Parameters
Usage Guideline
Extended IP ACL only filters IPv4 packets.
The name must be unique among all (including MAC, IP, IPv6 or Expert) access-lists
and the first character of the name must be a letter.
When creating an ACL through assigning a name, an ID will be assigned
automatically. The ID assignment rule will start from the maximum ID of 3999 and
decrease 1 per new ACL.
When creating an ACL through assigning an ID, a name will be assigned
automatically. The name assignment rule is ‘ext-ip’ + “-” + ID. If this name conflicts
with the name of an existing ACL, then it will be renamed based on the following rule:
‘ext-ip’ + “-” + ID +”alt”.
Example
This example shows how to create an extended ACL.

DXS-3600-32S(config)#ip access-list extended Ext-ip

DXS-3600-32S#
sn
(Optional) Specifies the ACE sequence number used. This number must be between
1 and 65535.
protocol
Specifies the name or number of an IP protocol: 'eigrp', 'esp', 'gre', 'igmp', 'ip', 'ipinip',
'ospf', 'pcp', 'pim', 'tcp', 'udp', 'icmp' or an integer in the range 0 to 255 representing
an IP protocol number. To match any Internet protocol. Additional specific
parameters for ‘tcp’, ‘udp’, and ‘icmp’. The ‘ip’ means any IP Protocol.
source
Specifies the source IP address.
source-wildcard
Applies wildcard bits to the source.
host
source
Specifies a specific source IP address.
any
Means any source or destination IP address.
