Assigning an Emulated LAN Type
The emulated LAN type specifies the data frame format that the LEC uses when it
joins an emulated LAN. ATM allows you to choose from three emulated LAN
types: unspecified (the default), IEEE 802.3, or IEEE 802.5.
When you assign unspecified as the LAN type, the client obtains the ELAN type
from the LECS when it joins an emulated LAN. When you assign IEEE 802.3 or
IEEE 802.5, the client joins only Ethernet or token ring ELANs (respectively).
Using the BCC
To change the emulated LAN type, navigate to the service record prompt (for
example,
box; atm/11/1; lec-service/newyork
) and enter:
lan-type
<value>
value
is the type of ELAN that you want this LEC to join: unspecified, ieee8023,
or ieee8025.
For example, the following command allows the LEC to join only Ethernet
(IEEE 802.3) emulated LANs:
lec-service/newyork#
lan-type ieee8023
lec-service/newyork#
Note:
If you set the LE client to run in manual configuration mode (see
“Selecting a LEC Configuration Mode
” on page 8-8), you must specify an
ELAN type of IEEE 802.3 or IEEE 802.5.
