Command Reference Guide
ip sntp source-interface <interface>
Use the ip sntp source-interface command to specify a source interface for Simple Network Time
Protocol (SNTP) traffic originated by the unit. The IP address of the specified interface will be used to
source all SNTP traffic. Use the no form of this command if you do not wish to override the default source
IP address.
Syntax Description
<interface>
Default Values
By default, no SNTP source interface is defined.

Functional Notes
This command allows you to override the sender field in the IP packet. If you have multiple interfaces in
your unit, changing the sender tells the receiver where to send replies. This functionality can also be used
to allow packets to get through firewalls that would normally block the flow.
Usage Examples
The following example configures the unit to use the loopback 1 interface as the source IP for SNTP
traffic:
(config)#ip sntp source-interface loopback 1
60000CRG0-35E
Specifies the source interface for SNTP traffic. Specify an interface in the
format <interface type [slot/port | slot/port.subinterface id | interface id |
interface id.subinterface id | ap | ap/radio | ap/radio.vap]>. For example, for
a T1 interface, use t1 0/1; for an Ethernet subinterface, use eth 0/1.1; for a
PPP interface, use ppp 1; for an ATM subinterface, use atm 1.1; and for a
wireless virtual access point, use dot11ap 1/1.1. Type ip sntp
source-interface ? for a complete list of valid interfaces.
