Allied Telesis AT-8700XL, RAPIER I, X900-48FE Ethernet Protection Switching Ring Epsr Show epsr

Ethernet Protection Switching Ring (EPSR)		show epsr	29
	Table 1-2: Parameters displayed in the output of the show epsr command
	Parameter	Meaning
	Name	The name of the EPSR instance.
	Mode	Whether the EPSR instance is running as a Master or Transit node
		on this device.
	Status	The status of the named epsr instance: either Enabled or Disabled.
	State	The state of the EPSR instance.
		In a master node, a state can be: Idle, Complete or Failed.
		In the transit node, a state can be: Idle, Links-Up, Links-Down or
		Pre-Forwarding.
	Control VLAN	The control VLAN for the named EPSR instance. The VLAN
		Identifier is shown in brackets.
	Data VLAN(s)	A list of data VLANs for the named EPSR instance. The VLAN
		Identifiers are shown in brackets.
	Primary Port	The primary port for the named EPSR instance. This parameter is
		only shown on the master node for the instance named.
	Primary Port Status	The status of the primary port; either Unknown, Forwarding,
		Down or Blocking. Unknown is displayed when the EPSR instance
		is disabled. This parameter is only shown for a master node.
	Secondary Port	The secondary port for the EPSR instance. This parameter is only
		shown on the master node for the instance named.
	Secondary Port Status	The status of the secondary port; either Unknown, Forwarding,
		Down or Blocked. Unknown is displayed when the EPSR instance
		is disabled. This parameter is only shown for a master node.
	Hello Time	The rate that the TAPS protocol health control messages are
		transmitted from master node. It is specified in the create epsr
		command.
		The unit symbol following the value shows whether the time is
		measured in seconds or milliseconds.
	Failover Time	The time period that a master node waits for a healthcheck frame
		to circulate the loop before declaring that the EPSR ring has
		broken. The time period is measured from the time the frame
		leaves the master node’s primary port, to the time it is received at
		the master node’s secondary port. This parameter is only shown
		for a master node.
		The unit symbol following the value shows whether the time is
		measured in seconds or milliseconds.
	Ring Flap Time	The minimum number of seconds that a master node must remain
		in the failed state (before moving to the complete state), even if
		the ring has recovered from its fault condition. This delay is to limit
		unnecessary blocking and unblocking of the secondary port when
		a link in the ring is flapping. This parameter is only shown for a
		master node.
	Trap	Indicates whether SNMP traps will be sent when the EPSR instance
		changes state. The display is one of: enabled or disabled. If
		enabled, traps will be sent as long as the SNMP module is
		configured appropriately. If disabled, traps will not be sent.
	First Port	The first ring port for the EPSR instance. This parameter is only
		shown for an instance in transit mode.
