Flow-Interval - HP 3100 v2 Series Command Reference Manual

Description
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.
Rx mode generic flow control enables an Ethernet interface to receive and process common pause
frames from its peer. The interface does not send common pause frames when it is congested.
By default, Rx flow control is disabled on Ethernet interfaces.
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 Ethernet1/0/1.
<Sysname> system-view
[Sysname] interface ethernet 1/0/1
[Sysname-Ethernet1/0/1] flow-control receive enable

flow-interval

Syntax
flow-interval interval
undo flow-interval
View
Ethernet interface view
Default level
2: System level
Parameters
interval: Sets the statistics polling interval, in seconds. It ranges from 5 to 300 and must be a multiple
of 5.
Description
Use flow-interval to set the interface statistics polling interval.
Use undo flow-interval to restore the default interval.
In system view, use the flow-interval command to set the statistics polling interval for all interfaces.
In Ethernet interface view, use the flow-interval command to set the statistics polling interval for the
interface.
Examples
# Set the statistics polling interval to 100 seconds on Ethernet 1/0/1.
<Sysname> system-view
[Sysname] interface ethernet 1/0/1
[Sysname-Ethernet1/0/1] flow-interval 100
