DCB disable ile bende sorun çözüldü. Eğer  aktif-aktif çalışan iki backbone varsa ikisinde de kapatınız.

2.3 Disable DCB

Note: For DCB environments, skip this section. For non-DCB environments, DCB must be manually

disabled using the following steps:

console>enable

console#configure

console(config)#no dcb enable

console(config)#exit

2.4 Configure out of band (OOB) management port

console>enable

console>#configure

console(config)#interface out-of-band

console(config-if)#ip address ipaddress mask gateway

console(config-if)#exit

2.5 Configure login credentials

console(config)#username admin password yourpassword privilege 15

console(config)#enable password yourpassword

console(config)#exit

2.6 Enable iSCSI optimization feature

This feature, enabled by default, is activated when EqualLogic arrays are detected. It automatically

performs the following:

• Configures jumbo frames to 9216 on all ports.

8 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 Configure spanning tree portfast on edge ports

Note: If iSCSI optimization is enabled, spanning tree portfast is automatically configured on ports

connected to EqualLogic arrays. These manual steps must be performed on switch ports connected to

hosts servers.

console#configure

console(config)#interface range tengigabitethernet all

console(config-if)#spanning-tree portfast

console(config-if)#exit

2.9 Configure port channel for LAG

These commands configure the switch interconnect as a LAG.

console(conf)#interface Port-channel 1

console(conf-if-po1)#mtu 9216

console(conf-if-po1)#exit

2.10 Configure QSFP ports for LAG

These commands assign 40Gb QSFP ports to the Port Channel.

console(conf)#interface range fortygigabitethernet 1/1/1-2

console(conf-if)#no spanning-tree portfast

console(conf-if)#mtu 9216

console(conf-if)#channel-group 1 mode active

console(conf-if)#exit

console(conf)#exit

2.11 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

2.12 Configure additional switch

Repeat the commands from section 2 to configure the second switch.

10 SCG1001 PowerConnect 8100 Series Configuration Guide

3 Configure Data Center Bridging (DCB) (Optional)

DCB is enabled by default. This section shows the steps required to configure DCB.

Note: You must complete the Dell recommended switch configuration steps in sections 2.1 to 2.12

before configuring the switch for DCB mode.

3.1 Enable DCB

If DCB was previously disabled, it must be manually re-enabled.

console#configure

console(config)#dcb enable

3.2 Create VLAN

console#configure

console(conf)# vlan vlan-id

Note: You must supply a VLAN id. The valid range is 2-4093.

console(conf)#exit
