Purpose Command or Action
extended maclist1
Specifies the type of traffic to permit or deny if the conditions are matched,
entering the command as many times as necessary. { permit | deny } { host src-MAC-addr mask
| any | host dst-MAC-addr | dst-MAC-addr
mask } [ type mask ]
Step 3
• For src-MAC-addr , enter the MAC address of the host from which
the packet is being sent. You specify this by using the hexadecimal
Example:
Switch(config-ext-mac1) # permit
format (H.H.H), by using the any keyword as an abbreviation for
source 0.0.0, source-wildcard ffff.ffff.ffff, or by using the
host
keyword for source 0.0.0.
0001.0000.0001
0.0.0 0002.0000.0001 0.0.0
Switch(config-ext-mac1) # permit
• For mask , enter the wildcard bits by placing ones in the bit positions
that you want to ignore.
0001.0000.0002
0.0.0 0002.0000.0002 0.0.0 xns-idp
• For dst-MAC-addr , enter the MAC address of the host to which the
packet is being sent. You specify this by using the hexadecimal format
(H.H.H), by using the
any keyword as an abbreviation for source
0.0.0, source-wildcard ffff.ffff.ffff, or by using the host keyword for
source 0.0.0.
• (Optional) For type mask , specify the Ethertype number of a packet
with Ethernet II or SNAP encapsulation to identify the protocol of the
packet. For
type , the range is from 0 to 65535, typically specified in
hexadecimal. For
mask
, enter the
don ’ t care
bits applied to the
Ethertype before testing for a match.
When creating an access list, remember that, by default, the end of the access
list contains an implicit deny statement for everything if it did not find a
match before reaching the end.
Returns to privileged EXEC mode. end
Example:
Switch(config-ext-mac1)# end
Step 4
Verifies your entries. show access-lists [ access-list-number |
access-list-name ]
Step 5
Example:
Switch#
show access-lists
(Optional) Saves your entries in the configuration file. copy running-config startup-config
Example:
Switch# copy-running-config
Step 6
startup-config
