R0106-HP MSR Router Series Interface Command Reference(V7)

28
• When congested, the interface sends a flow control frame to its peer.
• Upon receiving a flow control frame from the peer, the interface suspends sending packets.
Examples
# Enable TxRx mode generic flow control on the interface GigabitEthernet 2/0/1.
<Sysname> system-view
[Sysname] interface gigabitethernet 2/0/1
[Sysname-GigabitEthernet2/0/1] flow-control
flow-control receive enable
IMPORTANT:
This command is not applicable to interfaces on an SIC-1GEC interface card.
Use flow-control receive enable to enable Rx mode generic flow control on an Ethernet port.
Use undo flow-control to disable generic flow control on an Ethernet interface.
Syntax
flow-control receive enable
undo flow-control
Default
Rx flow control is disabled on Ethernet interfaces.
Views
Ethernet interface view
Predefined user roles
network-admin
Usage guidelines
With the flow-control receive enable command configured, an interface can receive, but not send, flow
control frames. When the interface receives a flow control frame from its peer, it suspends sending
packets to the peer. When traffic congestion occurs on the interface, it cannot send flow control frames
to the peer.
To handle unidirectional traffic congestion on a link, configure the flow-control receive enable command
at one end, and the flow-control command at the other. To enable both ends of the link to handle traffic
congestion, configure the flow-control command at both ends.
Examples
# Enable Rx mode generic flow control on GigabitEthernet 2/0/1.
<Sysname> system-view
[Sysname] interface gigabitethernet 2/0/1
[Sysname-gigabitethernet 2/0/1] flow-control receive enable
