Configuring IPv6 ACLs
6
DRAFT: BROCADE CONFIDENTIAL
Unsupported commands and message types
The following commands are not supported for IPv6 ACLs:
• ipv6-operator flow-label
• ipv6-operator fragments when any protocol is specified. The fragments option can be specified
only when permit ipv6 or deny ipv6 is specified. If you specify tcp or any other protocol instead
of ipv6, the fragments keyword cannot be used.
• ipv6-operator routing when any protocol is specified. (The same limitation as for ipv6-operator
fragments.)
tcp Indicates the you are filtering TCP packets.
udp Indicates the you are filtering UDP packets.
tcp-udp-operator <source-port-number>
|<destination-port-number>
The tcp-udp-operator parameter can be one of the following:
• eq: The policy applies to the TCP or UDP port name or number
you enter after eq.
• gt: The policy applies to TCP or UDP port numbers greater than
the port number or the numeric equivalent of the port name
you enter after gt. Enter "?" to list the port names.
• lt: The policy applies to TCP or UDP port numbers that are less
than the port number or the numeric equivalent of the port
name you enter after lt.
• neq: The policy applies to all TCP or UDP port numbers except
the port number or port name you enter after neq.
• range: The policy applies to all TCP or UDP port numbers that
are between the first TCP or UDP port name or number and the
second one you enter following the range parameter. The
range includes the port names or numbers you enter. For
example, to apply the policy to all ports between and including
23 (Telnet) and 53 (DNS), enter the following: range 23 53. The
first port number in the range must be lower than the last
number in the range.
The <source-port-number> and <destination-port-number> for the
tcp-udp-operator is the number of the port.
ipv6-operator <value> Allows you to filter the packets further by using one of the following
options:
• dscp: The policy applies to packets that match the traffic class
value in the traffic class field of the IPv6 packet header. This
operator allows you to filter traffic based on TOS or IP
precedence. You can specify a value from 0 through 63.
• fragments: The policy applies to fragmented packets that
contain a non-zero fragment offset.
NOTE: This option is not applicable to filtering based on source or
destination port, TCP flags, and ICMP flags.
• routing: The policy applies only to IPv6 source-routed packets.
NOTE: This option is not applicable to filtering based on source or
destination port, TCP flags, and ICMP flags.
log Allows statistics that match the ACL statement to be entered in the
syslog.
