Hello Friends,   The solution was to split QSFP 40gb in 4 10gb subint. I-ve used this link as reference: [URL]   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.    
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) [IMAGE] Core switch Dell S4048 has this config on the port channel: interface Port-channel 2no ip addressportmode hybridswitchportchannel-member fortyGigE 2/49no shutdown   interface fortyGigE 2/49no ip addressno 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 2Port-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:64:23:06:27Interface index is 1258292224Minimum number of links to bring Port-channel up is 1Internet address is not setMode of IPv4 Address Assignment : NONEDHCP Client-ID :684f64230627MTU 1554 bytes, IP MTU 1500 bytesLineSpeed autoMembers in this channel: Fo 2/49(D)ARP type: ARPA, ARP Timeout 04:00:00Queueing strategy: fifoInput Statistics:0 packets, 0 bytes0 64-byte pkts, 0 over 64-byte pkts, 0 over 127-byte pkts0 over 255-byte pkts, 0 over 511-byte pkts, 0 over 1023-byte pkts0 Multicasts, 0 Broadcasts, 0 Unicasts0 runts, 0 giants, 0 throttles0 CRC, 0 overrun, 0 discardedOutput Statistics:0 packets, 0 bytes, 0 underruns0 64-byte pkts, 0 over 64-byte pkts, 0 over 127-byte pkts0 over 255-byte pkts, 0 over 511-byte pkts, 0 over 1023-byte pkts0 Multicasts, 0 Broadcasts, 0 Unicasts0 throttles, 0 discarded, 0 collisions, 0 wreddropsRate info (interval 299 seconds):Input 00.00 Mbits/sec, 0 packets/sec, 0.00% of line-rateOutput 00.00 Mbits/sec, 0 packets/sec, 0.00% of line-rateTime 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!
