Monitoring and Logging System Information 357
• Stack ID —This is the assigned stack ID. For the Dell Networking N1500,
N2000, N3000, and N4000 Series switches, the stack ID number is always
1. The number 1 is used for systems without stacking ability. The stack
master is used to collect messages for the entire stack.
• Component name—The component name for the logging component.
Component “UNKN” is substituted for components that do not identify
themselves to the logging component.
• Thread ID—The thread ID of the logging component.
• File name —The name of the file containing the invoking macro.
• Line number —The line number which contains the invoking macro.
• Sequence number —The message sequence number for this stack
component. Sequence numbers may be skipped because of filtering but
are always monotonically increasing on a per-stack member basis.
• Message — Contains the text of the log message.
What Factors Should Be Considered When Configuring Logging?
Dell recommends that network administrators deploy a syslog server in their
network and configure all switches to log messages to the syslog server. Switch
administrators should also consider enabling persistent logging on the switch.
When managing logs on a stack of switches, the RAM log and persistent log
files exist only on the top of stack platform. Other platforms in the stack
forward their messages to the top of stack log.
Logging of debug level messages is intended for use by support personnel.
The output is voluminous and cryptic and, because of the large number of
messages generated, can adversely affect switch operations. Set the logging
level to debug only under the direction of support personnel.
