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
