ESRP Tracking
Tracking information is used to track various forms of connectivity from the ESRP switch to the outside
world. This section describes the following ESRP tracking options:
• ESRP Environment Tracking on page 239
• ESRP VLAN Tracking on page 239
• ESRP Route Table Tracking on page 240
• ESRP Ping Tracking on page 240
• Displaying Tracking Information on page 240
ESRP Environment Tracking
You can configure ESRP to track hardware status. If a power supply fails, if the chassis is overheating,
or if a non-fully loaded power supply is detected, the priority for the ESRP domain will change to the
failover settings.
NOTE
ExtremeWare XOS determines the maximum available power required for the BlackDiamond 10808
switch by calculating the number of power supplies and the power required by the installed modules.
Enabling environmental tracking on a BlackDiamond 10808 switch without enough power budget causes
tracking to fail. In this case, the tracking failure occurs by design.
To configure the failover priority for an ESRP domain, follow these steps:
1 Set the failover priority, using the following command:
configure esrp <esrpDomain> add track-environment failover <priority>
2 Assign the priority flag precedence over the active ports count, using the following command:
configure esrp <esrpDomain> election-policy [ports > track > priority | ports >
track > priority > mac | priority > mac | priority > ports > track > mac |
priority > track > ports > mac | sticky > ports > track > priority | sticky >
ports > track > priority > mac | sticky > ports > track > priority > mac >
weight | sticky > priority > mac | sticky > priority > ports > track > mac |
sticky > priority > track > ports > mac | sticky > track > ports > priority > |
sticky > track > ports > priority > mac
Because the priority of both ESRP domains are set to the same value, ESRP will use the active ports
count to determine the master ESRP domain.
ESRP VLAN Tracking
You can configure an ESRP domain to track port connectivity to a specified VLAN as criteria for ESRP
failover. The number of VLAN active ports are tracked. If the switch is no longer connected to the
specified VLAN, the switch automatically relinquishes master status and remains in slave mode. You
can track a maximum of one VLAN.
To add or delete the tracked VLAN, use one of the following commands:
configure esrp <esrpDomain> add track-vlan <vlan_name>>
configure esrp <esrpDomain> delete track-vlan <vlan_name>
