Usage The order option is relevant in the context of the Policy QoS feature only. For more information, refer Information 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. Most ACL rules require one entry in the CAM. However, rules with TCP and UDP port operators (gt, lt, range) may require more than one entry. The range of ports is configured in the CAM based on bit mask boundaries; the space required depends on exactly what ports are included in the range. For example, an ACL rule with TCP port range 4000 - 8000 uses eight entries in the CAM: Rule# Data Mask From To #Covered 1 0000111110100000 1111111111100000 4000 4031 32 2 0000111111000000 1111111111000000 4032 4095 64 3 0001000000000000 1111100000000000 4096 6143 2048 4 0001100000000000 1111110000000000 6144 7167 1024 5 0001110000000000 1111111000000000 7168 7679 512 6 0001111000000000 1111111100000000 7680 7935 256 7 0001111100000000 1111111111000000 7936 7999 64 8 0001111101000000 1111111111111111 8000 8000 1 Total Ports: 4001 But an ACL rule with TCP port lt 1023 takes only one entry in the CAM: Rule# Data Mask From To #Covered 1 0000000000000000 1111110000000000 0 1023 1024 Total Ports: 1024 Related Commands deny deny udp Assigns a filter to deny IP traffic.

Usage

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.

Most ACL rules require one entry in the CAM. However, rules with TCP and UDP port operators (

range

) may require more than one entry. The range of ports is configured in the CAM based on bit

mask boundaries; the space required depends on exactly what ports are included in the range.

For example, an ACL rule with TCP port

range

4000 - 8000

uses eight entries in the CAM:

But an ACL rule with TCP port lt 1023 takes only one entry in the CAM:

Commands

deny udp

Configure a filter to drop UDP packets meeting the filter criteria.

Syntax

deny udp

{

source mask

host

} [

[

]] {

} [

dscp

] [

] [

]

To remove this filter, you have two choices:

•

Use the

seq

sequence-number

command if you know the filter’s sequence number.

•

Use the

deny udp

{

source mask

any

host

ip-address

} {

destination mask

any

host

ip-address

} command.
