Access Control
57.1 Access Control Overview
This chapter describes how to control access to the Switch.
FTP is allowed one session each, Telnet and SSH share nine sessions, up to five web sessions (five different
user names and passwords) and/or limitless SNMP access control sessions are allowed.
Telnet access control session cannot coexist when multi-login is disabled.
57.1.1 What You Can Do
• Use the Service Access Control screen (Section 57.2 on page 355) to decide what services you may
use to access the Switch.
• Use the Remote Management screen (Section 57.3 on page 356) to specify a group of one or more
“trusted computers” from which an administrator may use a service to manage the Switch.
• Use the Account Security screen (Section 57.4 on page 357) to encrypt all passwords configured in
the Switch. You can also display the authentication, authorization, external authentication server
information (RADIUS or TACACS+), system and SNMP user account information in the configuration file
saved.
57.2 Service Access Control
Service Access Control allows you to decide what services you may use to access the Switch. You may
also change the default service port and configure “trusted computers” for each service in the
SECURITY > Access Control > Remote Management screen (discussed later). Click SECURITY > Access
Control > Service Access Control to display the following screen.
