8. Configure the following match criteria for the rule:
• Sequence Number. Enter a whole number in the range of 1 to 2147483647 that is
used to identify the rule. An extended IP
ACL can contain up to 50 rules.
• Action. Select the ACL forwarding action, which is one of the following:
-
Permit. Forward packets that meet the ACL criteria.
-
Deny. Drop packets that meet the ACL criteria.
•
Egress Queue. If the selection from the Action menu is Permit, select the hardware
egress queue identifier that is used to handle all packets matching this IP ACL rule.
The range of queue IDs is 0 to 7.
•
Logging. If the selection form the Action menu is Deny, you can enable logging for
the ACL by selecting the
Enable radio button. (Logging is subject to resource
availability in the device.)
If the access list trap flag is also enabled, periodic traps are generated, indicating the
number of times this rule was evoked during the report interval. A fixed five-minute
report interval is used for the switch.
A trap is not issued if the ACL rule hit count is
zero for the current interval.
• 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.
•
Interface. For a Permit action, use either a mirror interface or a redirect interface:
- Select the Mirror Interface radio button and use the menu to specify the egress
interface to which the matching traf
fic stream is copied, in addition to being
forwarded normally by the device.
- 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.
•
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. Y
ou 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.
