Configuring IP Addressing, Interface Access, and System Information

IP Configuration

Timep Operation. Use this optional parameter if you want the switch to get its time information from another device operating as a Timep server. In its default Timep configuration, the switch attempts to get a Timep server address from a DHCP server. Other configuration options are to manually assign a Timep server address or to disable the Timep server feature.

Just Want a Quick Start?

If you just want to give the switch an IP address so that it can communicate on your network, or if you are not using VLANs, HP recommends that you use the Switch Setup screen to quickly configure IP addressing. To do so, do one of the following:

■Enter setup at the CLI Manager level prompt.

HP2512# setup

■Select 8. Run Setup in the Main Menu of the menu interface.

For more on using the Switch Setup screen, see the Installation and Getting Started Guide you received with the switch.

 

IP Addressing with Multiple VLANs

 

In the factory-default configuration, the switch has one, permanent default

 

VLAN (named DEFAULT_VLAN) that includes all ports on the switch. In this

 

state, when you assign an IP address and subnet mask to the switch, you are

 

actually assigning the IP addressing to the DEFAULT_VLAN. You can rename

 

the DEFAULT_VLAN, but you cannot change its VLAN ID number (VID) or

 

remove it from the switch.

 

 

N o t e s

■ If multiple VLANs are configured, then each VLAN can have its own IP

 

address. This is because each VLAN operates as a separate broadcast

 

domain and requires a unique IP address and subnet mask. A default

 

gateway (IP) address for the switch is optional, but recommended. The

 

primary VLAN is the VLAN used for stacking operation, as well as for

 

determining the default gateway address, (packet) Time-To-Live (TTL),

 

and Timep via DHCP or Bootp. (Other VLANs can also use DHCP or BootP

 

to acquire IP addressing. However, the switch’s gateway, TTL, and TimeP

 

values will be acquired through the primary VLAN only. In the default

 

configuration, the default VLAN (named DEFAULT_VLAN) is the switch’s

 

primary VLAN.However, with multiple VLANs assigned to the switch, you

 

can select another VLAN to function as the primary VLAN. For more on

 

VLANs, refer to “Port-Based Virtual LANs (Static VLANs)” on page 9-50.
