Release Notes for Cisco IOS Release 12.1E on the Catalyst 6500 and Cisco 7600 Supervisor Engine and MSFC
OL-2310-11
Limitations and Restrictions
• The interface range command is not supported by the HTTP user interface. The command will
execute on only the first interface in the specified range. Do not use the interface range command
with the HTTP interface. (CSCdm54471)
• Supervisor Engine 2 and Supervisor Engine 1 typically are able to learn at least 32 K MAC
addresses.
• When you boot Release 12.1(13)E1 dsv images, the following messages are displayed:
00:01:15: %PPP-4-NOREGISTER: NCP not registered, protocol = 0
00:01:15: %PPP-4-NOREGISTER: NCP not registered, protocol = 0
00:01:15: %PPP-4-NOREGISTER: NCP not registered, protocol = 0
00:01:15: %PPP-4-NOREGISTER: NCP not registered, protocol = 0
00:01:15: %PPP-4-NOREGISTER: NCP not registered, protocol = 0
00:01:15: %PPP-4-NOREGISTER: NCP not registered, protocol = 0
These messages are informational only. (CSCdy38295)
• With Release 12.1(11b)EX and earlier releases, a redundant Supervisor Engine 1 might fail to boot
following a reload.
Workaround: Enter the no power enable module redundant_slot and power enable module
redundant_slot commands. (CSCec07946)
• Fast-switched IP multicast traffic is dropped when it matches a permit access list entry configured
with the log keyword. Fast switching of IP multicast packets is enabled by default. (CSCds28581)
• When using the UplinkFast feature, the system does not send out the dummy multicast packets used
to notify upstream users of forwarding-path changes. The system uses normal Layer 2 aging to
delete invalid entries. (CSCdm65881)
• A MAC address that moves from a secure port to a nonsecure port and back to a secure port might
cause high Supervisor Engine CPU utilization.
Workaround: Clear the MAC address entry from the MAC address table. Enable port security on
all ports where MAC address moves are common. (CSCin56672)
• If the MSFC address falls within the range of a PBR ACL, traffic addressed to the MSFC is policy
routed in hardware instead of being forwarded to the MSFC. To prevent policy routing of traffic
addressed to the MSFC, configure PBR ACLs to deny traffic addressed to the MSFC. (CSCse86399)
FlexWAN Limitations and Restrictions
• On FlexWAN ports configured for EoMPLS, the counters displayed by the show mpls command for
parallel links between LERs do not update. (CSCdw04208, CSCdu87648)
• On FlexWAN ports, an EoMPLS virtual circuit stays up when the VLAN interface is down.
(CSCdv69982)
• Ethernet over Multiprotocol Label Switching (EoMPLS) per-VLAN traffic shaping does not work
with a FlexWAN egress port. (CSCdx10583)
• On FlexWAN ports, an EoMPLS virtual circuit stays up when the VLAN interface is down.
(CSCdv69982)
• To use the interfaces on the FlexWAN module, you must enable IP routing on the MSFC.
(CSCdp34896)
• Support for MPLS and EoMPLS features on FlexWAN requires a Supervisor Engine 2 and MSFC 2.
