Chapter 3
Managing the Operational Link Map
The operational link map determines the connections between the links on a Network 9000
module and either the midplane Ethernet segments or an external LAN or WAN. This
chapter explains the default and optional connections on Type 2 modules and how to change
them. These are the sections in this chapter:
•
Changing Link Maps

Description of the DEFINE [SERVER] CHASSIS SLOT command
You can change the link map only on the processor module where you are logged on. To
change the link map of any other Type 2 processor module in the chassis, log on to the
command interface of that processor module. Use the CHASSIS CONSOLE SLOT
command to log on through the LMB. You can also use the REMOTE CONSOLE or
TELNET CONSOLE command. Chapter 2 describes these commands in detail.
Changing Link Maps
Each processor module has a default link map which becomes operational when you
initialize the processor module. You can change this link map with a chassis
management command or through SNMP.
The following command changes a connection in the link map:
DEFINE [SERVER] CHASSIS SLOT [LINK] [identifier] selection
The LINK keyword is optional. The identifier variable specifies the type of link: either
Ethernet or Ethernet Repeater. The selection variable specifies either a midplane Ethernet
segment or an external LAN. See the command description later in this chapter for
complete information about the keywords and variables in this command. When you
change a link connection with this command, the change takes effect immediately, and
remains in effect until you change it again.
You can view the link map of any processor module with the SHOW/MONITOR CHASSIS
SLOT STATUS command, described in detail in Chapter 5. The following sections show
the default link map for a concentrator, a terminal server, a LAN bridge/router, and a
WAN bridge/router, and the optional connections that are available for each link.
