Cisco Cisco ONS 15454 SONET Multiservice Provisioning Platform (MSPP) Guía Para Resolver Problemas
Provisioning/Network tab in the Cisco Transport Controller (CTC).
Problem
The Cisco ONS 15454 uses both IP and MAC addresses for circuit routing. When an Invalid MAC Address
alarm exists on a node, an incomplete circuit appears in CTC in the circuit status column. The circuit still
works and carries traffic without any problem, but the CTC cannot logically display the end−to−end
information for that circuit.

information for that circuit.
Cause
Here are the possible causes of an invalid MAC address:
The TCC cards read the chassis MAC address value from the AIP card at boot−up. If there is a read
error, the default MAC address (00−10−cf−ff−ff−ff) is used.

•
The two TCC cards in the Cisco ONS 15454 read the MAC address independently, so a read error can
cause each card to read a different value for the address.

Solution
Complete these steps in order to resolve this problem:
Resolve any outstanding alarms raised against the active or standby TCC+/TCC2.
1.
Visually inspect the LCD display on the fan tray.
If the LCD is blank or the text is garbled, proceed to step 7.
2.
At the earliest maintenance window, perform a software reset on the standby TCC+/TCC2.
Right−click the standby TCC+ when logged into CTC, and select Reset Card. You receive a prompt
to indicate whether you are sure. Choose Yes. As the card resets, a loading (Ldg) indication appears
on the card in CTC.

Note: The reset takes approximately five minutes. Do not perform any other steps until the reset is
complete.

If this card fails to boot up in Stby and continuously reloads, the AIP is probably defective. The Stby
TCC+/TCC2 attempts to read the erasable programmable read−only memory (EEPROM) on the AIP,
and continues to reload until it is successful. Proceed to step 7.

3.
Sideswitch the TCC+/TCC2s. To do so, follow the procedure in the Reset Active TCC+/TCC2 Card
and Activate Standby Card section in chapter 2 of the Cisco ONS 15454 Troubleshooting Guide,

Check whether the INVMACADR alarm is still present.
When you reset the active TCC+/TCC2, the standby TCC+/TCC2 becomes active. The standby
TCC+/TCC2 keeps a copy of the chassis MAC address. If the stored MAC address is valid, the alarm
must clear.

Sideswitch the TCC+/TCC2s once again to make the original TCC active. To do so, follow the
