vlan routing issue
Hi,
I've got an issue with integrating a further switch to a vlan infrastructure. The situation is: switch A and switch B with different vlans. Switch A (192.168.123.250): Port 1 = tagged VLAN 123 = uplink switch C (HP procurve 1910) Port 24 = tagged VLAN 123,untagged VLAN 1 = uplink switch B vlan interface configured Switch B (192.168.123.249): Port 24 = tagged VLAN 123,untagged VLAN 1 = uplink switch A vlan interface configured Switch C (192.168.123.248): Port 24 = tagged VLAN 123,untagged VLAN 1 = uplink switch A Port 1-10 = untagged VLAN 123 vlan interface configured Communication between switches A and B is okay, I can ping all devices and all interfaces. But switch C (interface) is not reachable, neither from A nor B! IP Routing on Switch C is: 192.168.123.0 192.168.123.248 192.168.123.248 127.0.0.1 Did I forget something? Anyone who can shed some light?.... |
Network look like there is a loop. Is spanning tree on? The port could be shut down automatically.

spanning tree is on
where is the loop? |
Port1 and VLAN 123 on switch A -> switch C -> port24 and VLAN123 on switch C -> Switch A
|
I'm afraid I'm blind....the connection is:
tagged: C/Port24 ---------- A/Port1 tagged: A/Port24 ---------- B/Port24 untagged C/Port1-10 untagged A/Port2-10 untagged B/Port1-10 |
