ip ftp username name
To view the FTP configuration, use the show running-config ftp command in EXEC privilege mode, as
shown in the example for
Enabling the FTP Server.
Terminal Lines
You can access the system remotely and restrict access to the system by creating user profiles.
Terminal lines on the system provide different means of accessing the system. The virtual terminal lines (VTYs)
connect you through Telnet to the system.
Denying and Permitting Access to a Terminal
Line
Dell Networking recommends applying only standard access control lists (ACLs) to deny and permit access to
VTY lines.
• Layer 3 ACLs deny all traffic that is not explicitly permitted, but in the case of VTY lines, an ACL with no
rules does not deny traffic.
• You cannot use the show ip accounting access-list command to display the contents of an ACL
that is applied only to a VTY line.
• When you use the access-class access-list-name command without specifying the ipv4 or
ipv6 attribute, both IPv4 as well as IPv6 rules that are defined in that ACL are applied to the terminal.
This is a generic way of configuring access restrictions.
• To be able to filter access exclusively using either IPv4 or IPv6 rules, you must use either the ipv4 or
ipv6 attribute along with the access-class access-list-name command. Depending on the
attribute that you specify (ipv4 or ipv6), the ACL processes either IPv4 or IPv6 rules, but not both.
Using this configuration, you can set up two different types of access classes with each class processing
either IPv4 or IPv6 rules separately.
To apply an IP ACL to a line, Use the following command.
• Apply an ACL to a VTY line.
LINE mode
ip access-class access-list [ipv4 | ipv6]
NOTE: If you already have configured generic IP ACL on a terminal line, then you cannot further apply
IPv4 or IPv6 specific filtering on top of this configuration. Similarly, if you have configured either IPv4 or
IPv6 specific filtering on a terminal line, you cannot apply generic IP ACL on top of this configuration.
Before applying any of these configurations, you must first undo the existing configuration using the no
access-class access-list-name [ipv4 | ipv6] command.
Example of an ACL that Permits Terminal Access
To view the configuration, use the show config command in LINE mode.
