NAMEIBADDR − query InfiniBand address(es)

SYNOPSISibaddr [options]

DESCRIPTIONDisplay the lid (and range) as well as the GID address of the port specified (by DR path, lid, or GUID) or the local port by default. Note: this utility can be used as simple address resolver.

OPTIONS−−gid_show, −g show gid address only −−lid_show, −l show lid range only −−Lid_show, −L show lid range (in decimal) only

Addressing Flags −D, −−Direct The address specified is a directed route Examples: [options] −D [options] "0" # self port [options] −D [options] "0,1,2,1,4" # out via port 1, then 2, ... (Note the second number in the path specified must match the port being used. This can be specified using the port selection flag '−P' or the port found through the automatic selection process.) −G, −−Guid The address specified is a Port GUID −s, −−sm_port <smlid> use 'smlid' as the target lid for SA queries.

Debugging flags −d  raise the IB debugging level. May be used several times (−ddd or −d −d −d). −e  show send and receive errors (timeouts and others) −h, −−help show the usage message −v, −−verbose  increase the application verbosity level. May be used several times (−vv or −v −v −v) −V, −−version show the version info.

Port Selection flags −C, −−Ca <ca_name> use the specified ca_name. −P, −−Port <ca_port> use the specified ca_port.

Local port SelectionMultiple port/Multiple CA support: when no IB device or port is specified (see the "local umad parameters" below), the libibumad library selects the port to use by the following criteria: 1. the first port that is ACTIVE. 2. if not found, the first port that is UP (physical link up). If a port and/or CA name is specified, the libibumad library attempts to fulfill the user request, and will fail if it is not possible. For example: ibaddr # use the first port (criteria #1 above) ibaddr −C mthca1 # pick the best port from "mthca1" only. ibaddr −P 2 # use the second (active/up) port from the first available IB device. ibaddr −C mthca0 −P 2 # use the specified port only.

Configuration flags −y, −−m_key <key>  use the specified M_key for requests. If non−numeric value (like 'x') is specified then a value will be prompted for. −t, −−timeout <timeout_ms> override the default timeout for the solicited mads. −−config, −z <config_file> Specify alternate config file. Default: /etc/infiniband-diags/ibdiag.conf

CONFIG FILE/etc/infiniband-diags/ibdiag.conf A global config file is provided to set some of the common options for all tools. See supplied config file for details.

EXAMPLES ibaddr # local port\'s address ibaddr 32 # show lid range and gid of lid 32 ibaddr −G 0x8f1040023 # same but using guid address ibaddr −l 32 # show lid range only ibaddr −L 32 # show decimal lid range only ibaddr −g 32 # show gid address only
