Release Information

Command introduced before Junos OS Release 7.4.

Description

Display Packet Forwarding Engine direct memory access (DMA) statistics.

Options

none—Display all Packet Forwarding Engine direct memory access 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:

content_copy zoom_out_map
user@host> show pfe statistics dma fpc 1 lcc
1
user@host> show pfe statistics dma 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 a TX Matrix router. On a TX Matrix Plus router, display statistics for a specific router (or line-card chassis) that is connected to a TX Matrix 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.
