Operations Manual

If the secondary LECS ATM address is not found, a search is made for the

“Well Known ” LECS Address.

This sequence will continue until a connection is made. Since all conﬁguration

information originates from the LECS, your switch will not know what

ELAN’s are available until the LECS acknowledges that connection.

Default ELAN. You can also create a default ELAN on the LECS server

with the “Super LEC.” If, for instance, you want to assign all of the devices

attached to an LEC to a default ELAN, then use the “Super LEC” ATM

address.

All subsequent MAC requests sent by the LEC can then be assigned to the

default ELAN by the LECS. This process allows you to conﬁgure all of the

ports of your switch for one ELAN by only conﬁguring a single ATM address.

Note that not all LEC servers will not function in exactly the same way. What

is important to know is simply that conﬁguration requests are sent to the

LECS for every new device.

ELAN Requests. Once a connection to the LECS is completed, data can be

forwarded. At this time your switch will send 64 conﬁguration requests to the

LECS in an attempt to identify the 64 ELANs that are available. All

conﬁgured addresses will be acknowledged and the associated ELANs will be

joined. Established ELANs will also be identiﬁed in the ELAN Name column

on the Emulated LAN definitions submenu.

Select Emulated LAN definitions from the LAN Emulation menu.

This screen displays ELAN Number, Name and Status. Note that only 16

ELANs can be shown on a screen. To view additional ELANs simply scroll

forward by entering

“N” for Next Page or enter a speciﬁc ELAN number.
