Dell EMC recommended switch configuration
12 Dell EMC Networking S4248-ON Switch Configuration Guide for Dell EMC Unity, SC Series, and PS Series
iSCSI SANs | SCG4077
2.9 Enable Jumbo frames and flow control
OS10(config)# interface range ethernet 1/1/1–1/1/40
OS10(conf-range-eth1/1/1-1/1/40)# mtu 9216
OS10(conf-range-eth1/1/1-1/1/40)# flowcontrol receive on
OS10(conf-range-eth1/1/1-1/1/40)# flowcontrol transmit off
2.10 Configure spanning tree on edge ports
OS10(conf-range-eth1/1/1-1/1/40)# spanning-tree port type edge
OS10(conf-range-eth1/1/1-1/1/40)# exit
OS10(config)# no spanning-tree disable
2.11 Configure port channel for link aggregation
Note: Configuring for a port channel is mandatory for PS Series, optional for SC Series, and not applicable to
Dell EMC Unity SANs.
These commands create a port channel or link aggregation used as an interconnect between two switches.
OS10(config)# interface port-channel 1
OS10(conf-if-po-1)#mtu 9216
OS10(conf-if-po-1)#no shutdown
OS10(conf-if-po-1)#exit
2.12 Configure port channel member ports
This configuration guide uses ports 1/1/47 and 1/1/48 as port channel member ports, and they are configured
using the following commands.
OS10(config)# interface range ethernet 1/1/47,1/1/48
OS10(conf-range-eth1/1/47,1/1/48)# no switchport
OS10(conf-range-eth1/1/47,1/1/48)# channel-group 1 mode active
OS10(conf-range-eth1/1/47,1/1/48)# mtu 9216
OS10(conf-range-eth1/1/47,1/1/48)# flowcontrol receive on
OS10(conf-range-eth1/1/47,1/1/48)# flowcontrol transmit off
OS10(conf-range-eth1/1/47,1/1/48)# exit
OS10(config)# exit
2.13 Save configuration
OS10#copy running-configuration startup-configuration
OS10#reload
System configuration has been modified. Save? [yes/no]: yes
Proceed to reboot the system? [confirm yes/no]:yes
