With the current ( at this time) version of firmware v4.4-41, using the default configuration with the addition of a default route to allow routing to and from the switch, the ASE device will allow a MIB browser to walk the MIB.
Example -
To get the switch into default config -
# reload defaults keep-ip
In the default configuration -
Switch# sh run feature snmp all

The default community strings of public and private are configured.
To troubleshoot, verify the switch can ping the SNMP browser and the browser is using the ASE device IP address , default port of 161, and the correct community strings.
