ntp access-group

The ntp access-group match-all command causes the access group options to be scanned in the

following order, from least restrictive to most restrictive: peer, serve, serve-only, query-only. If the

incoming packet does not match the peer access group, the packet goes to the serve access group to be

processed. If the packet does not match the serve access group, it goes to the next access group and so

on. This command also enables IPv6 access group processing.

The ntp access-group match-all command is available beginning with Cisco NX-OS Release 6.2(2). If

you enter the no form of this command, do not enter this command or create an access group using an

earlier version of Cisco NX-OS. ACL processing stops and does not continue to the next access group

option if the incoming packet does not match the peer access group or if NTP matches a deny ACL rule

in a configured peer.

This command does not require a license.

This example shows how to configure a peer access group for NTP:

switch# config t

switch(config)# ntp access-group peer Admin_Group_123

switch(config)#

This example shows how to remove an NTP peer access group:

switch# config t

switch(config)# no ntp access-group peer Admin_Group_123

switch(config)#
