Setting Tcp Parameters - Huawei S9300 Configuration Manual

S9300&S9300E Terabit Routing Switch
Configuration Guide - IP Service
The relationship between the icmp host-unreachable send (system view) and the icmp host-unreachable
send (interface view) commands are as follows:
l When the S9300&S9300E is disabled from sending ICMP Host Unreachable packets, all the interfaces of
l When the S9300&S9300E is enabled to send ICMP Host Unreachable packets, all the interfaces of the
Step 8 Run:
interface vlanif vlan-id
The VLANIF interface view is displayed.
Step 9 Run:
icmp redirect send
The interface is enabled to send ICMP redirection packets.
Step 10 Run:
icmp host-unreachable send
The interface is enabled to send ICMP host unreachable packets.

6.3.5 Setting TCP Parameters

Context
You can set the following TCP parameters:
l
l
l
If you run the tcp window command repeatedly in the same system view, the latest configuration
overrides the previous configuration.
Do as follows on the S9300&S9300E.
Procedure
Step 1 Run:
system-view
Issue 01 (2012-03-15)
NOTE
the S9300&S9300E do not send the ICMP Host Unreachable packets even if you run the undo icmp host-
unreachable send (interface view) command in the interface view.
S9300&S9300E can send ICMP Host Unreachable packets, which conforms to the default setting. In this
case, you can run the undo icmp host-unreachable send (interface view) command to disable a specified
interface from sending the ICMP Host Unreachable packets.
SYN-Wait timer: When sending packets with the SYN flag, TCP starts the SYN-Wait timer.
If no response is received before the SYN-Wait timer expires, the TCP connection ends.
The timeout interval of the TCP SYN-Wait timer is an integer that ranges from 2 to 600,
in seconds. By default, the value is 75s.
FIN-Wait timer: When the TCP connection status changes from FIN_WAIT_1 to
FIN_WAIT_2, the FIN-Wait timer is enabled. If no packet with the FIN flag is received
before the FIN-Wait timer expires, the TCP connection ends. The timeout interval of the
TCP FIN-Wait timer is an integer that ranges from 76 to 3600, in seconds. By default, the
value is 675s.
Size of the packet receive or transmit buffer: The value is an integer that ranges from 1 to
32, in Kbytes. By default, the value is 8 Kbytes.
