•The management network address/mask (if used) does not contain the IP address of the management station. From the serial console interface, be sure that the management network address/mask contains the IP address of the management station.

Cannot enable a port in multiple VLANs while configuring

VLANS

Action:

A port is part of only one VLAN unless the port is a tagged port. Be sure that the port is enabled as a tagged port.

The switch does not let the user enable two adjacent ports into two different VLANs while assigning the ports to VLANs

Action:

The ports are two adjacent ports that are bundled in a Port Trunk. Two ports that are assigned to a Port Trunk cannot be assigned to two different VLANs. Either break the trunk to assign it two different VLANs or assign the ports to one VLAN.

While using TFTP to download firmware, the switch fails to connect to the TFTP server, or after connection the download fails

Action:

•The TFTP server is not available to connect to or there is connectivity failure between the switch and TFTP server.

•Be sure that the IP address of the TFTP server is correct.

•Be sure that the TFTP server exists on the same network and VLAN as the switch.

•Be sure that the TFTP server can be pinged from the switch and vice versa.

•The firmware file is not found on the TFTP server. The file name could be wrong.

•Be sure that a valid firmware file exists on the TFTP server to download to the switch.

•On the switch, check the file name configured to download.

•The TFTP server was started with a configured directory. The switch must be configured using the full path name, if it is not in the directory specified in the TFTP server.

The switch fails to connect to the TFTP server while using TFTP to download or upload a configuration file, or after connection the download or upload fails

Action:

•The TFTP server is not available to connect or there is a connectivity failure between the switch and the TFTP server.
