Caveats
Resolved Caveats—Cisco IOS Release 12.0(31)S5
Conditions: This symptom has been observed in an E4+ LC card when the line card does not find
enough free sequential entries in TCAM at its current location because of ACL expansion and needs
to relocate ACL to a different location within the TCAM.
Workaround: Perform a workaround similar to the example which follows:
An example configuration of access-list 102 and 103 applied on GigabitEthernet interface at 9/0/1.
1. Remove all of the ACL applied to that line card interfaces globally.
config terminal
no access-list number [number = 102, 103]
2. Remove all of the ACL configuration from the line card interfaces.
config terminal
interface GigabitEthernet 9/0/1
no ip access-group number out [number = 102, 103]
3. On line card confirm that the ACLs have been removed.

4. Recreate the ACL globally, which are the ACL deleted in Step 1.
5. Re-apply the ACL configuration to the LC interfaces, the one’s deleted in Step 2.
6. On the line card, confirm that the ACLs have been recreated properly.

Symptoms: When you reload a channelized T3 SPA that is installed in a PE router, all interfaces on
a directly-connected channelized T3 SPA that is installed in a CE router remain in the down state,
and the following error message is generated:
%SPA_CHOC_DSX-3-SPA_CMD_SEND_ERR: Failed to send ipc_send_rpc_blocked command to
SPA
Conditions: This symptom is observed in a VPN topology on a Cisco 12000 series that runs
Cisco IOS Release 12.0(32)S1, that functions as a PE router, and that is connected to another
Cisco 12000 series that functions as a CE router. The channelized T3 SPA in the PE router is
installed in a SIP-601; the channelized T3 SPA in the CE router is installed in a SIP-400.
Workaround: Reload the channelized T3 SPA in the CE router.

Symptoms: When the controller of multichannel T3 port adaptor SPA-4XCT3 goes down for a short
duration and an alarm occurs, the port adapter does not report the type of alarm.
Conditions: This symptom has been observed on Cisco 7600 series and Cisco 12000 series routers
that are configured with a SPA-4XCT3. The port adapter should provide a history table of recent
alarm conditions along with a corresponding time stamp to allow for proper troubleshooting.
Workaround: There is no workaround.

Symptoms: ATM PVCs configured with OAM on the FlexWAN module/PA-A3-OC3 might go
down. This occurs because OAM cells are not being received correctly on the ATM PVCs. The ATM
interface remains up/up, but the subinterfaces with PVCs configured go down/down.
Subinterfaces with PVCs without OAM configured remain up/up, but the traffic does not pass.
