Configuring ACL
Control
The Switch 7750 provides several logon and device access measures, including
TELNET access, SNMP access, and HTTP access. The security control, over the
access measures, is provided with the switches to prevent illegal users from
logging onto and accessing the devices. There are two levels of security controls.
At the first level, the user connection is controlled with an ACL filter and only legal
users can be connected to the switch. At the second level, a connected user can
log on to the device only if the user can pass the password authentication.
This chapter introduces how to configure the first level security control to filter the
logon users with ACL. For the information about how to configure the first level
security, see
“System Access”.
Configuring ACL Control is described in the following sections:
■ Configuring ACL Control for TELNET Users
