Hi,
Thanks for responding to my question. However, another person wrote that I
should just do a "show version" and use that "base" mac address. Is that
ever true? Sometimes true? or never true?
Also, according to the 3550 config guide, the 3550 switch will automatically
generate a DHCP request upon bootup if a config file isn't present.
Although it didn't say anything about this, my assumption is that if there
isn't any config file, then there's only the default vlan, and all
interfaces are in their default state (whatever that is). Is that true?
And, if so, what mac address do I use? Is it possible that there's more
than 1 mac address that will work for this purpose?
Also, suppose you're deploying a new Cat 3550 to a network that is using
DHCP but you don't want the 3550 to use DHCP. What do you do then? Do you
1st have to config the 3550 before connecting it do the network?
The config guide isn't very clear about the sequence. I'm not sure whether
the switch will go into the set up program first or request data from a DHCP
server.
BTW, please forgive me for all these questions - I don't have a 3550 to test
these different things.
Thanks for your help. Jim
