3.2.10. ICMP Statistics Tables

There are two sets of statistics for ICMP. The first contains a simple set of counters to track the number of ICMP messages and errors processed by this entity.

The second supplies more detail about the ICMP messages processed by this entity. Its index is formed from two sub-ids. The first represents the address type (IPv4 and IPv6), and the second represents the particular message type being counted. A given row need not be instantiated unless a message of that type has been processed, i.e., the row for icmpMsgStatsType=X MAY be instantiated before but MUST be instantated after the first message with Type=X is received or transmitted. After receiving or transmitting any succeeding messages with Type=X, the relevant counter must be incremented.

Both of these tables are required for all entities.
