For extended ACL, TCP, and UDP lters, you can match criteria on specic or ranges of TCP or UDP ports. For extended ACL TCP lters,
you can also match criteria on established TCP sessions.
When creating an access list, the sequence of the lters is important. You have a choice of assigning sequence numbers to the lters as
you enter them, or the Dell Networking operating system (OS) assigns numbers in the order the lters are created. The sequence numbers
are listed in the display output of the show config and show ip accounting access-list commands.
Ingress and egress Hot Lock ACLs allow you to append or delete new rules into an existing ACL (already written into CAM) without
disrupting trac ow. Existing entries in the CAM are shued to accommodate the new entries. Hot lock ACLs are enabled by default and
support both standard and extended ACLs and on all platforms.
NOTE: Hot lock ACLs are supported for Ingress ACLs only.
CAM Allocation and CAM Optimization
The S5000 supports the CAM allocation and CAM optimization.
For more information, refer to the following:
• User Congurable CAM Allocation
• CAM Optimization
User Congurable CAM Allocation
Allocate space for IPV6 ACLs by using the cam-acl command in CONFIGURATION mode.
The CAM space is allotted in lter processor (FP) blocks. The total space allocated must equal 13 FP blocks. (There are 16 FP blocks, but
System Flow requires three blocks that cannot be reallocated.)
The default CAM allocation settings for ingress ACL and QoS regions on an S5000 are:
• L2 ACL(l2acl): 4
• L3 ACL (ipv4acl): 4
• IPv6 L3 ACL (ipv6acl): 0
• L3 QoS (ipv4qos): 2
• L2 QoS (l2qos): 1
• L2PT (l2pt): 0
• MAC ACLs (ipmacacl): 0
• ECFMACL (ecfmacl): 0
• VMAN QoS (vman-qos): 0
• VMAN Dual QoS (vman-dual-qos): 0
• FCoE ACL (fcoeacl): 2
