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.
Note: To avoid exceeding the default QoS buffer pool size, do not configure DCB parameters on all switch
ports. Configure only the switch ports that will be operating with DCB traffic. The following example configures
DCB on ports 1 to 30, and on ports 53 and 54.
3.1 Disable iSCSI
OS10# configure terminal
OS10(config)# no iscsi enable
OS10(config)# no iscsi session-monitoring enable
OS10(config)# exit
3.2 Disable 802.3x flowcontrol on selected ports
OS10# configure terminal
OS10(config)# interface range ethernet 1/1/1–1/1/30
OS10(conf-range-eth1/1/1-1/1/30)# no flowcontrol receive
OS10(conf-range-eth1/1/1-1/1/30)# no flowcontrol transmit
OS10(conf-range-eth1/1/1-1/1/30)# exit
3.3 Create tagged VLAN for selected 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 versions 10.3.2 to 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
OS10(config)#
