Virtual terminal line ACLs

To limit Telnet and SSH connections to the switch, apply access lists on a virtual terminal line (VTY).

There is no implicit deny rule. If none of the configured conditions match, the default behavior is to permit. If you need to deny traffic that does not match any of the configured conditions, explicitly configure a deny statement.

  1. Create IPv4 or IPv6 access lists with permit or deny filters; for example:
    OS10(config)# ip access-list permit10
    OS10(config-ipv4-acl)# permit ip 172.16.0.0 255.255.0.0 any
    OS10(config-ipv4-acl)# exit
    OS10(config)#
  2. Enter VTY mode using the line vty command in CONFIGURATION mode.
    OS10(config)# line vty
    OS10(config-line-vty)# 
  3. Apply the access lists to the VTY line with the {ip | ipv6} access-class access-list-name command in LINE-VTY mode.
    OS10(config-line-vty)# ip access-class permit10
View VTY ACL configuration
OS10(config-line-vty)# show configuration
!
line vty
 ip access-class permit10
 ipv6 access-class deny10
OS10(config-line-vty)#
