These filters can be activated and prioritized at both the bridge level and the port level to provide even greater control over your network traffic.

Comes with an easy-to-learn, easy-to-use graphical configuration program to simplify the task of configuring and managing the bridge module.

Management of the ATM LAN Bridge module is done using SNMP. The SNMP agent within the module supports various MIBs.

Note

The SNMP agent in this module is accessible via IP over any of the ATM or LAN ports. Since the ATM port supports only LANE or IBMLE, any ATM-attached management station must support LANE or IBMLE. This implies that ATM-attached stations using Classical IP over ATM (RFC 1577) cannot communicate with this module directly over ATM. However, an ATM router, such as the IBM Multiprotocol Switched Services Server, can interconnect ELANs running CIP and LANE, and provide SNMP access at the IP layer.

4.7.1.1 LAN Ports

The ATM TR/Ethernet Bridge Module has four LAN ports that can be configured (via the configuration program) to be used either as token-ring or as Ethernet ports.

Ports 1 and 3 on the module are always accessed via an RJ-45 interface for both token-ring and Ethernet.

Ports 2 and 4 can be accessed via the following interfaces:

•

•

An RJ-45 interface that can be used by token-ring or Ethernet

An AUI interface that can be used by Ethernet only

4.7.1.2 ATM Port

The ATM port on the ATM-LAN bridge does not have an external interface and communicates with the switch-on-a-chip and the 8285 ATM Control Point via the ATM backplane in the 8285 Expansion Chassis. The ATM interface complies with UNI 3.0 specifications.

4.7.1.3 RS-232 Console Port

In addition to the LAN ports, the ATM TR/Ethernet Bridge Module has an RS-232 console port (also known as a service port). The service port enables you to connect a workstation to the ATM TR/Ethernet Bridge Module to load new configuration, microcode, etc.

Note: After the initial configuration, you can also access the ATM TR/Ethernet Bridge Module inband through LAN or ATM ports to load new configuration, microcode, etc.
