7 Interface access and system information
Interface access: console/serial link, web, and inbound telnet
The interface access features in the switch operate properly by default. However, you can modify
or disable access features to suit your particular needs. Similarly, you can choose to leave the
system information parameters at their default settings. However, modifying these parameters can
help you to more easily distinguish one device from another in your network.
Interface access features:

In most cases, the default configuration is acceptable for standard operation.
NOTE: Basic switch security is through passwords. You can gain additional security by using
the security features described in the Access Security Guide for your switch. You can also simply
block unauthorized access via the WebAgent or Telnet (as described in this section) and installing
the switch in a locked environment.

Terminal line width and length settings
For console/serial link and inbound telnet sessions, the switch output:
• Uses whatever width is set by the terminal program. If width is not specified, 80 characters
is the default.
• Automatically wraps on word boundaries (such as spaces) for non-columnar output
• Automatically wraps on column boundaries for columnar output
HP recommends that you do not set your terminal width (terminal width <y>) above 150
columns. (Windows telnet displays up to 156 characters on 1280 pixel wide display, so 150 is
comfortably within this).
