Extended IPv6 ACLs
4
Syntax: [no] ipv6 access-list name
deny | permit
routing-header-type type-value
Enter a value from 0 - 255 for the routing-header-type type-value parameter to filter packets based
on their IPv6 header type value.
For more information on the syntax, refer to ACL syntax”.
NOTE
The routing-header-type option is separate and independent of the routing option. The
routing-header-type and routing options are mutually exclusive and cannot be used in the same
filter.
NOTE
For more information on configuring the acl-mirror-port command, refer to Multi-Service IronWare
Switching Configuration Guide.
Extended IPv6 ACLs
Configuration considerations for extended IPv6 layer 4 ACL
The following configuration considerations apply to extended IPv6 L4 ACLs:
There are two lookups available for ingress direction. In ingress direction, you can bind an IPv6
layer 4 ACL with IPv4 layer 4 ACLs and layer 3 ACLs on the same port.
Brocade NetIron XMR and Brocade MLX series devices have one CAM lookup for outbound
ACLs.
Only one ingress L2 or IPv6 ACL is allowed per port. However, they cannot be applied
simultaneously.
Layer 4 ACLs filter incoming traffic based on IPv6 packet header fields. The following attributes
can be added to the IPv6 packet header fields:
- VLAN ID
- Source IPv6 address (SIP) prefix
- Destination IPv6 address (DIP) prefix
- IP protocol (SPI matching is not supported for AHP or ESP
- UDP or TCP source port
- UDP or TCP destination port
- TCP flags - established (RST or ACK)
- TCP flags - SYN
- ICMP type and code
- DSCP value
- IPv6 fragments
- source routed packets
- specific routing header type
