Chapter 4 Troubleshooting the System

Understanding Show Command Responses

•Counters for each type of upstream slot scheduled in the MAPs for this upstream channel---The “Init Mtn IEs 800” means that the MAC scheduler has added 800 initial maintenance information elements (slots) at the time the show command was issued.

•MAC scheduling statistics to display what percentage of the upstream bandwidth is utilized for each type of slot on an average.

Show Interface Cable SID

To display per-SID counters for bandwidth requests, use the show interface cable privileged EXEC command: show interface cable interface sid [sid] counters verbose. Data transport over the RF link uses the registered SID address, rather than the Ethernet address. This allows multiple hosts to access the network by using a single cable modem.

Note Cisco IOS Release 12.0(7)XR2 and 12.1(1a)T1 adds the verbose option to provide SID details.
