clear esrp counters
ExtremeWare XOS 11.0 Command Reference Guide 539
clear esrp counters
clear esrp {<esrpDomain>} counters
Description
Clears the statistics gathered by ESRP for one or all ESRP domains on the switch.
Syntax Description
Default
None.
Usage Guidelines
Use this command to clear the state transition and the protocol packet counters gathered by ESRP.
The state transition count displays the number of times the ESRP domain entered the following states:
• Aware—An Extreme switch that does not participate in ESRP elections but is capable of listening to
ESRP Bridge Protocol Data Units (BPDUs).
• Master—The master switch is the device with the highest priority based on the election algorithm.
The master is responsible for responding to clients for Layer 3 routing and Layer 2 switching for the
ESRP domain.
• Neutral—The neutral state is the initial state entered by the switch. In a neutral state, the switch
waits for ESRP to initialize and run. A neutral switch does not participate in ESRP elections.
• PreMaster—The pre-master state is an ESRP switch that is ready to be master.
• Slave—The slave switch participates in ESRP but is not elected or configured the master and does
not respond to ARP requests but does exchange ESRP packets with other switches on the same
VLAN.
The slave switch is available to assume the responsibilities of the master switch if the master
becomes unavailable or criteria for ESRP changes.
If the slave is in extended mode, it does not send ESRP hello messages; however, it sends PDUs that
may trigger a change in the master switch.
For more information about configuring the ESRP mode of operation on the switch, see the
configure esrp mode [extended | standard]
command. By default, ESRP operates in extended
mode.
To display information about the ESRP domain, including the previously described states, use the
show
esrp {<name>}
command.
The protocol packet count displays the number of times ESRP, ESRP-aware, and ESRP error packets
were transmitted and received.
To display information about the ESRP counters, use the
show esrp {<name>} counters
command.
esrpDomain Specifies the name of an ESRP domain.
