Flash memory storage
Switch software image storage
The BayStack 380 Switch uses flash memory to store the switch software image.
The flash memory allows you to update the software image with a newer version
without changing the switch hardware (see “Software Download screen” on
page 164). An in-band connection between the switch and the TFTP load host is
required to download the software image.
Configuration parameters storage
All configuration parameters are stored in flash memory. These parameters are
updated every 60 seconds (if a change occurs) or whenever a reset command is
executed.
MultiLink Trunking
The MultiLink Trunking feature allows you to group multiple ports, two to four
together, when forming a link to another switch or server, thus increasing
aggregate throughput of the interconnection between two devices, up to 8 Gb/s in
full-duplex mode. The BayStack 380 Switch can be configured with up to six
MultiLink Trunks.
For more information about the MultiLink Trunking feature, see “MultiLink
Trunk Configuration Menu screen” on page 136.
Warning: Do not power off the switch within 10 seconds of changing
any configuration parameters. Powering down the switch within 10
seconds of changing configuration parameters can cause the changed
configuration parameters to be lost.
