Feb 22, 2014
Known Affected Releases
Symptom: When a mac acl is used with a vlan access-map broadcasts will be blocked - even if they are permitted by using "permit any host ffff.ffff.ffff" in the mac access-list. Here is an example of such a config: mac access-list extended AllowBroadcasts permit any host ffff.ffff.ffff vlan access-map AllowBroadcasts 10 action forward match mac address AllowBroadcasts vlan filter AllowBroadcasts vlan-list 10 This will still block broadcasts in that vlan - even though they are permitted by the mac acl. Conditions: Issue has been seen on all types of blade center switches in the 30x0 series running 12.2(50)SE.
