22 ATM Cable Interface Processor (ACIP) Installation and Configuration
Configuring the ACIP
Configure an ACIP Interface
The ACIP interface (or subinterface) uses the configuration defaults shown in Table 1. For
information on how to change the defaults, refer to the “Configuring ATM” chapter of the Wide-Area
Networking Configuration Guide and the “Configuring Interfaces” chapter of the Configuration
Fundamentals Configuration Guide. All ATM and interface commands might not be applicable to
the ACIP interface.
Note If a command is not available, the router displays the message “Command not supported on
this interface.”
To configure the ATM interface on the ACIP, perform the following tasks beginning in global
configuration mode:
Table 1 ACIP Defaults
Parameter Command Default Value
Maximum transmission unit mtu bytes 4470
Exception queue buffers atm exception queue number 32
Receive buffers atm rxbuff number 256
Transmit buffers atm txbuff number 256
Maximum number of virtual
circuits (VCs)
atm maxvc number 2048
ATM raw cell queue size atm rawq-size number 32
ATM VCs per VP atm vc-per-vp number 1024
Source of Transmit Clock atm clock internal Recovered receive clock
Task Command
Step 1 Assign a bridge group.
1
1. For more information on creating bridge groups, refer to the “Configuring Transparent Bridging” chapter
of the Bridging and IBM Network Configuration Guide.
bridge bridge-group protocol {dec | ieee}
Step 2 Specify the interface and enter interface
configuration mode.
interface atm slot/0
2
2. Because the ACIP contains a single interface, the port number is always 0.
Step 3
Assign the bridge group to the interface. bridge-group number
Step 4 Disable the spanning tree on the interface. bridge-group number spanning-disabled
Step 5 Change the shutdown state to up and enable
the interface.
no shutdown
