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 dialing 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-with-BACP calls by having one third dial 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 Chapter 3, “Configuring WAN Access.”
To configure a MAX stack, proceed as follows for each MAX in the stack:
1
Open 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.
