CiscoInterfaceIndexList
This textual convention contains a list of ifIndex values. Each ifIndex value is represented by four octets. Every set of four octets represents a value of an instance of ifIndex object, defined in IF-MIB, corresponding to a particular interface. For example, the first octet to the fourth octet represent a value of the instance of ifIndex object for the first interface in the list. The fifth octet to the eighth octet represent a value of the instance of ifIndex object for the second interface in the list. Up to 64 interfaces can be represented by this textual convention.
