Hi !
I'm not famillar we CatOS, so I would like to understand the following :
"set trunk 3/1 off negotiate 2-200"
my understanding of "off" argument and "negotiate" argument are contractditionnary to each other the first disable trunking and the second one negotiate it ! We also specifiiyng vlan ID which are allowed or not on this interface !
I know this configuration command is permit, because I see it on production switch !
someone could explain to me ?
Thanks !

I understand what you mean. It says in the command reference:
To configure trunk ports and to add VLANs to the allowed VLAN list for existing trunks, use the set trunk command.
set trunk mod/port {on | off | desirable | auto | nonegotiate} [vlans]
[isl | dot1q | dot10 | lane | negotiate]
negotiate | (Optional) Specifies that the port become an ISL (preferred) or 802.1Q trunk, depending on the configuration and capabilities of the neighboring port. |
But here is an example that might help clarify:

Apparently you are turning of trunking / DTP but allowing the formation of an etherchannel. In this exmaple its connected to a workstation/server. Is that also true in your network?

Hi !
no ! the switch is connected to a Cisco router in my configuration.... Base on my understanding the etherchannel is mostly setup by
Cat6000 (enable)set port channel 5/1-2 mode onPort(s) 5/1-2 channel mode set to on.
Cat6000 (enable)
than thoses one
set trunk 5/1 off negotiate 1-1005,1025-4094
!--- Trunking is disabled.
set trunk 5/2 off negotiate 1-1005,1025-4094
!--- Trunking is disabled.
But, we see same command I see in my switch !
Thanks !
