Mobile WiMAX RAS SPI-2213 System Description/Ed.02

Ethernet/VLAN Interface Function

The SPI-2213 provides the Ethernet interface and supports the static link grouping function,

Virtual Local Area Network (VLAN) function and Ethernet CoS function under IEEE

802.3ad for the Ethernet interface. At this time, the MAC bridge function defined in IEEE

802.1D is excluded.

The SPI-2213 enables several VLAN IDs to be set in one Ethernet interface and maps the

DSCP value of IP header with the CoS value of Ethernet header in Tx packet to support

Ethernet CoS.

2.3.4 Auxiliary Device Interface Function

The SPI-2213 provides the Ethernet interface to connect auxiliary devices and allocates IP

addresses by operating as a DHCP server for the auxiliary devices. In addition, the SPI-

2213 provides the traffic path to transmit/receive the maintenance traffic between an

auxiliary device and the remote auxiliary device monitoring server.

If the auxiliary device uses a private IP address, the SPI-2213 carries out the NAT function

to change the address into a public IP address (i.e., the IP address of the SPI-2213) for the

communication with an external monitoring server.

2.3.5 Maintenance Function

The SPI-2213 interworking with the management system carries out the following

maintenance functions: system initialization and restart, management for system

configuration, management for the operation parameters, failure and status management for

system resources and services, statistics management for system resources and various

performance data, diagnosis management for system resources and services and security

management for system access and operation.

Graphic and Text-based Console Interface

WSM manages the entire Mobile WiMAX system by using Database Management System

(DBMS) and SPI-2213 interworks with this WSM. In addition, ACR interworks with the

console terminal for directly accessing the NE as well as WSM by operator to perform the

operation and maintenance function.

For operator’s convenience and working purpose, the operator can select graphic-based

console interface (Web-based Element Maintenance Terminal, Web-EMT) or text-based

console interface (Integrated Management Interface Shell, IMISH).

The operator can access the console interface with no separate software and log in to Web-

EMT through Internet Explore and IMISH through Secure Shell (SSH) on the command

window.

The operator can carry out the retrieval and setup of the configuration and the operation

information and monitoring about faults, status and statistics via console terminal.

However, the operator can carry out grow/degrow of resources and setting of the neighbor

list and paging group which have correlation between several NEs only via the WSM.
