Chapter 5. Configuring Ports and Media Modules
This chapter describes:
Ÿ How to enable ports and interfaces
Ÿ
How to set up Virtual Path Channels (VPCs)
Ÿ How to configure reachable addresses
Ÿ How to set up permanent virtual connections (PVCs)
Ÿ
The different ways of connecting switches
Ÿ How to allow or disallow duplicate ATM address registration.
Enabling ATM Ports and Interfaces
Before you can use the devices attached to media module ports, you must enable each port and configure
the type of interface used by the port to receive and transmit ATM data. For example, to enable port 2 of a
module in slot 1 as a UNI port:
à ð
8265ATM
>
set port 1.2 enable uni
á ñ
Note that you can specify multiple ports on the same module within the same command, for example set
port 1.2 3 5 4 7 enable uni would enable ports 2, 3, 4, 5, and 7.
You can set a port to any of the ATM interfaces:
Ÿ User-to-Network (UNI)
Ÿ
Public User-to-Network (public_UNI)
Ÿ Interim Inter-Switch Signalling (IISP)
Ÿ Private Network-to-Network (PNNI)
Ÿ
VOID
Ÿ AUTO.
See “Network Interfaces” on page 4 for more information on ATM network interfaces.
Note: To enable the ports, the module must be connected to the network. See the IBM 8265 Command
Reference Guide for details on the SET MODULE CONNECTED command.
Enabling PNNI Ports on 8260 Modules
The number of PNNI ports that can be enabled on 8260 modules is restricted. The sum total bandwidth of
the ports cannot exceed 212 Mbps. For example
Ÿ If you have a 4-port 100 Mbps module, you can only enable two of the ports (200 Mbps bandwidth).
Ÿ
If you have a 12-port 25 Mbps module, you can enable up to 8 of the ports (200 Mbps).
