Configuring iLO 2 63
• Subnet Mask is the subnet mask of the iLO 2 IP network. If DHCP is used, the Subnet Mask is
automatically supplied. If not, enter the subnet mask for the network.
• Gateway IP Address displays the IP address of the network gateway. If DHCP is in use, the Gateway
IP Address is automatically supplied. If not, enter the network gateway address.
• iLO 2 Subsystem Name is a name used by the iLO 2 subsystem. If DHCP and DNS are configured
correctly, this name can be used to connect to the iLO 2 subsystem instead of the IP address. See
"iLO 2 subsystem name limitations (on page 63 )" for more information.
• Link controls the speed and duplex of the iLO 2 network transceiver. The current link speed of the
primary dedicated iLO 2 NIC can be highlighted. Link settings include the following:
o Automatic (default) enables iLO 2 to negotiate the highest supported link speed and duplex when
connected to the network.
o 100Mb/FD forces a 100-Mb connection using full duplex.
o 100Mb/HD forces a 100-Mb connection using half duplex.
o 10Mb/FD forces a 10-Mb connection using full duplex.
o 10Mb/HD forces a 10-Mb connection using half duplex.
If autosense is disabled, the network switch should match the iLO 2 settings to prevent iLO 2 access
issues.
iLO 2 subsystem name limitations
The iLO 2 subsystem name represents the DNS name of the iLO 2 subsystem. For example, ilo instead of
ilo.hp.com. This name can only be used, if DHCP and DNS are configured properly to connect to the
iLO 2 subsystem name instead of the IP address.
• Name service limitations—The subsystem name is used as part of the DNS name and WINS name.
However DNS and WINS limitations differ:
o DNS allows alphanumeric and hyphen. WINS allows alphanumeric, hyphen and underscore.
o WINS subsystem names are truncated at 15 characters, DNS are not.
If you require underscores, they can be entered in RBSU or using the iLO 2 scripting utility.
NOTE: Name service limitations also apply to the domain name.
To avoid name space issues:
o Do not use the underscore character.
o Limit subsystem names to 15 characters.
o Verify you can PING iLO by IP address and by DNS/WINS name.
o Verify NSLOOKUP correctly resolves the iLO network address and that there are no namespace
conflicts.
o Verify DNS and WINS both correctly resolve the name (if you are using both).
o Flush the DNS name if you make any name space changes.
