126 ExtremeWare 7.7 Command Reference Guide
Commands for Managing the Switch
The following can also be configured on the switch for version 6.0 and higher:
• SNMP read access —The ability to read SNMP information can be restricted through the use of an
access profile. An access profile permits or denies a named list of IP addresses and subnet masks.
• SNMP read/write access —The ability to read and write SNMP information can be restricted through
the use of an access profile. An access profile permits or denies a named list of IP addresses and
subnet masks.
Telnet
Telnet allows you to access the switch remotely using TCP/IP through one of the switch ports or a
workstation with a Telnet facility. If you access the switch via Telnet, you will use the command line
interface (CLI) to manage the switch and modify switch configurations.
Simple Network Time Protocol
ExtremeWare supports the client portion of the Simple Network Time Protocol (SNTP) Version 3 based
on RFC1769. SNTP can be used by the switch to update and synchronize its internal clock from a
Network Time Protocol (NTP) server. When enabled, the switch sends out a periodic query to the
indicated NTP server, or the switch listens to broadcast NTP updates. In addition, the switch supports
the configured setting for Greenwich Mean time (GMT) offset and the use of Daylight Saving Time.
These features have been tested for year 2000 compliance.
ExtremeWare Vista
ExtremeWare Vista is a device management software running in the switch that allows you to access the
switch over a TCP/IP network using a standard web browser. ExtremeWare Vista provides a subset of
the CLI commands available for configuring and monitoring the switch. If a particular command is not
available using ExtremeWare Vista, you must use the CLI to access the desired functionality.
