ip icmp source-interface
Enable the ICMP error and unreachable messages to be sent with the source interface IP address, such as the loopback address, instead of
the hops of the preceding devices along the network path to be used for easy debugging and diagnosis of network disconnections and
reachability problems with IPv4 packets.
Syntax
ip icmp source-interface interface
Parameters
interface Enter one of the following keywords and slot/port[/subport] or number information:
• For a Management Ethernet interface, enter the keyword managementethernet.
NOTE:
– When you congure the capability to enable the loopback IP address to be
sent for easy debugging and diagnosis (IP addresses of the devices for
which the ICMP source interface is congured), the source IP address of
the outgoing ICMP error message is modied, although the packets are
not sent out using the congured interface. Because the management
interface is congured without any parameters such as the IP address, it is
treated to the management interface of the primary unit or the existing
unit.
– For ICMP, a user can specify one source-interface for each VRF and let it
be the default, management or any other VRF created. For other protocols
(Telnet, SSH, FTP, TFTP), where the source interface can be specied,
only one interface can be chosen. This is for all VRFs combined.
• For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then
the slot/port/subport[/subport] information.
• For a 40-Gigabit Ethernet interface, enter the keyword fortyGigE then the slot/
port information.
