- Select the Redirect Interface radio button and use the menu to specify the
egress interface to which the matching traffic stream is forced, bypassing any
forwarding decision normally performed by the device.
• Match Every. From the Match Every menu, select whether all packets must match
the selected IP ACL rule:
- False. Not all packets need to match the selected IP ACL rule. You can configure
other match criteria on the page.
- True. All packets must match the selected IP ACL rule and are either permitted or
denied. In this case, you cannot configure other match criteria on the page.
• Protocol Type. From the menu, select a protocol that a packet’s IP protocol must be
matched against: IP, ICMP, IGMP, TCP, UDP, EIGRP, GRE, IPINIP, OSPF, PIM, or
Other. If you select Other, specify enter a protocol number from 0 to 255.
• Src. In the Src field, enter a source IP address, using dotted-decimal notation, to be
compared to a packet’s source IP address as a match criterion for the selected IP
ACL rule:
- If you select the IP Address radio button, enter an IP address or an IP address
range. You can enter a relevant wildcard mask to apply this criteria. If this field is
left empty, it means any.
- If you select the Host radio button, the wildcard mask is configured as 0.0.0.0. If
this field is left empty, it means any.
The wildcard mask determines which bits are used and which bits are ignored. A
wildcard mask of 0.0.0.0 indicates that none of the bits are important. A wildcard of
255.255.255.255 indicates that all of the bits are important.
• Src L4. The options are available only when the protocol is set to TCP or UDP. Use the
source L4 port option to specify relevant matching conditions for L4 port numbers in
the extended ACL rule.
You can select either the Port radio button or the Range radio button:
- Port. If you select the Port radio button, you can either enter the port number
yourself or select one of the following protocols from the menu:
• The source IP TCP port protocols are domain, echo, ftp, ftpdata, www-http,
smtp, telnet, pop2, pop3, and bgp.
• The source IP UDP port protocols are domain, echo, snmp, ntp, rip, time,
who, and tftp.
Each of these values translates into its equivalent port number, which is used as
both the start and end of the port range.
Select Other from the menu to enter a port number. If you select Other from the
menu but leave the field blank, it means any.
The only relevant matching condition for L4 port numbers is Equal. This means
that an IP ACL rule matches only if the Layer 4 source port number is equal to the
specified port number or port protocol.
