Configuring Interfaces
Configuring OC-48c SM and MM Interfaces (Catalyst 8540 MSR)
Manual OC-48c Interface Configuration (Catalyst 8540 MSR)
To manually change any of the default configuration values, perform the following steps, beginning in
global configuration mode:
Example
The following example shows how to change the number of active VCI bits to 12:
Switch(config)#
interface atm 9/0/0
Switch(config-if)#
atm max-vci-bits 12
See
Troubleshooting the Interface Configuration, page 18-17
to confirm your interface configuration.
Command
Purpose
Step 1
Switch(config)#
interface atm
card
/
subcard
/
port
Switch(config-if)#
Specifies the ATM interface and enters interface
configuration mode.
Step 2
Switch(config-if)#
atm
uni
[
side
{
network
|
user
}] [
type
{
private
|
public
}] [
version
{
3.0
|
3.1
|
4.0
}]
Modifies the ATM interface side, type, or version.
Step 3
Switch(config-if)#
atm maxvpi-bits
max-vpi-bits
Modifies the maximum VPI bits configuration.
Step 4
Switch(config-if)#
atm maxvci-bits
max-vci-bit
s
Modifies the maximum VCI bits configuration.
Step 5
Switch(config-if)#
sonet
{
stm-16
|
sts-48c
}
Modifies the framing mode.
Step 6
Switch(config-if)#
clock
source
{
free-running
|
loop-timed
network-derived
}
Modifies the clock source.
Step 7
Switch(config-if)#
