Solution 2038441.1 : Exalogic Virtual : EMOC is reporting Cisco Management Switch Ports 'port[55]Fa1' and 'port[56]Vl1' are DOWN

Applies to:

Oracle Exalogic Elastic Cloud Software - Version 2.0.6.2.1 and later
Oracle Exalogic Elastic Cloud X2-2 Hardware - Version X2 to X2 [Release X2]
Exalogic Elastic Cloud X3-2 Quarter Rack - Version X3 to X3 [Release X3]
Linux x86-64
Oracle Virtual Server (x86-64)

Symptoms

In Exalogic Virtual releases April 2015 PSU (2.0.6.2.1) and later, issue of EMOC showing following Port DOWN error messages for Cisco management switch is observed.

Cisco Switch Model number is WS-C4948E-F.

Owner: -
Source: 10.XXX.XXX.XXX
Description: port[55]Fa1@10_XX_XX_XX is DOWN. (106709)

Owner: -
Source: 10.XXX.XXX.XXX
Description: port[56]Vl1@10_XX_XX_XX is DOWN. (106709)

Cause

From show ip interface command output on the Cisco Switch it can be verified which IP interfaces are down/up/disabled.

For example, when this command being run on the Cisco Switch, where EMOC is showing the ports are down as follows :

mgmt-switch01>show ip interface
....
Vlan1 is down, line protocol is down =======>port[56]Vl1
Internet protocol processing disabled
.....
FastEthernet1 is down, line protocol is down ======> port[55]Fa1
Internet protocol processing disabled
....

Per above output, it can be clearly seen, both ports are genuinely down and EMOC is correctly alerting that these ports are DOWN.

NOTE

Please note that, ports listed above (i.e. Vlan1 and FastEthernet1) are not being used in this Exalogic use case. In case these ports are being used (e.g. management network etc..), and they are shown as DOWN in EMOC, then this Document is not applicable to that scenario, please contact Oracle Support.

Solution

The Fa1 and Vl1 ports are down/down but not administratively down/down which means those are not disabled.

To fix this issue follow below steps:

NOTE: April 2015 PSU (2.0.6.2.1) or higher, which includes a fix for the following EMOC bug, is a pre-requisite for the procedure provided below:

Bug 20631415 - CISCO SWITCH: INCIDENTS ARE GENERATED FOR ADMINISTRATIVELY DOWN PORTS

Login to the Cisco Switch and perform following procedure:

> enable
The prompt should be changed to #
From enable mode please run:
# conf t
(config)# int fa 1
(config-if)# shut
(config-if)# exit
(config)# int vlan 1
(config-if)# shut
(config-if)# end
# copy running-config startup-config
# show run int fa 1
# show run int vlan 1

This will fix the Fa1 and Vl1 ports down issue.
Login to EMOC console, acknowledge the port alert incidents and mark them as repaired and close them.
