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
• These modules do not support Inter-Switch Link (ISL) VLAN trunking:
– WS-X6502-10GE
– WS-X6548-GE-TX
– WS-X6148-GE-TX
• The link state messages (“LINK-3-UPDOWN” and “LINEPROTO-5-UPDOWN”) are disabled by
default. With Release 12.1(19)E1a and later releases, enter the logging event link status command
on each interface where you want the messages enabled.
• In Release 12.1(19)E and later releases, you cannot disable IP routing. (CSCdu05871)
• IPsec in software on the MSFC is supported only for administrative connections to Catalyst 6500
series switches and Cisco 7600 series routers.
• SPAN and RSPAN destination ports and VACL capture ports can receive VACL-redirected traffic.
(CSCea57673)
• If you have a network device in your network with MAC address reduction enabled, you should also
enable MAC address reduction on all other Layer-2 connected network devices to avoid undesirable
root bridge election and spanning tree topology issues.
When MAC address reduction is enabled, the root bridge priority becomes a multiple of 4096 plus
the VLAN ID. With MAC address reduction enabled, a switch bridge ID (used by the spanning-tree
algorithm to determine the identity of the root bridge, the lowest being preferred) can only be
specified as a multiple of 4096. Only the following values are possible: 0, 4096, 8192, 12288, 16384,
20480, 24576, 28672, 32768, 36864, 40960, 45056, 49152, 53248, 57344, and 61440.
If another bridge in the same spanning-tree domain does not run the MAC address reduction feature,
it could win root bridge ownership because of the finer granularity in the selection of its bridge ID.
• Enter the copy running-config startup-config command and the redundancy reload peer
command to synchronize SNMP ifIndexes when RPR+ redundancy and SNMP ifIndex persistence
are configured when all modules are online after any system boot or when you insert a module while
the system is running. (CSCdy16763)
• RPR+ redundancy automatic startup configuration synchronization supports only the
nvram:startup-config file. With RPR+ redundancy configured, if you enter a boot config command
that does not specify nvram:startup-config as the startup configuration file, you must manually copy
the startup configuration file to the redundant supervisor engine’s device specified in the boot config
command. (CSCdx25320)
• RPR+ redundancy does not support configuration entered in VLAN database mode. Use global
configuration mode with RPR+ redundancy.
• The following Supervisor Engine 1 software images exceed the 16 MB Supervisor Engine 1
bootflash size:
