Tags: #SNMP
Model: ER7212PC  
Hardware Version: V2
Firmware Version: 2.1.2 Build 20250705 Rel.59147

I got recently a gateway ER7212PC v2.0 together with a EAP653 v1.0 (firmware 1.1.3 Build 20250326 Rel. 59878).

 

I am trying to get proper traffic analysis of my network utilization and would need to get per-port based traffic.

 

I found a number of threads with very similar issues:

 

SNMP ifDescr only works without Omada Controller
ER7206 & SNMP

ER7206 SNMP Interface name to Omada/GW name mapping?

 

And probably some others, but I can't find a per-port analysis, and actually not even a proper description of the interface mapping.

 

From my ER7212PC I get this:

 

IF-MIB::ifDescr.1025 = STRING: default/lo
IF-MIB::ifDescr.1026 = STRING: default/eth0
IF-MIB::ifDescr.1027 = STRING: default/eth1
IF-MIB::ifDescr.1028 = STRING: default/tunl0
IF-MIB::ifDescr.1029 = STRING: default/ip6_vti0
IF-MIB::ifDescr.1030 = STRING: default/sit0
IF-MIB::ifDescr.1031 = STRING: default/ip6tnl0
IF-MIB::ifDescr.1032 = STRING: default/gre0
IF-MIB::ifDescr.1033 = STRING: default/gretap0
IF-MIB::ifDescr.1034 = STRING: default/erspan0
IF-MIB::ifDescr.1035 = STRING: default/bond0
IF-MIB::ifDescr.1036 = STRING: default/inf
IF-MIB::ifDescr.1037 = STRING: default/veth0
IF-MIB::ifDescr.1038 = STRING: default/veth1
IF-MIB::ifDescr.1040 = STRING: default/inf.10
IF-MIB::ifDescr.1041 = STRING: default/br-lan
IF-MIB::ifDescr.1042 = STRING: default/inf.0
IF-MIB::ifDescr.1043 = STRING: default/inf.4091
IF-MIB::ifDescr.1044 = STRING: default/pe-wan3_poe
IF-MIB::ifDescr.1045 = STRING: default/inf.1
 

And from the EAP653:
 

IF-MIB::ifDescr.1 = STRING: lo
IF-MIB::ifDescr.2 = STRING: eth0
IF-MIB::ifDescr.3 = STRING: br0
IF-MIB::ifDescr.4 = STRING: wifi0
IF-MIB::ifDescr.5 = STRING: soc0
IF-MIB::ifDescr.6 = STRING: wifi1
IF-MIB::ifDescr.7 = STRING: soc1
IF-MIB::ifDescr.8 = STRING: ath0
IF-MIB::ifDescr.9 = STRING: ath1
IF-MIB::ifDescr.10 = STRING: ath2
IF-MIB::ifDescr.11 = STRING: ath10
IF-MIB::ifDescr.12 = STRING: bkhap1
 

I know the Omada web interface can show the per-port traffic in the ER and the per SSID, and even frequency traffic in the EAP, but I can't map that from the SNMP output.  For example, in the ER, default/eth0 and default/eth1 seem to have basically symmetrical traffic, but not clear what it belongs to.

 

Trying to identify what is what, I am drawing 5-minutes traffic rate charts for every single one of the 20 interfaces returned by SNMP for the ER, and visually comparing with the per port traffic charts shown at the Omada web interface. I only have 10 hours for now, but there is no match, at all surprise

 

I wonder if someone has a clear mapping of the interfaces, or any suggestion on how to extract the per-port and ideally also the per-SSID traffic.

 

Thanks in advance.

Thank you for your post. At present, neither the gateway nor the access points expose an interface for retrieving real-time traffic statistics per physical port or SSID.
That said, for the APs, as a side note: if you leverage the RFC-based SNMP tree, you can query.iso.org.dod.internet.mgmt.mib-2.ifMIB.ifMIBObjects

@Ethan-TP not sure what should I get from those OID:

root@cinemateka:[~]# snmpwalk -v2c -c ******** 172.16.0.17 .iso.org.dod.internet.mgmt.mib-2.ifMIB.ifMIBObjects
IF-MIB::ifTableLastChange.0 = Timeticks: (23126144) 2 days, 16:14:21.44
root@cinemateka:[~]#
 

 

Nothing else.

Hi  @Ethan-TP 

 

Continuing looking into this I found that the OID RFC1213-MIB::ipRouteIfIndex.0.0.0.0 should return the ifIndex of the "The index value which uniquely identifies the local interface through which the next hop of this route should be reached.  The interface identified by a particular value of this index is the same interface as identified by the same value of ifIndex." (as per IETF RFC1213). So there should be a mapping with the IF-MIB::ifIndex table.

 

But when I poll the ER7212PC:

 

root@cinemateka:[~]# snmpget -v2c -c ***** 192.168.0.1 RFC1213-MIB::ipRouteIfIndex.0.0.0.0
RFC1213-MIB::ipRouteIfIndex.0.0.0.0 = INTEGER: 21
root@cinemateka:[~]#
root@cinemateka:[~]# snmpwalk -v2c -c ***** 192.168.0.1 ifIndex

IF-MIB::ifIndex.1025 = INTEGER: 1025
IF-MIB::ifIndex.1026 = INTEGER: 1026
IF-MIB::ifIndex.1027 = INTEGER: 1027
IF-MIB::ifIndex.1028 = INTEGER: 1028
IF-MIB::ifIndex.1029 = INTEGER: 1029
IF-MIB::ifIndex.1030 = INTEGER: 1030
IF-MIB::ifIndex.1031 = INTEGER: 1031
IF-MIB::ifIndex.1032 = INTEGER: 1032
IF-MIB::ifIndex.1033 = INTEGER: 1033
IF-MIB::ifIndex.1034 = INTEGER: 1034
IF-MIB::ifIndex.1035 = INTEGER: 1035
IF-MIB::ifIndex.1036 = INTEGER: 1036
IF-MIB::ifIndex.1037 = INTEGER: 1037
IF-MIB::ifIndex.1038 = INTEGER: 1038
IF-MIB::ifIndex.1039 = INTEGER: 1039
IF-MIB::ifIndex.1040 = INTEGER: 1040
IF-MIB::ifIndex.1041 = INTEGER: 1041
IF-MIB::ifIndex.1042 = INTEGER: 1042
IF-MIB::ifIndex.1043 = INTEGER: 1043
IF-MIB::ifIndex.1044 = INTEGER: 1044
IF-MIB::ifIndex.1045 = INTEGER: 1045
root@cinemateka:[~]#
 

 

The route 0.0.0.0 sees as ipRouteIfIndex the 21, but there is no 21 in the list returned by ifIndex:

 

root@cinemateka:[~]# snmpget -v2c -c ***** 192.168.0.1 ifIndex.21
IF-MIB::ifIndex.21 = No Such Instance currently exists at this OID
root@cinemateka:[~]#
root@cinemateka:[~]# snmpget -v2c -c ***** 192.168.0.1 ifDescr.21
IF-MIB::ifDescr.21 = No Such Instance currently exists at this OID
root@cinemateka:[~]#
 

so, are those actual interfaces filtered out from the SNMP tree? is there anyway to enable them in the outoput? Can it be requested as a new feature?

 

Thanks!
