Publishing the New MAC Address
A redundant switch that has become active sends a reverse ARP (RARP) to
publish its MAC address to the network devices.
For devices that do not learn MAC addresses from a RARP, you will need
to reset the IP address entry of the CoreBuilder 7000 in their device table.
LES and LECS in One
CoreBuilder 7000
After rebooting, the network resumes normal operation if the LES and
the LECS used are in the same CoreBuilder 7000. When the redundant
switch is inserted in the CoreBuilder 7000, the 16 default LES addresses
are mirrored to the redundant switch’s LECS database.
LES and LECS in
Different CoreBuilder
7000s
After rebooting, the network is unable to resume normal operation if the
LES and the LECS used are not in the same CoreBuilder 7000. Inserting
remote LES addresses into the LECS database is performed manually and
is therefore not mirrored to the redundant switch’s LECS database.
Alias Names
In order to ensure continuous operation of the network, alias names must
be manually updated in the LECS database.
Resetting to Factory
Defaults
The ELAN names and LES addresses (user part) change only if the user
performs a reset to factory defaults by LMA (or Telnet).
After the reset to factory defaults, the MAC address that is burned in the
active switch EPROM supersedes the one that is stored in the flash
memory, which results in new ELAN names and LES addresses.
CAUTION:
Resetting to factory default causes all connections to be
dropped until the new ELAN names are updated in the LECs.
Upgrading the
Software
When you upgrade a new software version to the active switching
module, you must upgrade the redundant switch manually via the
(1) \(4) \(3) \(3) \(1) option in the LMA. While the software is being
upgraded, no redundancy is available on the modules.
