This is Zeeshan. I Have a pix firewall 525 and its IOS version is 6.3(3). Actually both my interfaces ethernet 0 and ethernet 1 are administratively shutdown and now I want to bring up both these interfaces......I have tried so in the configuration mode by using the command "no interface ethernet1 auto shutdown" according to the help available on the IOS, but after i press "Enter" it shows me the command for help and the command does not executes....so, does any body have some idea about this? that how to "no shutdown" an interface on PIX 525??
