The frames also contain a MAC address ( SMAC address ), which shows the MAC address of the equipment sending
the frame. The SMAC address is used by the switch to automatically update the MAC table with these dynamic MAC
addresses. Dynamic entries are removed from the MAC table if no frame with the corresponding SMAC address have
been seen after a configurable age time.
MD5
MD5 is an acronym for Message-Digest algorithm 5. MD5 is a message digest algorithm, used cryptographic hash
function with a 128-bit hash value. It was designed by Ron Rivest in 1991. MD5 is officially defined in RFC 1321 - The
MD5 Message-Digest Algorithm.
Mirroring
For debugging network problems or monitoring network traffic, the switch system can be configured to mirror frames
from multiple ports to a mirror port. (In this context, mirroring a frame is the same as copying the frame.)
Both incoming (source) and outgoing (destination) frames can be mirrored to the mirror port.
N
NetBIOS
NetBIOS is an acronym for Network Basic Input/Output System. It is a program that allows applications on separate
computers to communicate within a Local Area Network (LAN), and it is not supported on a Wide Area Network (WAN).
The NetBIOS giving each computer in the network both a NetBIOS name and an IP address corresponding to a
different host name, provides the session and transport services described in the Open Systems Interconnection (OSI)
model.
NFS
NFS is an acronym for Network File System. It allows hosts to mount partitions on a remote system and use them as
though they are local file systems.
NFS allows the system administrator to store resources in a central location on the network, providing authorized users
continuous access to them, which means NFS supports sharing of files, printers, and other resources as persistent
storage over a computer network.
O
Optional TLVs.
A LLDP frame contains multiple TLVs
For some TLVs it is configurable if the switch shall include the TLV in the LLDP frame. These TLVs are known as
