OL-4984-01
Caveats
DDTS # CSCdz87944
Error messages indicating “Stuck Ucode” and “MDA_INTERNAL_ERROR” occur when routing
64-byte VLAN tagged frames at line rate. For VLANs, use bridging instead of routing. This issue will
be resolved in a future release.
DDTS # CSCea01675
Packets without an 802.1q VLAN tag are classified as COS 0. This issue will be resolved in a future
release.
DDTS # CSCea11742
When a circuit between two ML POS ports is provisioned OOS, one of the ports might erroneously
report TPTFAIL. This issue exists for both ML100T-12 and ML1000-2 cards. If this occurs, open a
console window to each ML card and configure the POS port to shutdown. This issue will be resolved
in Release 5.0.
DDTS # CSCea20962
No warning is displayed when applying OOS to ML drop ports on the circuit provisioning window. This
issue will be resolved in Release 5.0.
DDTS # CSCea26847
An unexpected card reload can occur when a card is configured to route IP-Multicast traffic and
subsequently sends IP-Multicast frames larger than 1649 bytes. To prevent this, avoid routing
IP-Multicast frames larger than 1649 bytes. This issue is under investigation.
DDTS # CSCin29274
When configuring the same static route over two or more interfaces, use the following command:
ip route a-prefix a-networkmask a.b.c.d
Where a.b.c.d is the address of the outgoing gateway, or, similarly, use the command:
ip route vrf vrf-name
Do not try to configure this type of static route using only the interface instead of the address of the
outgoing gateway in Release 4.0. This issue will be resolved in a future release.
DDTS # CSCin32057
If no BGP session comes up when VRF is configured and all interfaces have VRF enabled ensure that at
least one IP interface (without VRF) is configured and add an IP loopback interface on each node.
