Debug Mode
ExtremeWare XOS 11.0 Concepts Guide 327
You cannot enable an ESRP domain:
Before you enable a specific ESRP domain, it must have a domain ID. A domain ID is either a
user-configured number or the 802.1Q tag (VLANid) of the tagged master VLAN. The domain ID must
be identical on all switches participating in ESRP for that particular domain. If you do not have a
domain ID, you cannot enable ESRP on that domain.
Please note the following on the interaction of tagging, ESRP, and ESRP domain IDs:
• If you have an untagged Master VLAN, you must specify an ESRP domain ID.
• If you have a tagged master VLAN, ESRP uses the 802.1Q tag (VLANid) of the master VLAN for the
ESRP domain ID. If you do not use the VLANid as the domain ID, you must specify a different
domain ID.
You cannot delete the master VLAN from the ESRP domain:
If you attempt to remove the master VLAN before disabling the ESRP domain, you see an error
message similar to the following:
ERROR: Failed to delete master vlan for domain "esrp1" ; ESRP is enabled!
If this happens, do the following:
• Disable the ESRP domain using the disable esrp command
• Remove the master VLAN from the ESRP domain using the configure esrp delete master
command.
Debug Mode
The Event Management System (EMS) provides a standard way to filter and store messages generated
by the switch.With EMS, you must enable debug mode to display debug information. You must have
administrator privileges to use these commands. If you do not have administrator privileges, the switch
rejects the commands.
To enable or disable debug mode for EMS, use the following commands:
enable log debug-mode
disable log debug-mode
After debug mode has been enabled, you can configure EMS to capture specific debug information from
the switch. Details of EMS can be found in Chapter 9, “Status Monitoring and Statistics,” on page 125.
TOP Command
The top command is a UNIX-based command that displays real-time CPU utilization information by
process. The output contains a list of the most CPU-intensive tasks and can be sorted by CPU usage,
memory usage, and run time. For more detailed information about the
top command, please refer to
your UNIX documentation.
