S2989G-24TX Operation Manual
Chapter 6 Security Function Configuration
6-103
Set up a classification rule according to ACL, CoS, VLAN ID, IPv4 Precedent, DSCP,
IPV6 FL to classify the data stream. Different classes of data streams will be
processed with different policies.
Configure a policy map
After data steam classification, a policy map can be created to associate with the
class map created earlier and enter class mode. Then different policies (such as
bandwidth limit, priority degrading assigning new DSCP value) can be applied to
different data streams. You can also define a policy set that can be use in a policy map
by several classes.
Apply QoS to the ports or the VLAN interfaces
Configure the trust mode for ports or bind policies to ports. A policy will only take effect
on a port when it is bound to that port.
The policy may be bound to the specific VLAN.
It is not recommended to synchronously use policy map on VLAN and its port, or else
the policy map priority of the port is higher.
Configure queue management algorithm
Configure queue management algorithm, such as sp, wdrr, and so on.
Configure QoS mapping
Configure the mapping from CoS to IntP, DSCP to IntP, IntP to DSCP, COS, IntP,
DP or queue.
1. Configure class map.
Command
Explanation
Global Mode
Create a class map and enter class
class-map <class-map-name>
map mode; the “no class-map
no class-map <class-map-name>
<class-map-name>” command
deletes the specified class map.
match {access-group <acl-index-or-name>
| ip dscp <dscp-list>| ip precedence
<ip-precedence-list>| ipv6 access-group
<acl-index-or-name> | ipv6 dscp
<dscp-list>| ipv6 flowlabel
<flowlabel-list>|vlan <vlan-list> | cos
<cos-list>| vlan range <vlan-list>}
no match {access-group | ip dscp | ip
Set matching criterion (classify data
stream by ACL, CoS, VLAN ID, IPv4
Precedent, IPv6 FL or DSCP, etc) for
the class map; the no command
deletes specified matching criterion.
precedence | ipv6 access-group | ipv6
dscp | ipv6 flowlabel | vlan | cos| vlan
