Looking this scenario, I try to communicate 3Com 3812 and 3Com 7700 swithes. But result is unsuccessfull. 3Com 770 switch: vlan 1 # vlan 2 description LAN-172-16-3-0 protocol-vlan 0 ip 172.16.3.11 255.255.255.0 # vlan 3 description LAN-1 broadcast-suppression 50 # vlan 4 description GUESTS broadcast-suppression 50 # interface Vlan-interface2 ip address 172.16.3.11 255.255.255.0 # interface GigabitEthernet2/0/1 port link-type trunk port trunk permit vlan 2 to 4 I can't to communicate with 7700 through 3812 (pc - 3812 - 7700). Hi Scott!
Looking this scenario, I try to communicate 3Com 3812 and 3Com 7700 swithes. But result is unsuccessfull.
3Com 770 switch:
vlan 1
#
vlan 2
description LAN-172-16-3-0
protocol-vlan 0 ip 172.16.3.11 255.255.255.0
#
vlan 3
description LAN-1
broadcast-suppression 50
#
vlan 4
description GUESTS
broadcast-suppression 50
#
interface Vlan-interface2
ip address 172.16.3.11 255.255.255.0
#
interface GigabitEthernet2/0/1
port link-type trunk
port trunk permit vlan 2 to 4

I can’t to communicate with 7700 through 3812 (pc – 3812 – 7700).

Yes, a layer3 device would be required. The example did not include the assumed gateway allowing the clients and servers to communicate. Thanks for the comment!

Or its necessary to add a router or L3 switch? Thanks in advance for your help.

Before I was trying to access the switch while connected to a port in different VLAN, maybe it's why I couldn't.

Congratulations for your experience!. Now I'm looking for a solution to an issue that happened once I made the trunking configuration, I can't access the 3com switch telnetting the ip address of the switch any more, I don't have idea why. And by now I don't have the cable needed to connect to the console of the switch. Any suggestion Thank you Hi,your post was really useful. Congratulations for your experience!.
