Open Caveats in Release 12.1(11b)E14
• On a Layer 3 EtherChannel, applying an ACL to both the port-channel interface and a member port
prevents the ACL from denying traffic correctly.
Workaround: Remove the ACL from both the port-channel interface and the member port and
reapply it only to the port-channel interface. This problem is resolved in Release 12.1(13)E5.

• If both IOS Server Load Balancing (SLB) and IOS Firewall Load Balancing (FWLB) are configured on
the same router, ICMP packets that need to be firewall load balanced are routed by SLB instead. This
problem is resolved in Release 12.1(12c)E2. (CSCdy18588)
• Packets between fabric-enabled modules can be forwarded from one module to another using either
8-Gigabit Ethernet fabric interface or the 16-Gigabit Ethernet backplane bus. In a system where less
than three fabric-enabled modules are installed, replicated multicast packets are occasionally sent
over the fabric as well as the backplane bus, causing ports to receive twice as many packets as were
generated.
Workaround: Override the default bus mode by entering the fabric switching-mode allow
truncated threshold 1 command. This problem is resolved in Release 12.1(12c)E1. (CSCdw82490)
• To avoid unreliable operation, do not enter the do command in EXEC mode.
Workaround: Turn the switch off and back on again. This problem is resolved in
Release 12.1(12c)E1. (CSCdx02925)
• If you enter the do command under the interface range command, Cisco IOS executes the do
command for each interface in the range. This problem is resolved in Release 12.1(13)E.

• Catalyst 6500 series switches and Cisco 7600 Series Routers support Layer 3 trunks only on the
4-port Gigabit Ethernet WAN module (OSM-4GE-WAN). If you configure a subinterface on a LAN
port, a reload might occur.
Workaround: Do not configure subinterfaces on LAN ports. Catalyst 6500 series switches and
Cisco 7600 Series Routers support Layer 2 trunks and Layer 3 VLAN interfaces, which provide
equivalent capabilities for LAN ports. This problem is resolved in Release 12.1(12c)E1.
