RS-232 (serial port)
The fibre channel subsystem of your Scalar 218FC is configured as follows:
1 SCSI F/W interface
1 Gigabit Fibre Channel interface (optical)
1 10BaseT Ethernet Port
1 RS-232 Serial Port
The serial and Ethernet ports are used primarily for fibre channel subsystem configuration and management.
(TCP/IP requests may also be serviced over the Fibre Channel ports (in-band) in future releases.) A
discussion of each of these ports and its associated MIB data follows. Configuration information for each
interface is contained in the following section as well.
Fibre Channel
Fibre Channel data reported includes frame and packet information, upper layer protocol (ULP) type (FCP or
IP), and other Fibre Channel-specific information. Draft MIBs for Fibre Channel N_Ports and F_Ports are in
the public realm.
ADIC proposes to support portions of two standard Fibre Channel MIBs as well as an ADIC private MIB.
The ADIC private MIB includes:
Groups for Fibre Channel Configuration
FC N_Port Physical Table
FC N_Port Statistics
SCSI-to-FC Mapping
FC-to-SCSI Mapping
SCSI
SCSI is not generally an SNMP managed protocol. The ADIC MIB, however, gathers SCSI information for
management purposes. This ADIC specific MIB provides information about the following:
number of I/O operations per bus
number of disconnects
abort count
total data counts in bytes
bus resets
vital product data from Inquiry command for each SCSI device
This information can be found in the SCSIStatisticsTable and the SCSIProductData Groups of the ADIC
private MIB.
Ethernet and Serial Interfaces
The Ethernet interface is used for configuration and management, so total traffic flow is relatively low. The
basic Ethernet configuration items are found in the Management Interfaces Table.
The serial port is provided for user configuration. The serial port baud rate will be kept in the Management
Interfaces Table.
