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.

See the following display output for the verbose keyword extension for SID 1 on interface

cable slot 3, port 0:

router# show interface c3/0 sid 1 counters verbose

Sid : 1

Input packets : 39

Input octets : 15964

Output packets : 30

Output octets : 8796

BW requests received : 40

Grants issued : 40

Rate exceeded BW request drops : 0

Rate exceeded DS packet drops : 0
