Viewing/Changing switching methods on Cisco 3550 switch?

How do you view the default switching method for 3550?

ie, Cut-through, Fragment-Free, or Store and Forward

There was a command lower end switch IOS "show port system". Does this work for 3550?

Also, how do you change the switching method?

Thanks in advance :)

Hi,

If you view this : http://www.cisco.com/en/US/docs/switches/lan/catalyst3550/software/release/12.1_13_ea1/configuration/guide/swadmin.html

you can find that: " The switch always uses the store-and-forward method".

I hope this helps.

Best regards.

Massimiliano.

Hi,

As a matter of fact, all the current Cisco switches use store-and-forward (the complete data frame is received on the switch's buffer, a CRC is run, and if the CRC passes, the switch looks up the destination address in the MAC filter table), while cut-through and fragment free were historical technologies.

HTH,
