- show system statistics tcp
- show system statistics tcp
- <all-lcc | lcc number | scc>
Command introduced before JUNOS Release 7.4.
Display system-wide Transmission Control Protocol (TCP) statistics.
all-lcc — (Routing matrix only) (Optional) Display system statistics for TCP for all T640 routing nodes (or line-card chassis) connected to a TX Matrix platform.
lcc number — (Routing matrix only) (Optional) Display system statistics for TCP for a specified T640 routing node (or line-card chassis) connected to a TX Matrix platform. Replace number with a value from 0 through 3.
scc — (Routing matrix only) (Optional) Display system statistics for TCP for the TX Matrix platform (or switch-card chassis).
By default, when you issue the show system statistics tcp command on a TX Matrix master Routing Engine, the command is broadcast to all the T640 master Routing Engines connected to it. Likewise, if you issue the same command on the TX Matrix backup Routing Engine, the command is broadcast to all the T640 backup Routing Engines that are connected to it.
