Creating an Emulated LAN

Use the

add lecselanpolicy

command to create ELAN join policies. The following is an example of creating an

ELAN join policy based on the By Packet Size policy.

SmartSwitch # add lecselanpolicy

PolicyIndex() : 2

— Can be any value other than one (1)

Type() : ?

— Use

to see possible types

ELAN Policy Type (Values from 1 to 7 representing, in order, the policies BestEffort, byATMAddress,

byMacAddress, byRouteDescriptor, byLANType, byPacketSize and byELANName).

Type() : 6

— Specify type 6, assign ELAN by packet size requested by client

Priority() : 1000

— Weight the policy at 1000

SmartSwitch #

Note

The lower the numerical value of a priority, the higher the priority. In the example
above, a priority value of 1000 was specified. Subsequently, This policy will be
tried before Best Effort (policy value = 65001).

Use the

show lecselanpolicy

command to show the newly created ELAN join policy.

SmartSwitch # show lecselanpolicy

Index Assignment Policy Priority Value

==============================================================================

1 Best Effort (Proprietary) 65001

2 By Packet Size 1000

— The created policy, its index number, and its priority

SmartSwitch #

Note

In the example above, index 2 (or greater) was used because the

Best Effort

policy reserves index one.

The LECSELANLEC Table

Many of the ELAN join policies use the information supplied by the

add lecselanlec

command. Use the

add

lecselanlec

command to create a list of clients and to assign the ELAN each client should join.

Note

You can also assign a TLV set to be used by the client on the specified ELAN.

Clients are identified within the

lecselanlecs

list by one (or a combination of) the following attributes:

•

ATM address

•

MAC address

•

Token Ring route descriptor (segment ID and bridge number)

•

IP address
