Layer 2 Switching Commands 282
In order to provide the greatest amount of flexibility in configuring ACLs, the
permit/deny syntax allows combinations of matching criteria that may not
make sense when applied in practice.
Port ranges are not supported for ACLs configured in egress (out) access-
groups. This means that only the eq operator is supported in an egress (out)
ACL.
The protocol type must be sctp, tcp or udp to specify a port range.
The fragment keyword is not supported for ACLs configured in egress (out)
IPv4 access-groups.
Rate limits are only valid for permit rules.
Any – is equivalent to 0.0.0.0 255.255.255.255 for IPv4 access lists
Host – indicates specified address with mask equal to 255.255.255.255 and
address 0.0.0.0 for IPv4.
The command accepts the optional time-range parameter. The time-range
parameter allows imposing a time limitation on the IP ACL rule as defined by
the parameter time-range-name. If a time range with the specified name does
not exist, and the IP ACL containing this ACL rule is applied to an interface
or bound to a VLAN, then the ACL rule is applied immediately. If a time
range with the specified name exists, and the IP ACL containing this ACL
rule is applied to an interface or bound to a VLAN, then the ACL rule is
applied when the time-range with a specified name becomes active. The ACL
rule is removed when the time-range with a specified name becomes inactive.
An implicit deny all condition is added by the system after the last MAC or
IP/IPv6 access group if no route-map is configured on the interface.
Every permit/deny rule that does not have a rate-limit parameter is assigned a
counter. If counter resources become exhausted, a warning is issued and the
rule is applied to the hardware without the counter.
If a permit|deny clause is entered with the same sequence number as an
existing rule, an error is displayed and the existing rule is not updated with
the new information.
