I have 3 com switch and cisco switch and 2 NDs and core switch
The connection is like this:
core connect to the 2 NDs
first ND1 connect to cisco switch
second ND2 connect to 3com switch
every switch connect to 2 pcs
ND1 (vlan1 by default and vlan 172)
nd2 (vlan1 by default and vlan 172)
pc1 connect to vlan 1 (cisco sw)
pc2 connect to vlan 172 (3com sw)
But when I connect the pc1 to vlan 172 (cisco switch) the network with other switch fail (cant see it and it cant connect to any thing)
Is there is any problem with connecting cisco with 3com ???
