2.2.11 Enable/disable interface flow-control
If the port is crowded, it needs controlling to avoid congestion and data loss. Use flow-control
command to control the flow. Use following command to enable/disable flow-control on current
Ethernet port.
flow-control
no flow-control
For example:
! Enable flow control on Ethernet 0/5
QTECH(config-if-ethernet-0/5)#flow-control
! 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 0/5
QTECH(config-if-ethernet-0/5)#show flow-control ethernet 0/5
2.2.12 Port mode configuration
This command is for configuring port type. Port can be trunk, hybrid and access, trunk port is
tagged in the vlan it belongs to, so the packets sent by this port is tagged; hybrid port can be
tagged and untagged in the vlan it belongs to, so it allows packets of multiple VLANs to be
sent with or without the Tag label;accessonly port belongs to one VLAN and it is untagged in
VLAN. Configure it in interface configuration mode:
Configure port mode
switchport mode { trunk | hybrid | access }
Restore to default mode, hybrid port
no switchport mode
For example:
! Configure port 1 to be trunk
QTECH(config-if-ethernet-0/1)#switchport mode trunk
Shift to other port mode:
1) to access: keep default VLAN to be untagged vlan and deleted from other VLANs;
2) to hybrid: All vlan tagged status to be untagged;
3) to trunk: All vlan tagged status to be tagged;
2.2.13 The default vlan-id of port configuration
Use this command to configure the default vlan-id. Use the no command to restore it to default
vlan ID. When received untagged packets, this port will forward it to default vlan. Packets
sending and receiving is with IEEE 802.1Q standard. Configure it in interface configuration
mode:
Configure default VLAN ID
switchport default vlan vlan-id
Restore default VLAN ID
no switchport default vlan
