Description
This article describes steps to take when ports do not update properly with the current VLAN information. Symptoms include:
Scope
Version: 8.x
Solution
VLANs are read using various methods depending upon the device: SNMP, CLI or REST API. Verify the following:
If SNMP credentials fail, see related KB article below.
If CLI credentials fail, see related KB article below.
If using SNMP v3: Switches using SNMP v3 must have unique Engine IDs (msgAuthoritativeEngineID). They are used to identify the device. If multiple switches have the same Engine ID, sporadic unpredictable results may occur.
2. If Cisco switch, verify the CLI banner is appropriate. See related KB article below.
3. If running older code, check for any related fixes in newer code listed under the Enhancements and Addressed Issues section of the Release Notes in the Fortinet Document Library.
If behavior persists, further debugging may be required. Contact Support for assistance.
