OL-2310-11
Caveats
Resolved Caveats in Release 12.1(1)E2
• After setting the config-register to 0x02, entering a sync command, and reloading, the
config-register is 0x0. This problem is resolved in Release 12.1(1)E2. (CSCdr25147)
• The SLB stateless redundancy inservice standby name command results in an endless loop. This
problem is resolved in Release 12.1(1)E2. (CSCdr24308)
• If the egress interface list for a multicast flow is empty (because there are no interested hosts or
multicast routers), the multicast flow may not get Layer 3 switched. A high volume of traffic to the
empty egress interface list can cause high MSFC CPU utilization.
Workaround: Enter the show ip mroute command to identify flows that are not Layer 3 switched
and then enter the clear ip mroute command for the identified multicast flows. This problem is
resolved in Release 12.1(1)E2. (CSCdr22769)
• Following a reload, SLB does not load-balance traffic until the shutdown and then the no shutdown
commands are entered for the SLB interfaces. This problem is resolved in Release 12.1(1)E2.
(CSCdp95180)
• With CEF enabled on an MSFC that is serving as the active HSRP router, pinging across the MSFC
has only a 50-percent success rate. This problem is resolved in Release 12.1(1)E2. (CSCdm68596)
• On an MSFC with CEF enabled, IP traffic through tunnel interfaces experiences packet loss. This
problem is resolved in Release 12.1(1)E2. (CSCdr16213)
• The MLS entry for an end station must be manually cleared if, before the MLS entry ages out, the
end station is replaced by another that uses the same IP address but that has a different MAC address.
This problem is resolved in Release 12.1(1)E2. (CSCdp64112)
• WCCP does not work with CEF enabled. This problem is resolved in Release 12.1(1)E2.
(CSCdr10156)
• On the WS-X6408-GBIC 8-port Gigabit Ethernet switching module, when QoS is enabled:
–
It is safe to ignore “port_rx_enable errors” messages displayed following the no shutdown
command or reload.
–
QoS WRR configuration commands for WS-X6408-GBIC ports are not saved in NVRAM. You
must manually reenter any nondefault QoS WRR configuration commands for
WS-X6408-GBIC ports after reboot.
–
Gigabit EtherChannels can contain ports on one or more WS-X6408-GBIC switching modules.
Gigabit EtherChannels that contain ports on a WS-X6408-GBIC switching module and on a
WS-X6K-SUP1-2GE supervisor engine fail.
This problem is resolved in Release 12.1(1)E2. (CSCdp81930)
Resolved Caveats in Release 12.1(1)E
• Power cycling the redundant supervisor engine is not supported. This problem is resolved in
Release 12.1(1)E. (CSCdp55523)
• An error-caused reload does not write a crashinfo file for the MSFC. This problem is resolved in
Release 12.1(1)E. (CSCdp94153)
• In a switch with redundant supervisor engines, the slot0 device and the MSFC bootflash device on
the redundant supervisor engine are accessible. The bootflash device on the redundant supervisor
engine is not accessible. Because converting from Catalyst software to Cisco IOS software requires
formatting the supervisor engine bootflash device, do not convert switches while redundant
