RMON2 Network Layer - Destination Source Matrix Table

The table "destination source matrix" of the network layer, group 15 of the RMON2 standard, displays traffic statistics issued by pairs of hosts.

For each pair, the table provides the amounts of packets and bytes transmitted by a destination host to a source host at the network layer level (per pair of IP addresses for example) and for each protocol (IP, IPX, AppleTalk etc. ...) .

The hosts with multiple communication protocols or multiple addresses to a single protocol will appear several times in this table for each of the protocols and each of its networks addresses. This is the case of an IP router for example.
To access the table "Destination Source Matrix" click on the icon or select the menu option Layer Network and Destination Source Matrix table.

The table of "Destination Source Matrix" contains the following columns:

Column	Description
Destination Host Name	The destination host name retrieved from the LoriotPro directory. If the host name is unknown LoriotPro is unable to detect or discover the MAC address or this host is dont declared in the directory.
Source Host Name	The source host name retrieved from the LoriotPro directory. If the host name is unknown LoriotPro is unable to detect or discover the MAC address or this host is not declared in the directory.
Destination Address mib object : nlMatrixDSDestAddress	The network destination address for this nlMatrixDSEntry. This is represented as an octet string with specific semantics and length as identified by the protocolDirLocalIndex component of the index. For example, if the protocolDirLocalIndex indicates an encapsulation of IP, this object is encoded as a length octet of 4, followed by the 4 octets of the IP address, in network byte order.
Source Address mib object : nlMatrixDSSourceAddress	The network source address for this nlMatrixDSEntry. This is represented as an octet string with specific semantics and length as identified by the protocolDirLocalIndex component of the index. For example, if the protocolDirLocalIndex indicates an encapsulation of IP, this object is encoded as a length octet of 4, followed by the 4 octets of the IP address, in network byte order.
Protocol mib object : nlMatrixTopNProtocolDirLocalIndex	The protocol at the network layer level. The protocolDirLocalIndex value in the index identifies the network layer protocol of the nlHostAddress
D to S Packets mib object : nlMatrixDSPkts	The number of packets without errors transmitted from the destination address to the source address since this entry was added to the nlMatrixDDTable. Note that this is the number of link-layer packets, so if a single network-layer packet is fragmented into several link-layer frames, this counter is incremented several times.
D to S Octets mib object : nlMatrixDSOctets	The number of octets transmitted from the destination address to the source address since this entry was added to the nlMatrixDSTable (excluding framing bits, but including FCS octets), excluding octets in packets that contained errors. Note that this doesn't count just those octets in the particular protocol frames but includes the entire packet that contained the protocol.
