Use the ACL to control user login
by source IP address
acl [ ipv6 ] acl-number { inbound |

Required
inbound: Filters incoming Telnet
packets.
outbound: Filters outgoing Telnet
packets.
Configuring source and destination IP-based login control over
Telnet users
Because advanced ACLs can match both source and destination IP addresses of packets, you can use
advanced ACLs to implement source and destination IP-based login control over Telnet users. Advanced
ACLs are numbered from 3000 to 3999. For more information about ACL, see the ACL and QoS
Configuration Guide.
Follow these steps to configure source and destination IP-based login control over Telnet users:

Configuring source MAC-based login control over Telnet users
Ethernet frame header ACLs can match the source MAC addresses of packets, so you can use Ethernet
frame header ACLs to implement source MAC-based login control over Telnet users. Ethernet frame
header ACLs are numbered from 4000 to 4999. For more information about ACL, see the ACL and QoS
Configuration Guide.
