Hi Guys. Because I think my weakest areas today are QOS (Wired and Wireless), dynamic routing, Multicast and autonomous APs I´m working on it with the labs, mainly focused to lab 2 and 3.
About the lab 2 and assuming I have the lab version 2828 and could be corrected in next versions: - Multicast task 2.7: I´m assuming the explanation applies on both AP´s the MULTICAST access list at the interface because there is no subinterfaces in the ethernet interface; if subinterface f0.110 would be and would attach the bridge-group 1 the access-list would be applied on f0.110. am I right?? Two thinks about parrallel scenarios; the same like point to point link between CAT2 and CAT4 but doing with bridges and we don´t permit multicast traffic across the link. Would you think this is valid?? This is a Mixed of deny multicast on AAP1 and Deny multicast in CAT4 (I think the same scenario for the non-root bridge). For AAP1 (root bridge) ip access-list extended MULTICAST-1 deny ip any host 239.10.210.20 permit ip any any Int f0.110 ip access-group MULTICAST-1 in For AAP2 (Non root-bridge) ip access-list extended MULTICAST deny ip 239.0.0.0 0.255.255.255 any permit ip any any Int f0.110 ip access-group MULTICAST in This is only to deny multicast traffic on management interface, for all the VLANs with Multicast routing enabled I supposed this access-list must be applied in the subinterface eth for all the vlans crossing the link, right?? - QOS task 2.8: Is mandatory to create the class-default for VOICE3-PM?, I always believe that if nothing matches with the policy map applied to the interface automatically "matches" with class-default which if not configured set priority to 0. Last one, for QOS on autonomous AP, by default all inbound traffic passing from radio interface to ethernet interface with UP6 are mapped to the ethernet interface with COS 5, and Traffic with UP4 to COS3; but inbound traffic from ethernet with COS 5 and COS3 will maintain their priority when passing from Ethernet to radio interface if you do not enable the "dot11 priority-map avvid" Is this correct??? Because this is the only reason I found for the access-list propossed in the Deployment guide for the 7921G without using this feature. ! ! class-map match-all CONTROL match ip dscp cs3 class-map match-all RTP match ip dscp ef ! ! policy-map VOICE class CONTROL set cos 4 class RTP set cos 6 ! interface Dot11Radio X service-policy input VOICE service-policy output VOICE Thanks for your help and sorry for this "big" mail :)
