ip source-interface

Syntax

ip source-interface {all | ubt} {interface <IFNAME> | <IPV4-ADDR>} [vrf <VRF-NAME>]

no ip source-interface {all | ubt} {interface <IFNAME> | <IPV4-ADDR>} [vrf <VRF-NAME>]

Description

Sets a single source IP address for UBT. This ensures that all traffic sent by UBT has the same source IP address, regardless of how it egresses the switch.

This command provides two ways to set the source IP addresses: either by specifying a static IP address, or by using the address assigned to a switch interface. If you define both options, then the static IP address takes precedence.

The no form of this command deletes the single source IP address for UBT.

Parameters

all

When used no other parameters are required.

interface <IFNAME>

Specifies the name of the interface from which UBT obtains its source IP address. The interface must have a valid IP address assigned to it. If the interface has both a primary and secondary IP address, the primary IP address is used.

<IPV4-ADDR>

Specifies the source IP address to use for UBT. The IP address must be defined on the switch, and it must exist on the specified VRF, Default: default. Specify the address in IPv4 format (x.x.x.x), where x is a decimal number from 0 to 255.

vrf <VRF-NAME>

Specifies the name of the VRF from which UBT sets its source IP address.

Authority

Administrators or local user group members with execution rights for this command.

Examples

Setting interface 1/1/7 as the source address for UBT for VRF default:

switch(config)# ip source-interface ubt interface 1/1/7 vrf default

Deleting the configured source interface 1/1/7 as the source address for UBT for VRF default:

switch(config)# no ip source-interface ubt interface 1/1/7 vrf default

Specifying the static IP address 1.1.1.1 as the source address for UBT for VRF default:

switch(config)# ip source-interface ubt 1.1.1.1 vrf default

Deleting the configured ip address as the source address for UBT for VRF default:

switch(config)# no ip source-interface ubt 1.1.1.1 vrf default
