Uh...this is not quite correct.
Out of the box, it is true that the switch will have no VLAN info except
VLAN 1, which is the default VLAN. However, the subnet mask would need to
be correct on both end stations in order for PING to function between them.
The switch really has nothing to do with this process except to allow them
contact with each other. It is the end stations that actually facilitate
the PING.
So, to answer the original question, the end stations will be able to PING
each other (with the switch right out of the box) PROVIDED the subnet masks
are correct and match each other on both ends.
Think of it this way: right out of the box, a 29xx switch acts more or less
like a Layer 1 hub, with no real Layer 2 stuff going on except the
maintenance of an ARP table.
Hope this helps!

These are my thoughts,
If the switch was right out of the box, the stations could ping each other
no matter what subnet mask you were using. The reason being, they are
located in the same broadcast domain, vlan1. This is the default vlan for
all switched ports at this time. The first station would arp for the other,
it would get a response because they are on the same layer 2 broadcast
domain and they could speak directly using the switch.
Switches by default with no mls, are layer two devices. They have no
concept of IP. They make decision based on layer 2 MAC addresses and the
ports they are connected to. If these stations were in different vlans, the
situation would change. You then have created two broadcast domains and in
order for the devices to talk, a router or mls entry would be needed.
Someone please correct me if I am wrong.

Depends on the subnet mask you are using, for instance
142.102.3.1 with a subnet mask of 255.255.0.0
142.102.2.1 also with a subnet of 255.255.0.0
The 2.1 and 3.1 would be on the same subnet, however if you have a
different
subnet mask I don't think it would work.

Hello everyone,
I have a question that probably will sound silly but here it is:
Suppose that you take a new 2924 out of the box and you plug in two
PC's.
You assign address, for example, 142.102.2.1 to the first one and
142.102.3.1 to the second one.There is not any router in this small
network.142.102.2.1 tries to ping 142.102.3.1.The question is: will
142.102.2.1 get a reply and why?
Thanks
alexs
