5.16.7 EAPS protocol
EAPS (Ethernet Automatic Protection Switching) protocol allows to increase stability and robustness
of data network with ring topology by decreasing the restoration time after the failure. Restoration time
does not exceed 1 second, that is substantially lower than the network reconstruction in case of spanning
tree family protocols.
Global configuration mode commands
Command line request in global configuration mode appears as follows:
console(config)#
Table 5.92 —Global configuration mode commands
Enable EAPS protocol operation.
Disable EAPS protocol operation.
Define the absence time for test packets, that should pass for
ring failure to be registered.
Set the timer default value.
Hello-packet sending frequency timer.
Set the timer default value.
Create EAPS region with domain-id identifier and enter the
region configuration mode.
Remove EAPS region with domain-id identifier.
Domain configuration mode commands
Command line request in domain configuration mode appears as follows:
console(config-eaps-domain)#
Table 5.93 —EAPS domain configuration mode commands
Identifier of VLAN being used for EAPS management. Also, the
next successive VLAN identifier is used for secondary loop
management. Master EAPS VLAN should not be used for
transmission of other traffic types.
