OL-2310-11
Caveats
Resolved Caveats in Release 12.1(11b)E7
• With Supervisor Engine 2, any access to an invalid address in the valid I/O address space can
suspend all operation. This problem is resolved in Release 12.1(11b)E7. (CSCdx81901)
• Switchover to the redundant supervisor engine and MSFC does not occur following a problem on
the MSFC that should cause a switchover. This problem is resolved in Release 12.1(11b)E7.
(CSCdx43539)
• A reload caused by excessive interrupts might fail, with CPU-6-MONITOR-SP-NOT-HEARD
messages displayed. This problem is resolved in Release 12.1(11b)E7. (CSCdy27356)
• With heavy traffic, a SYS-3-NULLIDB traceback message might be displayed and crypto tunnels
might go down. This problem is resolved in Release 12.1(11b)E7. (CSCdw01724)
• Nonmaskable interrupts (NMIs) might cause a Supervisor Engine 1 to reload and the reload might
fail. This problem is resolved in Release 12.1(11b)E7. (CSCdy25902)
• With Release 12.1(11b)E, Release 12.1(11b)E1, Release 12.1(11b)E2, Release 12.1(11b)E3,
Release 12.1(11b)E4, and Release 12.1(12c)E1, the IPSEC prefragmentation feature is enabled by
default with the tunnel interface MTU size set to 1520 bytes. Other releases use 1576 bytes. This
problem is resolved in Release 12.1(11b)E7. (CSCdy03649)
• If you install three or more Content Services Gateway (CSG) modules in the same chassis, a reload
occurs. This problem is resolved in Release 12.1(11b)E7. (CSCdw77156)
• Nonmaskable interrupts (NMIs) might cause a Supervisor Engine 1 to reload, and then the reload
might fail. This problem is resolved in Release 12.1(11b)E7. (CSCdy25902)
Resolved Caveats in Release 12.1(11b)E4
• A multilink PPP bundle might forward traffic intermittently. This problem is resolved in
Release 12.1(11b)E4. (CSCdx48611)
• VLANs in the 1002 to 1005 range are disabled by default in Catalyst software. In the Cisco IOS
images for the Catalyst 6500 series switches and Cisco 7600 Series Routers, the VLANs are in the
forwarding state by default. This default discrepancy might cause a problem in a situation where a
system running Release 12.1(8a)E3 or later on the supervisor engine and the MSFC is connected
through an 802.1 Q tunnel to a system running Catalyst software. If the system running Cisco IOS
software sends BPDUs for reserved VLANs in the 1002 to 1005 range, the system running Catalyst
software drops these BPDUs and increments the rxTotalDrop counter. This problem is resolved in
Release 12.1(11b)E4. (CSCdx28347)
• When the VLAN-bridge protocol is used, VLAN bridge BPDUs are not sent even though the
interface BPDU counters indicate that BPDUs are sent. This problem is resolved in
Release 12.1(11b)E4. (CSCdw80500)
• The following error message displays when an SNMP cardTable MIB walk is performed:
c6k_pwr_get_fru_present(): can't find fru_info for fru type 6, #66
This problem is resolved in Release 12.1(11b)E4. (CSCdx41473)
• When you enter the no ip routing command followed by the ip routing command, the following
error message appears:
A%FIB-4-FIBCBLK
This problem is resolved in Release 12.1(11b)E4. (CSCin09681)
