Example of Viewing the Rules of a Specic ACL on an Interface
The following is an example of viewing the rules of a specic 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 lters according to the sequence number assigned. In the example, lter
25 was congured before lter 15, but the show config command displays the lters 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 monitor 300
Dell(config-std-nacl)#show config
!
ip access-list standard dilling
seq 15 permit tcp 10.3.0.0/16 any monitor 300
seq 25 deny ip host 10.5.0.0 any log
Dell(config-std-nacl)#
To delete a lter, use the no seq sequence-number command in IP ACCESS LIST mode. If you are creating a standard ACL with only
one or two lters, you can let Dell Networking OS assign a sequence number based on the order in which the lters are congured. The
software assigns lters in multiples of 5.
Conguring a Standard IP ACL Filter
If you are creating a standard ACL with only one or two lters, you can let Dell Networking OS assign a sequence number based on the
order in which the lters are congured. The software assigns lters in multiples of ve.
1 Congure a standard IP ACL and assign it a unique name.
CONFIGURATION mode
ip access-list standard access-list-name
2 Congure a drop or forward IP ACL lter.
CONFIG-STD-NACL mode
{deny | permit} {source [mask] | any | host ip-address} [count [byte] [dscp] [order]
[fragments]
When you use the log keyword, the CP logs details about the packets that match. Depending on how many packets match the log entry
and at what rate, the CP may become busy as it has to log these packets’ details. The following example shows a standard IP ACL in which
Dell Networking OS assigns the sequence numbers. The lters were assigned sequence numbers based on the order in which they were
congured (for example, the rst lter was given the lowest sequence number). The show config command in IP ACCESS LIST mode
displays the two lters with the sequence numbers 5 and 10.
Example of Viewing a Filter Sequence for a Specied Standard ACL and for an Interface
Dell(config-route-map)#ip access standard acl1
Dell(config-std-nacl)#permit 10.1.0.0/16 monitor 177
Dell(config-std-nacl)#show config
!
ip access-list standard acl1
seq 5 permit 10.1.0.0/16 monitor 177
