Nexus 5548UP vPC configuration

Kevin Martin

Level 1

I have followed every piece of cisco documentation I could find on this and I still can't get vPC configured to actually work.  The VLANs stay in a suspended state so no traffic flows across.  Below is my configuration:

vrf context management
  ip route 0.0.0.0/0 10.86.0.1
vlan 1


vlan 86
  name I.S_Infrastructure


vpc domain 1
  role priority 1000
  peer-keepalive destination 10.86.0.4

interface Vlan1

interface Vlan86
  no shutdown
  description I.S._Infrastructure
  ip address 10.86.0.1/24

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

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

interface Ethernet1/2
  switchport mode trunk
  channel-group 1 mode active

interface Ethernet1/3

  description Connection to Mgmt0
  switchport access vlan 86
  speed 1000

interface mgmt0

  ip address 10.86.0.3/24

This change this to "spanning-tree port type network"

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

Let me know, if that resolve your issue.

Thanks

Still nothing.  When I remove the vPC configuration and just use the port channel to trunk the vlans, both 5k's can see each other.  Once I put the vPC config on I get nothing. 

switch# show vpc
Legend:
                (*) - local vPC is down, forwarding via vPC peer-link

vPC domain id                   : 1
Peer status                     : peer link is down
                                  (peer-keepalive not operational,
                                  peer never alive)
vPC keep-alive status           : Suspended (Destination IP not reachable)
Configuration consistency status: failed
Per-vlan consistency status     : success
Configuration consistency reason: Consistency Check Not Performed
Type-2 consistency reason       : Consistency Check Not Performed
vPC role                        : none established
Number of vPCs configured       : 0
Peer Gateway                    : Disabled
Dual-active excluded VLANs      : -
Graceful Consistency Check      : Disabled (due to peer configuration)

Assign the port-channel1 to vrf "management"

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

  vrf memeber management

let me know.

thanks

Hello rizwanr74

These commands that you suggest are disruptive ?  they mean any big impact inside the nexus ?

I don't see the command "vrf member management" under my port channel.  I do see it under mgmt0 but that had no affect on my problem.

Beside the peer-link is using the wrong port type (should be network). The other problem is the peer keepalive is not up:

Peer status:     peer link is down (peer-keepalive not operational, peer never alive)

Can you ping 10.86.0.4 vrf management?

Thanks for the help everyone.  Since this is new to me, I didn't know I couldn't plug the mgmt0 interface back into the 5548 and expect it to talk...So i used an external switch to provide communicaiton for mgmt0.  That solved the whole problem.
