Link scheduler configuration task list

IPLink 3210 Series Getting Started Guide
7 • Link scheduler configuration
•
“modem-512” is the title of the profile which is referred to when installing the scheduler
•
“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-
head into the rate limit calculation. Please add 8 bytes to the header-length for AAL5 in this case.
•
“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.
•
“critical_q” is the traffic-class for the higheest priority packet streams that you have selected.
•
“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.
Command cross reference
Comparing IPLink with the Cisco IOS QoS software command syntax often helps administrators to straight-
forwardly configure IPLink devices. In
table 11
the Cisco IOS Release 12.2 QoS commands are in contrast
with the respective IPLink commands.
Link scheduler configuration task list
To configure QoS features, perform the tasks described in the following sections. Depending on your require-
ments some of the tasks are required while other tasks are optional.
•
Defining the access control list profile
•
Creating a service-policy profile (see page 80)
•
Specifying the handling of traffic-classes (see page 82)
•
Devoting the service policy profile to an interface (see page 87)
•
Displaying link arbitration status (see page 88)

For IOS specifies or modifies the bandwidth
allocated for a class belonging to a policy
map. Percent defines the percentage of avail-
able bandwidth to be assigned to the class. for
the IPLink assigns the weight of the selected
source (only used with wfq).
