Applying A Waas Policy To An Interface; Configuring Tfo Parameters - HPE FlexNetwork MSR Series Comware 7 Layer 3 - Ip Services Configuration Manuals

Applying a WAAS policy to an interface

Apply a WAAS policy to an interface that connects to the WAN. The device optimizes or passes
through the traffic entering and leaving the WAN according to the configured policy. If the incoming
and outgoing interfaces of the traffic are both connected to the WAN, the traffic is not optimized.
A global logical interface (such as a Layer 3 aggregate interface or VLAN interface) that spans
multiple cards or IRF member devices can be used to connect to the WAN. To ensure the traffic
optimization effect for such an interface, use the service command to specify one of these cards or
IRF member devices to forward traffic for the interface.
A WAAS policy can be applied to multiple interfaces. Only one WAAS policy can be applied to an
interface.
To apply a WAAS policy to an interface:
Step
1. Enter system view.
2. Enter interface view.
3. Apply a WAAS policy to
the interface.

Configuring TFO parameters

The congestion window size changes with the congestion status and transmission speed. An
appropriate initial congestion window size can quickly restore the network to its full transmission
capacity after congestion occurs.
After you enable TFO keepalives, the system starts the 2-hour TCP keepalive timer. If the local
device does not send or receive any data when the timer expires, it sends a keepalive to the peer to
maintain the connection.
The receiving buffer size specifies the size of data that can be received. It affects network
throughput.
To configure TFO parameters:
Step
1. Enter system view.
2. Set the initial congestion
window size.
3. Enable TFO keepalives.
4. Set the receiving buffer
size.
