Configuring IP Addressing
IP Configuration
How IP Addressing Affects Switch Operation
Without an IP address and subnet mask compatible with your network, the
switch can be managed only through a direct terminal device connection to
the Console RS-232 port. You can use direct-connect console access to take
advantage of features that do not depend on IP addressing. However, to realize
the full capabilities ProCurve proactive networking offers through the switch,
configure the switch with an IP address and subnet mask compatible with
your network. The following table lists the general features available with and
without a network-compatible IP address configured.
Table 8-1. Features Available With and Without IP Addressing on the Switch
Features Available Without an IP Address Additional Features Available with an IP Address and
Subnet Mask
• Direct-connect access to the CLI and the menu interface.
• DHCP or Bootp support for automatic IP address
configuration, and DHCP support for automatic Timep
server IP address configuration
• Multiple Spanning Tree Protocol
• Port settings and port trunking
• Console-based status and counters information for
monitoring switch operation and diagnosing problems
through the CLI or menu interface.
• VLANs and GVRP
• Serial downloads of software updates and configuration
files (Xmodem)
•Link test
• Port monitoring
• Password authentication
• Quality of Service (QoS)
• Authorized IP manager security
• Web browser interface access, with configuration,
security, and diagnostic tools, plus the Alert Log for
discovering problems detected in the switch along
with suggested solutions
• SNMP network management access such as
ProCurve Manager for network configuration,
monitoring, problem-finding and reporting, analysis,
and recommendations for changes to increase control
and uptime
• TACACS+, RADIUS, SSH, SSL, and 802.1X
authentication
• Multinetting on VLANs
• Telnet access to the CLI or the menu interface
•IGMP
• TimeP and SNTP server configuration
• TFTP download of configurations and software
updates
• Radius
• Ping test
