Release Notes for Cisco IOS Release 12.1E on the Catalyst 6500 and Cisco 7600 Supervisor Engine and MSFC
OL-2310-11
Caveats
• With a route in a different VPN routing and forwarding instance (VRF) attached to an interface, the
interface might not be able to receive traffic being sent to an address that is configured on the MSFC.
This problem is resolved in Release 12.1(20)E3. (CSCeb52270)
• A reload might occur if you apply an undefined crypto map to an interface. This problem is resolved
in Release 12.1(20)E3. (CSCin08118)
• Traffic might be dropped if you enter the no ip cef global configuration command. This problem is
resolved in Release 12.1(20)E3. (CSCin40371)
• With MD5 password encryption configured, the software does not correctly verify that all
configured TCP options can be sent in a TCP packet, which can cause this message to be displayed:
%TCP-6-TOOBIG: Tty0, too many bytes of options (44)
This problem is resolved in Release 12.1(20)E3. (CSCeb07106)
• A reload might occur if you establish an SSHv2 session immediately after the “Press RETURN to
get started!” message appears on the console. This problem is resolved in Release 12.1(20)E3.
(CSCin48676)
• In a topology with overlapping networks, EIGRP might incorrectly remove a connected route if you
add a new network command before you remove the old one. This problem is resolved in
Release 12.1(20)E3. (CSCed93804)
• When you configure BGP peergroups, spurious memory access messages are displayed. This
problem is resolved in Release 12.1(20)E3. (CSCec78347)
• With bursty multicast sources on the network, a reload might occur because of a watchdog timeout
if a nondefault holdtime value is received in a Protocol Independent Multicast (PIM) join message.
The holdtime value might be nondefault because it is from a non-Cisco network device or because
the Internet Group Management Protocol (IGMP) query interval has been modified on an interface.
This problem is resolved in Release 12.1(20)E3. (CSCec70366)
• A reload might occur if you remove a network command from an interface where OSPF is
configured and there is OSPF traffic from the interface in the OSPF queue. This problem is resolved
in Release 12.1(20)E3. (CSCec48816)
• When buffer allocation failures occur while free I/O memory is low, Protocol Independent Multicast
(PIM) join messages might not be sent. This problem is resolved in Release 12.1(20)E3.
(CSCec40377)
• A reload because of memory corruption might occur when an IP Security (IPsec) generic routing
encapsulation (GRE) tunnel carries multicast traffic. This problem is resolved in
Release 12.1(20)E3. (CSCec06341)
• Receiving CDP packets with a host name that is 256 or more characters long might cause a memory
leak in the CDP process. This problem is resolved in Release 12.1(20)E3. (CSCin67568)
• Following “cmd failed” messages for ATM configuration commands, an ATM interface might
remain administratively down. This problem is resolved in Release 12.1(20)E3. (CSCin40163)
