Resolution
If you configured the Management application to only allow unique names and you try to
use a name that already exists in the fabric. You can enter a different name for the device
or search for the duplicate name using one of the following procedures:
•
"Searching for a device by name"
•
"Searching for a device by WWN"
•
"Searching for a device in the connectivity map"
Resolution
Make sure that the following prerequisites for Performance Monitoring Data collection are
met.
1 To collect performance statistics for any protocol type (FC/FCIP/FCOE/GE), the snmp
access control list must have an empty list or the Management server IP must be
included in the access control list.
For example, data collection occurs in the following cases.
Case 1: Default access control list is empty
FCRRouter:admin> snmpconfig --show accesscontrol
SNMP access list configuration:
Entry 0: No access host configured yet
Entry 1: No access host configured yet
Entry 2: No access host configured yet
Entry 3: No access host configured yet
Entry 4: No access host configured yet
Entry 5: No access host configured yet
Case 2: Management Server IP included in access control list
FCRRouter:admin> snmpconfig --show accesscontrol
SNMP access list configuration:
Entry 0: Access host subnet area 172.26.1.86 (rw)
Entry 1: No access host configured yet
Entry 2: No access host configured yet
Entry 3: No access host configured yet
Entry 4: No access host configured yet
Entry 5: No access host configured yet
Verification and Troubleshooting.
To add the server IP address to the access control list, use the following command
from the switch CLI:
FCRRouter:admin> snmpconfig --set accesscontrol
To set the default access control, use the following command from the switch CLI:
FCRRouter:admin> snmpconfig --default accesscontrol
