1.On both SW1 and SW2, enter the stop lecs command to make sure each LECS is down

SW1 # stop lecs

Confirm(y/n)?:y

NOTICE - 'LECS' ***** LECS shutdown *****

SW1 #

2.On both SW1 and SW2, enter the stop les command to stop each switch’s LES and BUS

SW1 # stop les

STOPPING LES/BUS

Confirm(y/n)?:y

NOTICE - 'ZLESSRV' ***** LES shutdown *****

SW1 #

3.On both SW1 and SW2, enter the set lnniinfo command to assign a number to each switch’s LECS. Make sure that each LECSID is unique.

SW1 # set lnniinfo

 

LECSID(-1)

: 0 — On SW1, LECSID will be zero

SW1 #

Similarly, on SW2, enter the set lnniinfo command, specifying a different LECSID for SW2

SW2# set lnniinfo

 

LECSID(-1)

: 1 — On SW2, LECSID will be one

SW2 #

Note The default LECID -1, indicates that the LECS is not used on this switch. The default value (-1) is used as the LECID on switches participating in LNNI that are running only the LES/BUS (see next section, “Configuring LNNI Distributed LES/BUS servers”).

4.On both SW1 and SW2 enter the set lnnistatus command to enable LNNI and SCSP (Server Cache Synchronization Protocol).

SW1

# set lnnistatus

 

LNNIStatus(Disabled)

: enable

SCSPStatus(Disabled)

: enable

SW1

#

 

Enter the show lnnistatus command to make certain that LNNI has started on each switch

SW1

# show lnnistatus

 

LNNI Status

: Enabled

SCSP Status

: Enabled

SW1

#

 

5.On both SW1 and SW2, use the start les and start lecs commands to start LANE services

SW1 # start les

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

SW1 # start lecs

NOTICE - 'LECS' ***** LECS started *****

SW1 #
