Hello to everyone,
I have a stack of 3* N3048 Switches (running config attached). There are different vlans configured. The clients are connected to access mode ports. The Gateway for all vlans is the same (our firewall).
My problem is, that when a client in vlan 1 tries to ping a client in vlan 10 (on different Switch) it receives timeout. Its the same for the other way.
On our Gateway I can see on both vlan interfaces echo request and echo reply when vlan 1 tries to ping vlan 10. When i ping from vlan 10 from another switch to vlan 1 client i can only see echo request on both vlan interfaces on the gateway.
On all other switches there is no problem pinging in both directions from the clients.
I can see a lot of discarded packets (out) on the client ports:
SWBEGASIEMENS01#show interfaces counters errors
Align-Err: Alignment errors
FCS-Err: FCS errors
Xmit-Err: Total transmit errors
Rcv-Err: Total packets received with MAC errors
UnderSize: Fragments/undersize received
OutDiscard: Total transmit packets discarded
Port Align-Err FCS-Err Xmit-Err Rcv-Err UnderSize OutDiscard
