194 CHAPTER 22: QOS CONFIGURATION
For service processor cards, perform the following configurations in VLAN view.
c
CAUTION:
■ Before executing the traffic-priority command on a service processor card,
you must first configure traffic redirection in Ethernet port view to redirect the
packets of a specific VLAN to the service processor card.
■ Before performing this configuration, you must first define the corresponding
ACL and configure the DSCP + Conform-Level -> Service parameters mapping
table and the EXP + Conform-Level -> Service parameters mapping table.
system-index index here is the system index for an ACL rule. When delivering a
rule, the system assigns a globally unique index to it, for convenience of later
retrieval. You can also assign a system index for it when delivering an ACL rule
with this command, but the index value may change while the system is running.
Tabl e 167 Configure traffic priority
Operation Command
Configure traffic priority
which only applies IP group
ACL
traffic-priority inbound ip-group { acl-number | acl-name } [
rule rule [ system-index index ] ] { auto |
remark-policed-service { trust-dscp | dscp dscp-value |
untrusted dscp dscp-value cos cos-value local-precedence
local-precedence drop-priority drop-level } }
Remove traffic priority
setting which only applies
IP group ACL
undo traffic-priority inbound ip-group { acl-number |
acl-name } [ rule rule ]
Configure traffic priority
which applies IP group ACL
and link group ACL at same
time
traffic-priority inbound ip-group { acl-number | acl-name } {
rule rule link-group { acl-number | acl-name } [ rule rule [
system-index index ] ] | link-group { acl-number | acl-name }
rule rule } { auto | remark-policed-service { trust-dscp | dscp
dscp-value | untrusted dscp dscp-value cos cos-value
local-precedence local-precedence drop-priority drop-level } }
Remove traffic priority
setting which applies IP
group ACL and link group
ACL at same time
undo traffic-priority inbound ip-group { acl-number |
acl-name } { rule rule link-group { acl-number | acl-name } [ rule
rule ] | link-group { acl-number | acl-name } rule rule }
Configure traffic priority
which only applies link
group ACL
traffic-priority inbound link-group { acl-number | acl-name } [
rule rule [ system-index index ] ] { auto |
remark-policed-service { trust-dscp | dscp dscp-value |
untrusted dscp dscp-value cos cos-value local-precedence
local-precedence drop-priority drop-level } }
Remove traffic priority
setting which only applies
link group ACL
undo traffic-priority inbound link-group { acl-number |
acl-name } [ rule rule ]
Tabl e 168 Mark packet priority
Operation Command
Mark the packets matching
Layer 3 ACL rule with
priority
traffic-priority inbound ip-group { acl-number | acl-name } [
rule rule [ system-index index ] ] { auto |
remark-policed-service { trust-dscp | dscp dscp-value |
untrusted dscp dscp-value cos cos-value local-precedence
local-precedence drop-priority drop-level } } slot slotid
Remove the mark
