Release Notes for Cisco IOS Release 12.1E on the Catalyst 6500 and Cisco 7600 Supervisor Engine and MSFC
OL-2310-11
Caveats
–
While all corresponding Layer 2 ports remain inactive, the Layer 3 VLAN interface is
administratively enabled (no shutdown).
This problem is resolved in Release 12.1(26)E5. (CSCsc08947)
• The SNMP ifAdminStatus state for the ATM layer or the ATM Adaptation Layer 5 (AAL5) of an
ATM interface or subinterface might go down. This situation can occur without entering a shutdown
command, and prevents SNMP from monitoring the proper status of the ATM interfaces. This
problem is resolved in Release 12.1(26)E5. (CSCsb12329)
• If traffic loss occurs when there is a high volume of broadcast traffic, the input broadcast counter
increments and the input counter does not increment. Because the value of the SNMP
ifHCInUCastPkts MIB object is the difference between the input counter and the input broadcast
counter, the value of ifHCInUCastPkts might become negative. This problem is resolved in
Release 12.1(26)E5. (CSCsc62574)
• The ports that are associated with a static MAC entry disappear from the show mac-address-table
command static output, and the connectivity is disrupted. This problem occurs in either of the
following ways:
–
With a static MAC address configured with the disable-snooping keyword, disable, and enable
IGMP snooping.
–
With a static MAC address configured with the disable-snooping keyword and IGMP snooping
enabled, delete, and reconfigure the static MAC address.
This problem is resolved in Release 12.1(26)E5. (CSCsc36963)
• Packets that are going to be Layer 3 switched and are destined for a Hot Standby Router Protocol
(HSRP) virtual MAC address (VMAC), are forwarded before the HSRP state becomes ACTIVE on
the destination interface. This problem occurs when you enter the shutdown and no shutdown
interface configuration commands on the destination interface. This problem is resolved in
Release 12.1(26)E5. (CSCsb78050)
Resolved General Caveats in Release 12.1(26)E4
• A system configured with a summary address, which is also an OSPF not-so-stubby area (NSSA)
area border router (ABR), might incorrectly age out and flush the summary address. This occurs
when NSSA external type 1 or type 2 routes are present. This problem is resolved in
Release 12.1(26)E4. (CSCsb28595)
• SLB real servers move to FAILED TESTING or READY_TO_TEST when a PROBE_ABDICATE
event occurs. After this event occurs, the real servers will never become operational with per-packet
virtual servers and Internet Control Message Protocol (ICMP) probes. This problem is resolved in
Release 12.1(26)E4. (CSCsb14185)
• If an intermittent multicast source is inactive for 3.5 minutes, (S,G) entries in the MSDP cache might
become inconsistent with a neighbor’s cache which can cause multicast packet loss. This problem
is resolved in Release 12.1(26)E4. (CSCsb23433)
• When a server farm is configured with two probes, and a real server is taken out of service and then
brought back into service, one of the two probes configured for the server farm does not display the
real server when you use the show ip slb probe command. This problem is resolved in
Release 12.1(26)E4. (CSCsa73607)
• WCCP does not redirect traffic to cache engines from suppliers other than Cisco Systems if you do
not configure a redirection port on the cache engine. This problem is resolved in
Release 12.1(26)E4. (CSCei38603)
• The snmp-server tftp-server-list command fails to apply an access list for SNMP traffic. This
problem is resolved in Release 12.1(26)E4. (CSCdu32036)
