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 with 3D SIBs, if you specify the number of a T4000 router by using the lcc number option (the recommended method), replace slot with a value from 0 through 63. Otherwise, replace slot with a value from 0 through 31. For example, the following commands have the same result: user@host> show pfe statistics dma fpc 1 lcc 1user@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:
