LACP randomly fail between hpe5700 and cisco 6509

[lozair31]

Hi,

we encounter here a LACP problem between two devices, this LACP is constructed with two Ten Gigabit interfaces on each side. :

• HPE5700-32XGT-8XG-2QSFP+ (interfacename =Bridgeaggregation33 [ XGE1/0/33 + XGE2/0/33 ])
• Cisco 6509 (interfacename=Po14 [ Te1/3 + Te3/3 ]).

Randomly, once a week, the Cisco 6509 set PortChannel 14 in errdisabled state and cut the link to the HPE5700 with the following message :

CET: %PM-SPSTBY-4-ERR_DISABLE: channel-misconfig error detected on Te1/3, putting Te1/3 in err-disable state
CET: %PM-SPSTBY-4-ERR_DISABLE: channel-misconfig error detected on Te3/3, putting Te3/3 in err-disable state
%PM-SPSTBY-4-ERR_DISABLE: channel-misconfig error detected on Po14, putting Te1/3 in err-disable state

On the same time these logs appears on HPE5700 :

<190>Dec  3 02:33:59 2016 SWITCH %%10LAGG/6/LAGG_INACTIVE_CONFIGURATION: Member port XGE1/0/33 of aggregation group BAGG33 changed to the inactive state, because the aggregation configuration of the port is incorrect.

<187>Dec  3 02:34:00 2016 SWITCH %%10IFNET/3/PHY_UPDOWN: Bridge-Aggregation33 link status is down.
<189>Dec  3 02:34:00 2016 SWITCH %%10IFNET/5/LINK_UPDOWN: Line protocol on the interface Bridge-Aggregation33 is down.

Reading the logs, it seems there is an event on HPE5700 around bridge aggregation 33 port members. This event seems produce the err-disable protection on the cisco side..After five minutes the Cisco leave the err-disable state on the portchannel 14 and all works like a charm...

.We have read the docs and guides about LACP but we can't identify the reason of this random event on the HPE5700. I want precise there is no errors on the links between cisco and HP.

We use the following configuratoin on the HP :

Thanks for your help or advices

hello

shall you post firmware versions for both please

thanks

[Vince-Whirlwind]

What if you use link aggregation-mode static instead of dynamic?

Hope this can help

[lozair31]

We don't test it.

This link join network core router to our server switch stack.......

Do you think this can resolve the issue ?

[parnassus]

What is the display link-aggregation verbose command's output on the HPE 5700?

Mumble Mumble...you cited stack ("This link join network core router to our server switch stack......."), do you have an IRF Stack of HPE 5700 units or just a single HPE 5700 Switch?

[peyrache]

should be great to be in Static in both side if problem still occured

debug lacp on cisco side witl help to get more details

We will attempt this config if the error come again

thks for your advice

[VoIP-Buddy]

The only gotcha with static link-agg is that the links never go down.  If something happens, you'll be sending packets into a abyss.

I would debug lacp on the 5700's as well to see what is causing this event.

You might also want to check Spanning Tree, if it is enabled, to see if one of the ports is blocked.

David

[lozair31]

thks for the reply

i can't enable debug lacp on 5700...

no more information, is there specific command to get debug events sent to syslog like other events on hp5700 ?

same at cisco level i had enable debugging lacp events and error but no more results...

we think about set the cisco in LACP passive mode and kept hp5700 in LACP active mode but i don't know if that can have an effect on our problem..

[VoIP-Buddy]

Hi!

Use this command...  > debug link-aggregation lacp packet  You can then choose all, send, or receive.
If you are sending debug to syslog you should be all set.  That is done in the information-center.

Regards,

David

This may help, it may not.  Attached is the pertinent config from our 3Com XRN switch stack doing EtherChannel with our Cisco 6509E VSS cluster.  Comware version 3.03.02s168p23, Cisco IOS version 15.1(1)SY.

[lozair31]

thanks for your reply...

it seems we are running the same config here.....

[lozair31]

thanks for the information

We have enabled the debug en we get logs about lacp on our syslog server.

It seems the cisco break the link but i'm not sure about that

attached logs from H3C 5700 with lacp debug activated.

It seems the H3c stack receive lacp information (FSM.RX) from cisco saying " i disable the port" :

02:31:56 2016 sw-csn-srv %%10LAGG/7/Fsm: -Slot=2; Ten-GigabitEthernet2/0/33 FSM.RX CURRENT-->PORT_DISABLED, Port_Disabled
02:31:57 2016 sw-csn-srv %%10LAGG/7/Fsm: Ten-GigabitEthernet1/0/33 FSM.RX CURRENT-->PORT_DISABLED, Port_Disabled

That seems indicate that it's the cisco wich cut the link.....

I can't enable lacp debug on 6509, the debug lacp command seems not exist on our Cisco OS

[peyrache]

hi

this configuration did ever worked or always experimented this issue ?

what are cisco version ?

JY

[peyrache]

shall you post

show tech from cisco device please

JY

[lozair31]

this configuration is up since 3 months now and we encounter this random problem immediately after we setup this

but this problem seems to be linked to event on the network.....

This problem occur randomly once a week.

we have this link down mostly at the same time range, approximatively 2:30 AM

Hi

I can't publish all the conf of our cisco......

reading show tech or show diags there is no physical errors on the links.

We think about STP problem/event...

We successfully enable lacp and stp logs on cisco for now and we are wainting the next random error.

thks for your help and advices

regards

[lozair31]

The error come again on our switchs.....

Reading and analyzing the logs it seems linked to server reboot.

The attached doc show our network topology.

The server reboot all the nights à 2:30 AM.

Every 3 weeks, this reboot is followed by a channel-misconfig error on Port-channel 14 of the Cisco 6500.

But the logs below seems indicate it's the hp5700 which cut the port for unknown reason and when the port come up in the followiong seconds there is a channel misconfiguration detection at the Cisco level.

Thanks for your advices

[lozair31]

network topology

[peyrache]

so now need to debug LACP packets during event i think

do you have log from switch where Server is connected ?

JY

[peyrache]

also there a know issue on Blade switch with LACP dont' know is relevant in your case

ymptom:
LACP packets received from downstream port-channel members are flooded by the 3120 switch instead of being processed.

Conditions:
Issue seen on CBS3120 switch running 12.2(40)EX1

Workaround:
Instead of LACP please use a "mode on" for bundling the member links.
