Parameter Description

Default
Settings
The reset packet is sent when the port-unreachable
packet is received.
Command
mode Global configuration mode.
Usage
guidelines
When the TCP module distributes TCP packets, if the
TCP session to which such packets belong cannot be
found, a reset packet will be replied to the peer end to
terminate the TCP session. The attacker may initiate
attacks by sending excess port-unreachable TCP
packets. You can use this command to prohibit sending
the reset packet when the port-unreachable packet is
received.
