—Number of ICMP notifications sent to the PFE. If a throttler is configured, the number of

notifications might not reflect all requests made. (See the
—When route lookups fail, ICMP packets are sent to the source. These packets

are ICMP TypeDestination Unreachable (3) and ICMP Code=Network Unreachable (0).
ttl expired —Number of notifications processed as a result of time-to-live (TTL) expiration packets.
ttl captured —Number of TTL expired packets sent by PFE interfaces to the Routing Engine.
—Number of ICMP errors sent with Type=Redirect (5).

—Number of ICMP errors sent with Type=Source Quench (4).
mtu exceeded
—Number of packets that the PFE hardware requests the PFE software to
icmp/option handoffs
process.
unknown unreachables —Unknown code (greater than 16) found for an unknown unreachable type
ICMP error.
—Any ICMP type other than UNREACH, REDIRECT, TIME_EXCEED, and
unsupported ICMP type

—When trying to find the neighbor to send redirects to, the PFE could not find

—Any ICMP type other than UNREACH, REDIRECT, TIME_EXCEED, and
invalid ICMP type
PARAM_PROB.
—An incorrect protocol was detected by the ICMP processor.

—ICMP packets are not sent for link-layer multicast packets. These are counted as invalid

—ICMP packets were sent to an invalid destination address (not a unicast address

—ICMP responses are sent only for the first fragments. The rest do not receive a
