For some reason it seems to take atleast 30 seconds for clients to be allocated with an IP address on the network. The switches are Cisco SGE-2000 Managed, any ideas as to possible causes of the slowness or settings which could be causing this?
Do you have spanning tree on and have you made sure to set the spanning tree mode to portfast.
Image 5 STP operation mode.
Image 5 set the STP to portfast. Was it a company that did the setup and did he do any documentation??
Chris you beat me too it! lol
Contractor - no documentation. Wasn't my call on his involvement -.-
STP Operation Mode Options: Classic, Rapid or Multiple?
Ring him and demand documentation...any contractor or network engineer worth his salt would do documentation with their work.
Rapid, same thing with a different name.
