Q: Does the FEP-4600 support DLSw connections for PU2 traffic to remote sites?
A: Yes. The FEP-4600 offers two different options. Like a 3745, you can have an
external DLSw router providing the encapsulation function. The FEP-4600 can
also provide the DLSw function internally providing IP-only traffic through an
Ethernet port to tie directly into your IP network.
Q:
What all types of remote connections are supported through the FEP-4600’s XCA
interface (allowing Switched PU definitions to be used)?
A: The FEP-4600 supports XCA connectivity to PU2.0 and PU2.1 devices attached
through Token Ring, Ethernet, and SDLC interfaces.
Q:
Does the FEP-4600 support EMIF to allow multiple LPARs to share a single
CHPID?
A: Yes and no. EMIF is supported completely for PU2 traffic, but not for PU4
traffic. Although you can configure PU4 connections through shared CHPIDs,
you will likely run into intermittent problems. Using ESCON directors you can
direct traffic from multiple CHPIDs through a single ESCON connection to a
FEP-4600 with success.
Q:
Does the FEP-4600 support FICON connections?
A: Yes
Q:
What does the FEP-4600 look like to my host through a FICON link to support
PU4 connections?
A: The FEP-4600 looks like a channel-to-channel connection (TYPE=FCTC).
Q:
Can the FEP-4600 provide channel-to-channel connections between an ESCON
channel and a FICON channel?
A: Yes. Both same VTAM network and SNI connections can be supported this way.
