IPv6 receive ACLs
4
NOTE
You must write this command to memory and perform a system reload for this command to take
effect.
Setting IPv6 Receive ACL to 2048 decreases the size of the Rule ACL sub-partition so that the IPv6
session CAM partition profile is now:
The Rule-based sub-partition size can be increased again by reducing the size of the IPv6 Multicast
sub-partition. Use the following command to reduce the size of the IP Multicast sub-partition to 0.
Brocade(config)# system-max ipv6-mcast-cam 0
Reload required. Please write memory and then reload or power cycle the system.
Failure to reload could cause system instability on failover.
Newly configured system-max will not take effect during hitless-reload.
Syntax: [no] system-max ipv6-mcast-cam num
The num variable specifies the maximum number of IPv6 Multicast entries allowed in CAM. The
range is from 0 through 8192. The default value is 1024.
NOTE
You must write this command to memory and perform a system reload for this command to take
effect.
Changing the size of IPv6 Multicast from 1024 to 0 increases the maximum IPv6 Rule-based ACL
entries by 1024 so that the CAM partition profile is:
Maximum supported size of IPv6 Receive ACLs in CAM profiles
IPv6 rACLs are supported in the following CAM profiles which have space allocated for an IPv6
partition:
•
Default
•
IPv6
•
IPv6 + IPv4
•
IPv6 + IPv4-2
•
Multi-Service
•
Multi-Service-2
•
Multi-Service-3
•
Multi-Service-4
shows the maximum supported size of IPv6 rACLs in supported CAM profiles when the
size of the IPv6 Multicast sub-partition is 0. The maximum number of IPv6 rACL entries will vary
when the number of IPv6 Multicast entries is not 0.
