# SANbox2 Network Properties

Network properties define the switch identity on the Ethernet network, and can be configured using the Network Properties dialog. The Internet Protocol configuration identifies the switch on the Ethernet network. The SNMP configuration defines how authentication traps are managed.

Note: Since Read Community, Trap Community, and Write Community settings are like passwords, they are write-only fields; the current settings are not displayed.

IP Configuration Area

Network Discovery | Choose one of the following network discovery methods: RARP (Reverse Address Resolution Protocol) - Acquires the IP configuration from an RARP server. One RARP request is broadcasted. A maximum of three re-tries is attempted, each at 5 second intervals. If no IP address is obtained, the switch reverts to the previously configured IP address. Static - Uses the IP configuration parameters entered in the Switch Properties dialog. BootP - Acquires the IP configuration from a BootP server. DHCP (Dynamic Host Configuration Protocol) - Acquires the IP configuration from a DHCP server. If no satisfactory lease is obtained, the DHCP client attempts to use the previously configured lease. If the previous lease cannot be used, no IP address will be assigned to this switch in order to avoid an IP address conflict. The DHCP server must then be made available. Note: If a BootP or DHCP server is not available, the switch will boot. However, you will be unable to manage the switch through the Ethernet connection. To manage a switch under these circumstances, the connection must be made through the serial port. The switch will attempt to use a previously assigned valid lease. If no lease was ever assigned, the switch will attempt to use the previously assigned static IP address.
Subnet Mask | Subnet mask address for the Ethernet port. The default and PROM mode value is 255.0.0.0.
IP Address | Internet Protocol address for the Ethernet port. The default and PROM mode value is 10.0.0.1.
Gateway | IP gateway address. The default and PROM mode value is 10.0.0.254.

SNMP Configuration Area

The SNMP configuration defines how authentication traps are managed.

SNMP Proxy | Check this box to enable SNMP communication with other switches in the fabric.
Contact | Specifies the name (up to 32 characters) of the person who is to be contacted to respond to trap events. The default is “undefined”.
Read Community | Read Community Authentication. A write-only field; the value on the switch and the SNMP management server must be the same. The default value is Public.
Trap Community | Trap Community Authentication. A write-only field; the value on the switch and the SNMP management server must be the same. The default value is Public.
Proxy Enabled | Checkbox to enable or disable SNMP communication with other switches in the fabric.
Location | Specifies the name (up to 32 characters) for the switch location. The default is “undefined”.
Authentication Trap | Enables or disables the reporting of SNMP authentication failures. If enabled, a notification trap is sent to the configured trap addresses in the event of an authentication failure if incorrect community string values are used. The default value is False.
Write Community | Write Community Authentication. A write-only field; the value on the switch and the SNMP management server must be the same. The default value is Private.

SNMP Trap Configuration Area

The SNMP trap configuration defines how traps are set.

Trap Version | Specifies the SNMP version (1 or 2) with which to format traps.
Trap Address | Specifies the IP address to which SNMP traps are sent. A maximum of 5 trap addresses are supported. The default address for trap 1 is 10.0.0.254. The default address for traps 2–5 is 0.0.0.0. Note: Trap address (other than 0.0.0.0) and trap port combinations must be unique. For example, if trap 1 and trap 2 have the same address, then they must have different port values. Similarly, if trap 1 and 2 have the same port value, they must have different addresses.
Trap Enabled | Check box enabling or disabling that numbered trap. There are five trap tabs pages.
Trap Severity | Pull-down menu from which to choose the importance of the trap being set
Trap Port | The number of the port on which a trap is set

Enable Remote Logging (syslog) Area

Enable Remote Logging (syslog) | When enabled (check mark present), saves of the log information to a remote host that supports the syslog protocol
Logging (syslog) Host IP Address | When the Enable Remote Logging box is checked, the log entries are sent to the host IP address specified in this field. Log entries are saved in the internal switch log whether this feature is enabled or not. Note: To save log information to a remote host, you must edit the syslog.conf file and then restart the syslog daemon. The syslog.conf file on the remote host must contain an entry that specifies the name of the log file in which to save error messages. Add the following line to the syslog.conf file. A <tab> separates the selector field (local0.notice) and action field containing the log file path name (/var/adm/messages/messages.name). local0.notice <tab> /var/adm/messages.name
