Configuring LAN Emulation
LANE Configuration Tasks
To set up the LECS for the default emulated LAN, perform the following steps, beginning in global
configuration mode:
In Step 2, enter the ATM address of the server for the specified emulated LAN, as noted in your
worksheet and obtained in
Displaying LANE Default Addresses, page 14-6
. You can have any number
of servers per emulated LAN for fault tolerance. Entry order determines priority: the first entry has the
highest priority unless you override it with the index option.
If you are setting up only a default emulated LAN, the
elan-name
value in Step 2 is the same as the
default emulated LAN name you provide in Step 4.
To set up fault-tolerant operation, see
Configuring Fault-Tolerant Operation, page 14-15
.
For examples of these commands, see
LANE Configuration Examples, page 14-17
.
Setting Up the Database for Unrestricted-Membership Emulated LANs
When you set up a database for unrestricted emulated LANs, you create database entries that link the
name of each emulated LAN to the ATM address of its
server
.
However, you can choose
not
to specify the locations of the LANE clients. That is, when you set up the
configuration server database, you do not have to provide any database entries that link the ATM
addresses or media access control (MAC) addresses of any
clients
with the emulated LAN name.
To configure a router or switch router as the LECS for multiple emulated LANs with unrestricted
membership, perform the following steps, beginning in global configuration mode:
Command
Purpose
Step 1
Switch(config)#
lane database
database-name
Switch(lane-config-database)#
Creates a named database for the LECS.
Step 2
Switch(lane-config-database)#
name
elan
-
name
server-atm-address
atm-address
[
index
n
]
In the configuration database, binds the name of
the emulated LAN to the ATM address of the
LES.
Step 3
Switch(lane-config-database)#
name
elan-name
local-seg-id
seg-num
(Token Ring only.) In the configuration database,
specifies the ring number for the emulated LAN.
(Catalyst 8510 MSR and LightStream 1010)
Step 4
Switch(lane-config-database)#
default-name
elan
-
name
In the configuration database, assigns an
emulated LAN to the LECS trying to join without
specifying an ELAN name.
Command
Purpose
Step 1
Switch(config)#
lane database
database-name
Switch(lane-config-database)#
Creates a named database for the LECS.
Step 2
Switch(lane-config-database)#
name
elan-name1
server-atm-address
atm-address
[
index
n
]
In the configuration database, binds the name of
the first emulated LAN to the ATM address of the
LES for that emulated LAN.
Step 3
Switch(lane-config-database)#
name
elan-name1
local-seg-id
seg-num
(Token Ring only.) In the configuration database,
specifies the ring number for the first emulated
LAN. (Catalyst 8510 MSR and
LightStream 1010)
