Configuring Network Channels
The last four selections in the Parameters box are
used to choose which type of server, LECS or LES,
the client is to contact at bootup, and to enter the
ATM network address of the server.
The term "prefix" in the parameter name refers to the
ATM prefix portion of an ATM Network address. The
prefix is thirteen bytes (26 characters) in length and
comes from the ATM switch. The term "ESI/SEL"
refers to the remaining seven bytes of the ATM
network address. It contains the 6-byte MAC address
of the server, followed by a 1-byte SEL (selector)
value.
Configure the four entries for each channel client as
follows:
If you want the client to contact the LECS with the
ATM Forum's "well-known" address, do the following:
a Set all four entries to zero, if they are not set to
zero already.
This is the default setting of the parameters, as
shown in Figure 4-13.
b Go to step 7.
If you want the client to contact the LECS with an
ATM network address other than the ATM Forum's
"well-known" address, do the following:
a Select LECS Network Prefix and enter the first 13
bytes (26 characters) of the LECS's ATM network
address.
b Select LECS ESI/SEL and enter the remaining
seven bytes (14 characters) of the ATM network
address.
c Set the LES Network Prefix and the LES ESI/SEL
parameters to zero, if they are not set to zero
already.
