Re: OT: Nexus deployment with 802.3ad LACP team

Following is how i configured the vPC:

5K-A

vpc domain 1
  peer-keepalive destination 10.0.0.1

interface port-channel1
  switchport mode trunk
  vpc peer-link
  spanning-tree port type network
  speed 10000

interface port-channel10
  switchport access vlan 100
  vpc 10
  speed 1000

interface Ethernet1/17
  switchport mode trunk
  channel-group 1 mode active

interface Ethernet1/18
  switchport mode trunk
  channel-group 1 mode active

int e100/1/10
  switchport access vlan 100
  spanning-tree port type edge
  channel-group 10 mode active

This is the config on 5K-B:

vpc domain 1
  peer-keepalive destination 10.0.0.2

interface port-channel1
  switchport mode trunk
  vpc peer-link
  spanning-tree port type network

interface port-channel10
  switchport access vlan 100
  vpc 10
  speed 1000

interface Ethernet1/17
  switchport mode trunk
  channel-group 1 mode active

interface Ethernet1/18
  switchport mode trunk
  channel-group 1 mode active

interface Ethernet100/1/10
  switchport access vlan 100
  spanning-tree port type edge
  channel-group 10 mode active

sh vpc brief
Legend:
                (*) - local vPC is down, forwarding via vPC peer-link

vPC domain id : 1
Peer status : peer adjacency formed ok
vPC keep-alive status : peer is alive
Configuration consistency status: success
vPC role : secondary

vPC Peer-link status
---------------------------------------------------------------------
id Port Status Active vlans
-- ---- ------ --------------------------------------------------
1 Po1 up 1,14-15,100

vPC status
----------------------------------------------------------------------------
id Port Status Consistency Reason Active vlans
------ ----------- ------ ----------- -------------------------- -----------
100 Po100 up success success 100
114 Po114 down* failed Consistency Check Not -
                                      Performed

I dont understand why the status says down and the consistency says
failed. Please let me know if i configured something wrong or if i
need addition steps.

Thanks,
Usama
