3 Configure Data Center Bridging (optional)
To enable Data Center Bridging (DCB) mode on the switch, use the commands in this section.
Note: Complete the switch configuration steps in section 2 before configuring the switch for DCB mode.
3.1 Disable iSCSI
OS10# configure terminal
OS10(config)# no iscsi enable
OS10(config)# no iscsi session-monitoring enable
3.2 Disable 802.3x flowcontrol on all ports
OS10(config)# interface range ethernet 1/1/1–1/1/40
OS10(conf-range-eth1/1/1-1/1/40)# no flowcontrol receive
OS10(conf-range-eth1/1/1-1/1/40)# no flowcontrol transmit
OS10(conf-range-eth1/1/1-1/1/40)# exit
3.3 Create tagged VLAN for all ports and port-channels
Note: You must supply a VLAN ID. The valid range is 2 to 4093.
The following commands will configure single VLAN ID. If desired, multiple VLAN IDs can be created on the
switch and assigned to ports.
OS10(config)# interface vlan <vlan-id>
OS10(conf-if-vl-<vlan-id>)# mtu 9216
OS10(conf-if-vl-<vlan-id>)# no shutdown
OS10(conf-if-vl-<vlan-id>)# exit
3.4 Create QoS policy map with dot1p values as trusted
Note: This section only applies to switches running OS version 10.4.0. Skip this section if your switch is
running OS version 10.4.1 or later.
OS10(config)# policy-map type qos <trust-policy-map-name>
OS10(config-pmap-qos)# class class-trust
OS10(config-pmap-c-qos)# trust dot1p
OS10(config-pmap-c-qos)# exit
OS10(config-pmap-qos)# exit
