Open Caveats in Release 12.1(6)E8
• Secure shell (SSH) support does not work with MSFC2. This problem is resolved in
Release 12.1(8a)E. (CSCdt56832)
• 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)
• 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, CSCdr54103)
• The MSFC2 does not support the MultiNode Load Balancing (MNLB) forwarding agent of the
MNLB feature set for LocalDirector. This problem is resolved in Release 12.1(8a)E. (CSCdr65433)
• The ciscoFlashDeviceInitTime CISCO-FLASH-MIB object does not return the correct device
initialization (insertion or removal) time stamp 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 engine 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.

• 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)
