Hi this is Moench6387 (had problems with my community account) Firmwareupdate didn't help to solve my problem. But I got the problem resolved by removing the vlan subnet associations. Don'T really get it, because the correct vlans were shown on the ports. Still now it works :)
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 errorsFCS-Err: FCS errorsXmit-Err: Total transmit errorsRcv-Err: Total packets received with MAC errorsUnderSize: Fragments/undersize receivedOutDiscard: Total transmit packets discarded Port Align-Err FCS-Err Xmit-Err Rcv-Err UnderSize OutDiscard--------- ---------- ---------- ---------- ---------- ---------- ----------Gi1/0/1 0 0 0 0 0 0Gi1/0/2 0 0 0 0 0 0Gi1/0/3 0 0 0 0 0 0Gi1/0/4 0 0 0 0 0 0Gi1/0/5 0 1 0 1 0 499346Gi1/0/6 0 0 0 0 0 12298Gi1/0/7 0 0 0 0 0 8284Gi1/0/8 0 0 0 0 0 8190094Gi1/0/9 0 0 0 0 0 0Gi1/0/10 0 0 0 0 0 0Gi1/0/11 0 0 0 0 0 380481Gi1/0/12 0 0 0 0 0 0Gi1/0/13 0 0 0 0 0 0Gi1/0/14 0 0 0 0 0 0Gi1/0/15 0 0 0 0 0 0Gi1/0/16 0 0 0 0 0 0Gi1/0/17 0 0 0 0 0 0Gi1/0/18 0 0 0 0 0 0Gi1/0/19 0 0 0 0 0 503511Gi1/0/20 0 0 0 0 0 503472Gi1/0/21 0 0 0 0 0 503521  Can anybody help me? Thanks a lot in advance! Arne
No ICMP between vlans and a lot of Discarded packets
