Known Behavior
If you have enabled ipInterface logging at a priority of debug, the
acknowledgment that an interface has been deleted from the line modules can
return to the SRP module after the layers beneath IP have deleted their
interfaces. Consequently, the original name of the interface cannot be resolved
or displayed in the log, and the system instead displays the ifIndex of the IP
interface. This behavior has no functional effect other than that the log is
misleading. However, previous log events indicate that the interface deletion
was beginning.
When you want to use a configuration script to configure IP shared interfaces
that reference a physical interface, you must issue the service show
configuration format 2 command before you generate the script. If the default
show configuration format (format 1) is enabled instead, the generated script
cannot properly configure the IP shared interfaces because they are created
before the physical interfaces. To properly configure the shared interfaces in
this event, run the generated format 1 script twice.
When you issue the show ip forwarding-table command for a particular slot, it
is normal and appropriate behavior when the Status field indicates Valid while
the Load Errors field is increasing daily for that VR. The Load Errors field
records any failed routing table distribution attempt as an error. Attempts can
fail for many reasons during normal operation; a failed attempt does not
necessarily indicate a problem. It is normal to see many load errors per day. If
the Status field indicates Invalid, then the routing table distribution has failed
constantly for that VR and a real problem exists. You might occasionally see a
status of Updating. However, if the Status field always indicates Updating, then
again the routing table distribution has failed constantly for that VR, and a real
problem exists.
The enhancement to the CLI to support unnumbered reference to any kind of
interface rather than just loopback interfaces has consequences such as the
following: [Defect ID 47743]
If the references to shared interfaces appear in the show configuration
output before the configuration for the interfaces they refer to, trying to
restore such a configuration with a script generated from show
configuration generates errors like the following:
% Error, line 3929:
host1(config-if)#ip share-interface FastEthernet 3/0.2
% No such interface
Unnumbered interfaces that refer to nonloopback interfaces (for example,
ip unnumbered fastEthernet 3/0.2) and that appear in the show
configuration output before the interface referred to might generate
similar no such interface errors.
Work-around: Run the script twice.
