Hi, I'm debugging for some time on a problem with ARP resolution in our datacenter environment. I found out that ARP requests are not forwarded on one particular 10GE trunk interface, which is therefore unusable. With a monitor and wireshark I see the ARP request coming in and going out on all other ports, but not on Te1/0/2. Actually there are no L2 broadcast packets at all on this port.
We already made a software upgrade on the switch, with no improvement, now we run: WS-C3750E-48TD 12.2(52)SE Has anybody an idea what is wrong ? Port config is: interface TenGigabitEthernet1/0/2 switchport trunk encapsulation dot1q switchport trunk native vlan 900 switchport mode trunk switchport nonegotiate spanning-tree cost 200000 Christian --------------------------------------------- PIRONET NDH Datacenter GmbH Christian Schuler http://www.pironet-ndh.com/itk _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
