All LACP links are suspended

Graham Murison
Level 1
Level 1

I have configured an 4 interface etherchannel with a NetApp storage device.
This is the second bundle to the second controller of the NetApp device, the other one works fine with the same config.

I am getting all the interfaces with a status of suspended when trying force LACP (the only one supported by NetApp)
The stack in question are Catalyst 3650 running 03.06.05E


Here is the status of the enterchannel:
HQC4#sh etherchannel 2 summ
Flags: D - down P - bundled in port-channel
I - stand-alone s - suspended
H - Hot-standby (LACP only)
R - Layer3 S - Layer2
U - in use f - failed to allocate aggregator

M - not in use, minimum links not met
u - unsuitable for bundling
w - waiting to be aggregated
d - default port


Number of channel-groups in use: 3
Number of aggregators: 3

I have tried changing the "channel-group 2 mode" to on, however it is not able to detect the protocol:
HQC4#show etherchannel 2 detail
Group state = L2
Ports: 4 Maxports = 8
Port-channels: 1 Max Port-channels = 1
Protocol: -
Minimum Links: 0


Ports in the group:
-------------------
Port: Gi2/0/1
------------

Port state = Up Mstr In-Bndl
Channel group = 2 Mode = On Gcchange = -
Port-channel = Po2 GC = - Pseudo port-channel = Po2
Port index = 0 Load = 0x00 Protocol = -

Age of the port in the current state: 0d:00h:29m:39s

Port: Gi2/0/2
------------

Port state = Up Mstr In-Bndl


I am a complete loss and right now I am in NetApp failover mode. If this is a NetApp issue please let me know I and I will throw it their way!

 

Thanks.

So I thought I would update in case someone comes up with this issue or for those that really need to know.

I managed to find the resolution and document here.

 

The issue was that when a couple of storage nodes are setup in a HA cluster and you manually failover (say node B), then B will not send any LACP traffic over the bundled links.  In the older switch (C3560X) the physical links would remain active in standalone (individual) state.  With the new switches (C3650X), when this happens the links become suspended until manually unshut.

 

The resolution for my case is to set the command "no port-channel standalone-disable" on the port channel and now very is working as intended.  

 

Here is the resulting configuration:

interface GigabitEthernet2/0/1
switchport trunk allowed vlan 101,102
switchport mode trunk
channel-group 2 mode active
spanning-tree bpduguard enable
spanning-tree guard root
!
interface GigabitEthernet2/0/2
switchport trunk allowed vlan 101,102
switchport mode trunk
channel-group 2 mode active
spanning-tree bpduguard enable
spanning-tree guard root
!
interface Port-channel2
switchport trunk allowed vlan 101,102
switchport mode trunk
no port-channel standalone-disable
end

 I hope this may help someone else.

>...if this is a netapp issue....

  Well, indeed one thing to check is whether the interfaces on the 'second controller' are correctly configured and or are aware that they are to be used in a bundled mode. Compare with the interface configuration on the first controller (e.g.).

Well, maybe the problem is on the NetApp, check if configurations are correctly.

I hope that this documentation can help you: http://docs.netapp.com/ontap-9/index.jsp?topic=%2Fcom.netapp.doc.dot-cm-cmpr-910%2Fnetwork__port__ifgrp__create.html

If you using NetApp Ontab 7.X  on wards here is the sample working config.

 

Netapp Side :
vif create lacp <vif name> -b ip <interface list>

Cisco switch Side :

#channel-protocol lacp #channel-group X mode active

 Test and advise.

How to Ask The Cisco Community for Help

Thanks to all for the suggestions.  

Background:

We had two identical NetApp FAS 2000 series controllers connected to separate C3560X switches.  In the process of switching out these switch we installed a stack of two C3650X.  I managed to get the first controller head swung over to the new switch stack fine (all ports connected to switch #1 in the stack), the second is proving to be the problem child.

 

We have NetApp support, but didn't get far since nothing has changed on the controller end.  When I add the line channel-protocol lacp there is no change, still suspended with amber LEDs.  When I try channel-group 2 mode on without channel-protocol lacp the links come active (green), but LACP is not negotiated or sensed on the link.

When I try both channel-protocol lacp channel-group 2 mode on, the command is rejected: Command rejected (Channel protocol mismatch for interface Gi1/0/5 in group 2): the interface can not be added to the channel group.

 

I have also tried new network cables with ones I know are good, but the situation is the same.

 

If anyone has any suggestions that would be appreciated since I am now going to take the plunge with Cisco TAC.

 

Thanks,

Graham

 

 - Could you also have a test with passive-mode LACP on the switch side (as stated as-a-test).

Thanks.

Updated the config as follows:

interface GigabitEthernet2/0/1
switchport trunk allowed vlan 101,102
switchport mode trunk
switchport nonegotiate
channel-group 2 mode passive
spanning-tree bpduguard enable
spanning-tree guard root

This resulted in suspended links.

Okay I I am approaching this from a different direction by: shutting the interfaces, "Debug etherchannel all" and then "no shutdown" the interfaces.

It produces some surprising oputput, some of which includes pagp????

So confused.

So I thought I would update in case someone comes up with this issue or for those that really need to know.

I managed to find the resolution and document here.

 

The issue was that when a couple of storage nodes are setup in a HA cluster and you manually failover (say node B), then B will not send any LACP traffic over the bundled links.  In the older switch (C3560X) the physical links would remain active in standalone (individual) state.  With the new switches (C3650X), when this happens the links become suspended until manually unshut.

 

The resolution for my case is to set the command "no port-channel standalone-disable" on the port channel and now very is working as intended.  

 

Here is the resulting configuration:

interface GigabitEthernet2/0/1
switchport trunk allowed vlan 101,102
switchport mode trunk
channel-group 2 mode active
spanning-tree bpduguard enable
spanning-tree guard root
!
interface GigabitEthernet2/0/2
switchport trunk allowed vlan 101,102
switchport mode trunk
channel-group 2 mode active
spanning-tree bpduguard enable
spanning-tree guard root
!
interface Port-channel2
switchport trunk allowed vlan 101,102
switchport mode trunk
no port-channel standalone-disable
end

 I hope this may help someone else.
