DESCRIPTION
"Each entry contains information about one iFCP session consisting
of a pair of N_PORTs joined by a single TCP/IP connection. This
table’s INDEX includes ifcpLclGtwyInstIndex, which identifies the
local iFCP Gateway instance that created the session for the
entry.
Soon after an entry is created in this table for an iFCP session, it
will correspond to an entry in the tcpConnectionTable of the TCP-MIB
(RFC 4022). The corresponding entry might represent a preexisting
TCP connection, or it might be a newly-created entry. (Note that if
IPv4 is being used, an entry in RFC 2012’s tcpConnTable may also
correspond.) The values of ifcpSessionLclPrtlAddrType and
ifcpSessionRmtPrtlIfAddrType in this table and the values of
tcpConnectionLocalAddressType and tcpConnectionRemAddressType used
as INDEX values for the corresponding entry in the
tcpConnectionTable should be the same; this makes it simpler to
locate a session’s TCP connection in the TCP-MIB. (Of course, all
four values need to be ’ipv4’ if there’s a corresponding entry in
the tcpConnTable.)
If an entry is created in this table for a session, prior to
knowing which local and/or remote port numbers will be used for
the TCP connection, then ifcpSessionLclPrtlTcpPort and/or
ifcpSessionRmtPrtlTcpPort have the value zero until such time as
they can be updated to the port numbers (to be) used for the
connection. (Thus, a port value of zero should not be used to
locate a session’s TCP connection in the TCP-MIB.)
When the TCP connection terminates, the entry in the
tcpConnectionTable and the entry in this table both get deleted
(and, if applicable, so does the entry in the tcpConnTable)."

instance. This index is used because the local N Port and

"This is the interface index in the IF-MIB ifTable being used

in the ifTable, then the value is 0. The ifType of the
interface will generally be a type that supports IP, but an
implementation may support iFCP using other protocols. This
object can be used to obtain additional information about the
