Hi everyone,
We have an issue monitoring Vlan-interfaces traffic via SNMP on an HP 5500EI (JD377A).
Recently, at one of our branch offices, we have set up an HP 5500EI with Vlan-interfaces as gateways for the different LAN services (vlans namely, USERS, GUESTS, VOICE, MGMT, DMZ).
It replaced a Cisco ISR 2921 which was the former LAN services gateway, with the HP 5500EI just as aggregation switch not playing any L3 role.
We use PRTG Network Monitor to monitor traffic for WAN links and LAN services for each of our branch offices.
When adding the HP 5500EI to PRTG, all the Vlan-interfaces were correctly discovered, status OK with green icon, but in regards to traffic, there was 'NO DATA' collected for any of them.
First thought was: we need to import a specific HP/H3C MIB to PRTG, but before going any further on this way, I decided to check other options to narrow down the issue, and found that:
- Command display counters rate inbound interface only shows GigabitEth and Ten-GigabitEth physical interfaces. No Bridge-Aggregation interfaces and Vlan-interfaces are shown, but BAGG interfaces can be monitored via SNMP just fine anyway. No conclusion from here.
- Then decided to use Interface Real-Time Monitoring from IMC PLAT 7.1 and sadly IMC also shows zero traffic for any Vlan-interface, same as PRTG.
So, is Vlan-interface SNMP monitoring just not supported on HP 5500EI?
Might there be any workaround that is worth to try to monitor individual VLANs traffic reaching the 5500?
For further topology information, LAN services VLANs spreads over several Bridge-Aggregations to edge switches and some access ports for local directly connected servers, so traffic monitoring over single physical interfaces is not an option at this time.
Thanks in advance for your thoughts and advices.
Regards,
Pablo.
