Configuring NTP
7
Enable or disable the VLAN containment for NTP
To enable or disable the VLAN containment for NTP, use the access-control vlan command. To
remove the specified NTP VLAN configuration, use the no form of this command.
NOTE
The management interface is not part of any VLAN. When configuring the VLAN containment for NTP,
it will not use the management interface to send or receive the NTP packets.
Brocade(config-ntp)# access-control vlan 100
Syntax: [no] access-control vlan vlan-id
The vlan-id parameter specifies the VLAN ID number.
Configuring the NTP client
To configure the device in client mode and specify the NTP servers to synchronize the system clock,
use the server command. A maximum 8 NTP servers can be configured. To configured NTP server,
use the no form of this command.
Brocade(config-ntp)#server 10.2.3.4 key 1234
Syntax: # [no] server ipv4 address | ipv6 address [version 3|4] [key key id] [minpoll interval]
[maxpoll interval]
The ipv4 address | ipv6 address parameter is the IP address of the server providing the clock
synchronization.
The version 3|4 option defines the Network Time Protocol (NTP) version number. If this option is
not specified, then it defaults to 4.
The key key id option defines the authentication key. By default, no authentication key is
configured.
The minpoll interval option is the shortest polling interval. The range is from 4 through 17. Default is
6. The interval argument is power of 2 (4=16s, 5=32s, 6=64s, 7=128s, 8=256s, 9=512s etc.).
The maxpoll interval option is the longest polling interval. The range is 4 through 17. Default is 10.
The interval argument is calculated by the power of 2 (4=16s, 5=32s, 6=64s, 7=128s, 8=256s,
9=512s etc.).
