7.0.14.BASE

Description (partial)

Symptom:
The syslog will be seen, and other than this there will be no functional impact.

RP/0/RP0/CPU0:Aug 21 19:07:53.542 CEST: mibd_interface[179]: %L2-ETHERNET-3-PFC_MIB_ERROR : Unable to fetch requested PFC External MIB data for interface 0x01000048

Conditions:
This can happen in some small time frame that the interfaces in the system and those which are in the cached data do not match. The SNMP response would still be sent, with the data not filled only that particular interface.  A subsequent SNMP query will return the accurate data, since the cache would get refreshed. This is internal implementation and hence, there is no need for a SYSLOG here. This is expected case.
