show eaps counters

show eaps counters [eapsDomain | global]

Description

Displays summary EAPS (Extreme Automatic Protection Switching) counter information.

Syntax Description

eapsDomain Specifies the name of an EAPS domain. The switch displays counter information for only that domain.
global Displays EAPS counter information when the events counted are not applicable to any specific EAPS domain.

Default

N/A.

Usage Guidelines

If you specify the name of an EAPS domain, the switch displays counter information related to only that domain. If you specify the global keyword, the switch displays EAPS counter information when the events counted are not applicable to any specific EAPS domain. The output displayed is for all configured EAPS domains, not just one specific EAPS domain.

Viewing and maintaining statistics on a regular basis allows you to see how well your network is performing. If you keep simple daily records, you will see trends emerging and notice problems arising before they cause major network faults.

Clearing the Counters

The counters continue to increment until you clear the information. By clearing the counters, you can see fresh statistics for the time period you are monitoring. To clear, reset the EAPS counters, use one of the following commands:

Understanding the Output

The following table describes the significant fields and values in the display output of the show eaps counters eapsDomain command:
Field Description

Rx-Health

Indicates the EAPS domain received EAPS Health PDUs.

Rx-RingUp-FlushFdb

Indicates the EAPS ring is up, and the EAPS domain received EAPS RingUp-FlushFdb PDUs to flush the FDB (forwarding database).

Rx-RingDown-FlushFdb

Indicates the EAPS ring is down, and the EAPS domain received EAPS RingDown-FlushFdb PDUs to flush the FDB.

Rx-Link-Down

Indicates the EAPS domain received EAPS Link-Down PDUs and took down the link.

Rx-Flush-Fdb

Indicates the EAPS domain received EAPS Flush-Fdb PDUs and flushed the FDB.

Rx-Suspend-Prefwd-Timer

Indicates the EAPS domain received EAPS Suspend-Preforward-Timer PDUs.

Rx-Query-Link-Status

Indicates the EAPS domain received EAPS Query-Link-Status PDUs.

Rx-Link-Up

Indicates the EAPS domain received EAPS Link-Up PDUs and brought the link back up.

Rx-Unknown

Indicates the EAPS domain dropped unknown EAPS PDUs.

Rx-Another-Master

Indicates the EAPS domain dropped EAPS PDUs because there is another Master switch in the same EAPS domain.

Rx-Unconfigured-Port

Indicates the EAPS domain dropped EAPS PDUs because the ingress port is not configured to be a ring port for the EAPS domain and the corresponding control VLAN (Virtual LAN).

Rx-Health-Pdu-Pri-Port

Indicates the EAPS domain dropped EAPS Health PDUs because the primary port received them instead of the secondary port.

NOTE: The secondary port of the Master switch must receive EAPS Health PDUs, not the primary port.

Tx-Health

Indicates the EAPS domain sent EAPS Health PDUs.

Tx-RingUp-FlushFdb

Indicates the EAPS ring is up, and the EAPS domain sent EAPS RingUp-FlushFdb PDUs to flush the FDB.

Tx-RingDown-FlushFdb

Indicates the EAPS ring is down, and the EAPS domain sent EAPS RingDown-FlushFdb PDUs to flush the FDB.

Tx-Link-Down

Indicates the EAPS domain sent EAPS Link-Down PDUs because the link went down.

Tx-Flush-Fdb

Indicates the EAPS domain sent EAPS Flush-Fdb PDUs because the FDB needs to be flushed.

Tx-Suspend-Prefwd-Timer

Indicates the EAPS domain sent EAPS Suspend-Preforward-Timer PDUs.

Tx-Query-Link-Status

Indicates the EAPS domain sent EAPS Query-Link-Status PDUs.

Tx-Link-Up

Indicates the EAPS domain sent EAPS Link-Up PDUs and the link is up.

Tx-Unknown

Indicates the number of unknown EAPS PDUs sent by the EAPS domain.

NOTE: Unknown EAPS PDUs can be a new type of PDU that the switch does not track in the sending routine.

Tx-Transmit-Err

Indicates the number of EAPS PDUs the EAPS domain was unable to send because of an error.

Fw-Link-Down

Indicates the number of EAPS Link-Down PDUs received by the EAPS domain and forwarded in slow path.

Fw-Flush-Fdb

Indicates the number of EAPS Flush-Fdb PDUs received by the EAPS domain and forwarded in slow path.

FW-Query-Link-Status

Indicates the number of EAPS Query-Link-Status PDUs received by the EAPS domain and forwarded in slow path.

Fw-Unknown

Indicates the number of unknown EAPS PDUs forwarded in slow path.

NOTE: Unknown EAPS PDUs can be a new type of PDU that the switch does not track in the forwarding routine.

Fw-Transmit-Er

Indicates the number of EAPS PDUs the EAPS domain was unable to forward in slow path because of an error.

Note

Note

Rx and Fw counters—If a PDU is received, processed, and consumed, only the Rx counter increments. If a PDU is forwarded in slow path, both the Rx counter and Fw counter increment.

The following table describes the significant fields and values in the display output of the show eaps counters global command:
Field Description

Rx-Failed

Indicates an error occurred when receiving packets from the Layer 2 forwarding engine.

Rx-Invalid-Vlan-Intf

Indicates that the VLAN interface for the incoming VLAN cannot be found.

Rx-Undersize-Pkt

Indicates the length of the packet is less than the length of the header.

Rx-Invalid-8021Q-Tag

Indicates the VlanTypeLength field in the Ethernet header does not match the default Ethernet value for the 802.1Q tag.

Rx-Invalid-SNAP-Type

Indicates an invalid Subnetwork Access Protocol (SNAP) value in the Ethernet header.

Rx-Invalid-OUI

Indicates the Organizational Unique Identifier (OUI) value in the Ethernet header does not match 00:E0:2B.

Rx-EEP-Unsupported-Version

Indicates an unsupported Extreme Encapsulation Protocol (EEP) version. The EEP version should be 1.

Rx-EEP-Invalid-Length

Indicates the length of the EEP header is greater than the length of the packet.

Rx-EEP-Checksum-Invalid

Indicates the EEP checksum is invalid.

Rx-Domain-Invalid

Indicates the control VLAN‘s incoming PDU is not associated with an EAPS domain.

Rx-Lif-Invalid

Indicates that EAPS is unable to determine the logical interface (LIF) for the ingress port.

Rx-Lif-Down

Indicates the LIF for the ingress port is in the Down state.

Tx-Failed

Indicates an error occurred when sending packets to the Layer 2 forwarding engine.
