Brocade Communications Systems 53-1002373-02 Displaying device status and temperature readings

7 Managing the device

If an I2C failure has not occurred, there will be no I2C messages in the static log, dynamic log, or SNMP log server. The following example shows output from the show logging command when there is no I2C failure.

Brocade# show logging
Syslog	logging: enabled (0 messages dropped, 0 flushes, 1 overruns)
Buffer	logging: level ACDMEINW, 50 messages logged
level code: A=alert C=critical D=debugging		M=emergency E=error
I=informational N=notification W=warning
Static	Log Buffer:	middle, Not Installed (FAILED)
Apr 16	18:21:25:A:System: Power Supply 2 ,
Apr 16	18:21:25:A:System: Power Supply 3 ,	top, Not Installed (FAILED)
Dynamic Log Buffer (50 lines):		MED (75%)
Mar 28	12:36:47:A:System: Set fan speed to
Mar 25	21:40:47:A:System: Set fan speed to	MED-HI (90%)
Mar 25	16:30:47:A:System: Set fan speed to	MED (75%)
Mar 23	23:12:07:A:System: Set fan speed to	MED-HI (90%)

If the system detects a major I2C failure, the system prevents the management module from accessing devices through the l2C serial bus. The output from the show chassis command and the show temperature command reflect this action, as shown in these examples.

Brocade# show chassis

*** Note: ***

*** Global I2C Error Indicator is set (severity: Major). ***

*** All I2C access are skipped. ***

The following output is from the show temperature command with the GIEI set to major severity.

Brocade# show temperature

Displaying device status and temperature readings

You can display the following information about the router:

•Power-on priority of the device slots

•Status of the fans

•Temperature readings of the management, switch fabric, interface, and fan control modules and the interval at which the system reads the temperature of these modules

•MAC address of the device
