•
Name: LAN1/LAN2. LAN1 corresponds to the port labeled CH-1 on the back of the RTX-IR, while
LAN2 corresponds to the port labeled CH-2.
•
DHCP: Yes/No – Click on the button below “Yes” or “No” to configure the IP settings for each
data port. Refer to section _____ for more information.
•
IP address: Displays the IP address currently in use by each data port.
•
Netmask: Displays the subnet mask being used by each data port.
•
Gateway: Displays the IP gateway (in a DHCP network, the IP of the router)
•
MTU (Maximum Transmission Unit): Displays the MTU size being used by each data port. The
range of MTUs allowed are 1500, 2000, and 3900. Default is 1500. To change the MTU, click
the button below the current MTU number of the LAN port that you wish to alter. This will bring
up a screen with a dropdown box that can be used to change the MTU.
Note: Changing the MTU will cause the RTX-IR to function improperly if the switch and network
card are not configured appropriately.
•
MAC address: Displays the MAC address of each data port.
•
Link: Up/Down – Displays the status of each data port. If an Ethernet cable is connecting the
RTX-IR to a network or computer, the Link will display “up.”
6.5.3 Node
The Node option displays the RTX-IR’s entity name, which will be seen by the iSCSI initiator, and allows
you to toggle CHAP (Challenge Handshake Authorization Protocol) on or off. For more information on
CHAP, see 6.5.5.
CHAP is disabled by default. To turn on CHAP, click the button in the Auth column. This will bring up a
screen with a dropdown box. Click the dropdown box and select CHAP, then click the Confirm button.
After turning on CHAP authentication, you must set up at least one CHAP account (see section 6.5.5).
6.5.4 Session
The session function allows you to view information on a session initiated by an iSCSI initiator application
(see Chapter 7.)
6.5.5 CHAP account
CHAP is a common iSCSI authentication method. When CHAP is enabled, the RTX-IR will require
authentication at login through the iSCSI initiator (see Chapter 7). Authentication also occurs at various
times during the connection, by way of transferring the user name, initiator password (also called initiator
secret), and target password (also called target secret). RTX-IR uses the same value for initiator secret
and target secret. For added security, the authentication information is hashed and a token is sent
instead of the information itself.
