RMON Network Layer - Host TOP N Table

The Host Top N table of the network layer, group 15 subgroup 5 from RMON 2, provides a ranking of the traffic between pairs of hosts based on the packet rate or the octet rate between them and in both directions and filtered by network protocol (IP, IPX, AppleTalk etc.).

To access the table "Host Top N table" click on the icon or select the menu option Layer Network andHost Top N table.

The table of "Host Top N table" contains the following columns:

Column	Description
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.
Source Address mib object : nlMatrixTopNSourceAddress		The network-layer address of the source host in this conversation. This is represented as an octet string with specific semantics and length as identified by the associated lMatrixTopNProtocolDirLocalIndex. 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.
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.
Destination Address mib object : nlMatrixTopNDestAddress		The network-layer address of the destination host in this conversation. This is represented as an octet string with specific semantics and length as identified by the associated nlMatrixTopNProtocolDirLocalIndex. For example, if the nlMatrixTopNProtocolDirLocalIndex 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
Packet Rate mib object : nlMatrixTopNPktRate		The number of packets seen from the source host to the destination host during this sampling interval, counted using the rules for counting the nlMatrixSDPkts object. If the value of nlMatrixTopNControlRateBase is nlMatrixTopNPkts, this variable will be used to sort this report.
Reverse Packet Rate mib object : nlMatrixTopNReversePktRate		The number of packets seen from the destination host to the source host during this sampling interval, counted using the rules for counting the nlMatrixSDPkts object. (Note that the corresponding nlMatrixSDPkts object selected is the one whose source address is equal to nlMatrixTopNDestAddress and whose destination address is equal to nlMatrixTopNSourceAddress.) Note that if the value of nlMatrixTopNControlRateBase is equal to nlMatrixTopNPkts, the sort of topN entries is based entirely on nlMatrixTopNPktRate, and not on the value of this object.
Octet Rate mib object : nlMatrixTopNOctetRate		The number of octets seen from the source host to the destination host during this sampling interval, counted using the rules for counting the nlMatrixSDOctets object. If the value of nlMatrixTopNControlRateBase is nlMatrixTopNOctets, this variable will be used to sort this report.
Reverse Octet Rate mib object : nlMatrixTopNReverseOctetRate		The number of octets seen from the destination host to the source host during this sampling interval, counted using the rules for counting the nlMatrixDSOctets object. (Note that the corresponding nlMatrixSDOctets object selected is the one whose source address is equal to nlMatrixTopNDestAddress and whose destination address is equal to nlMatrixTopNSourceAddress.) Note that if the value of nlMatrixTopNControlRateBase is equal to nlMatrixTopNOctets, the sort of topN entries is based entirely on nlMatrixTopNOctetRate, and not on the value of this object.
