Configuring Network Channels 4-11

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:

aSet 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.

bGo 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:

aSelect LECS Network Prefixand enter the first 13 bytes (26 characters) of the LECS’s ATM network address.

bSelect LECS ESI/SEL and enter the remaining seven bytes (14 characters) of the ATM network address.

cSet the LES Network Prefix and the LES ESI/SEL parameters to zero, if they are not set to zero already.
