Performing Diagnostics 13 - 11

If uploading to another Ethernet or Token Ring Bridge, the ﬁlename

option must have a value even though the value is not used by the

remote Ethernet or Token Ring Bridge.

5. Select the put option. The unit will begin an FTP session to the

remote host PC or Ethernet or Token Ring Bridge.

Uploading the Unit’s conﬁguration (Conﬁg)

You may use this option to save the conﬁguration on a remote host or

PC in a format suitable for later downloading using FTP or BOOTP.

You are ﬁrst prompted for the name of the ﬁle to be created on the

remote system. Once the ﬁlename is entered the transfer will begin.

Downloading Using the Internet Boot Protocol (Bootp/DHCP)

The Bootp/DHCP option is enabled by default when the Ethernet or

Token Ring Bridge is powered on. The process for downloading ﬁrm-

ware ﬁles using the Bootp/DHCP parameter is:

1. On power up, the Ethernet or Token Ring Bridge will issue boot pro-

tocol requests to see if there are any Bootp or DHCP servers on the

infrastructure that have been conﬁgured with the unit infrastructure

address.

2. If no response is found, the request is repeated up to 30 times with a

4 second wait after the ﬁrst request. It then doubles the time

between requests for each additional retry. If there is still no

response, the unit gives up.

3. If multiple responses are received, the unit will pick a DHCP server

over a Bootp server.

4. If a response is received, the IP address assigned to this unit by the

server is compared to the conﬁgured value. If they are different, the

conﬁgured value is changed.

5. The downloaded ﬁle is examined. If the ﬁle is not empty, it is

assumed to be a conﬁguration ﬁle in the format produced by the

“conﬁguration dump” menu command. A Trivial File Transfer

Protocol (TFTP) dialogue is used to retrieve the ﬁle from the server.
