You can control access to the switch by creating an access policy. An access policy specifies the hosts or networks that can access the switch through various services, such as Telnet, SNMP, HTTP, and rlogin.
You can define network stations that are explicitly allowed to access the switch or network stations that are explicitly forbidden to access the switch. For each service you can also specify the level of access, such as read-only or read/write/all.
The services supported on the OM8000 include FTP, TFTP, RLOGIN and TELNET. These services use daemons and, to enhance security, these daemons are started unconditionally. When a flag is disabled, all existing connections are abruptly terminated, and the daemon remains idle (does not accept connection requests). Additionally, if HA-CPU is on and you disable a daemon, all the existing connections, even to the standby CPU, are abruptly terminated.
This section describes how to use Access Policy to perform the following tasks:
