Problem
The Intelligent Networking Pack
license is installed but I cannot
enable Active Path Failover on the
team. It is grayed out.
The Intelligent Networking Pack
license is installed but I cannot
enable Fast Path Failover on the
team. It is grayed out.
One or more members (but not all)
of the team currently have a red X
with a status of "Active Path
Failure" and the team is degraded
(yellow team icon).
The Active Path Mechanism is
enabled and all adapters in the
team show a yellow X with a status
of "Active Path Failure," however
I can successfully ping the Echo
Node device.
All members in the team show a
yellow X with a status of "Fast Path
Failure," however the adapters are
operating successfully.
When using the Fast Path
mechanism with VLANS and
PVST+, my adapters all show a
yellow X with a status of "Fast Path
Failure," however the adapters are
operating successfully.
Possible Cause
This may be expected behavior based
on the configured settings.
This may be expected behavior based
on the configured settings.
Active Path Failure is a failure
condition of the Active Path Failover
mechanism. If one or more members
(but not all) of the team have a red X
with a status of "Active Path Failure,"
this means those members did not
receive a response from the Echo
Node device during the last interval.
If using the Directed ARP method
and the Echo Node device is a router
or a Linux server, this is expected
behavior.
The Spanning Tree Protocol may be
disabled on the switches or the wrong
protocol may be selected on the
Advanced Redundancy Tab of the
team.
The Native VLAN of the switch may
not match what is configured on the
VLAN Tab of the team in the
Default/Native VLAN box.
Possible Solution
Open the Network Configuration Utility
(NCU) and check to see if the team
contains a 10/100 network adapter
(NC31xx series).
If so, remove the NC31xx series and
apply changes before attempting to
enable Active Path Failover. The NC31xx
10/100 adapters do not support the Active
Path Failover mechanism.
Open the Network Configuration Utility
(NCU) and go to the Information tab for
the team. Check the Current Mode.
If the current team mode is 802.3ad
Dynamic with Fault Tolerance or SLB
(Switch-assisted Load Balancing, this is
normal behavior. These team modes do
not support Fast Path Failover.
First, ensure that there are no split LAN
conditions possibly caused by an
upstream link failure to the core network.
Second, if there are no split LAN
conditions, go to the Advanced
Redundancy tab for the team. Set the
timers under Active Path Failover to a
greater value. Possibly the timers are set
too low for the network environment.
Try doubling the current timers and
retest with these settings.
Change the Active Path Mechanism to
Community Address ARP. This newer
method works with all devices as the
Echo Node. It requires an additional IP
address for the Community ARP;
however all servers on the network using
this feature can use this address.
Ensure the Spanning Tree Protocol is
running on the switches in the network.
Ensure the protocol selected on the
Advanced Redundancy Tab is the same
protocol running on the switches in the
network. Only PVST+ and 802.1D are
supported.
Ensure the Native VLAN of the switch
is the same as the Default/Native VLAN
configured in the NCU on the VLAN Tab
of the team.
For example if the Native VLAN on the
ports you are connected to is VLAN 20,
then ensure the VLAN Tab of the team
is configured for VLAN 20 on the
Default//Native VLAN box.
