nlMatrixTopNSourceAddress
Module: RMON2-MIB
OID (symbolic): RMON2-MIB::nlMatrixTopNSourceAddress
OID (numeric): 1.3.6.1.2.1.16.15.5.1.3
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-only
Description: 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 nlMatrixTopNProtocolDirLocalIndex.
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.
What is nlMatrixTopNSourceAddress?
This byte string holds the network-layer address (e.g., IP address) of the host originating traffic in a top-N conversation pair. For IP, it's encoded as length octet plus four octets of the IP in network order. Engineers use this to identify which device is sending the most traffic—for example, a source address of 192.168.1.100 flagged as a top talker might indicate a file server.
