Configuring A Standard Ip Acl Filter - Dell S6100 Configuration Manual

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 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 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 number based on the order in which the filters are configured. The
software assigns filters in multiples of 5.

Configuring a Standard IP ACL Filter

If you are creating a standard ACL with only one or two filters, you can let Dell Networking OS assign a sequence number based on the
order in which the filters are configured. The software assigns filters in multiples of five.
1 Configure a standard IP ACL and assign it a unique name.
CONFIGURATION mode
ip access-list standard access-list-name
2 Configure a drop or forward IP ACL filter.
CONFIG-STD-NACL mode
{deny | permit} {source [mask] | any | host ip-address} [count [byte] [dscp] [order] [monitor
[session-id]] [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 filters were assigned sequence numbers based on the order in which they were
configured (for example, the first filter was given the lowest sequence number). The show config command in IP ACCESS LIST mode
displays the two filters with the sequence numbers 5 and 10.
Example of Viewing a Filter Sequence for a Specified 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
Dell(config-std-nacl)#
To view all configured IP ACLs, use the show ip accounting access-list command in EXEC Privilege mode.
The following examples shows how to view a standard ACL filter sequence for an interface.
Dell#show ip accounting access example interface gig 4/12
