Configure a Standard IP ACL
To configure an ACL, use commands in IP ACCESS LIST mode and INTERFACE mode.
For a complete list of all the commands related to IP ACLs, refer to the
Dell Networking OS Command
Line Interface Reference Guide
. To set up extended ACLs, refer to
Configure an Extended IP ACL
.
A standard IP ACL uses the source IP address as its match criterion.
1.
Enter IP ACCESS LIST mode by naming a standard IP access list.
CONFIGURATION mode
ip access-list standard
access-listname
2.
Configure a drop or forward filter.
CONFIG-STD-NACL mode
seq
sequence-number
{deny | permit} {
source
[
mask
] | any | host
ip-address
}
[count [byte] [dscp] [order] [fragments]
NOTE: When assigning sequence numbers to filters, keep in mind that you might need to insert a
new filter. To prevent reconfiguring multiple filters, assign sequence numbers in multiples of five.
To view the rules of a particular ACL configured on a particular interface, use the
show ip accounting
access-list
ACL-name
interface
interface
command in EXEC Privilege mode.
Example of Viewing the Rules of a Specific ACL on an Interface
The following is an example of viewing the rules of a specific ACL on an interface.
Dell#show ip accounting access-list ToOspf interface gig 1/6
Standard IP access list ToOspf
seq 5 deny any
seq 10 deny 10.2.0.0 /16
seq 15 deny 10.3.0.0 /16
seq 20 deny 10.4.0.0 /16
seq 25 deny 10.5.0.0 /16
seq 30 deny 10.6.0.0 /16
seq 35 deny 10.7.0.0 /16
seq 40 deny 10.8.0.0 /16
seq 45 deny 10.9.0.0 /16
seq 50 deny 10.10.0.0 /16
Dell#
The following example shows how the
seq
command orders the filters according to the sequence
number assigned. In the example, filter 25 was configured before filter 15, but the
show config
command displays the filters in the correct order.
Dell(config-std-nacl)#seq 25 deny ip host 10.5.0.0 any log
Dell(config-std-nacl)#seq 15 permit tcp 10.3.0.0 /16 any
Dell(config-std-nacl)#show config
!
ip access-list standard dilling
seq 15 permit tcp 10.3.0.0/16 any
seq 25 deny ip host 10.5.0.0 any log
Dell(config-std-nacl)#
To delete a filter, use the
no seq sequence-number
command in IP ACCESS LIST mode. If you are
creating a standard ACL with only one or two filters, you can let Dell Networking OS assign a sequence
