Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(27)S4
Conditions: This symptom is observed on a Cisco 12000 series that runs Cisco IOS
Release 12.0(26)S or a later release when the resolved ARPs are deleted, for example, when routers
flap, when BGP peers do not respond, or when you enter the clear arp command. Note that the
symptom may also occur on releases earlier than Release 12.0(26)S.
The ingress CoS includes a set command for the matched class: either a police command with a set
command or a simple set command and either a set-mpls command or a set-dscp command.
Possible Workaround: Configure static ARPs.

Symptoms: A Cisco 12000 series line card may rate-limit process-switched packets to the GRP. This
situation causes a ping to be lost when you perform a ping test to the local interface of the router.
Conditions: This symptom is observed when the interface is configured for HDLC, when the
interface has a hard loop, and when the IP address of the interface is the destination of the ping.
Because the interface is in the up/up state (looped) and functional, there should be no packet loss
when you ping the interface at its own IP address.
Workaround: There is no workaround.

Symptoms: When you enter commands in various configuration modes such as address-family,
PVC, service-policy, and so on, an invalid input error message may be returned even though the
command was accepted and entered into the running configuration. The following is an example:
Router(config-router-af)#redistribute connected
address-family ipv4 vrf atmTrk
^
% Invalid input detected at '^' marker.
Conditions: This symptom is observed on a Cisco 12410 that is configured with two Performance
Route Processors (PRP-1) that function in Route Processor Redundancy (RPR) mode and that runs
one of the following images:
- The c12kprp-p-mz image of Cisco IOS Release 12.0(24)S3.
- The c12kprp-p-mz image of Cisco IOS Release 12.0(23)S4.
- The c12kprp-k3p-mz image of Cisco IOS Release 12.0(27)S2
This list is not all-inclusive: the symptom may also occur in Release 12.0(20)S, Release 12.0(20)ST,
and later releases.
The symptom occurs when the do command is interleaved between configuration commands.
Workaround: Verify that the configuration command is properly accepted by entering the show
running-config command.
• CSCef33670
Symptoms: An Engine 4 egress line card that switches traffic may reset when the ingress line card
is shut down.
Conditions: This symptom is observed on a Cisco 12000 series when the ingress line card is an
Engine 3 POS line card and when IP-to-tag traffic is switched.
Workaround: There is no workaround.

Symptoms: A router may crash when you enter the crypto key generate dss key-name command.
