! Disable flow control on Ethernet 0/5

QTECH(config-if-ethernet-0/5)#no flow-control

Use following command in any configuration mode to display interface flow-control:

show flow-control [ interface-num ]

For example:

! Display flow-control of Ethernet 0/0/5

QTECH(config-if-ethernet-0/0/5)#show flow-control ethernet 0/0/5

2.2.11 Configure interface combo type

Use this command to configure interface combo type. E0/0/1 to e0/0/4 are combo interfaces

which can be configured. Combo type can be divided into TX and FX and it is defaulted to be

TX. Configure it in inteface configuration mode:

 Configure interface combo type

combo { fiber | copper }

Example:

! Configure e0/0/1 to be TX

QTECH(config-if-ethernet-0/0/1)#combo copper

2.2.12 Port mode configuration

Use this command to configure port mode. If a port configures to be a trunk port, the vlan

mode changes untagged into tagged, and if a port configures to be an access one, the vlan

mode changes tagged into untagged. Configure it in interface configuration mode:

 Configure port mode

switchport mode { trunk | access }

 Restore default port mode: access port

no switchport mode

For example:

! Configure Ethernet 0/0/1 to be trunk port

QTECH(config-if-ethernet-0/0/1)#switchport mode trunk

2.2.13 Trunk allowed VLAN configuration

Use switchport trunk allowed vlan command to add trunk port to specified VLAN. Use no

switchport trunk allowed vlan command to remove trunk port from specified vlan.

 Add trunk port to specified vlan

switchport trunk allowed vlan { vlan-list | all }

 Remove trunk port from specified vlan

no switchport trunk allowed vlan { vlan-list | all }

For example:

! Add trunk ports Ethernet0/0/1 to VLAN 3, 4, 70 to 150

QTECH(config-if-ethernet-0/0/1)# switchport trunk allowed vlan 3,4, 70- 150

2.2.14 The default vlan-id of trunk port configuration

Use switchport trunk native vlan command to configure the default vlan-id (pvid) of trunk port.

When receiving untagged packet, it will be transferred to VLAN defaulted VLAN ID. Packet

receiving and sending follow IEEE 802.1Q. Configure it in interface configuration:

 Configure default VLAN ID of trunk port
