SYNOPSIS

       smcd [ OPTIONS ] linkgroup  { COMMAND | help }

       smcd linkgroup [ show ] [ all | LG-ID ]

       smcr [ OPTIONS ] linkgroup  { COMMAND | help }

       smcr linkgroup { show | link-show } [ all | LG-ID ] [ netdev NETDEV ] [ ibdev IBDEV ]

DESCRIPTION

       The smcd linkgroup command displays SMC-D link groups and their properties.  The smcr
       linkgroup command displays SMC-R link groups and links with their properties.

   smcd,smcr linkgroup show
       inspect the link group properties

       all (default)
              Show all link groups.

       LG-ID  Show the link group with the ID LG-ID

       netdev NETDEV
              SMC-R only: list the link groups for the specified network device.

       ibdev IBDEV
              SMC-R only: list the link groups for the specified RoCE device.

   smcr linkgroup link-show
       SMC-R only: Inspect the link properties

       all (default)
              List all links of all link groups.

       LG-ID  Show links of the link group with the id.  LG-ID

       netdev NETDEV
              List the links of the link groups for the specified network device.

       ibdev IBDEV
              List the links of the link groups for the specified RoCE device.

OUTPUT

   LG-ID
       ID of the link group.

   LG-Role
       Role of the link group.

       SERV   The link group has a SERVER role.

       CLNT   The link group has a CLIENT role.

   LG-Type
       Type of the link group.

       NONE   The link group has the initial type.

       SINGLE The link group has only a single link, i.e.  the local and the peer system can
              offer one device port only for this link group, which means a link outage on either
              side cannot be recovered.

       SYM    The link group has two symmetric links, i.e.  the local and the peer system can
              offer two device ports for this link group, which means a link outage on either
              side can be recovered.

       ASYMP  The link group has asymmetric links, i.e.  the peer system can offer one device
              port only for this link group, which means a link outage on the peer side cannot be
              recovered.

       ASYML  The link group has asymmetric links, i.e.  the local system can offer one device
              port only for this link group, which means a link outage on the local side cannot
              be recovered.

   VLAN
       The VLAN to which the link group belongs.

   #Conns
       Number of connections(sockets) running on the link or link group.

   PNET-ID
       PNET ID of the link group. Asterisk "*" means PNET ID is set by the user.

   Net-Dev
       Network device name corresponding to the link.

   Link-State
       The state of the link.

       LINK_UNUSED
              The link is not in use and in initial state.

       LINK_INACTIVE
              The link is inactive and will go away.

       LINK_ACTIVATING
              The link is being activated with the peer.

       LINK_ACTIVE
              The link is active and operates on an established link with the peer.  Data is
              being exchanged via RDMA.

   Link-UID
       Unique identifier of the link. This identifier consists of link group id and link id.

   Peer-UID
       Unique identifier of the link on the peer side. This identifier consists of link group id
       and link id.

   IB-Dev
       Name of the RoCE device used by the link.

   IB-P
       Port of the RoCE device used by the link.

   Local-GID
       GID of the RoCE port used by the link.

   Peer-GID
       GID of the peer RoCE port used by the link.

EXAMPLES

       1. Show all SMC-D link groups:
         # smcd linkgroup show all

       2. Show all SMC-D link groups with link group id 50:
         # smcd linkgroup show 50

       3. Show all SMC-R links:
         # smcr linkgroup link-show all

       4. Show all SMC-R links with link group ID 40:
         # smcr linkgroup link-show 40

       5. Show all SMC-R links on RoCE device "mlx4_0":
         # smcr linkgroup link-show ibdev mlx4_0

       6. Show all SMC-R links on network device "eth0":
         # smcr linkgroup link-show netdev eth0
