Ethernet Automatic Protection Switching
State: On a transit node, the command displays one of the following states:
• Idle—The EAPS domain has been enabled, but the configuration is
not complete.
• Links-Up—This EAPS domain is running, and both its ports are up
and in the FORWARDING state.
• Links-Down—This EAPS domain is running, but one or both of its
ports are down.
• Preforwarding—This EAPS domain is running, and both of its ports
are up, but one of them is in a temporary BLOCKED state.
On a master node, the command displays one of the following states:
• Idle—The EAPS domain has been enabled, but the configuration is
not complete.
• Init—The EAPS domain has started but has not yet determined the
status of the ring. The secondary port is in a BLOCKED state.
• Complete—The ring is in the COMPLETE state for this EAPS
domain.
• Failed—There is a break in the ring for this EAPS domain.
• [Failtimer Expired]—When the failtimer expires and it’s action is set
to send-alert, this flag is set. This flag indicates there is a
misconfiguration or hardware problem in the EAPS ring. The EAPS
master node will continue to remain in COMPLETE or INIT state
with it’s secondary port blocking.
[Running: …] • Yes—This EAPS domain is running.
• No—This EAPS domain is not running.
Enabled: Indicates whether EAPS is enabled on this domain.
• Y—EAPS is enabled on this domain.
• N—EAPS is not enabled.
Mode: The configured EAPS mode for this switch: transit (T) or master (M).
Primary/Secondary port: The port numbers assigned as the EAPS primary and secondary ports.
On the master node, the port distinction indicates which port is blocked
to avoid a loop.
Port status: • Unknown—This EAPS domain is not running, so the port status has
not yet been determined.
• Up—The port is up and is forwarding data.
• Down—The port is down.
• Blocked—The port is up, but data is blocked from being forwarded.
Tag status: Tagged status of the control VLAN:
• Tagged—The control VLAN has this port assigned to it, and the port
is tagged in the VLAN.
• Untagged—The control VLAN has this port assigned to it, but the
port is untagged in the control VLAN.
• Undetermined—Either a VLAN has not been added as the control
VLAN to this EAPS domain or this port has not been added to the
control VLAN.
Hello Timer interval: The configured value of the timer in seconds, specifying the time that
the master node waits between transmissions of health-check packets.
