updates and additional info
2 environments, office and production at datacenter Both environments have Cat-5e cables, a cable was replaced when it tested as bad with Broadcom's cable testing, and some others cables have been switch out during trial and error troubleshooting Both environments have HP ProCurve gigabit switches Office environment has Cisco 861w router which spec sheets say has 4 100mbps ports Production environment has Cisco ASA 5510 router which has a mixture of gigabit and 100mbps ports. I am currently looking into what ports are in use.... Ok, the switch is reporting gigabit connection to router. note: I do not know how a 100mbps router port affects nic modes if there is a gigabit switch between them
This has been a recurring issue for us both on our office network and production. It rarely matters since normal traffic rarely comes close to utilizing 100mbps but when doing vmware conversions it is particularly annoying for it to take 8 hours instead of maybe 2 due to this limitation. My laptop and one of our office servers are showing as gigabit on our switch and we are seeing such speeds, however another server and NAS we are testing goes down to 100mbps mode when going through our primary office gigabit switch by way of wall drops (same wall plate as laptop). When we hook up the NAS to a local "desktop" gigabit switch it switches to 1000mbps mode and tests as such speeds to the laptop. In production only half of the nics report as 1000mbps though they all should. Any insight into why this might happen or what should be taken into account when troubleshooting would be appreciated.
