Configuring The Interfaces; Port Addresses - Cisco LightStream 1010 Configuration Note

Sample Screen Display for Hot-Swapping Procedure
When you remove and replace CAMs and PAMs, the system provides status messages on the
console screen. The messages are for information only. In the following sample display, you can
follow the events logged by the system when a PAM was removed from slot 3/0. When the PAM is
reinserted, the system marks the module as ready again.
Switch#
%OIR-6-REMCARD: Card removed from slot 3/0, interfaces disabled
%LINK-5-CHANGED: Interface 155UTP 3/0, changed state to administratively down
%LINK-5-CHANGED: Interface 155UTP 3/0, changed state to administratively down
Switch#
%OIR-6-INSCARD: Card inserted in slot 3/0, interfaces administratively shut down
%LINK-5-CHANGED: Interface 155UTP 3/0, changed state to up
%LINK-5-CHANGED: Interface 155UTP 3/0, changed state to up
Port Adapter Module Configurations
The PAMs support different media and interface types. The configuration commands used with these
different PAMs vary according to PAM type. For complete PAM configuration information, refer to
the publications LightStream 1010 ATM Switch Configuration Guide and LightStream 1010 ATM
Switch Command Reference.
Configuring the Interfaces
After you install the module, use the following information to configure the module and the
individual interfaces on the 622 MM/SM modules. In the LightStream 1010 ATM Switch User Guide
the section "LightStream 1010 ATM Switch Hardware" contains an overview of the port and module
numbering scheme used to configure the 622 PAMs. The section "Configuring the LightStream 1010
ATM Switch" describes how to configure the ports on the FDDI or CDDI module. The section
"Confirming the Installation" describes the procedures you should use to confirm that the 622 PAMs
are configured correctly.

Port Addresses

Each interface (or port) in the switch is designated by several different types of addresses. The
physical interface address is the actual physical location (card/subcard/port) of the interface
connector within the chassis. The system software uses the physical addresses to control activity
within the switch and to display status information. These physical card/subcard/port addresses are
not used by other devices in the network; they are specific to the individual switch and its internal
components and software.
The following sections describe how the LightStream 1010 switch assigns and controls both the
physical (card/subcard/port) and Media Access Control (MAC)-layer addresses for interfaces within
the chassis.
Port IDs
In the LightStream 1010 switch, the port ID specify the actual physical location of each PAM port
on the front of the switch. (See Figure 13.) The address is composed of a three-part number in the
format card/subcard/port. The first number identifies the slot in which the module is installed.
Module slots are numbered 0 to 4 from top to bottom. The second number identifies the subcard or
PAM number. The PAMs are numbered 0 and 1 with 0 being the left PAM facing the front of the
switch. The third number identifies the physical port number on the module. The port numbers
