Bootp Automatic Ip Configuration/Mac Address; Autosensing And Autonegotiation - Nortel BayStack 450-24T Using Manual

BootP Automatic IP Configuration/MAC Address

The BayStack 450 switch has a unique 48-bit hardware address, or MAC address,
that is printed on a label on the back panel. You use this MAC address when you
configure the network BootP server to recognize the BayStack 450 switch BootP
requests. A properly configured BootP server enables the switch to automatically
learn its assigned IP address, subnet mask, IP address of the default router (default
gateway), and software image file name.
When the switch is participating in a stack configuration, a Stack MAC address is
assigned automatically during the stack initialization. The base unit's MAC
address, with an offset, is used for the Stack MAC address.
For example, if the base unit's MAC address is:
00-00-82-99-44-00
and the offset is:
1F
then the Stack MAC address becomes:
00-00-82-99-44-1F
If another unit in the stack is assigned as the base unit, the MAC address of the
new base unit (with offset) now applies to the stack configuration. The original
stack IP address still applies to the new base unit.
For an example of a BootP configuration file, see Appendix H, "Sample BootP
Configuration File."

Autosensing and Autonegotiation

BayStack 450 switches are autosensing and autonegotiating devices. The term
autosense refers to a port's ability to sense the speed of an attached device. The
term autonegotiation refers to a standardized protocol (IEEE 802.3u) that exists
between two IEEE 802.3u-capable devices.
Autonegotiation allows the BayStack 450 switch to select the best of both speed
and duplex modes.
