port 0 in the shutdown state, the 3-port GE line card stop passing traffic on all ports.
Conditions: This symptom is observed on a Cisco 12410 that runs Cisco IOS Release 12.0(23)S or
a later release and that is configured with an Engine 2 3-port line card.
Workaround: Reload the 3-port GE line card and leave port 0 in the up/down state.
• CSCin80743
Symptoms: Configurations of interfaces on a legacy interface processor such as an EIP or an FSIP
on a Cisco 7500 series go down after a redundancy-forced switchover.
Conditions: This symptom is observed on a Cisco 7500 series that runs Cisco IOS Release 12.0(28)S
or a later release or Release 12.2(25)S that is configured for SSO or RPR+.
Workaround: Manually reconfigure the interfaces.

• CSCin82862
Symptoms: Multicast traffic is not switched from a multilink interface on a Cisco 7500 series that
is configured for distributed multilink PPP (MLP).
Conditions: This symptom is observed when the router is reloaded or when the multilink interface
flaps.
Workaround: Enter the clear ip mds linecard * command on the Route/Switch Processor (RSP).
• CSCin83445

Conditions: This symptom is observed on a Cisco 7500 series that is configured for distributed MLP
after the router has been reloaded.
Workaround: Enter the shutdown interface configuration command followed by the no shutdown
interface configuration command on the affected multilink interface.
• CSCin84124
Symptoms: After performing a Fast Software Upgrade (FSU), none of the interfaces of the active
RSP come up.
Conditions: This symptom is observed on a Cisco 7500 series after you have performed a FSU to
Cisco IOS Release 12.2(25)S or Cisco IOS Release 12.0(30)S and after an SSO switchover has
occurred.
Workaround: After the FSU, enter the microcode reload command.
