Help with SNMP low level discovery on ifAlias

[bcsx123]

Hi.

I need to discovery every interface with alias lan or wan in Cisco and Huawei routers.
I have changed the default discovery "Network interfaces" on the default template "Template SNMP Interfaces". See the attachments 1 and 2.

The discovery on the Huawei router don't work. In the log I see:

  3795:20150320:153838.206 SNMP agent item "ifAlias" on host "Huawei" failed: first network error, wait for 15 seconds
  3797:20150320:153912.348 SNMP agent item "ifAlias" on host "Huawei" failed: another network error, wait for 15 seconds

The discovery on the Cisco router works but after a poll, the incoming/outgoing traffic on the 2 WAN become unsupported. In the log I see:

item "Cisco:ifInOctets[...WAN...]" became not supported: No Such Instance currently exists at this OID

But the incoming/outgoing traffic on the LAN works well. The unique difference is that the alias for the lan is short and the alias for the two WANs is a string of 62 characters including letter, numbers, spaces, slashes and minus.

I don't know how to solve this problem. I need to discover only the interfaces with specific strings in the alias. How can I do this?

EDIT:

I have understand that the problem is related to the subinterfaces. In the router the physical interfaces and the subinterfaces have the same alias but for the subinterfaces the traffic doesn't exist.

Thank you.

Bye.

Good day. Did you manage to solve the problem with Huawei?
