for any feedback

Yeah

I just tested on one of my box which is quite old version:0-  system:    version 5.2(1)N1(4)

and i see all the models there:-

switch(config-slot)# provision model ?
  N2K-B22DELL         Fabric Extender 16x10G Module
  N2K-B22FJ           Fabric Extender 16x10G Module

  N2K-C2232TM-E-10GE  Fabric Extender 32x10G Module
  N2K-C2248T          Fabric Extender 48x1G 4x10G Module
  N2K-C2248TP-E-1GE   Fabric Extender 48x1G 4x10G Module
  N2K-N2224TP         Fabric Extender 24x1G 2x10G SFP+ Module
  N55-M12T            Cisco 12x10GBase-T Ethernet Expansion Module
  N55-M16FP           Cisco 16 port Port Fiber Channel Expansion Module 16 x
                      SFP
  N55-M16P            Cisco 16x10G Ethernet Expansion Module
  N55-M16UP           Cisco 16x10G Flexible Ethernet Expansion Module
  N55-M4EP40G         Cisco 4x40G Ethernet Expansion Module
  N55-M8P8FP          Cisco 8 Port 1/2/4/8G FC + 8 Port 10G Ethernet Expansion
                      Module
  N5K-M1008           Cisco 8 Port Fiber Channel Expansion Module 8 x SFP
  N5K-M1060           Cisco 6 Port Fiber Channel Expansion Module 6 x SFP
  N5K-M1404           Expansion Module 4 x 10GBase-T LAN, 4 x Fiber Channel
  N5K-M1600           Cisco 6-port 10 Gigabit Ethernet SFP Module 6 x SFP

Now two options I need to upgrade to the latest one and check for you or you can downgrade and see if it works for you?

Hello guillerm,

Looks like you are hitting bug CSCtl59996. 

provision model N2K-C2224TP

CSCtl59996

Symptom:
not able to use the command provision model N2K-C2224TP
Conditions:
try to pre-provision a N2K-C2224TP
Workaround:
do not pre-provision this model

"Can these model differeences cause a problem when we move the existing N2K from N5020 to the new N5596?"

Not sure.  Maybe someone else will chime in that can answer that question.

I believe "N2K-C2248T" is the variant you want to use, at least that is the model I used for exactly the same purpose and it worked without a problem.

well; you were right, I was able to do a test with 2 N2K and it works by coding :

slot 110

provision model N2K-C2248T

slot 111

provision model N2K-N2224TP

the 2 FEX were correctly recognized as the right models after connecting to the 2N5596 as shown via the following show fex :

N5596# sh interface fex-fabric
     Fabric      Fabric       Fex       FEX           Fex
Fex  Port      Port State    Uplink    Model         Serial
---------------------------------------------------------------
110    Eth1/1        Active     2       N2K-C2248TP-1GE   xxxxxxxxxx
111    Eth1/2        Active     1       N2K-C2224TP-1GE   xxxxxxxxxx

thanks to all for their feedback
