It is possible to place restriction flags on specific 

NTP

 entities in relation to the switch. Restric-

tion flags prevent messages or information coming from the 

NTP

 entity from affecting the 

switch.

To remove a restriction flag from an 

NTP

 entity, enter the 

 command as shown:

where 

 is the 

IP

 address of the 

NTP

 entity, 

 is the entity’s subnet mask, and 

 is the specific flag you want to remove from the entity. For example, to remove 

an 

 restriction from an entity with address 1.1.1.1 and a subnet mask of 255.255.0.0, 

enter the following:

To remove an entry completely from the restriction list, enter the 

 command in the 

following manner:

where 

 is the 

IP

 address of the 

NTP

 entity, and 

 is the entity’s subnet mask. 

For example to remove an entity with address 1.1.1.1 and a subnet mask of 255.255.0.0, enter 
the following:

This entity will no longer be listed in the restriction list and has no restriction flags placed on 
messages it sends to the switch.

The 

 command allows you to set a trap receiver for the given address and port 

number. The trap receiver will log event messages and other information for the server in a 
log file.

To create a trap receiver, enter the 

 command in the following manner:

where address is the IP address of the switch. There are two optional items you can specify:

 

The port on the switch used for sending 

NTP

 messages. If no 

port is specified, a default port of 18447 is used.

♦ Note ♦

This is the 

TCP

 and 

UDP

 definition of a port, not a 

switch interface port.

The local interface address for this 

NTP

 entity. If no interface is 

specified, the interface for the local 

NTP

 entity is used. For
