Configuring LACP on an S3148P

Question

I'm replacing an HP 2920-48G with LAG configured with a S3148p and I'm trying to LAG/LACP ports 1 and 2 of the S3148p to connect to a Dell S4048T-ON. On an HP switch, which I'm familiar working with, creating a LAG is just a couple of mouse clicks. On the Dell S3148p, which I'm not familiar with, it's interesting. The Internet searches I've performed have been no help. I get some variation of these errors: % Error: Gi 1/1 Port is part of a LAG.% Error: Gi 1/2 Port is part of a LAG.% Error: Port is not in Layer-2 mode Gi 1/1.% Error: Port is not in Layer-2 mode Gi 1/2.CMD-(CLI):[Error: Port is not in default mode Gi 1/1]by default from consoleCMD-(CLI):[Error: Gi 1/1 Port is part of a non-default VLAN.]by default from consoleCMD-(CLI):[Error: Port is not in default mode Gi 1/1]by default from consoleCMD-(CLI):[Error: Port is not in Layer-2 mode Gi 1/2.]by default from console Here is one of the many variations of commands I've tried: { s3148p#confs3148p(conf)#interface range gigabitethernet 1/1-1/2s3148p(conf-if-range-gi-1/1-1/2)#portmode hybrids3148p(conf-if-range-gi-1/1-1/2)#switchports3148p(conf-if-range-gi-1/1-1/2)#port-channel-protocol lacp% Error: Port is not in default mode Gi 1/1% Error: Port is not in default mode Gi 1/2s3148p(conf-if-range-gi-1/1-1/2)#exits3148p(conf)#interface gigabitethernet 1/1s3148p(conf-if-gi-1/1)#port-channel-protocol lacp% Error: Port is not in default mode Gi 1/1 } Is there a s31xx specific guide other than the command guide which was no help that explains how to configure LAG/LACP on s31xxs switches? Thank you!

Hello NotMe9,   It could be from it being cabled wrong or configured differently on the other end. Has it ever worked? What is the configuration on the S4048T for the port channel ?

Thank you for the manual. I've read and typed and the LAG always says "LACP LAG 12 is an individual link" and "Port State: Not in Bundle":

{

s3148p#show lacp 12
Port-channel 12 admin up, oper down, mode lacp
LACP Fast Switch-Over Disabled
Actor System ID: Priority 32768, Address f0d4.e298.7971
Partner System ID: Priority 0, Address 0000.0000.0000
Actor Admin Key 12, Oper Key 12, Partner Oper Key 0, VLT Peer Oper Key 12
LACP LAG 12 is an individual link

LACP LAG 12 is a normal LAG

A - Active LACP, B - Passive LACP, C - Short Timeout, D - Long Timeout
E - Aggregatable Link, F - Individual Link, G - IN_SYNC, H - OUT_OF_SYNC
I - Collection enabled, J - Collection disabled, K - Distribution enabled
L - Distribution disabled, M - Partner Defaulted, N - Partner Non-defaulted,
O - Receiver is in expired state, P - Receiver is not in expired state

Port Gi 1/1 is enabled, LACP is enabled and mode is lacp
Port State: Not in Bundle
Actor Admin: State ADEHJLMP Key 12 Priority 32768
Oper: State ADEHJLMP Key 12 Priority 32768
Partner is not present

Port Gi 1/2 is enabled, LACP is enabled and mode is lacp
Port State: Not in Bundle
--More-- Actor Admin: State ADEHJLMP Key 12 Priority 32768
Oper: State ADEHJLMP Key 12 Priority 32768
Partner is not present

}

It looks like it should work:

{

s3148p(conf)#interface gigabitethernet 1/1
s3148p(conf-if-gi-1/1)#show config
!
interface GigabitEthernet 1/1
no ip address
!
port-channel-protocol LACP
port-channel 12 mode active
no shutdown
s3148p(conf-if-gi-1/1)#exit
s3148p(conf)#interface gigabitethernet 1/2
s3148p(conf-if-gi-1/2)#show config
!
interface GigabitEthernet 1/2
no ip address
!
port-channel-protocol LACP
port-channel 12 mode active
no shutdown
s3148p(conf-if-gi-1/2)#

}

Is there a command missing?

Thank you!

Apologies for the late reply. A lot of people in my ear. It was decided to connect the two switches differently.
