Logging in to the switch commands

acl (user interface view)

Syntax
To use a basic or advanced ACL:
acl [ ipv6 ] acl-number { inbound | outbound }
undo acl [ ipv6 ] acl-number { inbound | outbound }
To use an Ethernet frame header ACL:
acl acl-number inbound
undo acl acl-number inbound
View
VTY user interface view
Default level
2: System level
Parameters
ipv6: When this keyword is present, the command supports IPv6; otherwise, it supports IPv4.
acl-number: Number of the access control list (ACL):
• Basic ACL: 2000 to 2999
Advanced ACL: 3000 to 3999
•
Ethernet frame header ACL: 4000 to 4999
•
inbound: Restricts Telnet or SSH connections established in the inbound direction through the VTY user
interface. If the received packets for establishing a Telnet or SSH connection are permitted by an ACL rule,
the connection is allowed to be established. When the device functions as a Telnet server or SSH server,
this keyword is used to control access of Telnet clients or SSH clients.
outbound: Restricts Telnet connections established in the outbound direction through the VTY user
interface. If the packets sent for establishing a Telnet connection are permitted by an ACL rule, the
connection is allowed to be established. When the device functions as a Telnet client, this keyword is
used to define Telnet servers accessible to the client.
Description
Use the acl command to reference ACLs to control access to the VTY user interface.
Use the undo acl command to cancel the ACL application. For more information about ACL, see ACL and
QoS Configuration Guide.
By default, access to the VTY user interface is not restricted.
If no ACL is referenced in VTY user interface view, the VTY user interface has no access control over
•
establishing a Telnet or SSH connection.
If an ACL is referenced in VTY user interface view, the connection is permitted to be established
•
only when packets for establishing a Telnet or SSH connection match a permit statement in the ACL.
