Description (partial)


SNMP ifIndex does not exist for MFR subinterfaces on CHOC12/DS1-IR-SC ISE line card after removal and reinsertion (OIR) of the card.


This was seen in release 12.0(32)SY1 when using a configuration with a large number of serial interfaces configured, including a 8xDS1 MFR bundle.  The MFR interface had a corresponding point-to-point subinterface with one DLCI defined.  The subinterface was pollable before removal and insertion of the card, but the ifIndex is missing afterward.
