Hi again, cisco gurus!

Have been looking for SNMP OID that allows to monitor the number of DSP-channels active on Cisco router for some days.

Has someone investigated this task? completely perplexed

Check out this link

Also some additional information --

  • dspu—Sends a notification whenever the operational state of the physical unit (PU) or the logical unit (LU) changes or activation failure is detected. This is from the CISCO-DSPU-MIB, and the notifications are:



    2 newdspuPuActivationFailureTrap


    1 newdspuLuStateChangeTrap

    2 dspuLuActivationFailureTrap

  • dsp—Sends a notification whenever the DSP card goes up or down. This is from the CISCO-DSP-MGMT-MIB, and the notification is:


    1 cdspMIBCardStateNotification

  • Also you could check out these two MIBS, from website



    Hope that helps,

        resources by faxe's for optimizing number of DSP card in router and monitoring  max fax load time.
