Creating an Emulated LAN

IP Over ATM and LANE

6.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’.
