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.
