You must configure the following IP information to establish in-band connectivity
(access through SNMP, Telnet, and Web interfaces) with the 8275-416 :
IP Address
Unique IP address of your 8275-416 . Each IP parameter is made up of
four decimal numbers. The numbers range from 0 to 255. The default for all
IP parameters are
zeros (that is, 0.0.0.0).
Subnet Mask
Specifies the subnet mask for the LAN.
Default Gateway
If the 8275-416 is a node outside the IP range of the LAN.
Burned-in MAC Address
The burned-in MAC address is the default MAC address used.
Locally Administered MAC Address
A locally administered MAC address for the 8275-416 is an additional
parameter that you can configure. The following rules apply when specifying
a locally administered MAC address:
v
Bit 6 of byte 0 (called the U/L bit) indicates whether the address is
universally administered (B‘0’) or locally administered (B‘1’).
v
Bit 7 of byte 0 (called the I/G bit) indicates whether the destination
address is an individual address (B‘0’) or a group address (B‘1’).
v
A locally administered address must have bit 6 On (B‘1’) and bit 7 Off
(B‘0’).
MAC Address Type
The burned-in MAC address is the default MAC address type.
Concepts About Making Configuration Changes
This section provides key concepts about making configuration changes, getting the
changes put into effect, and retaining the changes across a power cycle of the
8275-416 .
This chapter provides you specific information about making configuration changes
using the Terminal interface, Web interface, and the SNMP interface.
Making Configuration Changes
Configuration changes are made by entering data for one or more items.
Error checking is done on the data entered to ensure that it is valued before it is
processed, When the check is done and the result depends on the method used to
initiate the change.
Configuration changes made by one user are also seen by other users when the
same data is requested. Be aware that information displayed may be old data if the
latest information is not requested prior to making any changes.
Processing Configuration Changes
Once you make a configuration change and it is accepted, the change is not put
into effect until you issue an APPLY command. Apply makes the changes take
