TFTP Trivial File Transfer Protocol
The device supports boot image, software, and configuration upload/download via TFTP.
Remote Monitoring
Remote Monitoring
(RMON) is an extension to SNMP, which provides comprehensive network
traffic
monitoring capabilities (as opposed to SNMP which allows network device
management and
monitoring). RMON is a standard MIB that defines current and historical MAC-layer statistics and
control objects, allowing real-time information to be captured across the entire network.
For more information, see "Viewing Statistics."
Command Line Interface
Command Line Interface
(CLI) syntax and semantics conform as much as possible to common
industry practice. CLI is composed of mandatory and optional elements. The CLI interpreter
provides command and keyword completion to assist user and shorten typing.
Syslog
Syslog is a protocol that enables event notifications to be sent to a set of remote servers, where they
can be stored, examined and acted upon. The system sends notifications of significant events in
real time, and keeps a record of these events for after-the-fact usage.
For more information on Syslog, see "Managing Logs."
SNTP
The Simple Network Time Protocol (SNTP) assures accurate network Ethernet Switch clock time
synchronization up to the millisecond. Time synchronization is performed by a network SNTP
server. Time sources are established by Stratums. Stratums define the distance from the reference
clock. The higher the stratum (where zero is the highest), the more accurate the clock.
For more information, see "Configuring SNTP Settings."
Domain Name System
Domain Name System (DNS) converts user-defined domain names into IP addresses. Each time a
domain name is assigned the DNS service translates the name into a numeric IP address. For
example, www.ipexample.com is translated to 192.87.56.2. DNS servers maintain domain name
databases and their corresponding IP addresses.
For more information, see "Configuring Domain Name Systems".
Traceroute
Traceroute discovers IP routes that packets were forwarded along during the forwarding process.
The CLI Traceroute utility can be executed from either the user-exec or privileged modes.
