Viewing ESRP Detail Information
You can display detailed ESRP information for the switches in an individual ESRP-enabled VLAN by
clicking on the VLAN name in the Component Tree in the left-hand panel of the window. This displays
a status window for the selected VLAN similar to the one shown in
Figure 168 .
Election Algorithm The ESRP election algorithm in use for this VLAN. The election algorithm determines
the order of precedence of the election factors used to determine the ESRP Master. The
election factors are:
• Ports : The number of active ports (the switch with the highest number takes priority)
• Track : Whether the switch is using ESRP tracking (a switch using tracking has
priority)
• Priority : A user-defined priority number between 0 and 254 (a higher number has
higher priority)
• MAC : The switch MAC address (a higher-number address has priority)
The election algorithm can be one of the following:
•
ports_track_priority_mac
(the default): This algorithm considers active ports
first, then tracking, then priority, then the MAC address to determine the ESRP
Master. This is the only algorithm supported for ExtremeWare releases prior to
version 6.0
•
track_ports_priority_mac
•
priority_ports_track_mac
•
priority_track_ports_mac
•
priority_mac_only
: only considers priority and the MAC address
See the ExtremeWare Software User Guide , version 6.1 or later, for details.
NOTE
Note that the ESRP election algorithm must be identical on all switches in an ESRP
group. If it is not, serious problems may arise.
Hello Timer This is the interval, in seconds, for exchanging keep-alive packets between the ESRP
switches for this ESRP-enabled VLAN. Also known as the ESRP timer. The default is 2
seconds.
