  • Page 22: Configuration Overview

    Configuring SCADA Bridges 3.1.1 Configuring the IOM and Card Slot The 7705 SAR card slot ID is always 1 and the card type for the IOM is always iom-sar. On the 7705 SAR-8 and 7705 SAR-18, the CSM, which can only be installed in slot A or B of the chassis, does not need to be provisioned.

  • Page 23: Configuring Adapter Cards And Modules

    A chassis slot is a physical slot designated with an MDA ID. On the 7705 SAR-8, the MDA ID is from 1 to 6. On the 7705 SAR-18, the MDA ID is from 1 to 12 for the MDA slots and from X1 to X4 for the XMDA slots. An adapter card is provisioned when a card designated from the allowed adapter card types is inserted.

  • Page 24: Maximum Number Of Adapter Cards In A Chassis

    Note: Unless otherwise specified, references to adapter cards with multiple versions include all versions of the cards. A maximum of six adapter cards can be installed in the 7705 SAR-8 chassis. The following adapter cards are supported: • 2-port 10GigE (Ethernet) Adapter card (maximum of 4 in a 7705 SAR-8 with CSMv2) •...

    The 7705 SAR supports network access control over client devices on an Ethernet network using the IEEE 802.1x standard. 802.1x is a standard for authenticating Ethernet devices before they can access the network. In the case of the 7705 SAR, authentication is performed using Extensible Authentication Protocol (EAP) over LAN (EAPOL).

    Note: OTP is one of many authentication mechanisms that are available for use between the supplicant and the authentication server. These authentication mechanisms (protocols) are transparent to the 7705 SAR. The authenticator initiates the procedure when the Ethernet port becomes operationally up by sending a special PDU called an EAP-Request/ID to the supplicant.

    After sending an EAP-Failure message, the authenticator puts the supplicant in an unauthorized state, waits for the number of seconds defined by the quiet-period timer, then continues searching for supplicants to authenticate.
