Re: LACP randomly fail between hpe5700 and cisco 6509

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..

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.

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.

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

Re: LACP randomly fail between hpe5700 and cisco 6509

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
