Use the following DIALNO format for host-initiated connections
to peripheral devices connected through the IBM® 3172 Nways Interconnect Controller (
aa,
bb,
and
cccccccccccc are hexadecimal):
DIALNO=aabbcccccccccccc
- aa
- A 2 digit place-holder. It has no meaning in the IBM 3172 Nways Interconnect Controller environment.
- bb
- The service access point (SAP) address of the terminal. It must
be a multiple of 4.
- cccccccccccc
- The medium access control (MAC) address for the peripheral device
on the local area network.
Note: - You cannot code 000000000000 for the last 12 digits (MAC address)
on the DIALNO operand on the PATH definition statement.
- If the PU is attached to a LAN through the IBM 3172 Nways Interconnect Controller using an 8209
LAN bridge, the MAC address must be coded differently. Because the
8209 will flip the bits in every byte of the MACADDR, the MACADDR
should be coded in inverted order in the DIALNO.
- Certain levels of NCP do not support hexadecimal digits X'A'–X'F' as
part of the MAC address.
