LANE Redundancy
Start-up Delay
LANE Redundancy
Limitations
The LANE redundancy mechanism does not begin operating at system
power-on but rather has a user-adjustable start-up delay. There are two
reasons for this delay:


To allow time for the routing table in the switch to become established


To allow time for the LES to initialize
Only after the start-up delay does the LECS begin establishing ATM
connections to the LESs in the network. During the delay period, all
requesting LECs are assigned to the primary LES of the requested ELAN.
You can adjust the delay period through the LMA and defaults to 600
seconds. (See "Update Startup Delay" on page 239.)
The following restrictions obtain:


Number of LECs that are allowed to connect to the
CoreBuilder 9000 ATM Enterprise Switch: 1000


Number of redundant ELANs: 128
If you assign a redundant LES to more than 64 ELANs, you cannot change
to the LECS-based LANE redundancy mode.


Number of LES per ELAN: 2


Start-up delay: 1-15 minutes, defaults to 10 minutes (user adjustable)
