Resolved Caveats for Release 4.1.3
Line Cards
DDTS # CSCea16455, CSCea37089, CSCea37185
Malformed SNMP packets can potentially cause the XTC, TCC/TCC+/TCC2 and TCCi/TCC2 control
cards to reset. Repeated transmission of these malformed packets could cause both the control cards to
reset at the same time. This issue is resolved in Release 4.6, and maintenance Releases 4.0.1, 4.0.3, and
4.1.3.
DDTS # CSCed05846
In Releases 4.0, 4.0.1, and 4.1 the standby TCC+, TCC2, or XTC card might reset automatically. This
can occur at any time, but only rarely. This issue is resolved in Release 4.6, and maintenance Releases
4.1.1 and 4.1.3.
DDTS # CSCeb34326
Rarely, an E1-42 card can go into continual autoreset. This can occur after the E1-42 card is inserted, or
following a node power cycle. Hard reset the E1-42 by removing and re-inserting it into the chassis to
stop this cycle. This issue is resolved in a Release 4.1.3.
DDTS # CSCec13638
Rarely, a greater than 2 second traffic hit can occur when the active XC is pulled, then you switch the IO
from active (Working) to standby (protect). This issue is resolved in Release 4.1.3.
DDTS # CSCeb42187
Occasionally, if you remove the active working E1-42 card, the card takes a greater than 60 ms hit. This
issue is resolved in Release 4.1.3.
DDTS # CSCeb41057
On an E1-42, the LOSS-L parameter appears as random values. For example, sometimes it appears as
-269,488,145. This makes the count unavailable from the card. This issue is resolved in Releases 4.6 and
4.1.3.
DDTS # CSCeb49051
If you configure 1:N or 1:1 protection for DS1, DS3, E1, or E3, then lock the XC and soft reset the active
XC, after the XC finishes resetting, the protection for the electrical cards switches. This issue is resolved
in Releases 4.1.3 and 4.6.
