Counting Acl Hits; Configure Ingress Acls - Dell S6100 Configuration Manual

NOTE: The number of entries allowed per ACL is hardware-dependent. For detailed specification about entries allowed
per ACL, refer to your line card documentation.
4 Apply rules to the new ACL.
INTERFACE mode
ip access-list [standard | extended] name
To view which IP ACL is applied to an interface, use the show config command in INTERFACE mode, or use the show running-
config command in EXEC mode.
Example of Viewing ACLs Applied to an Interface
Dell(conf-if)#show conf
!
interface TenGigabitEthernet 1/1/1/1
ip address 10.2.1.100 255.255.255.0
ip access-group nimule in
no shutdown
Dell(conf-if)#
To filter traffic on Telnet sessions, use only standard ACLs in the access-class command.

Counting ACL Hits

You can view the number of packets matching the ACL by using the count option when creating ACL entries.
1 Create an ACL that uses rules with the count option. Refer to
2 Apply the ACL as an inbound or outbound ACL on an interface.
3
show ip accounting access-list
EXEC Privilege mode
View the number of packets matching the ACL.

Configure Ingress ACLs

Ingress ACLs are applied to interfaces and to traffic entering the system.
These system-wide ACLs eliminate the need to apply ACLs onto each interface and achieves the same results. By localizing target traffic, it
is a simpler implementation.
To create an ingress ACL, use the ip access-group command in EXEC Privilege mode. The example shows applying the ACL, rules to
the newly created access group, and viewing the access list.
Example of Applying ACL Rules to Ingress Traffic and Viewing ACL Configuration
To specify ingress, use the in keyword. Begin applying rules to the ACL with the ip access-list extended abcd command. To
view the access-list, use the show command.
Dell(conf)#interface tengigabitethernet 1/1/1/1
Dell(conf-if-te1/1/1/1)#ip access-group abcd in
Dell(conf-if-te1/1/1/1)#show config
!
tengogabitethernet 1/1/1/1
no ip address
ip access-group abcd in
no shutdown
Dell(conf-if-te1/1/1/1)#end
Dell#configure terminal
Dell(conf)#ip access-list extended abcd
Dell(config-ext-nacl)#permit tcp any any
Dell(config-ext-nacl)#deny icmp any any
Dell(config-ext-nacl)#permit 1.1.1.2
