Creating Named Mac Extended Acls - Cisco WS-CBS3032-DEL Software Configuration Manual

Creating Named MAC Extended ACLs

This example is a named extended access list ext1 that permits ICMP packets from any source to 10.1.1.0
0.0.0.255 and denies all UDP packets.
Switch(config)# ip access-list extended ext1
Switch(config-ext-nacl)# permit icmp any 10.1.1.0 0.0.0.255 log
Switch(config-ext-nacl)# deny udp any any log
Switch(config-std-nacl)# exit
Switch(config)# interface gigabitethernet1/0/2
Switch(config-if)# ip access-group ext1 in
This is a an example of a log for an extended ACL:
01:24:23:%SEC-6-IPACCESSLOGDP:list ext1 permitted icmp 10.1.1.15 -> 10.1.1.61 (0/0), 1
packet
01:25:14:%SEC-6-IPACCESSLOGDP:list ext1 permitted icmp 10.1.1.15 -> 10.1.1.61 (0/0), 7
packets
01:26:12:%SEC-6-IPACCESSLOGP:list ext1 denied udp 0.0.0.0(0) -> 255.255.255.255(0), 1
packet
01:31:33:%SEC-6-IPACCESSLOGP:list ext1 denied udp 0.0.0.0(0) -> 255.255.255.255(0), 8
packets
Note that all logging entries for IP ACLs start with
depending on the kind of ACL and the access entry that has been matched.
This is an example of an output message when the log-input keyword is entered:
00:04:21:%SEC-6-IPACCESSLOGDP:list inputlog permitted icmp 10.1.1.10 (Vlan1
0001.42ef.a400) -> 10.1.1.61 (0/0), 1 packet
A log message for the same sort of packet using the log keyword does not include the input interface
information:
00:05:47:%SEC-6-IPACCESSLOGDP:list inputlog permitted icmp 10.1.1.10 -> 10.1.1.61 (0/0), 1
packet
Creating Named MAC Extended ACLs
You can filter non-IPv4 traffic on a VLAN or on a Layer 2 interface by using MAC addresses and named
MAC extended ACLs. The procedure is similar to that of configuring other extended named ACLs.
You cannot apply named MAC extended ACLs to Layer 3 interfaces.
Note
For more information about the supported non-IP protocols in the mac access-list extended command,
see the command reference for this release.
Though visible in the command-line help strings, appletalk is not supported as a matching condition for
Note
the deny and permit MAC access-list configuration mode commands.
Beginning in privileged EXEC mode, follow these steps to create a named MAC extended ACL:
Command
Step 1 configure terminal
Step 2
