Switch configuration (OS 10.x)
3.1.9

Enable Jumbo frames and flow control (optional)

Note: This step is optional as iSCSI auto-detection and auto-configuration enabled in previous step will
enable Jumbo frames with MTU 9216 and enable receive flowcontrol on all ports once PS Series or SC
Series storage ports are detected on the switch.
OS10(config)# interface range ethernet 1/1/1–1/1/48
OS10(conf-range-eth1/1/1-1/1/48)# mtu 9216
OS10(conf-range-eth1/1/1-1/1/48)# flowcontrol receive on
OS10(conf-range-eth1/1/1-1/1/48)# flowcontrol transmit off
3.1.10

Configure spanning tree on edge ports

OS10(conf-range-eth1/1/1-1/1/48)# spanning-tree port type edge
OS10(conf-range-eth1/1/1-1/1/48)# exit
Note: Spanning tree is enabled by default. If it needs to be reconfigured, use the following command.
OS10(config)# no spanning-tree disable
OS10(config)# exit
3.1.11

Configure port channel for link aggregation

Use the following commands to create a port channel or link aggregation used as an interconnect between
two switches.
OS10# configure terminal
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
3.1.12

Configure port channel member ports

This configuration guide uses ports 1/1/49 and 1/1/50 as port-channel member ports which are configured
using following commands.
OS10(config)# interface range ethernet 1/1/49,1/1/50
OS10(conf-range-eth1/1/49,1/1/50)# no switchport
OS10(conf-range-eth1/1/49,1/1/50)# channel-group 1 mode active
OS10(conf-range-eth1/1/49,1/1/50)# mtu 9216
OS10(conf-range-eth1/1/49,1/1/50)# flowcontrol receive on
OS10(conf-range-eth1/1/49,1/1/50)# flowcontrol transmit off
OS10(conf-range-eth1/1/49,1/1/50)# exit
OS10(config)# exit
