Problem configuring Port-Channel between Dell N3024 and S4048
Hello there Dell comunity,
I am getting a hard time to get a connection between the two devices. We are using a QSFP+ Breakout DAC QSFP-4X10G (for now just using 2 ten gigs on the 3024)
Core switch Dell S4048 has this config on the port channel:
interface Port-channel 2
no ip address
portmode hybrid
switchport
channel-member fortyGigE 2/49
no shutdown
interface fortyGigE 2/49
no ip address
no shutdown
Dell N3024 has this config:
interface port-channel 2
port-channel local-preference
description "UPLINK_to_Core_2/50"
spanning-tree disable
switchport mode trunk
switchport general allowed vlan remove 1
switchport trunk native vlan 616
switchport trunk allowed vlan 4-5,10,64-66,251,616
exit
interface Te1/0/1
channel-group 2 mode on
exit
!
interface Te1/0/2
channel-group 2 mode on
exit
The current status of the port-channels are:
On S4048:
cont-core-0#show int port-channel 2
Port-channel 2 is up, line protocol is down(minimum links not up)
Hardware address is 68:4f:64:23:06:27, Current address is 68:4f:64:23:06:27
Interface index is 1258292224
Minimum number of links to bring Port-channel up is 1
Internet address is not set
Mode of IPv4 Address Assignment : NONE
DHCP Client-ID :684f64230627
MTU 1554 bytes, IP MTU 1500 bytes
LineSpeed auto

Output 00.00 Mbits/sec, 0 packets/sec, 0.00% of line-rate
Time since last interface status change: 3d19h40m
On DELL N3024 (the curious things is that it is showing as active)
2nd_FloorCont#show interfaces port-channel 2
Channel Ports Ch-Type Hash Type Min-links Local Prf Rx Util Tx Util
------- ----------------------------- -------- --------- --------- --------- --------- ---------
Po2 Active: Te1/0/1, Te1/0/2 Static 7 1 Enabled 0 0
Both swicthes are configured to allow vlans 4,5,64,65,66,251,616.
By the way, the QSFP port is not even blinking.
Am i missing any other configuration?
Thanks in advance and look forard to hearing from you!

Hello Friends,
The solution was to split QSFP 40gb in 4 10gb subint. I-ve used this link as reference:
https://www.dell.com/support/manuals/en-us/dell-emc-os-9/s4048t-on-9.14.2.4-config/splitting-40g-ports-without-reload?guid=guid-1f7f943e-4de3-49ca-bb03-92d5b487cb1c&lang=en-us&dgc=SM&cid=304571&lid=spr7019003238&refid=sm_LITHIUM_spr7019003238&linkId=166564709
With this configuration, you are able to se ethe port-channel up up and then the troubleshooting is made easier.
Thanks and i hope this saves a lot of time for you.
Regards.
Juan.
