This version replaces the Simple Network Management Protocol (SNMP) stack with an open-source Net-SNMP for network management. The major set of features the operating system SNMP supports include:
The following table describes the limitations of implementing open-source Net-SNMP:
| Feature | Limitation |
|---|---|
| Remote Monitoring (RMON) alarms | Only RMON Alarm MIBs are supported |
| Notification-table | Net-SNMP implementation supports only default table with no filtering |
| SNMP-COMMUNITY-MIB | This MIB must be implemented outside of the stack and is not available in Net-SNMP |
| Switch Network Monitoring (SMON) MIB | Not supported |
| show snmp statistics | Will not show VR-specific counters |
| Smarttraps | Not available in this version |
| 3DES | 3DES is not supported as a privacy protocol for SNMPv3 users |
| Filter-Profile functionality | Not supported |
| Community with blank string | Not supported |
| Traps sent when no VR is specified | Send traps by default on Management VR if no VR is specified |
The following commands are modified based on the limitations described in the previous section:
configure snmpv3 add user - removes the 3DES option.
show checkpoint-data, restart process, start process, terminate process - removes snmpSubAgent.
show snmp vr-name - shows the combined statistics of all the VRs in the switch and not specifically for each VR.
The following commands are not supported in this version based on the limitations of this feature:
The following EMS Messages are not supported in this version:
