VLAN layer 2 VLAN layer 2 jolange77 (TechnicalUser) (OP) 4 Dec 13 09:58 Hi, How I can configure qos on vlan layer 2 (non routable). I need that packets are marked cos 2 (mapped to dscp 18). I am new with qos. Thanks! RE: VLAN layer 2 imbadatthis (TechnicalUser) 7 Dec 13 01:20 you can match to COS inside your class maps, and you can SET DSCP inside them too .. you can also create a COS to DSCP mapping .. and get them tagged that way .. We must go always forward, not backward always up, not down and always twirling twirling towards infinity.
