NAME <\/a> <\/h2>\n

rdma-dev \u2212 RDMA device configuration<\/p>\n

SYNOPSIS <\/a> <\/h2>\n

rdma<\/b> [ OPTIONS<\/i> ] dev<\/b> { COMMAND<\/i> | help<\/b> }<\/p>\n

OPTIONS<\/i> := { \u2212V<\/b>[ersion<\/i>] | \u2212d<\/b>[etails<\/i>] }<\/p>\n

rdma dev show<\/b> [ DEV<\/i> ]<\/p>\n

rdma dev set<\/b> [ DEV<\/i> ] name NEWNAME<\/b><\/p>\n

rdma dev set<\/b> [ DEV<\/i> ] netns NSNAME<\/b><\/p>\n

rdma dev set<\/b> [ DEV<\/i> ] adaptive-moderation [on\/off]<\/b><\/p>\n

rdma dev help<\/b><\/p>\n

DESCRIPTION <\/a> <\/h2>\n

rdma dev set – rename RDMA device or set network namespace or set RDMA device adaptive-moderation
rdma dev show – display RDMA device attributes<\/b>
DEV<\/i> – specifies the RDMA device to show. If this argument is omitted all devices are listed.<\/p>\n

EXAMPLES <\/a> <\/h2>\n

rdma dev<\/p>\n

Shows the state of all RDMA devices on the system.<\/p>\n

rdma dev show mlx5_3<\/p>\n

Shows the state of specified RDMA device.<\/p>\n

rdma dev set mlx5_3 name rdma_0<\/p>\n

Renames the mlx5_3 device to rdma_0.<\/p>\n

rdma dev set mlx5_3 netns foo<\/p>\n

Changes the network namespace of RDMA device to foo where foo is previously created using iproute2 ip command.<\/p>\n

rdma dev set mlx5_3 adaptive-moderation [on\/off]<\/p>\n

Sets the state of adaptive interrupt moderation for the RDMA device.
This is a global setting for the RDMA device but the value is printed for each CQ individually because the state is constant from CQ allocation.<\/p>\n
