CLI Guide

(ECMP) links, you cannot effectively and optimally use the traceroute and ping
applications to examine the network reachability 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
utilities. You can enable the ICMP unreachable messages to contain the loopback
address of the source device instead of the previous hop's IP address to be able to
easily and quickly identify the device and devices along the path because the DNS
server maps the 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)#ipv6 icmp source-interface tengigabitethernet 0/1
Dell(conf)#
ip max-frag-count

Syntax
ip max-frag-count count
To place no limit on the number of fragments allowed, use the no ip max-frag-
count command.
Parameters
count Enter a number for the number of fragments allowed for re-
assembly. The range is from 2 to 256.
