byte dscp order fragments (OPTIONAL) Enter the keyword byte to count bytes processed by the filter. (OPTIONAL) Enter the keyword dscp to match to the IP DSCP values. (OPTIONAL) Enter the keyword order to specify the QoS priority for the ACL entry. Range: 0-254 (where 0 is the highest priority and 254 is the lowest; lower order numbers have a higher priority) Default: If the order keyword is not used, the ACLs have the lowest order by default (255). Enter the keyword fragments to use ACLs to control packet fragments. Defaults Not configured. Command Modes CONFIGURATION-IP ACCESS-LIST-EXTENDED Command History Usage Information Version 8.3.16.1 Introduced on MXL 10/40GbE Switch IO Module The order option is relevant in the context of the Policy QoS feature only. For more information, refer to the Quality of Service (QoS) chapter of the FTOS Configuration Guide. In the MXL Switch, you can configure either count (packets) or count (bytes). However, for an ACL with multiple rules, you can configure some ACLs with count (packets) and others as count (bytes) at any given time. Related Commands deny tcp deny udp ip access-list extended Assigns a filter to deny TCP packets. Assigns a filter to deny UDP packets. Creates an extended ACL. deny icmp Configure a filter to drop all or specific ICMP messages. Syntax deny icmp {source mask | any | host ip-address} {destination mask | any | host ip-address} [dscp] [message-type] [count [byte]] [order] [fragments] To remove this filter, you have two choices: • Use the no seq sequence-number command if you know the filter's sequence number. • Use the no deny icmp {source mask | any | host ip-address} {destination mask | any | host ip-address} command. Parameters source mask any host ip-address destination dscp Enter the IP address of the network or host from which the packets were sent. Enter a network mask in /prefix format (/x) or A.B.C.D. The mask, when specified in A.B.C.D format, may be either contiguous or non-contiguous. Enter the keyword any to specify that all routes are subject to the filter. Enter the keyword host followed by the IP address to specify a host IP address. Enter the IP address of the network or host to which the packets are sent. Enter this keyword to deny a packet based on DSCP value. Range: 0-63 Access Control Lists (ACL) | 103

Information
The
order
option is relevant in the context of the Policy QoS feature only. For more information, refer
to the
Quality of Service (QoS)
chapter of the
FTOS Configuration Guide
.
In the MXL Switch, you can configure either count (packets) or count (bytes). However, for an ACL
with multiple rules, you can configure some ACLs with count (packets) and others as count (bytes) at
any given time
.
