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 configurable only 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 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.

Not configured.

platforms.

You can enable the mechanism to configure the source or the originating interface from which the packet (the device that generates the ICMP error messages) is received by the switch to send the loopback address instead of its source IP address to be used in the ICMP unreachable messages and in the traceroute command output. The loopback address must be unique in a particular domain.

In network environments that contain a large number of devices, ranging up to thousands of systems, and with each device configured for equal-cost multipath (ECMP) links, you cannot effectively and optimally use the traceroute and ping applications to examine the network reachablity and identify any broken links for diagnostic purposes. In such cases, if the reply that is obtained from each hop on the network path contains the IP address of the adjacent, neighboring interface from which the packet is received, it is difficult to employ the ping and traceroute
