Displaying Flap-List Information for Specific Cable Modems

To use SNMP requests to display flap-list information for a specific cable modem, use the cable modem's
MAC address as the index to retrieve entries from the ccsFlapTable. Use the following procedure to retrieve
flap-list entries for a particular cable modem.
Step 1
Convert the cable modem's MAC address into a dotted decimal string. For example, the MAC address 000C.64ff.eb95
would become 0.12.100.255.235.149.
Step 2 Use the dotted decimal version of the MAC address as the instance for requesting information from the ccsFlapTable.
For example, to retrieve the ccsFlapHits, ccsFlapMisses, and ccsFlapPowerAdjustments values for this cable modem,
you would make an SNMP request for the following objects:
• ccsFlapHits.0.12.100.255.235.149
• ccsFlapMisses.0.12.100.255.235.149
• ccsFlapPowerAdjustments.0.12.100.255.235.149

Example

Assume that you want to retrieve the same flap-list information as the show cable flap-list command for a
cable modem with the MAC address of 000C.64ff.eb95:
