HP Auto Port Aggregation Administrator's Guide for HP-UX 11i v1 and 11i v2 September 2008

-t -x -t portPPA anyLinkAggregatePPA
Displays the current port priority for the port with the specified portPPA number. For
LACP_AUTO, this shows the priority value for the port. For HOT_STANDBY, this shows
which port is used for traffic and which for standby. This option is not applicable to
PAgP (FEC_AUTO).
-v -x -v linkAggregatePPA
Displays the status for a given link aggregate with the specified linkAggregatePPA
number. For example:
Link Aggregate PPA # : 901
Number of Ports : 3
Ports PPA : 2 1 3
Link Aggregation State : LINKAGG AUTO
Group Capability : 901
Load Balance Mode : MAC Address based (LB_MAC)
-y -x -y linkaggregatePPA
Displays the Hot Standby status for the link aggregate with the specified
linkAggregatePPA number.
vmtu [-x vmtu linkaggregatePPA]
Displays the TSO status for a given link aggregate with the specified linkAggregatePPA
number. For example:
# lanadmin -x vmtu 903
Driver/Hardware does not support TCP Segmentation Offload
#
# lanadmin -x vmtu 905
Driver/Hardware supports TCP Segmentation Offload, Current VMTU = 32160
#
The following option is supported, but with a different meaning:
-a
Displays the current station address of link aggregate with the specified
linkAggregatePPA number.
Invoking lanadmin from the Command Line
NOTE: Remember that the starting PPA number for link aggregates varies with the operating
system you have installed: for HP-UX 11.00, it is 100; and for 11i v1 and 11i v2, it is 900. The
following example uses HP-UX 11i.
• To obtain additional information on options for the lanadmin command, enter the following
command:
lanadmin -X -H linkAggregatePPA
Where linkAggregatePPA can be any valid link aggregate PPA value.
• To form a link aggregate of ports automatically using the Cisco Fast EtherChannel protocol
on that port, set the port configuration mode to FEC_AUTO. For example, if port 2 must be
trunked automatically, enter the following command:
lanadmin -X -p 2 FEC_AUTO 900
900 is the PPA of the first link aggregate. When the protocol completes successfully, HP
APA determines the link aggregate into which port 2 best fits and adds the port to an
aggregate based on the group_capability of ports and link aggregate. Ports in the same
link aggregate must be connected to the same host and in the same trunk.
• To form a link aggregate of ports automatically using the LACP protocol, use LACP_AUTO
in place of FEC_AUTO. In this case, key is used instead of group_capability.
