Enhanced secure
Hsecure
SSH secure
Enable SSH secure mode to allow only SSH to be used and disable all other protocols which include Telnet, rlogin, FTP, SNMP, TFTP, HTTP, and HTTPS. Enabling this mode disables Telnet, rlogin, FTP, SNMP, TFTP, HTTP, and HTTPS by setting the boot flags for these protocols to off. You can over-ride the configuration and enable required protocols individually for run-time use. The administrator must enable required protocols individually for run-time use again following a reboot even if you save the configuration. This is because the SSH secure mode enable takes precedence at the time of reboot and the other protocols will be disabled even though the configuration file has them set to enabled.
Note
Rlogin is only supported on VSP 8600 Series.
Note
Disabling SSH secure mode will not automatically enable the OA&M protocols that were disabled. The boot flags for the required protocols will have to be individually set to enabled.
The following table lists the differences between enhanced secure mode and hsecure mode.
