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] [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 EMC 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
DellEMC(config-route-map)#ip access standard acl1
DellEMC(config-std-nacl)#permit 10.1.0.0/16 monitor 177
DellEMC(config-std-nacl)#show config
!
ip access-list standard acl1
seq 5 permit 10.1.0.0/16 monitor 177
DellEMC(config-std-nacl)#
To view all congured IP ACLs, use the show ip accounting access-list command in EXEC Privilege mode.
The following examples shows how to view a standard ACL lter sequence for an interface.
DellEMC#show ip accounting access example interface gig 4/12
Extended IP access list example
seq 15 deny udp any any eq 111
seq 20 deny udp any any eq 2049
seq 25 deny udp any any eq 31337
seq 30 deny tcp any any range 12345 12346
seq 35 permit udp host 10.21.126.225 10.4.5.0 /28 monitor 300
seq 40 permit udp host 10.21.126.226 10.4.5.0 /28
seq 45 permit udp 10.8.0.0 /16 10.50.188.118 /31 range 1812 1813
seq 50 permit tcp 10.8.0.0 /16 10.50.188.118 /31 eq 49 monitor 349
seq 55 permit udp 10.15.1.0 /24 10.50.188.118 /31 range 1812 1813
To delete a lter, enter the show config command in IP ACCESS LIST mode and locate the sequence number of the lter you want to
delete. Then use the no seq sequence-number command in IP ACCESS LIST mode.
Congure an Extended IP ACL
Extended IP ACLs lter on source and destination IP addresses, IP host addresses, TCP addresses, TCP host addresses, UDP addresses,
and UDP host addresses.
The trac passes through the lter in the order of the lter’s sequence and hence you can congure the extended IP ACL by rst entering
IP ACCESS LIST mode, and then assigning a sequence number to the lter.
Conguring Filters with a Sequence Number
To congure lters with a sequence number, use the following commands.
1 Enter IP ACCESS LIST mode by creating an extended IP ACL.
CONFIGURATION mode
ip access-list extended access-list-name
2 Congure a drop or forward lter.
CONFIG-EXT-NACL mode
