Migrating brand information

Migration guidelines

To make sure that an IRF fabric and all its switches can correctly work after a brand migration, follow

these guidelines:

• If the H3C or 3Com switch has a fiber transceiver modules not licensed by HP, replace it with an HP

licensed fiber transceiver module before the migration. Any non-HP licensed fiber transceiver

module cannot work after a brand migration.

• After a 3Com switch migrates to an HP switch:

○ The baud rate of its console port automatically changes from 19200 bps to 9600 bps. You must

make sure that the console terminal uses the same baud rate as the console port.

○ The order of its physical ports changes to be the same as on the HP switch chassis, and the port

numbers marked on the 3Com chassis panel become useless. You must create a port number

map between the 3Com switch and the HP switch and re-configure the ports. For the order of

the physical ports on the HP switch chassis, see its installation guide.

○ All the default settings change to be the same as on the HP switch. If the 3Com switch has a

different default setting for a feature than the HP switch, you must reconfigure the feature or

make sure that the difference does not impact your network.

Migration prerequisites

Perform the following tasks before you perform brand migration on an H3C or 3Com switch:

• Get the Boot ROM image and system software image for the HP switch that can form an IRF fabric

with the H3C or 3Com switch (see Table 1).

• Use the HP Boot ROM image to upgrade the Boot ROM of the H3C or 3Com switch.

• Download the HP system software image to Flash memory and set it as the main file.

NOTE:

• If a switch uses a Boot ROM image file (in .btm) separate from the system software image file (in .bin),

HP recommends that you use the bootrom update command to up

rade the Boot ROM. If no separate

Boot ROM image file is released, the switch can automatically upgrades the Boot ROM when you

upgrade the system software image.

• For the 3Com Switch 4510G, you must use the Boot ROM image for the HP A5120 EI switches to

rade its Boot ROM and use the system software ima

e for the HP A5500 SI switches as the main file.

Configuration procedure

CAUTION:

You cannot restore the original brand information after a brand migration.

Follow these steps to enable brand migration for H3C or 3Com switches:
