How to create new port channel on auto-lag enabled switch when ports are already in portmode hybrid?
All,
I am totally new to dell switches (cisco background) and have been asked to create a port channel split over a pair of existing dell aggregator enclosure switches. All the other ports which are connected to the servers except the ports in question I am trying to configure are in port channel.
I have read that they cannot be in a port mode to do auto-lag port channel but I seem to be totally failing to workout how to:
1) Create a new port channel
2) Take the existing ports out of the port mode
3) Add the port to the new port channel.
When I try to create a new port channel interface I get as shown below
agg1(conf)#int po16
Error: Command allowed only for uplink Lag.
The port(s) I am try to change currently have this config:
interface TenGigabitEthernet 0/1
mtu 12000
portmode hybrid
switchport
vlan tagged 220,223,950
flowcontrol rx on tx off
!
protocol lldp
advertise management-tlv management-address system-name
dcbx port-role auto-downstream
no shutdown
And I am trying to get them in to the same config as this example port on the same switch (with a different port channel unique to the t0/1 port on both dell aggregators)
interface TenGigabitEthernet 0/2
mtu 12000
vlan tagged 220,223,950
flowcontrol rx on tx off
!
port-channel-protocol LACP
port-channel 1 mode active
!
protocol lldp
advertise management-tlv management-address system-name
dcbx port-role auto-downstream
no shutdown
which is then tied to :
!
interface Port-channel 1
mtu 12000
portmode hybrid
switchport
vlt-peer-lag port-channel 1
no shutdown
link-bundle-monitor enable
I am sure I must be missing some top level command somewhere that allow me to configure but I seem to be going round in circles and the only guides seem to be coming from a fresh switch setup (and concerned I am going to impact the setup of the other ports.
Any pointers would be greatly appreiciated

If this ports are not in production try to apply following commands:
default int te0/1
int te0/1
port-channel-protocol LACP
port-channel 100 mode active
int po100
mtu 12000
portmode hybrid
switchport
vlt-peer-lag port-channel 100
no shutdown
link-bundle-monitor enable
int te0/1
flowcontrol rx on tx off
protocol lldp
advertise management-tlv management-address system-name
dcbx port-role auto-downstream
I believe you should apply your vlans on the configured port-channel and you can try to enter no auto-lag enable on the port level as well. Can check this clearly since I don't have aggregators at this moment

Thanks - unfortunately the switch does not take the command to default the interface config back. (the only option off default is default vlan:
agg1(conf)#default ?
vlan-id Set default VLAN Id
I tried pulling the vlans tagged on to the interfaces I am trying t change but this did not seem to get me any further

Did you tried to configure
no auto-lag enable
on the port level.
Also you should add interface to port-channel first, than it should allow you to add port-channel configs. What switch says, when you trying to add those commands?
int te0/1
port-channel-protocol LACP
port-channel 100 mode active

Thanks -unfortunately per below output I tried removing the vlans and the auto-lag but it doesnt give me any the option to issue the port channel cmd (I''ve listed the ones available under the interface below):
agg1#sho run int t0/1
!
interface TenGigabitEthernet 0/1
mtu 12000
portmode hybrid
switchport
vlan tagged 220,223,950
flowcontrol rx on tx off
no negotiation auto
!
protocol lldp
advertise management-tlv management-address system-name
dcbx port-role auto-downstream
no shutdown
agg1#conf t
agg1(conf)#
agg1(conf)#int t0/1
agg1(conf-if-te-0/1)#no vlan tagged 220,223,950
agg1(conf-if-te-0/1)#no auto-lag enable
Configure interface on peer VLT to sync auto-lag configuration.
agg1#sho run int t0/1

What mode is the switch in? You may need to change to PMUX mode.
# stack-unit unit iom-mode programmable-mux
Once that is done you should have some further commands available.

Thanks -- to confirm it is in VLT mode with another aggregator in the same chassis. All the other ports going to the servers are in port channels which are working without issue. Just the first port T0/1 on both aggregators are not in a channel

Sorry, I did not catch that, so this switch is setup as a VLT peer with another switch? In that case you will need to leave it in vlt mode. I will keep doing some research.

Thanks for the reply I VLT mode (if I found the right cmd to advise):
agg1#show system stack-unit 0 iom-mode
Unit Boot-Mode Next-Boot
------------------------------------------------
0 vlt vlt
Looking at going in the PMUX mode, it sounds like you have to reboot to change the mode. Is there any other impact (i.e. would any of the existing VLT config be lost)?

Does anyone have any suggestions? As I am a little lost on how to proceed, particularly with the other ports on the aggregators being in production
