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.
This functionality is supported on the , , S6000, and platforms.
Syntax

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 a Loopback interface, enter the keyword loopback.
The range is from 0 to 16383.
•
For a 1-Gigabit Ethernet interface, enter the keyword
GigabitEthernet.
•
For a Port Channel interface, enter the keywords port-
channel then a number. The range is from 1 to 128.
•
For a 10-Gigabit Ethernet interface, enter the keyword
TenGigabitEthernet.
•
For a 40-Gigabit Ethernet interface, enter the keyword
fortyGigE.
•
For a VLAN interface, enter the keyword vlan. The range
is from 1 to 4094.
