Monitoring Interface Status on AAC Devices
A size limit has been implemented on the number of SNMP requests that can be
sent to an ACC device. This size limit varies depending on the firmware revision
and the network connectivity of the AAC device. The DCE Manager Device
Display has a default limit set on the number of interface status requests that can
be sent to an ACC device in a single SNMP request. The default limit is 5.
You can change this default by modifying the attGEMdd*pduSize parameter in
the /opt/OV/att/attGEM/GEMDD.res configuration file (or the
/usr/OV/att/attGEM/GEMDD.res configuration file on AIX systems). Setting
the value too low causes a high number of SNMP requests to be sent to the
device. Setting the value too high can cause the AAC device not to respond to
status polls. If the interfaces on the AAC device display remain in the blue
“unknown” state the user should reduce the value of the attGEMdd*pduSize
parameter, or unmanage one or more of the interfaces that are in an “unknown”
state.
