show pfe statistics traffic

Syntax

show pfe statistics traffic
<fpc slot>

Syntax (TX Matrix and TX Matrix Plus Router)

show pfe statistics traffic
<fpc slot>
< lcc number>

Release Information

Command introduced before JUNOS Release 7.4.

Description

Display Packet Forwarding Engine traffic statistics.

Options

none — Display statistics about PFE traffic. On the TX Matrix router, display statistics about PFE traffic for all its attached T640 routers. On the TX Matrix Plus router, display statistics about PFE traffic for all its attached T1600 routers

fpc slot — (T Series and M320 router 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. For example, the following commands have the same result:

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

lcc number — (TX Matrix and TX Matrix Plus routers only) (Optional) On a TX Matrix router, display statistics for a specific T640 router (or line-card chassis) that is connected to the TX Matrix router. On a TX Matrix Plus router, display statistics for a specific T1600 router (or line-card chassis) that is connected to the TX Matrix Plus router. Replace number with a value from 0 through 3.
