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 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 a 10-Gigabit Ethernet interface, enter the keyword
TenGigabitEthernet then the slot/port[/subport]
information.
• For a 40-Gigabit Ethernet interface, enter the keyword
fortyGigE then the slot/port information.
• For a Loopback interface, enter the keyword loopback
then a number from 0 to 16383.
• For a port channel interface, enter the keywords port-
channel then a number.
• For a VLAN interface, enter the keyword vlan then a
number from 1 to 4094.
