Command Reference
fr map clns
Purpose Use the fr map clns command to add an FR mapping for OSI packets.
Use the undo fr map clns command to remove an FR mapping established for
OSI packets.
Syntax fr map clns dlci [ nonstandard | ietf ] [ compression frf9 ]
undo fr map clns dlci
Parameters dlci
Local virtual circuit number. Valid values are 16 to
1007.
nonstandard
Specifies to encapsulate the mapping in a
non-standard format.
ietf
Specifies to encapsulate the mapping in IETF format.
frf9
Specifies to adopt payload compression. (This option is
not available for point-to-point interfaces.)
Default No FR mapping is established for OSI packets by default.
Example With a virtual circuit (DLCI = 40) existing on Serial1/0/0 interface, configure a static
address mapping.
[3Com -Serial1/0/0] fr map clns 40

Description Address mapping can be achieved through manually configuring or reverse address
resolution protocol (RARP). Static address mapping can be achieved through manually
configuring, which is applicable when there are few peer ESs or the default routes
exist. Whereas dynamic address mapping can be achieved through RARP, which is
applicable when the peer router supports RARP and the network is relatively complex.
As OSI packets cannot be forwarded through Layer 3 address mapping, you can only
map by protocol for OSI packets. There can only be one mapping for OSI packets. So
you must remove the existing map before you create a new one.
