3COM 4250T with 3 vlans can't be ping from
Posted on 2004-08-20
I have a 4250T Superstack 3com switch, with 2 VLANS created by me, with the native vlan 1 it makes a total of 3 vlans. I assigned an IP address to the switch. This IP belongs to VLAN 2 (10.10.0.205). When it is created the switch assigns it to vlan 1 and I don't find a way to move it to vlan 2.
This is a scheme of how the switch is connected in my network:
Foundry Switch port e 10 -------------->port e 10 3com switch
port e 10 in the foundry belongs to vlan 2 and vlan 30 (tagged of course)
port e 10 in the 3com belongs to vlan 2 and vlan 30 (also tagged)
port 1 to 9, and port 11 to 40 of the 3com are untagged ports of vlan 2
port 40 to 50 are untagged ports of vlan 30
As you can see there is no physical port in vlan 1, cause I don't need it..The only way I can make it work (kind of) it's if I move one port to vlan 1 (lets say port 11) and then I cross connect port 11 with any untagged port of vlan 2.
The above method almost works ....the RTT of the ping starts in less than 10ms and keeps growing till it reaches 1.5 seconds. (I mean a ping to the managed IP, belonging to vlan 1 and generated from a host belonging to vlan 2).
Any help will be greatly appreciated,
