Parameters
acl-number: Specifies an ACL number in the range of 2000 to 4999.
Usage guidelines
You can use this command to filter the IPv4 SSH clients' request packets by referencing an ACL:
• If the ACL has rules configured, only the IPv4 SSH clients whose request packets match the permit
statement in this ACL can access the server.
• If the ACL does not exist, or if the ACL does not have any statement, all the IPv4 SSH clients can
access the server.
The ACL filters only new SSH connections after the configuration.
If you execute this command multiple times, the most recent configuration takes effect.
Examples
# Configure ACL 2001 and reference the ACL to allow only an IPv4 SSH client at 1.1.1.1 to access the
server.
<Sysname> system-view

[Sysname-acl-basic-2001] rule permit source 1.1.1.1 0
