Cisco Nexus 9372PX - Configure the Port-Channel; Enable Jumbo Frames on Edge Ports; Enable Link Level Flow Control (802.3 X) on Edge Ports

9 Cisco Nexus 9372PX Switch Configuration Guide for Dell PS Series SANs | SCG3665
2.7 Configure the Port-Channel
switch(config)#interface port-channel 1
switch(config-if)#switchport mode trunk
switch(config-if)#spanning-tree port type network
switch(config-if)#vpc peer-link
switch(config-if)#mtu 9216
switch(config-if)#flowcontrol receive on
switch(config-if)#flowcontrol send on
switch(config-if)#exit
switch(config)#interface ethernet 1/49-50
switch(config-if)#switchport mode trunk
switch(config-if)#channel-group 1
switch(config-if)#mtu 9216
switch(config-if)#no shutdown
switch(config-if)#exit
2.8 Enable Jumbo Frames on edge ports
switch(config)#system jumbomtu 9216
switch(config)#interface ethernet 1/1-48
switch(config-if-range)#mtu 9216
2.9 Enable link level flow control (802.3x) on edge ports
Perform this step for each individual port that is connected to a storage controller or a host server interface
port, or specify a range of ports to configure.
switch(config-if-range)#priority-flow-control mode off
switch(config-if-range)#flowcontrol send off
switch(config-if-range)#flowcontrol receive on
switch(config-if-range)#exit
Note: Optionally, to reduce egress port packet drops, use the following command to enable the ultra-burst
feature mode:
switch(config)# hardware qos ns-buffer-profile ultra-burst
