I have seen some folks on this list a couple of weeks ago that were
discussion switches and specifically the 3Com switches. So I know we
have some switch experts out there. I need some help as I can't get
any from the documentation or maybe my brain is just too fried to
understand it. Sometimes I can't see the forest for the trees which
can make you feel dumb as a rock!
We have the 3Com Switch 1000 - 24 port. It is setup with several (5)
VLAN's. All NIC's on all 5 VLAN's are using an ip from the same class
C address and yet I don't seem to be able to communicated between the
VLAN's. Now I realize that the idea is to gain better control and
security over your network and the separated VLAN's are only supposed
to be able to talk to each other through the router. All 5 backbone
ports are setup correctly (including security off) and are connected
to a repeater (only a short distance away) which is connected to the
network gateway router (Cisco 2501). Do I need to be "routing" these
VLAN's on an individual basis? What I mean is, do I need to add 5 new
routes to the cisco? The IP on the switch ether is also one from the
same class C. Does this ether need to be included in the cisco
router? The cisco is already routing the whole class C anyway.
Subnetting seems to be redundant and a waste of IP's since I already
have a switch. I have been over this many times in the last couple of
days and can't seem to get a handle on it. I would appreciate any
help and/or suggestions. Thanx.................
