Access Control Lists (ACLs) for the Series 3400cl and Series 6400cl Switches 
Configuring and Assigning an ACL 
Syntax:  [no] access-list 
Creates an ACE in the specified (100-199) access list and:  
•  Indicates the action (deny or permit) to take on a packet  
if there is a match between the packet and the criteria in 
the complete ACE.  
•  Specifies the packet protocol type (IP, TCP, or UDP). 
•  Specifies the source and destination addressing options  
described in the remainder of this section. 
•  Allows optional ACL logging where a packet has a match 
with a deny ACE. 
If the ACL does not already exist, this command creates the  
specified ACL and its first ACE. If the ACL already exists,  
this command adds a new, explicit ACE to the end of the  
ACL. For a match to occur, the packet must have the source  
and destination IP addressing criteria specified by this  
command, as well as any protocol-specific (TCP or UDP  
port number) criteria specified by the command. To create  
a named ACL, refer to “
Configuring a Named ACL” on page  
10-54. 
< 100-199 > 
Specifies the ACL ID number. The switch interprets an ACL  
with a value in this range as an extended ACL. 
Note: To create an access list with an alphanumeric name 
instead of a number, refer to 
“Configuring a Named ACL” 
on page 10-54. 
< deny | permit > 
Specifies whether to deny (drop) or permit (forward) a packet that 
matches the ACE criteria. 
< ip | tcp | udp > 
Specifies the packet protocol type required for a match: 
•  ip — any IP packet 
•  tcp — only tcp packets 
•  udp — only udp packets
