Switch Description
-fb Burn ram.cmp in flash (only for cmp files)
-em #
Use this switch to set Ethernet mode.
0 = 10 Base-T half-duplex
1 = 10 Base-T full-duplex
2 = 100 Base-TX half-duplex
3 = 100 Base-TX full-duplex
4 = auto-negotiate (default)
For detailed information on Ethernet interface configuration, see
Configuration.
-br This parameter is used
This switch takes effect only from the next gateway reset.
Set the number of BootP requests the gateway
sends during start-up. The gateway stops
sending BootP requests when either BootP
reply is received or number of retries is
reached.
1 = 1 BootP retry, 1 second
2 = 2 BootP retries, 3 seconds
3 = 3 BootP retries, 6 seconds
4 = 10 BootP retries, 30 seconds
5 = 20 BootP retries, 60 seconds
6 = 40 BootP retries, 120 seconds
7 = 100 BootP retries, 300 seconds
15 = BootP retries indefinitely
-bs Use –bs 1 to enable the Selective BootP mechanism.
Use –bs 0 to disable the Selective BootP mechanism.
The Selective BootP mechanism (available from Boot version 1.92) enables the gateways
integral BootP client to filter unsolicited BootP/DHCP replies (accepts only BootP replies that
contain the text AUDC in the vendor specific information field). This option is useful in
environments where enterprise BootP/DHCP servers provide undesired responses to the
gateways BootP requests.
-be Use -be 1 for the device to send device-related initial startup information (such as board type,
current IP address, software version) in the vendor specific information field (in the BootP
request). This information can be viewed in the main screen of the BootP/TFTP, under column
'Client Info (see
the extreme right). For a full list of the vendor specific Information fields, see
Information Field.
This option is not available on DHCP servers.

Set the number of DHCP packets the gateway
sends.
After all packets were sent, if there's still no

1 = 4 DHCP packets
2 = 5 DHCP packets
3 = 6 DHCP packets (default)
4 = 7 DHCP packets
5 = 8 DHCP packets
6 = 9 DHCP packets
7 = 10 DHCP packets
