Caveats
Resolved OSM Caveats in Release 12.1(8a)E5
When the fiber-optic cable carrying traffic from the add-drop multiplexer (ADM) is removed from
a packet-over-SONET (POS) interface, the automatic protection switchover (APS) does not occur.
This problem is resolved in Release 12.1(8a)E5. (CSCdv53401)
If an Optical Services Modules (OSM) has three or more Gigabit Interface Converters (GBICs) with
no link, CPU utilization on the OSM increases and some functions of the OSM, such as a module
image upgrade by the MSFC2, take much longer than normal or fail to complete. This problem is
resolved in Release 12.1(8a)E5. (CSCdu83474)
Resolved OSM Caveats in Release 12.1(8a)E4
OSMs might go down after an MSFC reload. This problem is resolved in Release 12.1(8a)E4.

Open Caveats in Release 12.1(7a)E6
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)
The crypto map interface command is disabled to prevent a reload. This problem is resolved in
Release 12.1(8a)E. (CSCdt56832)
Jumbo frame support is incompatible with the IS-IS routing protocol. Leave the MTU size at the
default value on any interface where IS-IS provides routing. This problem is resolved in
Release 12.1(11b)E. (CSCdu09773)
With very heavy traffic, online insertion or removal of a WS-X6408-GBIC or WS-X6408A-GBIC
8-port Gigabit Ethernet switching module might cause the supervisor engine to reload. This problem
is resolved in Release 12.1(8a)E. (CSCdt91705)
It is safe to ignore c6k_stack_mib_module_added:error 3 from idprom_image_find() error messages
during boot up. This problem is resolved in Release 12.1(8a)E. (CSCdt87637)
When you configure VINES routing, all MSFC2s autoconfigure the same vines node number. The
workaround is to enter the vines routing recompute command. This problem is resolved in
Release 12.1(8a)E2. (CSCdu03802)
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)
