• Advanced ACL—3000 to 3999. The ipv6 option is required.
Usage guidelines
If the ACL does not exist or has no rules, all users are permitted to Telnet to the device.
When the ACL exists and has rules, only users permitted by the ACL can Telnet to the device.
This command is not effective for existing Telnet connections.
If you execute this command multiple times, the most recent configuration takes effect.
For more information about ACL, see ACL and QoS Configuration Guide.
