Viewing and configuring SNTP (CLI)
Syntax:
show sntp
Lists both the time synchronization method (TimeP,
SNTP, or
None) and the SNTP configuration, even if SNTP is not the selected time protocol.
If you configure the switch with SNTP as the time synchronization method, then enable SNTP in broadcast mode with the default poll interval,
show sntp lists the following:
SNTP configuration when SNTP is the selected time synchronization method
switch(config)# show sntp SNTP Configuration Time Sync Mode: Sntp SNTP Mode : Unicast Poll Interval (sec) [720] : 719 Priority SNTP Server Address Protocol Version -------- ------------------------------ ---------------- 1 2001:db8::215:60ff:fe79:8980 7 2 10.255.5.24 3 3 fe80::123%vlan10 3
In the factory-default configuration (where TimeP is the selected time synchronization method),
show sntp still lists the SNTP configuration, even though it is not currently in use. In
SNTP configuration when SNTP is not the selected time synchronization method, even though TimeP is the current time synchronous method, the switch maintains the SNTP configuration.
SNTP configuration when SNTP is not the selected time synchronization method
switch(config)# show sntp SNTP Configuration Time Sync Mode: Timep SNTP Mode : Unicast Poll Interval (sec) [720] : 719 Priority SNTP Server Address Protocol Version -------- ------------------------------ ---------------- 1 2001:db8::215:60ff:fe79:8980 7 2 10.255.5.24 3 3 fe80::123%vlan10 3
Syntax:
show management
This command can help you to easily examine and compare the IP addressing on the switch. It lists the IP addresses for all time servers configured on the switch, plus the IP addresses and default gateway for all VLANs configured on the switch.
