76-1 config ntp access_group add
Description
This command is used to add the NTP access group.
Format
config ntp access_group add [default | <ipaddr> | <network_address> | <ipv6addr> |
<ipv6networkaddr>] {ignore | noserve | notrust | version | nopeer | noquery | nomodify}
Parameters
default - Specifies to always include the default entry (address 0.0.0.0, mask 0.0.0.0) as the
lowest priority in the list. For IPv6 list, the entry is :: with mask ::.
<ipaddr> - Enter the IPv4 address in dot-decimal notation as the address of a host.
<network_address> - Enter the network address of the access group. The format of the network
address is xxx.xxx.xxx.xxx/y.
<ipv6addr> - Enter the IPv6 address of the access group.
<ipv6networkaddr> - Enter the IPv6 address and subnet prefix of the access group.
ignore - (Optional) Specifies to deny packets of all kinds, including NTP control queries.
noserve - (Optional) Specifies to deny all packets except NTP control queries.
notrust - (Optional) Specifies to deny packets that are not cryptographically authenticated. If the
