Caveats
Resolved Caveats—Cisco IOS Release 12.0(31)S
• CSCeh43864
Symptoms: The line protocol on the POS interface of a PA-POS-OC3 port adapter flaps
continuously.
Conditions: This symptom is observed on a Cisco 7500 series that runs Cisco IOS interim
Release 12.3(14.10) but may also occur in other releases.
Workaround: There is no workaround.
• CSCin79468
Symptoms: An ATM subinterface enters the up/up state regardless of whether or not a PVC is down.
Conditions: This symptom is observed on a Cisco 7500 series that is configured with a PA-A3 port
adapter when the router boots up without a connecting cable. This situation causes a PVC to remain
down. The PVC remains down even after you connect the cable and the ATM subinterface enters the
up/up state.
Workaround: Enter the shutdown interface configuration command followed by the no shutdown
interface configuration command on the ATM subinterface with the PVC that is down.
• CSCin84694
Symptoms: On a Cisco 7x00 series that runs Cisco IOS Release 12.3 and that is equipped with an
ATM PA-A3 port adapter, the SAR chip of the port adapter may crash or the interface may become
stuck.
Conditions: This symptom is observed when there is a high-traffic load on the ATM PA-A3 port
adapter and when many VCs are created, deleted, and modified continuously. The symptom may
also occur in other releases.
Workaround: There is no workaround.
• CSCin86455
Symptoms: Auto-provisioning may be disabled on a Cisco 7200 series that is configured with a
PA-A3 port adapter.
Conditions: This symptom is observed when a VC class that is configured for create on-demand is
attached to the main ATM interface and then the create on-demand configuration is removed and
re-applied to the VC class.
Workaround: Enter the shutdown interface configuration command followed by the no shutdown
interface configuration command on the ATM interface of the PA-A3 port adapter.
• CSCin86673
Symptoms: A VC may become stuck and stop transmitting traffic.
Conditions: This symptom is observed on a Cisco 7200 series that is configured with a PA-A3 or
PA-A6 port adapter when there is a high traffic load and when the QoS class of the VC is changed.
Workaround: Enter the shutdown interface configuration command followed by the no shutdown
interface configuration command on the interface that contains the affected VC.
IP Routing Protocols
• CSCdr31946
Symptoms: A Cisco router that is runs Enhanced Interior Gateway Routing Protocol (EIGRP) with
the stub feature enabled may have a route that is active and not waiting for replies.
Conditions: This symptom is observed only in networks where all of the EIGRP neighbors are
declared as stub.
