or search for the duplicate name using one of the following procedures:
• “Searching for a device by name” on page 82 in the Configure Names dialog box
• “Searching for a device by WWN” on page 83 in the Configure Names dialog box
• “Searching for a device in the connectivity map” on page 139
Problem Resolution
An error message with the following text
displays:
Real Time statistics collection has failed.
Please see master log for details.
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
