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 or number information:
● For a Management Ethernet interface, enter the keyword
managementethernet.
NOTE:
○ When you configure 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 configured), the source IP
address of the outgoing ICMP error message is modified, although the
packets are not sent out using the configured interface. Because the
management interface is configured 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
specified, 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 information.
● For a 25-Gigabit Ethernet interface, enter the keyword twentyFiveGigE
then the slot/port/subport information.
● For a 40-Gigabit Ethernet interface, enter the keyword fortyGigE then the
slot/port/subport information.
● For a 50-Gigabit Ethernet interface, enter the keyword fiftyGigE then the
slot/port/subport information.
● For a 100-Gigabit Ethernet interface, enter the keyword hundredGigE then
the slot/port information.
