2.2
Power on the two switches.
Connect a serial cable to the serial port of the first switch.
Using Putty or another terminal utility, open a serial connection session to the switch.
Open your terminal emulator and configure it to use the serial port (usually COM1, but this may vary
depending on your system). Configure serial communications for 9600,N,8,1 and no flow control.
Connect the (QSFP) LAG cables between the switches. See this configuration in Figure 1.

SCG1001
PowerConnect 8100 Series Configuration Guide
• Disables unicast storm.
• Enables spanning tree portfast on ports connected to EqualLogic arrays.
• Configures flow control on all ports.
Note: Spanning tree portfast must be manually configured for host facing ports. Refer to section 2.8.
console#configure
console(config)#iscsi enable
Enabling iSCSI Optimization will enable Flow Control which may cause all the
interfaces to temporarily go down.
Are you sure you want to continue? (y/n) y
console(config)#exit
2.7
Enable flow control (optional)
Note: If iSCSI optimization is enabled, flow control is automatically configured on all switch ports upon
detection of an EqualLogic Array. Follow the manual steps below if you choose to disable iSCSI
optimization feature. If you are configuring the switch for DCB mode, skip this section.
console#configure
console(config)#flowcontrol
This operation may take a few minutes.
Management interfaces will not be available during this time.
Are you sure you want to continue? (y/n)y
console(config)#exit
2.8

Reverting from DCB to non-DCB configuration (Optional)
One method to revert from a DCB configured switch to a non-DCB configured switch is to delete the
current configuration (startup-config) and follow the steps in Section 2. If deleting the current
configuration is not an option, then use the following procedure to unconfigure DCB and enable standard
flow control.
Note: This is a disruptive operation that requires down time. The arrays will temporarily lose
communication with each other. Power off all arrays and hosts connected to the SAN before proceeding
with these steps.
4.1
Disable DCB and the DCB policies
console#configure
console(config)#no dcb enable
console(config)# no traffic-class-group weight
console(config)#no classofservice dot1p-mapping
console(config)#no classofservice traffic-class-group
console(config)#no iscsi cos
console(config)#interface range tengigabitethernet all
console(config-if)#datacenter-bridging
console(config-if-dcb)#no priority-flow-control mode
console(config-if-dcb)#no priority-flow-control priority
console(config-if-dcb)#exit
console(config-if)#exit
console(config)#interface range fortygigabitethernet all
console(config-if)#datacenter-bridging
console(config-if-dcb)#no priority-flow-control mode
console(conf-if-dcb)#no priority-flow-control priority
12
SCG1001
PowerConnect 8100 Series Configuration Guide
console(config-if-dcb)#exit
console(config-if)#exit
4.2
Revert to default VLAN ID on switch and arrays
Once DCB is disabled on the switch, the EqualLogic arrays will no longer use the VLAN ID that was
configured when DCB was enabled. The arrays will revert to the default or native VLAN. Therefore, a valid
VLAN must be configured for all host servers, switches, and EqualLogic array members. A valid VLAN can
use the default or native VLAN ID (typically 0 or 1) or a specific VLAN can be configured (for example,
VLAN 100). If a non-default VLAN is configured, then any ports connected to the arrays must be
configured as “untagged”.
Use the steps below to configure the native VLAN on the switch.
console#configure
console(config)#interface range tengigabitethernet all
console(config-if)#no switchport mode
console(conf-if)#exit
console(config)#interface range fortygigabitethernet all
console(config-if)#no switchport mode
console(config-if)#exit
console(config)#interface port-channel 1
console(config-if)#no switchport mode
console(config-if)#exit
console(config)#no vlan vlan-id
console(config)#exit
4.3
Save configuration
console# copy running-config startup-config
This operation may take a few minutes.
Management interfaces will not be available during this time.
Are you sure you want to save? (y/n)y
