Chapter 1. Getting Started This chapter shows you how to get started with using the following components related to the IBM 2210 Nways Multiprotocol Router (2210) and the Multiprotocol Routing Services: v Router console terminals v Router software (Multiprotocol Routing Services) v Router software user interface The information in this chapter is d ...
IBM SC30-3681-08 - page 40

Local Consoles Local consoles are either directly connected by an EIA 232 (RS-232) cable, or connected via modems to the router . Y ou may need to use a local console during the initial software installation. After the initial setup connection, you can connect using T elnet, as long as IP forwarding has been enabled. (Refer to Protocol Conﬁgurati ...
IBM SC30-3681-08 - page 41

Remote Consoles Remote consoles attach to the router using a standard remote terminal protocol. Remote consoles provide the same function as local consoles, except that a local console must be used for initial conﬁguration if your IBM 2210 was not pre-conﬁgured at the factory . T elnet Connections The router supports both T elnet Client and Ser ...

The network management beneﬁts of emulated LANs (ELANs) come from increased ﬂexibility in handling moves, adds, and changes.

As long as ELAN memberships are retained, no recon ...

Overview of the LECS Function LE clients are not required to use the LECS, although it is recommended. If the LECS is not used, each LE client must be conﬁgured with the A TM address of the LES that serves its ELAN.

This ﬁeld can specify the upper bound on the size of a data frame that can be processed by the LE client, or it can be unspeciﬁed. The LECS cannot assign a client to an ELAN with a maximum frame size larger than that speciﬁed by the client. If the ELAN allows frames too large for the client to handle, the client cannot function on that ELAN. ...
IBM SC30-3681-08 - page 298

Sample Situations for Use of the LECS Assignment Policies The following section offers examples of various LECS assignment policies. A TM Address Policy The LECS permits two types of A TM address policy values. The ﬁrst type is a variable length A TM address preﬁx. For example, the policy value (3999999999999900000102, LES_A) means that all LE ...
IBM SC30-3681-08 - page 299

This setup requires conﬁguring the LE clients with the correct ELAN Name. v Use names for the LE clients Each LE client can be given its own name. For example, you could create the policy values (Joe, LES_A) and (Mary , LES_A). Then, the LE clients conﬁgured with these names would be directed to the same LES. This method requires conﬁguring t ...

v By default, ELANs use best-effort connections to connect to the BUS. For ELANs where BUS traff ic is heavy , better performance can be obtained by using reserved bandwidth connections to the BUS. The characteristics of the Multicast Send VCC between the LE client and the BUS can be controlled with TL Vs. v A TL V can be used to download the ELAN ...

Address Registration LE clients register LAN destinations with the LES to ensure uniqueness and to allow the LES to answer LE_ARP_REQUEST s, which LE clients issue to learn the A TM address associated with a particular LAN destination. Registrations include the LAN destination and the A TM address that the LE client associates with the LAN destinat ...

BUS processing requirements are increased and multicast frames must be transmitted twice (once on each Multicast Forward VCC).

The LECS retains a short-term memory of all client assignments so that it can alternately direct an LE client to a primary and backup LES. This simple heuristic makes the correct assignment in the nominal case of no failure and is self-correcting. At worst, the heuristic causes the LE client to repeat the conﬁguration phase of joining an ELAN. LE ...
