MES1000, MES2000 Ethernet Switches 15
SNTP
(Simple Network Time
Protocol)
SNTP protocol is a network time synchronization protocol; it allows to perform
time synchronization of the network device with the server with accuracy up to
1ms.
Traceroute is a service function, that allows to display data transfer routes in IP
networks.
Controlled access
management—privilege
levels
Administrator can define privilege levels for users of the device and settings for
each privilege level (read-only—level 1, full access—level 15).
Management interface
blocking
The switch can block access to each management interface (SNMP, Telnet, SSH).
Blocking can be set independently for each type of access:
Telnet(CLI over Telnet Session)
Secure Shell (CLI over SSH)
SNMP
For local authentication, passwords can be stored in the switch database.
IP address filtering for
SNMP
Access via SNMP is allowed only for specific IP addresses, that are the part of
SNMP community.
RADIUS protocol is used for authentication, authorization and accounting. RADIUS
server operates with the user database, that contains authentication data for each
user. Switches contain client part of the RADIUS protocol.
TACACS+
(Terminal Access
Controller Access Control
System)
Device supports client authentication with TACACS+ protocol. TACACS+ protocol
provides centralized security system for authentication of users, gaining access to
the device, and centralized management system, while ensuring compatibility with
RADIUS and other authentication processes.
SSH server functionality allows SSH client to establish secure connection to the
device for management purposes.
This function allows to create macrocommands—command sets—and apply them
for the time-sensitive device management.
2.2.8 Additional functions
The table lists the additional device functions.
Table 2.8 —Additional device functions
Virtual cable tester
(VCT)
Network switches are equipped with the hardware and software tools, that allow
them to perform the following cable testing functions—VCT:
– Determine the communication faults when the copper-wire cable is used
(break/short-circuit)
– Test results reporting
Optical transceiver
diagnostics
The device allows to test the optical transceiver. During testing, the device
monitors the current, power voltage and transceiver temperature, receiving and
transmitting optical signal power. The diagnostics is available only for transceivers
with the Digital Diagnostics Monitoring (DDM) support.
This mechanism allows to reduce the device power consumption by switching
inactive electric ports to the economy mode.
Active monitoring technology used for measuring network performance and data
transmission quality. Supported operations: ICMP Echo, UDP Jitter.
