Vanguard 7300 Port Configuration
Vanguard 7300
LLC-SDLC LAN
Ports To run LLC-SDLC (SLAC) on a Vanguard 7300 Series router, you must use the first
two Ethernet ports, the lowest numbered ports in the node. For example, for a
Vanguard 7300 running LLC-SDLC, the conversion ports have to be the first two
Ethernet ports on the MPC750 CPU card, which are:
• The on-board port labelled 10/100 BaseT (port number 101)
• The first PMC (PMC) Ethernet port (port number 151)
If you do not have a CPU PMC, the second Ethernet port would be the first Carrier
Expansion Card Ethernet port in that card’s PMC Slot 1.
The first two Ethernet ports on a IBM750FX CPU card are:
• ETH 1 (port number 101)
• ETH 2 (port number 103)
SLAC information is assigned to two system tables that are logically associated with
the first two physical Ethernet ports on the Vanguard 7300. The system tables are the
First Ethernet Station Table and the Second Ethernet Station Table, as shown in
Figure 4-7. Each table can contain up to 1000 LLCs. If you use any Ethernet port
other than the first two, the SLAC data is neither recognized nor reported.

BSC 3270-to-SNA
Conversion BSC 3270-to-SNA Conversion is supported on the Vanguard 7300 Series. The BSC
3270-to-SNA Conversion allows banks and ATM network providers to retain BSC
3270-attached ATMs while providing a LAN attachment at the host. The BSC 3270-
to-SNA converts the upper layers of SNA and the LLC2 data link control (layer two)
protocol in the host Vanguard 7300 Series node to Display System Protocol (DSP)
for transport within Frame Relay (Annex G) or X.25.
The total number of devices supported for BSC 3270-to-SNA conversion on a
Vanguard 7300 are 2,000. The maximum number of SLAC stations supported for
BSC LU devices are 100.
For more information, refer to the BSC 3270-to-SNA Conversion Manual
(Part Number T0101-08).
