Release Notes for Cisco IOS Release 12.1E on the Catalyst 6500 and Cisco 7600 Supervisor Engine and MSFC
OL-2310-11
Caveats
A redundant supervisor engine might not reload if you enter the reload command on the redundant
supervisor engine's console or physically remove and reinsert the redundant supervisor engine. This
problem is resolved in Release 12.1(19)E. (CSCea66858)
When not configured with a redundant power supply, continuous reloads might happen if the output
from the single power supply is momentarily unstable, which causes this message to be displayed:
"%C6KPWR-2-INSUFFICIENTPOWER: Powering down all linecards as there is not enough power
to operate all critical cards"
This problem is resolved in Release 12.1(19)E. (CSCea82777)

Open FlexWAN Caveats in Release 12.1(19)E1a
In a system installed with a FlexWAN and a PA-A3 ATM port adapter, the ATM interface may stay
down after you enter a shutdown command followed immediately by a no shutdown command.
Workaround: After you enter the shutdown command on the interface, wait for 1 minute before
entering the no shutdown command. This problem is resolved in Release 12.1(20)E. (CSCdy23751,
CSCdw65799)
Resolved FlexWAN Caveats in Release 12.1(19)E1a
Spurious memory accesses in cwpa_1483_bridge_vlan_pvc_egress_classify occur following a
reload. This problem is resolved in Release 12.1(19)E1a. (CSCin39391)
With modular QoS CLI (MQC) fragmentation and shaping configured on a FlexWAN Frame Relay
interface, the FlexWAN module might pause indefinitely, produce large numbers of spurious
memory accesses, or reload; and produce messages reporting that the FlexWAN interfaces are not
sending packets and that the output of the interfaces is stuck. This problem is resolved in
Release 12.1(19)E1a. (CSCeb22972, CSCeb00104)
Resolved FlexWAN Caveats in Release 12.1(19)E1
With a redundant Supervisor Engine 2, crypto images do not recognize FlexWAN modules at bootup
when RPR is configured. This problem is resolved in Release 12.1(19)E1. (CSCeb47607)
With dial-up networking (DUN) configured, the IP Control Protocol (IPCP) times out on a link
control protocol (LCP) negotiation. This problem is resolved in Release 12.1(19)E1. (CSCea51540)
The counters in the show interfaces command for FlexWAN interfaces are not accurate. This
problem is resolved in Release 12.1(19)E1. (CSCea06360)
A reload might occur when you configure an ATM bundle. This problem is resolved in
Release 12.1(19)E1. (CSCeb03367)
