Cisco WLC – IOS Based WLC AP Count through SNMP (5760, 3850, 3650)

I had a hard time to find the correct OID and ended with doing a snmpwalk and try to find the right OID with a grep…
But i think i made it 🙂

Crosschecked on 2 5760 Clusters and i got the correct count on both, also tried to reboot some APs and the count seems correct to me.
Note: I use 3.6.1 so maybe you get a different result with another software version.

1.3.6.1.4.1.9.9.999999.1.1.1.11.0

Interesting is that i found two other OIDs that report the same value.

1.3.6.1.4.1.9.9.999999.1.1.1.17.0
1.3.6.1.4.1.9.9.999999.1.1.1.18.0

Use ? “literal” in IOS

As we all know, the Question mark in IOS is used as interactive help, but what about a ? in a password?
This could for example be a task in your CCIE Lab or at least in on of the many preparation labs.

To use the ? literal just enter crtl+v and then ?

Rack1SW3(config)#username cisco password SECR?
LINE    <cr>

ctrl+v ?

Rack1SW3(config)#username cisco password SECR?
Rack1SW3(config)#

Easy stuff but good to know!
Of course the ? can also be used in ACL Names, Route-maps, etc…
