You must configure the following IP information to establish in-band connectivity to
the switch:
IP Address
Unique IP address for your switch. Each IP parameter is made up of four
decimal numbers. The numbers range from 0 to 255. The default for all IP
parameters consists of zeros (that is, 0.0.0.0).
Subnet Mask
The subnet mask for the LAN.
Default Gateway
Identifies the address of the default router if the switch 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
This is an additional parameter that you can configure. The following rules
apply:
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
Specifies if the burned-in MAC address or the locally-administered MAC
address should be used. The burned-in MAC address is the default MAC
address type.
Network Configuration Protocol Current
Specifies the network configuration protocol currently being used. Possible
values are:
v
BootP / Static DHCP: the switch periodically sends requests to a BootP
or DHCP server until a response is received.
v
None: the switch will be manually configured with IP information as
specified on the Network Connectivity Configuration Menu.
Network Configuration Protocol on next Reset
When you select BootP/Static DHCP (the default), the switch periodically
sends requests to a BootP or DHCP server until a response is received.
You must specify None, if you want to manually configure the switch with
the appropriate IP information. When this value is modified, you need to
issue a Save and then reset the switch in order for the new value to take
effect.
Web mode
Used to enable or disable access to the switch through the Web interface.
When enabled, you can login to the switch from the Web interface. When
disable is selected, you cannot login to the switch’s Web server. Specifying
Disable provides for more secure access to the switch. The default is
Enable.
Note: Disabling the Web interface will not disable Web sessions that are in
progress; no new Web sessions will be started.
Configuring serial port
The switch allows you to access the switch through the serial EIA 232 port. This
type of connectivity is called out-of-band connection. See “Chapter 2. Accessing the
switch” on page 19 for descriptions of ways to access the switch.
