Configure the uplink ports on the Top-of-Rack (ToR) switches

1. Establish a terminal connection to the first ToR switch (Switch1).
2. Enter global configuration mode.

   configure terminal

3. Configure the port channel for the uplinks.

   interface port-channel 50
   description Uplink
   no shutdown
   switchport mode trunk
   switchport access vlan 1
   vlt-port-channel 50
   mtu 9216
   exit

4. Configure the uplink ports on the switch.
   NOTE:For iSCSI or NVMe/TCP best practices, it is recommended to disable flow control as demonstrated below.

   interface ethernet 1/1/29
   description Uplink_Ports
   no shutdown
   channel-group 50 mode active
   no switchport
   flowcontrol receive off
   flowcontrol transmit off
   mtu 9216
   exit 
   
   interface ethernet 1/1/30
   description Uplink_Ports
   no shutdown
   channel-group 50 mode active
   no switchport
   flowcontrol receive off
   flowcontrol transmit off
   mtu 9216
   exit

5. Commit the configuration to the NVRAM.

   copy running-configuration startup-configuration

6. Repeat steps 1 - 5 on the second ToR switch (Switch2).
