LESLNNIInfo
LESLNNIInfo
Use LESLNNIInfo to show information on VCCs established for an instance of LES/BUS servers. The VCCs are
established for LNNI purposes. Each instance of LES/BUS servers establishes two point-to-multipoint and one or
more point-to-point VCCs. One point-to-multipoint VCC is from the LES to its LES neighbors. The second
point-to-multipoint VCC is from the BUS to its BUS neighbors. One point-to-point VCC is from the LES to its LECS
(the LECS to which the LES is directly attached). Another point-to-point VCC might be established from the LES to
each LES neighbor for the purpose of synchronizing database information (Cache Synchcronization VCC).
Information on LES and BUS neighbors is passed to the LES from its LECS. The information is stored in a database
accessible to both the LES and BUS. Each instance of LES/BUS servers may serve several ELANs.
Note
An LES is considered directly attached to an LECS if it has established a VCC to
that LECS (to get configuration information from that LECS). The LES is not
necessarily on the same switch as the LECS to which it is directly attached. Each
LES is colocated with a BUS. Though the LES and BUS are separate entities, the
two together are considered an instance of LES/BUS servers. The BUS is not
attached to an LECS, but it exchanges information with the LECS indirectly
through the LES colocated with the BUS.

[ELANNumber] ELAN for which information is
requested. 0-125 or All All
Output Parameter Description
[LES Config Direct VCC] The VPI/VCI of the point-to-point connection from the LES to its LECS.
[LES Control Co-ordinate VCC] The VPI/VCI of the outgoing point-to-multipoint connection from the LES.

BUS.
The following information is provided for each neighbor.
[Neighbor Address] ATM address of an LES neighbor (and the BUS colocated with it.).
