(CSCdr17019)

• The ifInNUcastPkts MIB object (1.3.6.1.2.1.2.2.1.12) does not increment correctly. This problem is

Open Caveats in Release 12.1(2)E2

• You cannot configure the MTU size on VLAN interfaces. For Supervisor Engine 2, this problem is

resolved in Release 12.1(8a)E. For Supervisor Engine 1, this problem is resolved in

Release 12.1(7)E. (CSCdr62024)

• The copy running-config startup-config command does not save the boot system flash command

in the startup configuration file. Use the write memory command instead. This problem is resolved

in Release 12.1(6)E. (CSCds43994)

• The ciscoFlashDeviceInitTime CISCO-FLASH-MIB object does not return the correct device

initialization (insertion or removal) timestamp for the flash devices on a redundant supervisor

engine. Users of applications that depend on ciscoFlashDeviceInitTime should take care not to

remove a redundant supervisor or a PCMCIA card from slave-slot0:when the applications are

performing flash file operations. This problem is resolved in Release 12.1(11b)E. (CSCdp98597)

• Downloading images to an Intel Value series 200 flash card in the PCMCIA slot may in rare

situations fail to write a valid image. Downloading during periods of low system activity reduces the

likelihood of this failure. This problem is resolved in Release 12.1(6)E (see the related

Release 12.0(7)XE1 resolved CSCdm52806 caveat). (CSCdm52806)

• A traceback message displays when you exit the switch console. This message is harmless and can

be safely ignored. This problem is resolved in Release 12.1(8a)E. (CSCdp35517)

• In a redundant configuration, there is no command that identifies the active supervisor engine. As a

workaround, enter show idprom sup 1 and show idprom sup 2 commands. The command that fails

identifies the redundant supervisor engine. This problem is resolved in Release 12.1(3a)E3 with the

show module command. (CSCdr29969)
