Hello
I would like to ask general question about switch speed experience.
How can I increase speed in switch port?
The speed of the switch port is limited by the hardware. Make sure you are running a nic capable of the maximum switchport speed and that they are configured to be the maximum speed either by negotiation or manually. Most switches now days are 100mbps or 1000mbps. If it is too slow for you, try upgrading both the end point and replacing the switch to 10G. If you give us a make/model number, it is much easier to tell you what your switch can do.
ls it to combine more than one port? Any other solution?
Yes, there are a few ways and they vary by vendor, but the most common way is LACP etherchannel. http://en.wikipedia.org/wiki/Link_aggregation#Link_Aggregation_Control_Proto...
In combing ports, what are the advantages and disadvantages?
The advantage is increased bandwidth (naturally), also increased redundancy. Unfortunately LACP does not give a true "2gbps" capability, it simply load balances between the two links based on various factors. So a single connection will only go up to 1gbps, even if the nic connecting it to the switch is a 10gbps connection. However for switch uplinks this is rarely a problem (so long as the correct load balancing algorithm is selected) as multiple hosts are connected at 1gbps trying to go upstream.
Any info and experience. Thank you for your sharing.
This is a 60 second overview and there is much more to this topic than I have said, but hopefully this will get you on your feet. -=Tom Donnelly -- Using Opera's revolutionary email client: http://www.opera.com/mail/
