alMatrixTopNSourceAddress
Module: RMON2-MIB
OID (symbolic): RMON2-MIB::alMatrixTopNSourceAddress
OID (numeric): 1.3.6.1.2.1.16.17.4.1.3
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 alMatrixTopNProtocolDirLocalIndex.
For example, if the alMatrixTopNProtocolDirLocalIndex 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 alMatrixTopNSourceAddress?
This object holds a byte string representing the source machine's network address in the conversation being tracked, formatted according to the protocol type identified by alMatrixTopNProtocolDirLocalIndex. A network engineer uses this to see which specific device initiated high-traffic flows, pinpointing which hosts are the biggest talkers on the network. For an IP conversation, this might be the byte sequence for 192.168.1.50, identifying a workstation that's sending 1 GB/hour to a server.
