Not that I’ve discovered. Unless it’s an identical card type swap, it’s not possible. Even physically identical port layouts (Gen1 4x10g vs Gen1.1 4x10g) won’t work. The new LP won’t come up until you physically remove the card and “no” out the relevant module line in the config. When you do that, it blasts out any interface config that was associated with the card.

This may be changed in newer NetIron versions. I haven’t tried it since 5.2.

Regards,
Mike

Actually Josh, I don't believe that config will remain. I just ran into
this issue (partially) at a customer, he had to remove the first blade from
the config (using the 'no mod xx BR-MLX-10Gx24-DM') command, then insert
the new module and let it re-discover. I am just about certain that
process will zero out any config associated with that slot. The
expectation there is that you can swap identical modules, but any change
should revert back to factory default (for the slot). Your best bet would
be to cut and paste with the relevant ports, sorry to be the bearer of bad
news.

Thanks everyone for your input - unfortunately not as simple as it may have seemed.

Will give a go the old-fashioned way.

Regards,

Josh Farrelly.

Hi all

Just wanted to check if anyone knew whether the configuration that's already applied to interfaces stays valid after a line card is swapped with another.

In this example I am wanting to swap a "BR-MLX-10Gx24-DM 24-port 10GbE Module" with a "NI-MLX-10Gx8-M 8-port 10GbE (M) Module" but I want the relevant configuration for each port to stay exactly the same.

I am assuming so, but thought best to check before proceeding. I can assume we'd only run in to issues where moving to a card with less interfaces (e.g. as the startup-config was applied, no matching interface for eth1/9 on an 8-port card would be found).

You also need to make sure you remove the module line from the config
while the LP slot is empty, it won't let you do it if you've already
inserted the new card.

In 5.6 they added the ability to remove the config while the card is in interactive mode.

Hi,

we also had that issue some years ago moving from 2x 10G to 4x 10G card.
Didn't work.

If rebooting is ok, export the config via tftp, replace the "module ..."
line and the config of the interfaces 9-24, import the new config, power
off, change the linecard, power-on.

regards
Rolf
