Chapter 18 Configuring Interfaces
Configuring 622-Mbps SM and MM Interfaces
Manual 622-Mbps Interface Configuration
To manually change any of the default configuration values, perform the following steps, beginning in
global configuration mode:
Examples
The following example shows how to change the default ATM interface type to private using the
atm uni type private command:
Switch# configure terminal
Switch(config)# interface atm 0/0/0
Switch(config-if)# atm uni type private
The following example shows how to change the clock source using the clock source network-derived
command:
Switch# configure terminal
Switch(config)# interface atm 0/0/0
Switch(config-if)# clock source network-derived
See Troubleshooting the Interface Configuration, page 18-17 to confirm your interface configuration.
Command Purpose
Step 1
Switch(config)# interface atm card/subcard/port
1
Switch(config-if)#
1. The subcard for the full-width 622-Mbps interface module is always zero.
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-bits Modifies the maximum VCI bits configuration.
Step 5
Switch(config-if)# sonet {stm-4c | sts-12c}
or
Switch(config-if)# framing {stm-4c | sts-12c}
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)# sonet overhead {c2 bytes |
j0 {bytes | msg line} | j1 {16byte {exp-msg line |
msg line} | 64byte {exp-msg line | msg line}} |
s1s0 bits}
Modifies the path trace message.
Step 8
Switch(config-if)# sonet threshold {sd-ber |
sf-ber | b1-tca | b2-tca | b3-tca} ber
Modifies the bit error rate threshold value from
3 (10e-3) to 9 (10e-9).
Step 9
Switch(config-if)# sonet report {slos | slof | lais |
lrdi | pais | prdi | plop | sd-ber | sf-ber | b1-tca |
b2-tca | b3-tca}
Enables reporting of selected alarms.
