The system regards the basic/advanced ACL with the inbound keyword, the basic/advanced ACL with
the outbound keyword, and Ethernet frame header ACL as different types of ACLs, which can coexist in
one VTY user interface. The match order is basic/advanced ACL, Ethernet frame header ACL. At most
one ACL of each type can be referenced in the same VTY user interface, and the last configured one
takes effect.
Examples
# Allow only the user with the IP address of 192.168.1.26 to access the device through Telnet or SSH.
<Sysname> system-view
[Sysname] acl number 2001
[Sysname-acl-basic-2001] rule permit source 192.168.1.26 0
[Sysname-acl-basic-2001] quit
[Sysname] user-interface vty 0
[Sysname-ui-vty0] acl 2001 inbound
After your configuration, user A (with IP address 192.168.1.26) can telnet to the device while user B (with
IP address 192.168.1.60) cannot telnet to the device. Upon a connection failure, a message appears,
saying "%connection closed by remote host!"
# Allow the device to only telnet to the Telnet server with IP address 192.168.1.41.
<Sysname> system-view
[Sysname] acl number 3001
[Sysname-acl-adv-3001] rule permit tcp destination 192.168.1.41 0
[Sysname-acl-adv-3001] quit
[Sysname] user-interface vty 0 4
[Sysname-ui-vty0-4] acl 3001 outbound
[Sysname-ui-vty0-4] return
<Sysname>
After your configuration, if you telnet to 192.168.1.46, your operation fails.
<Sysname> telnet 192.168.1.46
%Can't access the host from this terminal!
But you can telnet to 192.168.1.41.
<Sysname> telnet 192.168.1.41
