Troubleshoot Switches
In the event you have issues after you onboard and configure your Universal switches,
here are some possible areas for further exploration:
- Make sure you have configured proper outbound firewall access. The device needs
to be able to access the redirector on TCP 443, a DNS server in order to resolve
the redirector IP address from its hostname, and to access an NTP server in
order to get the correct time. If this access is not available, the secure
connection to the redirector will fail. Refer to Configure Firewall Access.
- Ping the device or initiate a TraceRoute from within ExtremeCloud IQ. Refer to
Establish CLI Access from ExtremeCloud IQ.
- Reset the device to factory
defaults and push a fresh configuration. This also simultaneously resets the
ExtremeCloud IQ device configuration. Refer to Reset the Device to Default Settings.
- Change the Management VLAN to
something with no DHCP: As long as you operate with the latest OS code and
firmware, this issue auto-corrects during reboot.
- Device Update Failed: Use your mouse to hover over this error
message for more details, then refer to Device Update Failure.
- Incorrect VLAN or Trunk: Refer to VLAN or Trunk Issues.
- Switch Stack Issues: Refer to Switch Stack Issues.
- Switch Communication Issues: Refer to IQAgent and Switch Communication Issues.
- Cabletest: Use this tool as a last resort to check switch cables for duplex or
speed issues in the event all other troubleshooting methods fail. Refer to Use Cabletest for Switch Engine Device Duplex or Speed Issues.
