Configuration Check

The device enables you to compare its configuration with those of its neighboring devices.
For this purpose, it uses the data that it received from its neighboring devices via topology recognition (LLDP).
The dialog lists the deviations detected, which affect the performance of the communication between the device and the recognized neighboring devices.

Parameters

Meaning

Number of Errors

Shows the number of errors that the device detected during the configuration check.

Number of Warnings

Shows the number of warnings that the device detected during the configuration check.

Amount of Information

Shows the amount of information that the device detected during the configuration check.

Parameters

Meaning

Rule ID

Rule ID of the deviations having occurred. The dialog combines several deviations with the same rule ID under one rule ID.

Level

Level of deviation between this device's configuration and the recognized neighboring devices. The rule level can have 3 statuses:

information.png Information: The performance of the communication between the two devices is not impaired.

warning.png Warning: The performance of the communication between the two devices may be impaired.

error.png Error: Communication between the two devices is impaired.

Message

The dialog specifies more precisely the information, warnings and errors having occurred.

Note: A neighboring device without LLDP support, which forwards LLDP packets, may be the cause of equivocal messages in the dialog. This occurs if the neighboring device is a hub or a switch without management, which ignores the IEEE 802.1D-2004 standard.
In this case, the dialog displays the devices recognized and connected to the neighboring device as connected to the switch port, even though they are connected to the neighboring device.

Note: If you have more than 39 VLANs configured on the device, the dialog always shows a warning. The reason is the limited number of possible VLAN data sets in LLDP frames with a maximum length. The device compares the first 39 VLANs automatically.
If you have 40 or more VLANs configured on a device, check the congruence of the further VLANs manually, if necessary.

Buttons

Button

Meaning

“Set”

Transfers the changes to the volatile memory (RAM) of the device. To permanently save the changes afterwards, you open the Basic Settings:Load/Save dialog and click “Save”.

“Reload”

Updates the fields with the values that are saved in the volatile memory (RAM) of the device.

“Reset”

Enables the port when disabled by the Port Monitor function.

“Help”

Opens the online help.
