On switch SW3, use the

set lnnistatus

command to enable LNNI and SCSP (Server Cache

Synchronization Protocol).

SW3 # set lnnistatus

LNNIStatus(Disabled) : enable

SCSPStatus(Disabled) : enable

SW3 #

Note

SCSP does not have to be enabled for an LES to take part in LNNI. However,
without SCSP enabled, ARP server information is not shared. As a result, client
connects may be slowed by the client’s need to broadcast to find the LES with the
appropriate ARP information.

7.

On SW3, use the

start les

command to activate the switch’s LES and BUS.

SW3 # start les

NOTICE - 'ZLESSRV' ***** LES started *****

SW3 #

Once the LES/BUS is started, it registers with each LECS running LNNI on the network. In turn, the LECS’
communicate the LES/BUS’ existence to all other distributed LES/BUS’ participating in LNNI. Finally, the LES/BUS
on SW3 begins exchanging server cache information (through SCSP) with other LNNI LES/BUS’.
