SNMP - OID type is unknown and value is empty

Dear community experts,

 

Please help me to solve my problem!

 

I need to get a value for dot1x port status. I find the OID - 1.1.8802.1.1.1.1.2.1.1.5,

but when I issue

snmpGet.exe -r:my_ip  -v:2c -c:"mypassword" -o:.1.1.8802.1.1.1.1.2.1.1.5

 

I get response

OID=.1.1.8802.1.1.1.1.2.1.1.5
Type=<Unknown>
Value=

snmpwalk also doesn't show me any OIDs that start with 1.1.

 

Dot1x is enabled on the switch and "show dot1x all summary" shows me dot1x port status

My image  cat4500e-universalk9.SPA.03.08.05.E.152-4.E5.bin  supports mib - IEEE8021-PAE-MIB

IEEE8021-PAE-MIB has module identity ieee8021paeMIB.   Translate that to numeric OID shows it starts with 1.0.8802.

 

snmptranslate -On -IR ieee8021paeMIB -m +ALL

.1.0.8802.1.1.1

Hi,

as suggested by Daniel, try a snmpwalk with 1.0.8802.1.1.1.1.2.1.1.5 instead.

 

The cisco object navigator shows a wrong ISO tree for quite some time and unfortunately they haven't reacted to my feedbacks so far...

Any assumption? Anyone?

Re: SNMP - OID type is unknown and value is empty

I also try the same on 3750X and 3560CX switches, I also checked their images with Cisco SNMP Object Navigator and they all claim support for IEEE8021-PAE-MIB

 

And what's more interesting all switches 3750, 3560 and 4500, shows the same output

Switch#show snmp mib 
dot1xPaeSystem.1 
dot1xPaePortEntry.2 
dot1xPaePortEntry.3 
dot1xPaePortEntry.4 
dot1xPaePortEntry.5 
dot1xAuthConfigEntry.1 
dot1xAuthConfigEntry.2 
dot1xAuthConfigEntry.3 
--More-- 

So it's definitely something related to dot1x  inside...

But how can I get the values?(

Maybe I'm doing something wrong?
