Table 48 describes the ESRP election algorithms. Each algorithm considers the election factors in a
different order of precedence. The election algorithms that use sticky and weight are only available in
extended mode.

CAUTION
All switches in the ESRP network must use the same election algorithm, otherwise loss of connectivity, broadcast
storms, or other unpredictable behavior may occur.

Description
Specifies that this ESRP domain should consider election factors in
the following order: Active ports, tracking information, ESRP priority.
Specifies that this ESRP domain should consider election factors in
the following order: Active ports, tracking information, ESRP priority,
MAC address. This is the default election algorithm for standard
mode.
Specifies that this ESRP domain should consider election factors in
the following order: ESRP priority, MAC address.
Specifies that this ESRP domain should consider election factors in
the following order: ESRP priority, active ports, tracking information,
MAC address.
Specifies that this ESRP domain should consider election factors in
the following order: ESRP priority, tracking information, active ports,
MAC address.
Specifies that this ESRP domain should consider election factors in
the following order: Stickiness, active ports, tracking information,
ESRP priority.
Specifies that this ESRP domain should consider election factors in
the following order: Stickiness, active ports, tracking information,
ESRP priority, MAC address.
Specifies that this ESRP domain should consider election factors in
the following order: Stickiness, active ports, port weight, tracking
information, ESRP priority, MAC address. Beginning with ExtremeWare
XOS 11.1 and later, this is the default election algorithm for extended
mode.

the following order: Stickiness, ESRP priority, tracking information,
active ports, MAC address.
