show pfe statistics ip
Syntax
show pfe statistics ip <icmp | options>
Syntax (TX Matrix and TX Matrix Plus Routers)
show pfe statistics ip <fpc slot> <icmp | options> <lcc number>
Release Information
Command introduced before Junos OS Release
7.4.
Command introduced in Junos OS Release 9.0 for EX Series switches.
Description
Display IPv4 Packet Forwarding Engine statistics.
Options
none | — | Display all IPv4
Packet Forward Engine statistics. |
fpc slot | — | (TX Matrix and TX Matrix Plus routers only) (Optional) Display
statistics for a Flexible PIC Concentrator (FPC) slot. - On a TX Matrix router, if you specify the number of a
T640 router 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.
- On a TX Matrix Plus router, if you specify the number
of a T1600 router 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
- On a TX Matrix Plus router in the TXP-T1600-3D, TXP-T4000-3D,
or TXP-Mixed-LCC-3D configuration, if you specify the number of a
T1600 or T4000 router 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 63.
For example, the following commands have the same result: user@host> show pfe statistics ip fpc 1 lcc 1 user@host> show pfe statistics ip fpc 9 |
icmp | — | (Optional) Display
Packet Forwarding Engine IP ICMP statistics. |
lcc number | — | (TX Matrix and TX Matrix Plus routers only) (Optional)
On a TX Matrix router, display error statistics for a specific T640
router (or line-card chassis) that is connected to a TX Matrix router.
On a TX Matrix Plus router, display error statistics for a specified
router (or line-card chassis) that is connected to a TX Matrix Plus
router. Replace number with the following
values depending on the LCC configuration: - 0 through 3, when T640 routers are connected to a TX Matrix
router in a routing matrix.
- 0 through 3, when T1600 routers are connected to a TX
Matrix Plus router in a routing matrix.
- 0 through 7, when T1600 routers are connected to a TX
Matrix Plus router with 3D SIBs in a routing matrix.
- 0, 2, 4, or 6, when T4000 routers are connected to a TX
Matrix Plus router with 3D SIBs in a routing matrix.

Display Packet Forwarding Engine IP options statistics.  | Note:
On M and T series routers, firewall filters cannot count ip-options packets on a per option type and per interface basis.
A limited work around for this limitation is to use this show pfe statistics ip options command. |

List of Sample Output

Table 1 lists the output fields for the show pfe statistics ip command. Output fields are listed in the approximate order in which
they appear.
Table 1: show pfe statistics ip Output Fields
Field Name | Field Description |
|---|
ICMP Statistics | ICMP 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
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.
- 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.
|
ICMP errors | ICMP 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.
|
ICMP Discards | ICMP 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.
