L2 Failover with Other Features
L2
Failover
works
together
with
Link
Aggregation
Control
Protocol
(LACP)
and
with
Spanning
Tree
Protocol
(STP),
as
described
in
the
next
sections.
LACP
Link
Aggregation
Control
Protocol
allows
the
switch
to
form
dynamic
LAGs.
You
can
use
the
admin
key
to
add
up
to
two
LACP
LAGs
to
a
failover
trigger
using
automatic
monitoring.
When
you
add
an
admin
key
to
a
trigger,
any
LACP
LAG
with
that
admin
key
becomes
a
member
of
the
trigger.
Note:
If
you
change
the
LACP
system
priority
on
an
LACP
aggregation,
the
failover
trigger
goes
down.
Spanning Tree Protocol
If
Spanning
Tree
Protocol
(STP)
is
enabled
on
the
ports
in
a
failover
trigger,
the
switch
monitors
the
port
STP
state
rather
than
the
link
state.
A
port
failure
results
when
STP
is
not
in
a
Forwarding
state
(such
as
Learning
,
Discarding
or
No
Link
).
The
switch
automatically
disables
the
appropriate
internal
ports,
based
on
the
VLAN
monitor.
When
the
switch
determines
that
ports
in
the
trigger
are
in
STP
Forwarding
state,
then
it
automatically
enables
the
appropriate
internal
ports,
based
on
the
VLAN
monitor.
The
switch
fails
back
to
normal
operation
.
