zpeer

NAME

zpeer – Application for High Availability communication between the Fabric and Data switches.

SYNOPSIS

zpeer [-d <level>] localpeer <command> <value>query zpeer [-d <level>][-a][-r]

DESCRIPTION

zpeer is used to pass bidirectional High Availability(HA) state and priority information between the base and fabric switches in the Ethernet Switch Blade. zpeer uses the concept of local and peer information. The local information is written, and the peer information is read. As an example:

On the base switch:

zpeer local priority 203

On the fabric switch the following command would return 203:

zpeer peer priority query

The communication is bidirectional so the example above can be reversed allowing the fabric switch to pass state and priority information to the base switch.

NOTE: Local information can also be read as confirmation and for debugging purposes.

zpeer is part of the HA software suite. It is called as part of the scripts that are generated by the zspconfig application. With the exception of querying information for debugging and validation, the zpeer application would not need to be executed by the user. Following is a quick overview of the values communicated between switches. See documentation on HA and zspconfig for better understanding of how zpeer fits in with the HA software suite.

Following is an example of setting the state to “backup”:

zpeer local state backup

 

Possible states are:

 

unhealthy

Set by hardware at power up or at system reboot. Set by

 

software when the HA software suite is stopped. Indicates that

 

the peer is not properly functioning

healthy

Set by software when HA is started. This state is never
