I think this is very basic for someone who has some ecperience with Cisco Firewalls.

I have a Cisco PIX515 and I want to set both it's "inside" and "outside" ethernet interfaces to 100 HALF duplex. I have all the passwords. What commands should I use?

On the switches I used to manage I did this:

config t

int fastethernet 0/1

speed 100

duplex half

<CTRL-Z>

write mem

done.

With the 515 PIX I can't get that far. I enter the config mode:

config t

then I see, by using "show int" that both the ethernet0 and ethernet1 interfaces are set to 100 full duplex. What should I do? "speed" and "duplex" commands are not available.

Thank you in advance...
