show system statistics tcp
语法
show system statistics tcp
语法(EX 系列交换机)
show system statistics tcp <all-members> <local> <member member-id>
语法(TX 矩阵路由器)
show system statistics tcp <all-chassis | all-lcc | lcc number | scc>
语法(TX Matrix Plus 路由器)
show system statistics tcp <all-chassis | all-lcc | lcc number | sfc number>
描述
显示系统范围的传输控制协议 (TCP) 统计信息。
选项
none | 显示 TCP 的系统统计信息。 |
all-chassis | (可选)显示机箱中所有路由器的 TCP 系统统计信息。 |
all-lcc | (可选)在 TX 矩阵路由器上,显示连接到 TX 矩阵路由器的所有 T640 路由器的 TCP 系统统计信息。在 TX Matrix Plus 路由器上,显示所有连接的 T1600 或 T4000 LCC 的 TCP 系统统计信息。 |
all-members | (可选)显示虚拟机箱配置的所有成员的 TCP 统计信息。 |
lcc number | (可选)在 TX 矩阵路由器上,显示连接到 TX 矩阵路由器的特定 T640 路由器的 TCP 系统统计信息。在 TX Matrix Plus 路由器上,显示连接到 TX Matrix Plus 路由器的特定路由器的 TCP 系统统计信息。 根据 number LCC 配置替换为以下值:
|
local | (可选)显示本地虚拟机箱成员的 TCP 统计信息。 |
member member-id | (可选)显示虚拟机箱配置的指定成员的 TCP 统计信息。替换为 member-id 0 到 9 之间的值。 |
scc | (可选)显示 TX Matrix 路由器(或交换卡机箱)的 TCP 系统统计信息。 |
sfc number | (可选)显示 TX Matrix Plus 路由器的 TCP 系统统计信息。替换为 number 0。 |
其他信息
默认情况下,在 TX Matrix 路由器或 TX Matrix Plus 路由器的主路由引擎上发出 show system statistics tcp
命令时,该命令将广播到路由矩阵中与其连接的 LCC 的所有主路由引擎。同样,如果在 TX Matrix 或 TX Matrix Plus 路由器的备份路由引擎上发出相同的命令,则该命令将广播到路由矩阵中与其连接的 LCC 的所有备份路由引擎。
