getsnmp not working for "extremeRtStats"

Hi community,

I have a Summit48si and need to monitor port errros like CRC & collisions. I see from MIB files there are following OIDs available:
- extremeRtStatsCRCAlignErrors extremeRtStatsCRCAlignErrors 1.3.6.1.4.1.1916.1.11.1.1.3
- extremeRtStatsCollisions extremeRtStatsCollisions 1.3.6.1.4.1.1916.1.11.1.1.8

When I try to featch them I got message OID does not exist.
Using "snmpwalk" I see "extremeRtStats", module that contains all port counters is also not recognized:
snmpwalk -v2c -c private 10.121.27.39 1.3.6.1.4.1.1916.1.11
SNMPv2-SMI::enterprises.1916.1.11 = No Such Object available on this agent at this OID

Is there any extra configuration to get these port statistics available via SNMP?

Thanks your help in advance,
Wanderley

Summit48Si, ancient but good stuff, I think you need to enable RMon on the ports to get these mibs working.

This is a FlexView I created to monitor CRC errors on uplink ports. Many of our customers are running 10g on old 62.5u fiber, so this became a necessary standard addition to NetSight installations.

If you use Console you can run it on ports groups instead of devices. But for what you're looking to do the web client should work fine.

I do think you need to enable RMon.

I found issue, according to Extreme manual is necessary to "enable rmon" to get port statistics working.
As soon rmon was enabled I got port statistics via SNMP available, see bellow:
1) With “rmon” disabled (by default is disabled):

#> snmpwalk -v2c -c public 10.0.0.1 1.3.6.1.4.1.1916.1.11.1.1.3.57
SNMPv2-SMI::enterprises.1916.1.11.1.1.3.57 = No Such Instance currently exists at this OID

2) With "rmon enabled" via command "enable rmon": #> snmpwalk -v2c -c public 10.0.0.1 1.3.6.1.4.1.1916.1.11.1.1.3.57
SNMPv2-SMI::enterprises.1916.1.11.1.1.3.57 = Counter32: 1

Thanks for all support got on this forum
