ICMP Support

Internet Control Message Protocol (ICMP) provides a mechanism that enables a router or destination host to report an error in data traffic processing to the original source of the packet. For this release, the E-series router supports ICMP for use in the IPv6 ping and traceroute commands.

The ping and traceroute commands help you determine destination reachability within a network.

• Use the ping ipv6 command to send an ICMP echo request packet. In the following example, the request packet is sent to address 1::1 with a data size of 200 and a timeout value of 10 seconds:

  host1#ping ipv6 1::1 data-size 200 timeout 10

• Use the traceroute ipv6 command to discover routes that router packets follow when traveling to their destination. In the following example, the trace destination address is 1::1, the maximum number of hops of the trace is 20, and the timeout value is 10 seconds:

  host1#traceroute ipv6 1::1 hop-limit 20 timeout 10
