Using The Simple Network Time Protocol - Extreme Networks ExtremeWare XOS Guide Manual

Managing the Switch
To remove the association of a filter profile or all filter profiles with a parameter name, use the
following command:
configure snmpv3 delete filter-profile [all |[[hex <hex_profile_name>] |
<profile_name>] {param [[hex <hex_param_name>] | <param_name>}]]
Notification Tags
When you create a target address, either you associate a list of notification tags with the target or by
default, the defaultNotify tag is associated with the target. When the system generates notifications, only
those targets associated with tags currently in the standard MIB table, called snmpNotifyTable, are
notified.
To add an entry to the table, use the following command:
configure snmpv3 add notify [[hex <hex_notify_name>] | <notify_name>] tag [[hex
<hex_tag>] | <tag>] {volatile}
Any targets associated with tags in the snmpNotifyTable are notified, based on the filter profile associated
with the target.
To display the notifications that are set, use the following command:
show snmpv3 notify {[[hex <hex_notify_name>] | <notify_name>]}
To delete an entry from the snmpNotifyTable, use the following command:
configure snmpv3 delete notify [{[[hex <hex_notify_name>] | <notify_name>]} | all-non-
defaults]
You cannot delete the default entry from the table, so any targets configured with the defaultNotify tag
will always receive notifications consistent with any filter profile specified.
Configuring Notifications
Because the target parameters name points to a number of objects used for notifications, configure the
target parameter name entry first. You can then configure the target address, filter profiles and filters,
and any necessary notification tags.

Using the Simple Network Time Protocol

ExtremeWare XOS 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. After SNTP has been 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.
