That is indeed a pain.
Does anyone know if the lack of VE interface counters is a hardware
problem? Does it change with a VM-1 card installed?
I've started looking at how to extract the information from sFlow, but
annoyingly I can't even seem to get sFlow exporting working.
SSH@foundry1#sh run | inc sflow
sflow enable
sflow sample 512
sflow polling-interval 30
sflow destination w.x.y.z
SSH@foundry1#conf t
SSH@foundry1(config)#int e1/3
SSH@foundry1(config-if-e1000-1/3)#sflow forwarding
SSH@foundry1(config-if-e1000-1/3)#exit
SSH@foundry1(config)#exit
SSH@foundry1#sh sflow
sFlow services are enabled.
sFlow agent IP address: 10.134.221.4
Collector IP w.x.y.z, UDP 6343
Polling interval is 30 seconds.
Configured default sampling rate: 1 per 512 packets.
Actual default sampling rate: 1 per 512 packets.
0 UDP packets exported
0 sFlow samples collected.
No ports configured for sFlow sampling.
Module Sampling Rates
SSH@foundry1#sh run int e1/3
!Building configuration...
!Current configuration : 47 bytes
interface ethernet 1/3
port-name Gi0/1 Net1
!
So basically it's just ignoring the sFlow port configuration. I've read
through the Foundry docs and can't seem to figure out why. The interface
e1/3 is one of the GE ports on the B4GMR4 card, and the box is running
07.7.01T53 (B2R07701).
Feels like I'm missing something very obvious, but I can't see what.
