To configure SNMPv3 settings for the user account:
1.
Use User Name to specify the user account to be configured.
2.

selected user account. The valid Authentication Protocols are None, MD5 or SHA:
selected user account. The valid Authentication Protocols are None, MD5 or SHA:
•
If you select None, the user will be unable to access the SNMP data from an SNMP
browser.
•
If you select MD5 or SHA, the user login password will be used as the SNMPv3
authentication password, and you must therefore specify a password, and it must be
eight characters long.

LLDP
The IEEE 802.1AB-defined standard, Link Layer Discovery Protocol (LLDP), allows stations
on an 802 LAN to advertise major capabilities and physical descriptions. This information is
viewed by a network manager to identify system topology and detect bad configurations on
the LAN.

the LAN.
From the LLDP link, you can access the following pages:
LLDP is a one-way protocol; there are no request/response sequences. Information is
advertised by stations implementing the transmit function, and is received and processed by
stations implementing the receive function. The transmit and receive functions can be
enabled/disabled separately per port. By default, both transmit and receive are disabled on
all ports. The application is responsible for starting each transmit and receive state machine
appropriately, based on the configured status and operational state of the port.
