How do I check my Dell PowerConnect switches for internal latency?
Posted on 2009-07-09
I'd recently filed a support request with WatchGuard regarding my server. Support has stated the following:
Finally, I am seeing alot of the following types of log messages.
2009-07-09 10:03:22 Deny 10.0.0.247 184.108.40.206 60941/tcp 25 60941 1-Internal unknown TCP RST packet without an associated connection, firewall drop 40 128 (internal policy) tcpinfo="offset 5 R 270263463 win 0" rc="104" Traffic
This generally means there is some sort of internal network latency causing packets to arrive out of order to the firebox.
You may want to check your switches for any broadcast storms etc, that may cause internal network latency.
My question: How exactly do I check my network for broadcast storms that may cause internal network latency?
