IP performance optimization configuration

IP performance optimization overview

Use the following configurations to optimize IP performance:
 Enabling the switch to receive and forward directed broadcasts
 Configuring the TCP send/receive buffer size
 Configuring TCP timers
 Enabling ICMP error packets sending
Enabling reception and forwarding of directed
broadcasts to a directly connected network
Directed broadcast packets are broadcast on a specific network. In the destination IP address of a
directed broadcast, the network ID identifies the target network, and the host ID is made up of all ones. If
the switch is allowed to forward directed broadcasts to a directly connected network, hackers can mount
attacks to the network. However, you can enable the feature when using the following functions:
 UDP Helper: To convert broadcasts to unicasts and forward them to a specified server.
Wake on LAN: To forward directed broadcasts to a host on the remote network.

Enabling reception of directed broadcasts to a directly
connected network
If the switch is enabled to receive directed broadcasts, the switch determines whether to forward them
according to the configuration on the outgoing interface.
Follow these steps to enable the switch to receive directed broadcasts:
To do...
Enter system view
Enable the switch to receive
