OUTPUT

71   LG-ID
72       ID of the link group.
73
74   LG-Role
75       Role of the link group.
76
77       SERV   The link group has a SERVER role.
78
79       CLNT   The link group has a CLIENT role.
80
81   LG-Type
82       Type of the link group.
83
84       NONE   The link group has the initial type.
85
86       SINGLE The link group has only a single link, i.e.  the local and the
87              peer system can offer one device port only for this link group,
88              which means a link outage on either side cannot be recovered.
89
90       SYM    The link group has two symmetric links, i.e.  the local and the
91              peer system can offer two device ports for this link group,
92              which means a link outage on either side can be recovered.
93
94       ASYMP  The link group has asymmetric links, i.e.  the peer system can
95              offer one device port only for this link group, which means a
96              link outage on the peer side cannot be recovered.
97
98       ASYML  The link group has asymmetric links, i.e.  the local system can
99              offer one device port only for this link group, which means a
100              link outage on the local side cannot be recovered.
101
102   VLAN
103       The VLAN to which the link group belongs.
104
105   #Conns
106       Number of connections(sockets) running on the link or link group.
107
108   PNET-ID
109       PNET ID of the link group. Asterisk "*" means PNET ID is set by the
110       user.
111
112   Net-Dev
113       Network device name corresponding to the link.
114
115   Link-State
116       The state of the link.
117
118       LINK_UNUSED
119              The link is not in use and in initial state.
120
121       LINK_INACTIVE
122              The link is inactive and will go away.
123
124       LINK_ACTIVATING

126
127       LINK_ACTIVE
128              The link is active and operates on an established link with the
129              peer.  Data is being exchanged via RDMA.
130
131   Link-UID
132       Unique identifier of the link. This identifier consists of link group
133       id and link id.
134
135   Peer-UID
136       Unique identifier of the link on the peer side. This identifier con‐
137       sists of link group id and link id.
138
139   IB-Dev
140       Name of the RoCE device used by the link.
141
142   IB-P
143       Port of the RoCE device used by the link.
144
145   Local-GID
146       GID of the RoCE port used by the link.
