Hi ,
On a 4507R Sup 4 redundant, IOS version 12.2-44.SG
I have an WS-X4548-GB-RJ45 in slot 7.
On this card are connected Servers (and Vmware) in access mode L2.
On all interface slot 7 who is in up/up state the output drops counters increase in gust. why ?
What means the output drops ?
.
In slot 3 and 4 I have the other switch attachement in trunk mode L2, there is no output drops counter problem.
But I see that on slot 5 and 6 I have WS-X4232-GB-RJ and WS-X4148-RJ card, with other server who has the counter output drops increase, but only on some interface.
In general the users complain about deceleration network.
I test to remove the flow control on a server cluster interface on switch side and server side but the problem persist.
Any idea ? Which can be the problem ?
