Release Notes for Cisco IOS Release 12.0 S
78-7130-11 Rev. B0
Caveats
• CSCdr57725
On a Cisco 12000 series Gigabit Switch Router (GSR), the performance card might double-count
software-switched input packets. The packet count for hardware-switched packets is not affected.
Workaround: Do not configure Gigabit Ethernet static routes to another adjacent Gigabit Ethernet
interface.
• CSCdr64798
In certain configurations, the ATM permanent virtual connection (PVC) service policy might not
function properly after the router has reloaded. In this situation, there are no feature counters in the
show policy interface command output.
Workaround: Remove and then reattach the service policy after the router is reloaded.
• CSCdr65982
If the fair-queue interface configuration command is entered more than once within the same class
in which weighted fair queueing is already enabled on that same interface, the router might reload.
There is no workaround.
• CSCdr73378
When the packet switch ASIC (PSA) access list (ACL) feature is enabled by entering the access-list
hardware {psa} global configuration command and the feature was previously disabled with the
no access-list hardware {psa} command, output ACLs that should be processed by the PSA might
be processed on the line card CPU.
Workaround: Avoid toggling the state of the access-list hardware {psa} command. This situation
will not occur if the command is in the startup configuration and is not toggled.
• CSCdr73473
Removing and attaching a service policy under a traffic load might cause spurious memory access
errors and high CPU utilization on the Versatile Interface Processor (VIP). This spurious access
occurs at hqf_get_policymap().
Workaround: Stop background traffic before making configuration changes.
• CSCdr74025
The spatial reuse protocol (SRP) line card on a Cisco 12000 series Gigabit Switch Router (GSR)
that is running Cisco IOS Release 12.0(11.5)S might reload unexpectedly upon start-up. There is
no workaround.
