VPC+ configuration example

Below is the VPC+ configuration example.

VPC+ is configured between N5k-1 and N5k-2 where fabric path is configured on the VPC peer-link. We assume that Teaming is properly configured on the server end and hence only switch side configuration is demonstrated here.

N7K-1:-

Install feature-set fabricpath  //--<<<< It must be executed in Default or Admin VDC //

feature-set fabricpath

feature lacp

fabricpath switch-id 71  //--<< To configure Static switch-id otherwise it will be dynamically assigned//

vlan 100

  mode fabricpath

interface Ethernet1/1

  switchport mode fabricpath

interface Ethernet1/3

  switchport mode fabricpath

interface Ethernet1/4

  switchport mode fabricpath

N7K-2 :-

Install feature-set fabricpath

feature-set fabricpath

feature lacp

fabricpath switch-id 72

vlan 100

  mode fabricpath

interface Ethernet1/1

  switchport mode fabricpath

interface Ethernet1/3

  switchport mode fabricpath

interface Ethernet1/4

  switchport mode fabricpath

N5K-1 :-

Install feature-set fabricpath

feature-set fabricpath

feature Lacp

feature vpc

fabricpath switch-id 51

vpc domain 100

 peer-keepalive destination 10.1.1.52

  fabricpath switch-id 55  //----<<<<<<<<<<<< Must be configured for VPC+ //

vlan 100

  mode fabricpath

interface Ethernet1/1

  Channel-group 1 mode active

  switchport mode fabricpath

interface Ethernet1/2

  Channel-group 1 mode active

  switchport mode fabricpath

interface port-channel1

  switchport mode fabricpath

  VPC peer-link

interface Ethernet1/3

  switchport mode fabricpath

interface Ethernet1/4

  switchport mode fabricpath

interface Ethernet1/5

Channel-group 2000 mode active

  switchport mode trunk

int po2000

switchport mode trunk

vpc 2000

no shut

N5K-2 :-

install feature-set fabricpath

feature-set fabricpath

feature lacp

feature vpc

fabricpath switch-id 52

vlan 100

mode fabricpath

vpc domain 100

 peer-keepalive destination 10.1.1.51

  fabricpath switch-id 55

Note:- If you missed to configure sub switch-id under VPC domain then VPC peer-link will remain down.

interface Ethernet1/1

Channel-group 1 mode active

 switchport mode fabricpath

interface Ethernet1/2

Channel-group 1 mode active

switchport mode fabricpath

interface port-channel1

  switchport mode fabricpath

  VPC peer-link

interface Ethernet1/3

switchport mode fabricpath

interface Ethernet1/4

  switchport mode fabricpath

interface Ethernet1/5

 Channel-group 2000 mode active

  switchport mode trunk

int po2000

switchport mode trunk

vpc 2000

no shut

Verification:-  

1. Show fabricpath switch-id

N7K-1# show fabricpath switch-id                         FABRICPATH SWITCH-ID TABLE Legend: '*' - this system ========================================================================= SWITCH-ID      SYSTEM-ID       FLAGS         STATE    STATIC  EMULATED ----------+----------------+------------+-----------+-------------------- 51          0005.73bd.fabc    Primary     Confirmed     Yes     No 52          0005.73bf.337c    Primary     Confirmed     Yes     No 55          0005.73bd.fabc    Primary     Confirmed     No      Yes 55          0005.73bf.337c    Primary     Confirmed     No      Yes *71          0026.980d.4143    Primary     Confirmed    Yes     No 72          0026.980d.3c43    Primary     Confirmed     Yes     No

2. Show fabricpath isis adjacency
