• <Partition Properties>:
[<Port list>|<MCast Group>]* | <Port list>
• <Port List>:
<Port Specifier>[,<Port Specifier>]
• <Port Specifier>:
<PortGUID>[=[full|limited|both]]
where
PortGUID
GUID of partition member EndPort. Hexadecimal numbers should
start from 0x, decimal numbers are accepted too.
full, limited
Indicates full and/or limited membership for this both port.
When omitted (or unrecognized) limited membership is assumed.
Both indicates both full and limited membership for this
port.
• <MCast Group>:
mgid=gid[,mgroup_flag]*<newline>
where
mgid=gid gid specified is verified to be a Multicast address IP groups are ver-
ified to match the rate and mtu of the broadcast group. The P_Key bits
of the mgid for IP groups are verified to either match the P_Key spec-
ified in by "Partition Definition" or if they are 0x0000 the P_Key
will be copied into those bits.
mgroup_flag rate=<val> Specifies rate for this MC group (default
is 3 (10GBps))
mtu=<val> Specifies MTU for this MC group (default is
4 (2048))
sl=<val> Specifies SL for this MC group (default is
0)
scope=<val> Specifies scope for this MC group (default
is 2 (link local)). Multiple scope settings
are permitted for a partition.
NOTE: This overwrites the scope nibble of
the specified mgid. Furthermore specifying
multiple scope settings will result in mul-
tiple MC groups being created.
qkey=<val> Specifies the Q_Key for this MC group
(default: 0x0b1b for IP groups, 0 for other
groups)
tclass=<val> Specifies tclass for this MC group (default
is 0)
FlowLabel=<val> Specifies FlowLabel for this MC group
(default is 0)
Note that values for rate, MTU, and scope should be specified as defined in the IBTA specifica-
tion (for example, mtu=4 for 2048). To use 4K MTU, edit that entry to
"mtu=5" (5 indicates 4K
MTU to that specific partition).
