4-62 MAX 6000/3000 Network Configuration Guide
Configuring Individual WAN Connections
Configuring MP, MP+ and BACP connections
MAX units in the stack. As in “MP without BACP” on page 4-47 calls di aling 555-1215 first
completely fill the channels of MAX #1, then continue to MAX #2, and so on.
Both MP+ and MP callers dial the global hunt group number to connect to the stack.
MP+ and MP-with-BACP callers do not have to dial the global hunt group numbers to connect.
Only the MP-without-BACP callers need to dial the global hunt group. You can achieve an
even distribution of MP+ and MP-w ith-BACP calls by having one third d ial 555-1212, one
third dial 555-1213, and one third dial 555-1214. You can leave the Ch N # parameters at their
default setting (null) in this situation.
The stacking parameters
This section provides some background information about the stack parameters that appear in
Ethernet > Mod Config > Stack Options:
For complete details about each parameter, see the MAX Reference.
Configuring a MAX stack
This section shows how to configure a stack of two MAX units. It does not show the details of
configuring hunt groups, which is an important factor for stacked MP connection. For details
about hunt groups, see Chapter3, “Configuring WAN Access.”
To configure a MAX stack, proceed as follows for each MAX in the stack:
1Open the Ethernet > Mod Config menu and select Stack Options. For example:
Ethernet
Mod Config
RADIUS Server
Log
ATMP
Modem Ringback=Yes
AppleTalk
SNTP Server
Parameter Description
Stacking Enabled Enables the MAX unit to communicate with other members of the
same stack. A unit can belong to only one stack. All members of the
stack use the same stack name and UDP port.
Stack Name Specifies a stack name. Add a MAX unit to an existing stack by
specifying that name. Create a new stack by specifying a new stack
name.
UDP Port Stacked MAX units communicate with other members of the stack by
using a directed-broadcast Ethernet packet on the specified UDP port.
Because directed-broadcast packets are unlikely to cross a router, and
because of the high traffic demands created by a multilink call that
spans MAX units, all members of a stack must reside on the same
physical LAN.
Multicast Addr A valid, class D address, which enables IP multicasting in a
stacked-MAX environment.
