I have a ESXi 6.5 (free version) and Cisco 2960.
On Cisco:
interface Port-channel1
switchport mode access
!
interface GigabitEthernet1/1
switchport mode access
channel-group 1 mode on
!
(four interfaces in Port-channel, this is example for 1st interface)(no vlan's! in esxi in settings no vlan's 'None(0)')
On ESXi: I did all config from official guide (and tryed many more solutions (google helps)), I add, all NIC, they active, i choose IP HASH on vSwitch and etc.
doesn't work! so easy configuration, come on! when i connect cabels in switch,on configured ports, i lose connection with hypervisor (and with VM of course). i spend all day trying to understand and setup link aggregation. what could be the problem? maybe 'trunk' mode helps (not sure)? maybe need vlan's?? Not tryed, because I not manage cisco switch, I make a call in headquarters and their admins configure switch(yes, i know, not cool).
Thanks a lot for the any help! God bless your server!
