Version Description
9.10(0.0) Introduced on the S6000.
Usage
Information
The dynamic-buffer-limit command restricts the amount of dynamic memory that a particular
class of traffic can use. If the traffic consumes more than the configured buffer limit, the system drops
the traffic during congestion, providing a predictable latency.
Example
Dell (conf)# qos-policy-output VOIP
Dell (conf-qos-policy-out)#bandwidth-percentage 1
Dell (conf-qos-policy-out)#rate-shape 10000 committed 1000
Dell (conf-qos-policy-out)#dynamic-buffer-limit 10000
match ip access-group
Configure match criteria for a class map, based on the access control list (ACL).
NOTE:
IPv6 class-maps and IP-any class-maps do not match. This condition is true for IPv6 and IP-any class-maps on both
ACLs as well as VLANs.
Syntax
[seq sequence number] match ip access-group access-group-name [set-ip-dscp
value | set-color value]
To remove ACL match criteria from a class map, use the no [seq sequence number] match ip
access-group access-group-name [set-ip-dscp value | set-color value]
command.
Parameters
seq sequence
number
(OPTIONAL) Enter the keyword seq then the sequence number. The range is from
1 to 100. By default, the sequence number are assigned in multiples of five.
access-group-
name
Enter the ACL name whose contents are used as the match criteria in determining
if packets belong to the class the class-map specifies.
set-ip-dscp value (OPTIONAL) Enter the keywords set-ip-dscp then the IP DSCP value. The
matched traffic is marked with the DSCP value. The range is from 0 to 63.
set-color value (Optional) Enter the keyword set-color followed by a color value. Traffic that fulfills
the match criteria is marked with the color value that you specify. The default value
is Yellow.
Defaults none
