077EEEE7 represents the ID block/ID number of the local PU

There are two Telnet servers in the device, the remote console and the TN3270E
Server. One IP address will be designated as the TN3270E Server address/port.
Telnets to this address/port will be tn3270, and will not get to the remote console.
The TN3270E configuration includes the

TN3270E config>

set command to

configure the IP address/port for the TN3270E Server.

Only one address can be specified as the TN3270E address.

v

Use of an interface address

There can be any number of addresses assigned to an interface. If the system
administrator does not want to lose the ability to Telnet to the router using an
existing interface address, an additional address (with a subnet mask which RIP
and OSPF will advertise) can be added to an interface. We recommend
designating an interface address as the TN3270E Server Address.

v

Use of the device id

For TN3270 purposes, this address is like an interface address.

v

Use of the internal address

This address is advertised over all dynamic routing protocols. It is also
continually reachable, whereas interface addresses are only reachable when the
interface is up. This address is not recommended as the TN3270E Server
Address, except in cases where reachability is guaranteed without respect to the
(up or down) state of any interface.

TN3270 LU Pooling

LU pooling is an enhancement to the TN3270E Server function that makes it easier
to configure some TN3270E Server networks. This function allows SNA LUs to be
grouped into named

pools

. TN3270E clients can then request a connection using

the pool’s name as an LU name. The TN3270E Server will then choose an LU from
the specified pool to service the client’s request.
