Service Manual

loopback IP address to the hostname and does not translate the IP address of every interface of the
switch to the hostname.
Example
Dell(conf)# ip icmp source-interface tengigabitethernet 1/1
Dell(conf)#
ipv6 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 IPv6 packets.
Syntax
ipv6 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 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[/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.
Defaults Not configured.

Usage
Information
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.
