Description
Configures the election algorithm on the switch.
Syntax Description
Default
ports_track_priority_mac
election algorithm.
Usage Guidelines
The election algorithm determines the order of precedence of the election factors used to determine the
ESRP Master. The election factors are:
• Active Ports (
ports
): the number of active ports (the switch with the highest number takes priority)
• Tracking Information (
track
): whether the switch is using ESRP tracking. A switch using tracking
has priority.
• ESRP Priority (
priority
): a user-defined priority number between 0 and 254. A higher number has
higher priority. The default priority setting is 0. A priority setting of 255 makes an ESRP switch
remain in slave mode and is the recommended setting for system maintenance. A switch with a
priority setting of 255 will never become the master.
• MAC address (
mac
): the switch MAC address. A higher-number address has priority.
The election algorithm must be the same on all switches for a particular VLAN.
vlan name Specifies a VLAN name.
ports-track-priority Specifies that this VLAN should consider election factors in the following
order: Active ports, tracking information, ESRP priority.
ports-track-priority-mac Specifies that this VLAN should consider election factors in the following
order: Active ports, tracking information, ESRP priority, MAC address. This is
the default election algorithm.
track-ports-priority Specifies that this VLAN should consider election factors in the following
order: Tracking information, active ports, ESRP priority.
track-ports-priority-mac Specifies that this VLAN should consider election factors in the following
order: Tracking information, active ports, ESRP priority, MAC address.
priority-ports-track-mac Specifies that this VLAN should consider election factors in the following
order: ESRP priority, active ports, tracking information, MAC address.
priority-track-ports-mac Specifies that this VLAN should consider election factors in the following
order: ESRP priority, tracking information, active ports, MAC address.
priority-mac-only Specifies that this VLAN should consider election factors in the following
order: ESRP priority, MAC address.
