Manual configuration of the redundant switch parameters listed in the
table above must be done on a CoreBuilder 7000 other than the active
one. Only upon configuration completion can the redundant switch be
utilized in the active CoreBuilder 7000.
Information Based on
the MAC Address
When the redundant switching module takes over, it is assigned the IP
address of the active switching module. However, each switching module
board has a unique MAC address burned into its EPROM. This MAC
address is used by the CoreBuilder 7000 for three purposes:
For the IP stack
For the LES ATM address user part
For calculating a unique number to be assigned to the ELAN name
The ELAN names have the format ELANxxxx_y where xxxx is a unique
number calculated using the MAC address and y is an integer from 0 to
15 automatically assigned to each of the 16 default LESs of the
CoreBuilder 7000. In this way, each LES has a unique ELAN name and
unique ATM address.
When a redundant switching module takes over from the active
switching module, the IP address, the ELAN names, and LES address
remain the same as they were in the active module.
