During Secureplatform installation, I used "bcm5700" NIC.  Recently, I want
to replace this NIC to "Intel pro 100".  So, anybody know how to change NIC
model since Secureplatform was installed?

Hi evrenbuyer, a bit unclear what you mean by changing  model - CP has been supporting Intel
Pro 1000g cards starting NGX R60 HFA_X , not to say Intel pro 100. Why would you need to change
NIC model ? Depending on your NGX (I guess it is R61) driver for the NIC is supposed to be already
there, so should be enough to plug the NIC and let Linux/Splat recognize it and find relevant driver.
After that running through sysconfig to make sure IP /mask /etc are ok would be enough.
BTW  Do you have in  /etc/modules.conf  lines like these ?
alias eth1 bcm5700
alias eth2 bcm5700
......................

No need to change it anyway , all is done automatically.
NOTE before any change I'd back up all /etc/  folder at least.

H0 Yurisk thx for your reply,

I'm not very good at Secureplatform and I wonder if my whole configuration may fail after NIC replacement. I have a HW problem on one of my NICs. Which is shown as "pcnet32" below, and I want to replace it with Intel Pro 100 Server adapter. Do u think is it gonna be a big problem for my configuration to do so? And as you explained but I want to make sure that is it gonna be automaticallay recognized as eth2?

alias eth0 bcm5700
alias eth2 pcnet32
alias eth1 3c59x

Thx for your time and interest....

Well, in theory anything is possible, but ... I've personally seen few dozen NIC replacement
being done all Splat (mostly with the client being on the phone ) and haven't yet seen new NIC install/replacement that ended in system becoming totally damaged. Problems I am aware of with NIC
replacements are -  new NIC wasnt recognized at start up correctly (had to manually set duplex/speed/autonegoiation settings ), NIC wasnt recognized at all - so when running sysconfig to test/set configs of this new NIC it was absent, also ifconfig -a didnt show this NIC (turned out
NIC was somehow defective, another one was ok) , there are problems with Quadro (Intel) cards
and their driver (not always). But again that is just my experience - take it as it is.
If you decide to go on with that do at least back up of the current FW configs using upgrade_export
utility in Splat.

2) yes it should be autorecognized as eth2
