NTP Server Configuration commands

Command

Description

ntp timezone

<hh:mm>

Configures the NTP time zone offset from Greenwich Mean Time (GMT),

in hours and minutes. The offset format is HH:MM.

Command mode

: Global configuration

[no] ntp daylightsavings

Disables or enables daylight saving time in the system clock. When

enabled, the switch will add an extra hour to the system clock so that it

is consistent with the local clock. By default, this option is disabled.

Command mode

: Global configuration

ntp enable

Enables the NTP synchronization service.

Command mode

: Global configuration

no ntp enable

Disables the NTP synchronization service. This is the default.

Command mode

: Global configuration

show ntp

Displays the current NTP service settings.

Command mode

: All

System SNMP configuration

The switch software supports SNMP-based network management. In SNMP model of network management, a

management station (client/manager) accesses a set of variables known as MIBs (Management Information Base)

provided by the managed device (agent). If you are running an SNMP network management station on your network,

you can manage the switch using the following standard SNMP MIBs:

•

MIB II (RFC 1213)

•

Ethernet MIB (RFC 1643)

•

Bridge MIB (RFC 1493)

An SNMP agent is a software process on the managed device that listens on UDP port 161 for SNMP messages.

Each SNMP message sent to the agent contains a list of management objects to retrieve or to modify.

•

SNMP parameters that can be modified include:

•

System name

•

System location

•

System contact

•

Use of the SNMP system authentication trap function

•

Read community string

•

Write community string

The following table describes the System SNMP Configuration commands. The following sections provide more

detailed information and commands.

System SNMP Configuration commands

Command

Description

hostname

<1-64

characters>

Configures the name for the system. The name can have a maximum of 64 characters.

Command mode

: Global configuration

snmp-server location

<1-64 characters>

Configures the name of the system location. The location can have a maximum of 64

characters.

snmp-server contact

<1-

64 characters>

Configures the name of the system contact. The contact can have a maximum of 64

characters.

Command mod

: Global configuration

snmp-server read-

community

<1-32

characters>

Configures the SNMP read community string. The read community string controls SNMP

“get” access to the switch. It can have a maximum of 32 characters. The default read

community string is

public
