SNMP VLAN Statistics

I'm playing around with SNMP monitoring to get traffic statistics by VLAN. Now I figured out, that almost all VLAN interfaces have the same bytes in counters (also all other counters are the same abo...

Did anyone work out a way to get the Bandwidth stats per vlan from LTM? I have tried F5-BIGIP-SYSTEM-MIB::sysVlanStatBytesIn and F5-BIGIP-SYSTEM-MIB::sysVlanStatBytesOut and get the same values across all vlans in the same trunk i.e summation. I need individual stats per vlan

I have tried the IP-MIB also (32bit counter) which is inaccurate - potentially loops around?

snmpwalk -O n -v 2c-c public sdvip2 IF-MIB::ifInOctets.1184 .1.3.6.1.2.1.2.2.1.10.1184 = Counter32: 361794194 snmpwalk -O n -v 2c-c public sdvip2 IF-MIB::ifOutOctets.1184 .1.3.6.1.2.1.2.2.1.16.1184 = Counter32: 360878034

64 bit IF-MIB does not work snmpwalk -v 2c -c public xxxx .1.3.6.1.2.1.31.1.1.1.10 IF-MIB::ifHCOutOctets = No Such Object available on this agent at this OID snmpwalk -v 2c -c public xxxx .1.3.6.1.2.1.31.1.1.1.6 IF-MIB::ifHCInOctets = No Such Object available on this agent at this OID

If anyone got this to work for a specific vlan please let me know how. Im on 11.5

thanks

Hi Chris, I realized the same issue - so this isn't fixed in 11.5. I don't know how I've tested this in my lab. Now on productive system I couldn't find any way to get correct stats. (neither with sysVlanStat nor sysVlanxStat) I've no 11.6 production system right now, so I cannot answer, if this issue is fixed with 11.6 Philipp
