- 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 selected radio button for the action 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 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 radio button and use the menu to specify the egress interface
to which the matching traf
fic 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.
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:
