“rate-limit 512” allows no more than 512 kbit/sec to pass which avoids queueing in the modem.
•
“header-length 20” specifies how many framing bytes are added by the modem to “pack” the IP packet on
the link. The framing is taken into account by the rate limiter.

“atm-modem” tells the rate limiter that the access link is ATM based. This option includes the ATM over-

“source traffic-class” enters a sub-mode where the specific handling for a traffic-class is described. The list of
sources in the service-policy profile tells the arbiter which “traffic sources” to serve.

“local-voice” is the predefined traffic-class for locally terminated voice packet streams.

“priority” means that packet of the source being described are always passed on immediately, packets of
other classes follow later if the rate limit permits.
