(.cfg), ScreenOS firmware versions, public keys, error messages, certificates, and other
items.
For security devices running ScreenOS 5.0 or later, NSM does not use the TFTP server
on the security device to download ScreenOS firmware versions, certificates, and CRLs
to the managed device. To perform these tasks, you must install a TFTP server on the
NSM device server. For details, see the Network and Security Manager Installation Guide.
NOTE: For security devices running ScreenOS 5.1 and later, Network Security
Manager uses SSP to download ScreenOS firmware versions, certificates,
and CRLs to the managed device.
For TFTP servers, you can specify the following options:
Source interface
Number of times that the server can retry a TFTP communication before the security
device ends the attempt
Timeout (in seconds) before the device terminates an inactive TFTP connection
You can also enable FTP servers to dynamically negotiate a data port other than port
20.
For more detailed explanation about configuring TFTP or FTP servers for security devices,
see the ip commands in the NetScreen CLI Reference Guide.

The Host/Domain Name option enables you to configure a host and domain name for
the security device. The host name is a character string that identifies the device. The
host name, combined with a domain name, enables other devices to access the security
device through a DNS server. If you define a fully qualified domain name (FQDN) for the
device, you can use the FQDN as a gateway for a VPN tunnel.
For information about how to configure a hostname or domain name for a security device,
see the hostname and domain commands in the NetScreen CLI Reference Guide.
