show pfe statistics ip6

Syntax



show pfe statistics ip6 
<icmp>

Syntax (Routing Matrix)



show pfe statistics ip6 
<fpc slot>

<icmp>

<  lcc number>

Release Information

Command introduced before JUNOS Release 7.4.

Description

Display Packet Forwarding Engine IPv6 statistics.

Options

none — Display all Packet Forwarding Engine IPv6 statistics.

fpc slot — (Routing matrix only) (Optional) Display statistics for a Flexible PIC Concentrator slot. If you specify the number of a T640 routing node by using the lcc number option (the recommended method), replace slot with a value from 0 through 7. Otherwise, replace slot with a value from 0 through 31. For example, the following commands have the same result:

user@host> show pfe statistics ip6 fpc 1 lcc 1
user@host> show pfe statistics ip6 fpc 9

icmp — (Optional) Display Packet Forwarding Engine IP ICMP statistics.

lcc number — (Routing matrix only) (Optional) Display statistics for a specific T640 routing node (or line-card chassis) that is connected to a TX Matrix platform. Replace number with a value from 0 through 3.

Required Privilege Level

Output Fields

Table 96 lists the output fields for the show pfe statistics ip6 command. Output fields are listed in the approximate order in which they appear.

Table 96: show pfe statistics ip6 Output Fields

Field Name	Field Description
ICMP6 Statistics	ICMP6 statistics, including the following: requests—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 throttled icmps field description.) network unreachables—When route lookups fail, ICMP packets are sent to the source. These packets are ICMP Type= Destination 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. redirects—Number of ICMP errors sent with Type=Redirect (5). mtu exceeded—Number of ICMP errors sent with Type=Source Quench (4). icmp/option handoffs—Number of packets that the PFE hardware requests the PFE software to process.
ICMP6 errors	ICMP6 errors, including the following: unknown unreachables—Unknown code (greater than 16) found for an unknown unreachable type ICMP error. unsupported ICMP type—Any ICMP type other than UNREACH, REDIRECT, TIME_EXCEED, and PARAM_PROB. unprocessed redirects—When trying to find the neighbor to send redirects to, the PFE could not find the next-hop information. invalid ICMP type—Any ICMP type other than UNREACH, REDIRECT, TIME_EXCEED, and PARAM_PROB. invalid protocol—An incorrect protocol was detected by the ICMP processor. bad input interface if1—The PFE software cannot map the interface index supplied by the chips to a proper data structure in the microkernel. throttled icmps—Number of requests dropped because of rate limiting by the PFE. runts—Number of packets for which the IP header length is less than the minimum length that is supported.
ICMP6 Discards	ICMP6 discard statistics, including the following: multicasts—ICMP packets are not sent for link-layer multicast packets. These are counted as invalid source addresses (not a unicast address or all zeros). bad source addresses—ICMP packets were received from an invalid source address (not a unicast address or all zeros). bad dest addresses—ICMP packets were sent to an invalid destination address (not a unicast address or all zeros). IP fragments—ICMP responses are sent only for the first fragments. The rest do not receive a response. This is the count for ICMP requests that receive no response. ICMP errors—Number of ICMP error packets.

ICMP6 Discards

ICMP6 discard statistics, including the following:
