Configuring IP Parameters
The network management station is configured for IP using the TCP/IP stack
utilities. To configure a device for IP, you typically connect to the device’s
console port and use the console port interface. (Refer to the device’s instal-
lation manual for more information.)
Before you configure the network management station and manageable
devices for IP, make a list of all the devices on the network and what their IP
addresses will be.
Note: Make sure that every device has a unique IP address. Make sure
that all devices on a given IP network number have the same subnet
mask.
The IP configuration parameters are described below.
IP Address . The IP address of the hub, bridge, or switch is written in the
format X.X.X.X, where each X is a decimal number between 1 and 254. Every
IP address on a network must be unique.
The default value, 0.0.0.0, disables IP communications. Use the default value
only if you are not going to manage the device with HP Hub & Switch
Management and you want to disable IP communications for that device.
Subnet Mask. The bit mask defines which portion of the IP address is the
subnet address and is written in the format X.X.X.X. The default value is
automatically generated and depends on the class of IP address that you
entered. See your network administrator for the subnet mask address. All
devices on a given IP network number must use the same subnet mask
address.
Primary Default Router . The routing IP address of the nearest router in
your network. The default is 0.0.0.0.
Backup Default Router. The IP address of the router to use when the
primary default router is inaccessible. The default value is 0.0.0.0. If there is
no backup router and no primary default router, use the default.
Time To Live . The number of IP routers a packet is allowed to cross before
the packet is discarded. The default value is 32. Increase this value if the hub,
bridge, or switch is managed from a network management station that is more
than 32 routers away. The maximum allowable value is 255.
Note: For selected devices, such as the HP J2980A AdvanceStack 10/
100 LAN Switch-16, you must preconfigure the SNMP community
