I have 2 servers on the same switch. I'm losing 5% of packets on ~16k pings between the two.
Below is my nasty ASCII diagram of the configuration of the network, all machines have a single interface.
a b | | -- S1 -- | S2 | S3 | c
a = Sun Netra 240
b = Dell 2950
c = my machine
S1 - S3 = 3 x Cisco Catalyst 2960G
pings from a -> b lose 5% data
pings from b -> a lose 5% data
pings from c -> a lose 0 data
pings from c -> b lose 0 data
I can't think of a reason that I'd lose packets going between ports on the same switch, when I didn't lose data coming from a different switch but still using the same port.
Can anyone throw any ideas my way please?
