Got the request from client

The network failover configuration of the nlxa123 is no longer working as expected.
We noticed in our monitoring a continue swap of MAC address

What needs to be chcked here..

[SoorajCleris]

Hi Arun,
Which is the OS ?

Are you using APA?

Regards
Sooraj

[arun khatwani]

OS is HPUX 11.31

[arun khatwani]

Yes We r using APA

[sujit kumar singh]

hi,


is APA configired in failover mode?
can u post the following O/Ps , are you facing some network disconnectivities from the application side?



#lanscan

and for the lan900 , lan901 etc

#lanscan -x -v 900
#lanscan -x -v 901

#cat /etc/lanmon/lanconfig.ascii
also the files as /etc/rc.config.d/hp_apaconf
/etc/rc.config.d/hp_apaportconf
#lancheckconf

regards
sujit

[arun khatwani]

Sujit will post you reply tommorrow

but great how u know lan 900 and lan 901 are configured in our system.

#
# hp_apaconf : contains configuration values for HP Auto-Port Aggregation
# interfaces
#
# HP_APA_INTERFACE_NAME Name of Link Aggregation (lan900, lan901...)
#
# HP_APA_LOAD_BALANCE_MODE Defines the Load Balancing mode for the specified
# Link Aggregation (HP_APA_INTERFACE_NAME). The
# supported values are:
#
# LB_MAC - This algorithm uses a portion of the
# destination MAC address to determine
# how data flows are distributed across
# physical ports in a link aggregation.
#
# The recommended configuration for
# this algorithm is Server to Switch.
#
# LB_IP - This algorithm uses a portion of the
# destination IP address to determine
# how data flows are distributed across
# physical ports in a link aggregation.
#
# The recommended configuration for
# this algorithm is Server to Router.
# Note: At this point, Server-Router
# configuration is unsupported.
#
# LB_PORT - This algorithm uses the TCP or UDP
# port number to determine how data
# flows are distributed across
# physical ports in a link aggregation.
#
# The recommended configuration for
# this algorithm is Server to Server.
#
# LB_CPU - This algorithm uses the systems
# CPU's to determine how data flows
# are distributed across the physical
# ports in a link aggregation.
#
# The default value is LB_MAC.
#
# HP_APA_GROUP_CAPABILITY Sets the Group Capability of the linkagg.
# This controls which ports can join this link
# aggregate. Only ports which have the same group
# capability as the linkagg can join it.
#
# HP_APA_KEY Sets the Administrative Key of the linkagg.
# This controls which ports can join this link
# aggregate. Only ports which have the same key
# as the linkagg can join it.
#
# HP_APA_HOT_STANDBY Configure a link aggregation for hot standby mode.
# This parameter is mutually exclusive with the
# HP_APA_LOAD_BALANCE parameter. In addition, the
# HP_APA_HOT_STANDBY parameter takes precedence over
# HP_APA_LOAD_BALANCE parameter.
# Supported values are:
# on Turn on HOT-STANDBY-MODE on the link
# aggregation
# off Turn off HOT-STANDBY-MODE on the link
# aggregation
#
# The default value is off.
#
# HP_APA_MANUAL_LA Manually set ports for the specified link
# aggregation. The ports should be specified with
# PPA numbers. Each port should be separated by
# a ",".
#
# The parameters listed above can be obtained or set directly via the
# lanadmin(1M) command.
#
# HP_APA_MAX_LINKAGGS This parameter is used to change the number of APA
# LinkAggs for HP-UX 11.x systems. The valid value
# is from 5 to 50. The default value is 50.
#
# HP_APA_DEFAULT_PORT_MODE Set the default APA port configuration mode.
# Supported values are MANUAL, FEC_AUTO, LACP_AUTO
# and LAN_MONITOR.
# The default value is MANUAL.
#
# A port's mode WILL be set to the value of
# HP_APA_DEFAULT_PORT_MODE
# UNLESS its mode IS specified in the hp_apaportconf
# file using variable HP_APAPORT_CONFIG_MODE
# For example,
# case 1:
# the configuration mode of port 1 is NOT set in
# hp_apaportconf,
# HP_APA_DEFAULT_PORT_MODE is NOT set in hp_apaconf,
# then port 1 will be set to MANUAL.
# case 2:
# the configuration mode of port 1 is NOT set in
# hp_apaportconf,
# HP_APA_DEFAULT_PORT_MODE IS set to FEC_AUTO,
# then port 1 will be set to FEC_AUTO.
# case 3:
# the configuration mode of port 1 IS set to
# LACP_AUTO in hp_apaportconf,
# HP_APA_DEFAULT_PORT_MODE IS set to MANUAL,
# then port 1 will be set to LACP_AUTO.
#
# HP_APA_LACP_SYSTEM_ID_MODE Tells APA How to set the LACP System ID. The
# values are:
#
# FIRST_APA_PORT:
# Set the LACP System ID to the first APA supported
# port.
# FIRST_LACP_PORT: Set the LACP System ID to the
# first up port that starts LACP.
#
# The default is FIRST_APA_PORT.
#
#
# HP_APA_USE_SYSLOG This is used to set the logging of selected
# APA/LM messages into syslog.log file.
# Possible values and its meaning are:
# 0 : Do not log messages into syslog.log file.
# 1 : Log selected messages into syslog.log file.
# Default value is 0. If this variable is not set
# in this file or has wrong value, then the default
# value is used.
#
# HP_APA_LACP_TIMEOUT This variable is used to control LACP timeout
# value. Possible values and its meaning are:
# 0 : Use long LACP timeout. (Default)
# 1 : Use short LACP timeout.
# Default value is 0. If this variable is not set
# in this file or has wrong value, then the default
# value is used.
#
# The following examples illustrate how to use the parameters defined
# above.
#
# HP_APA_MAX_LINKAGGS=25
# HP_APA_DEFAULT_PORT_MODE=MANUAL
# HP_APA_LACP_SYSTEM_ID_MODE=FIRST_APA_PORT
# HP_APA_USE_SYSLOG=1

# hp_apaportconf : contains configuration values for Physical Ports for
# HP Auto-Port Aggregation interfaces
#
# HP_APAPORT_INTERFACE_NAME Name of physical interface (lan0, lan1...)
#
# HP_APAPORT_GROUP_CAPABILITY Set the group capability for the port specified
# by HP_APAPORT_INTERFACE_NAME. The group
# capability controls which link aggregations the
# specified port can be grouped with.
#
# The default group capability is 5.
#
# HP_APAPORT_KEY Set the administrative key for the port specified
# by HP_APAPORT_INTERFACE_NAME. The key controls
# which link aggregations the specified port can
# be grouped with.
#
# The default administrative key is 0.
#
# HP_APAPORT_PRIORITY Set the port priority for the port specified by
# HP_APAPORT_INTERFACE_NAME. The port priority
# determines which port in a link aggregation
# will be the primary interface when the link
# aggregation is set to hot standby mode
# (HP_APA_HOT_STANDBY="on").
#
# The default port priority is 0.
#
# HP_APAPORT_CONFIG_MODE Set the configuration mode for physical port
# specified by HP_APAPORT_INTERFACE_NAME. The
# supported values are listed below:
#
# FEC_AUTO The Cisco Fast EtherChannel (FEC)
# Port Aggregation Protocol (PAgP)
# should be started on the port.
#
# This is the default configuration
# mode for all ports which support
# the HP APA product.
#
# MANUAL Both PAgP and LACP will be disabled
# on the port and it must therefore be
# manually added or removed from a
# specific link aggregation.
#
# LACP_AUTO The IEEE 802.3ad Link Aggregation
# Control Protocol (LACP)
# should be started on the port.
#
# LAN_MONITOR Both PAgP and LACP will be disabled
# on the port and it must therefore be
# manually added or removed from a
# specific link aggregation using
# lanapplyconf landeleteconf commands.
#
# The default config mode is the same as the value
# of HP_APA_DEFAULT_CONFIG_MODE whose default is
# MANUAL.
#
# HP_APAPORT_SYSTEM_PRIORITY Set the port system priority for the port
# specified by HP_APAPORT_INTERFACE_NAME.
# The system priority gives control to the system
# to resolve waiting ports to be added in a linkagg
#
# The default system priority is 0.
#
#
