ONTROL OMMANDS TO ONTROL
you use the rules of a basic or advanced ACL, only the source IP address and its
mask, the destination IP address and its mask, and the time-range parameter
in them are valid. Similarly, when you use Layer 2 ACLs to implement the ACL
control to the users accessing through Telnet or SSH, incoming/outgoing
requests are restricted based on the source MAC addresses. Therefore, when
you use the rules of a Layer 2 ACL, only the source MAC address and its mask
and the time-range parameter are valid.
When you use a Layer 2 ACL to implement ACL control to the users accessing
■
through Telnet or SSH, only incoming requests are restricted.
If a user fails to log in due to ACL restriction, the system logs the failure,
■
including the IP address, login method, user interface index value and the
cause.
By default, the system does not restrict incoming/outgoing requests.
Example
# Perform ACL control to the users who access the local switch through Telnet
(assuming that ACL 2000 is previously created).
