I have 2 stacks of two N4032F (interstack 4x10GE) connected with 4x10GE, mesheh, on to one switch.
Stacks are connected by LACP mode active. This is Core
Some Cisco switches are connected to stack of N4032 with LACP mode active. I issued some communication problems. From Dell stach 1 I can not ping some hosts connected by Dell stack 2.
Some other host are accessable by ping without any problem
Situation changes, after some minutes of ping, communication is lost. Clearing arp on Dell 1 helps for while. There are also some strange communication issues from host to host if communication cross Dell core.
First I switched off additional interfaces in LACP to Cisco leaving only on interface in LACP.. Without any help.
Then I did the same on interstack LACP. When I left only one interface everyting worked perfectly. When I switched on second interface to second member od stack this issue is observed again.
Did anybody have the same problem? Any suggestions.
