Hi,
I have 2 C9500-16X with 2 cables connecting each other. I would like to configure the interlinks as port channel LACP. I am getting below error:
%ETC-5-L3DONTBNDL2: Te1/0/14 suspended: LACP currently not enabled on the remote port.
Here are the configs:
Cat9500-SW1:

switchport trunk allowed vlan 10,20,30
switchport mode trunk
switchport nonegotiate

in which SW you receive this message, in that SW only
shut/no shut
the Port channel and it will work normally.

I see it in logs on both switches. When I do show int status, it shows this on both switches:
Te1/0/14 suspended trunk full 10G SFP-10GBase-LR
Te1/0/15 notconnect trunk full 10G SFP-10GBase-LR
Po1 notconnect trunk auto auto N/A
I tried
shut and no shut
on Po1 on both switches but no luck.

%ETC-5-L3DONTBNDL2: Te1/0/14 suspended: LACP currently not enabled on the remote port.
what happends when you
shut and no shut
(is that works ?)
Do you have VLAN created both the end ?
Can you post both the sides:
show etherchannel 1 summary
show interface TenGigabitEthernet1/0/14
show interface TenGigabitEthernet1/0/15

Workaround: configure lACP on the peer or remove LACP config from the affected interface.
Thats super helpful lol

Hello,
Try deleting the port channel and the interface configs. (copy to clipboard)
Configure like this:
configure terminal
interface range TenGigabitEthernet1/0/14-5
channel-group 1 mode active
exit
interface Port-channel1
switchport trunk allowed vlan 10,20,30
switchport mode trunk
switchport nonegotiate
dampening
bandwidth 10000000
load-interval 30
carrier-delay msec 0
***^^ try that exact config on both switches. Also make sure those are the exact interfaces that are plugged in and physically working first and then add the "channel-protocol lacp" if it still doesn't come up.
Hope that helps

I will try the above.
I even wiped all the configs and only put this on both switches:
interface Port-channel1
interface TenGigabitEthernet1/0/14
channel-group 1 mode active
interface TenGigabitEthernet1/0/15
channel-group 1 mode active
It still went in the suspended state.

OK, workaround
config the Port channel as your original post,
then try add port one by one (ONE by ONE), this will give us some hint if there is L1 issue.
try add Te1/0/14
then add Te1/0/15

I tried that as well before and it was still suspending.
L1 should be good as if I enable ports without lacp, it shows connected and I can see cdp nei.
For testing, I changed the mode to pagp and it come up but as standalone.
interface Port-channel1
interface TenGigabitEthernet1/0/14
channel-group 1 mode desirable
interface TenGigabitEthernet1/0/15
channel-group 1 mode desirable
Ports are shows connected. Here is etherc summ output:
Group Port-channel Protocol Ports
------+-------------+-----------+-----------------------------------------------
1 Po1(SD) PAgP Te1/0/14(I) Te1/0/15(I)

Never create the port channel first. Delete the port channel and go into an interface and delete any configs in it (including the channel-group you just made) that is up/up and then create the channel group again under that and let the port channel "create itself". Then under the port channel that's created put your interface configs.

I ran below 2 commands and port went into suspended:
interface range TenGigabitEthernet1/0/14-15
channel-group 1 mode active
It created a port-channel 1 automatically and then went into suspended.

Can you show the output of these commands?
debug etherchannel all
debug lacp all
Also try 2 things:
1. setting one side as passive just to try.
2. Once the port channel is created just configure it as trunk hard coded. Both sides. Form your show int output it looks like it reverted to auto auto. That might be the trunk status and just being weird.

I follow other Post we discuss the command
no port-channel standalone-disable
and it effect on port-channel management traffic (I think LACP is also list under management traffic),
this command prevent the port from deny all traffic included management and hence make both peer don't see LACP message and remain in suspend.
SO TRY PLEASE ADD THIS COMMAND AND SEE RESULT

With your command, the ports are now showing connecting but LACP members are in standalone (I):
Group Port-channel Protocol Ports
------+-------------+-----------+-----------------------------------------------
1 Po1(SD) LACP Te1/0/14(I) Te1/0/15(I)
