Configuration Backup &
Restoration
Make a copy of the Switch’s configuration and put it back on
the Switch later if you decide you want to revert back to an
earlier configuration.
Cluster Management Cluster management (also known as iStacking) allows you to
manage switches through one switch, called the cluster
manager. The switches must be directly connected and be in
the same VLAN group so as to be able to communicate with
one another.
LLDP (Link Layer
Discovery Protocol)
The LLDP (Link Layer Discovery Protocol) is a layer 2 protocol.
It allows a network device to advertise its identity and
capabilities on the local network. It also allows the device to
maintain and store information from adjacent devices which
are directly connected to the network device. This helps an
administrator discover network changes and perform necessary
network reconfiguration and management.
The device information is encapsulated in the LLDPDUs (LLDP
data units) in the form of TLV (Type, Length, Value). Device
information carried in the received LLDPDUs is stored in the
standard MIB.
OAM (Operations,
Administration and
Maintenance)
Ethernet OAM as described in IEEE 802.3ah is a link monitoring
protocol. It utilizes OAM Protocol Data Units or OAM PDU’s to
transmit link status information between directly connected
Ethernet devices. Both devices must support IEEE 802.3ah.
Because link layer Ethernet OAM operates at layer two of the
OSI (Open Systems Interconnection Basic Reference) model,
neither IP or SNMP are necessary to monitor or troubleshoot
network connection problems.
