Symptoms

  • Recently upgraded to DCNM 7.2.3
  • Unable to modify zones via "Edit Local Full Zone Database" in DCNM. Getting the following error message: 
Snmp: The login user does not have permission to edit zones for switches in selected VSAN. To edit zones please discover the switches in selected VSAN using SNMP User with read/write permission
  • Switches also shows status Timeout (Client) in DCNM:

Cause

.

Resolution

 
  • From the DCNM webUI > Admin > Server Properties area, set the fabric.enableNpvDiscovery parameter to false. 
# Allow NPV discovery:
# (Default to true)
fabric.enableNpvDiscovery=false
  • Apply the change
  • Restart DCNM SAN/LAN server
  • Rediscover the fabric(s)
Note: In some instances where NpvDiscovery is not enabled, increasing the DCNM SNMP timeout setting may resolve this issue:

Increase the DCNM SNMP Timeout value
  1. Select File > Preferences.  
  2. In the SNMP tab, enter 30
  3. Select OK.    
  4. Restart the SAN client 
  5. Verify whether timeout error is still present

Note: Customers should also work with their networking team to ensure all the required TCP/UDP ports are opened on the firewall as this may also cause this issue
