Using the CLI 258
Management ACL
In addition to user access control, the system also supports filtering of
management protocol packets addressed to the switch over the in-band ports.
This capability allows individual hosts or subnets to access the switch using
specific management protocols.
The administrator defines a management profile, which identifies
management protocols such as the following:
• Telnet.
• SSH and the keying information to use for SSH.
• HTTP.
• HTTPS and the security certificate to be used.
• SNMPv1/v2c and the read and read/write community strings to be used.
• SNMPv3 and the security information for used this protocol.
For each of these management profiles, the administrator defines the list of
hosts or subnets from which the management profiles may be used. The
management ACL capability only applies to in-band ports and may not be
configured on the out-of-band management port.
Other CLI Tools and Capabilities
The CLI has several other capabilities associated with its primary functions.
Terminal Paging
The default terminal width and length for CLI displays is 79 characters and
25 lines, respectively. The length setting is used to control the number of lines
the CLI will display before it pauses. For example, the CLI pauses at 24 lines
and prompts the user with the --More-- or (q)uit prompt on the 25th line.
The CLI waits for the user to press either <q> or <Enter> or any other key.
If the user presses any key other than <Enter> or <q>, the CLI shows the
next page. A <q> key stops the display and returns to the CLI prompt. The
<Enter> key advances the display by one line. Use the terminal length
command to change the number of lines displayed in a page. A terminal
length of 0 disables pagination. This option is not recommended for serial
console speeds of less than 115200.
