I have a production 3030 that plug in to a VLAN on a cat 5500 and I loose tcp/ip to the private interface at lease once a day. I have looked at the 3030 MIB2 ethernet stats and there are no errors or colisions and the 3030 private and the cat 5500 vlan port show UP. I have a 3015 on the same cat5500 vlan that has no errors so, I have switched ports and cat5e cable with the 3030.
any Ideas??
